Residential Roof Replacement Step-by-Step

Residential Roof Replacement  GreenPoint Roofing DenverAt GreenPoint Roofing, our team of licensed and insured roofing contractors works closely with clients to help them understand everything that goes into their residential roof replacement.

Along with choosing materials, there is a specific process to follow to ensure optimal results. It takes experience to understand that skipping steps will lead to a mediocre roof replacement job and less than perfect outcomes. That’s the difference between us and the other guys.

Here is a simple overview of the process for you residential roof replacement project so that you can understand what to expect along the way.

Remove Existing Materials

First things first, we must remove all of the layers that have been added to the roof over the years. Many times, instead of replacing the roof entirely, a homeowner will choose to add roofing layers. So, your roof may have quite a few of these layers that have added up over the years. We start by taking off the shingles, no matter what type of material. They may be slate or even sheeted roof deck. It all has to come off before we can add a new roof.

We remove all flashing all the way down to the roof deck sheathing. Additionally, the roof tarpaper has got to go. We have got to get to the bottom of it all in order to really see what is going on. Most shingles manufacturers will void the warranty if installed over any other materials. Hence it is essential to remove everything, all the way down to the wood roof.

Replace Damaged Wood

Once we can actually see the condition of the wooden roof, we will be able to deduce what needs replacement. Not until all of the layers are off, can we truly see what needs to be done with the wood roof. Sometimes, this can reveal rotten wood that must be replaced in order to avoid constant problems with a leaking roof. All of the volatile wood must be replaced so that it is strong and ready to support the weight of new roofing materials.

Install the Underlayment

Above the sheathing and below the shingles lives the underlayment. Either of the most popular materials, titanium or tarpaper, can be used. Although costlier, titanium offers a better reflection and generally comes with a warranty if the replacement shingles fail in any way.

Apply Ice and Water Shield

This component will significantly protect against the ravages of ice and snow during the colder months. This is applied to the gutter end lines and must be sealed with a gutter-to-fascia seal cap or gutter apron in order to work efficiently.

Add Needed Ventilation

Many houses do not have an adequate ventilation design. It is essential that air can smoothly flow and escape into the attic and then out the peak roof area. Our residential roof replacement experts will make sure that airflow design is included in the beginning rows in each shingle starter area.

Apply Under-Row Starter Shingles

On the first starter row of the roof area to be shingled goes the under-row starter shingles. This prevents the bond from exposure, as it is not water resistant and could prove to be a weak point. It is crucial that no tabs or bonds overlap here.

Install Drip Edge

Drip edges will save your home from unwanted moisture, rot, stained siding, soil erosion, and flooding. These extend over the edge of your new roof just enough to make sure all water lands into the gutter and not behind it instead. Drip edges must be installed and fitted correctly, as they will save your roof from irreparable damage down the road.

Add a Hip and Ridge Cap

A hip and ridge cap will create more of a finished look as well as help with avoiding water leakage into the house, a must-have for any residential replacement roof project!

Add Flashing and a Silicone Sealant

Using aluminum, copper, or another durable material, we install flashing. The best way to seal it in is with a silicone-based caulk. Silicone is the optimum choice as it dries slower than asphalt or other rubber-based products, which is better suited for this purpose.

Add Pipe Boots

Around pipe stacks or other roof protrusions on the entire roof, we install new pipe boots for best results during a residential roof replacement. Again, these help with water flow management and protecting protruding pipes and the roof below adequately.

Install Diverters

Keep water diverted and easily flowing off of the roof with the installation of diverters, especially behind chimneys and stop wall areas. You will be glad to have this vital step covered when our spring and summer storms roll through. They’re vital for the longevity of your roofing!

Lay All the Shingles

With the right, high-quality shingles, you won’t need to schedule shingle replacement for quite a while. While the cost of shingles varies, the quality differs even more. A dimensional shingle is the best option as it provides both durability and aesthetically pleasing results. The better the shingles used and the better the workmanship, the longer your new roof will last!

Don’t Forget Gutter Guards

As long as we’re up on your roof, we can also install gutter guards to keep debris out of gutters. Some cheap gutter guards will only last about a year and will soon start sagging and breaking. Aluminum diamond grates are an excellent option. They keep out debris efficiently, will not rust, allow water to flow continuously, and will stand the test of time, continuing to protect your home year-round. Be sure to ask us for more information.

Knowing the basics of residential roof replacement can help you make the best decision when it comes time to choose a roofing contractor and getting your project off the ground. There is no reason to settle for less than the best! At GreenPoint Roofing, we know the ins and outs of roof replacement and will follow industry best practice to the letter so that you get the most out of your new roof replacement in Colorado.

Get to Know Your 6 Roof Replacement Materials

roof replacement materials GreenPoint Roofing DenverWhen designing or renovating a home, one of the most important factors to consider is your roof which has two jobs, protecting everything below it and adding value to your home.

You’ll typically have six roof replacement materials to choose from, each having a different effect on the functionality, insulation properties, aesthetics, and longevity of your roof.

At GreenPoint Roofing in Longmont, we can help you make the best choice for your home, your budget and your family! We provide expert roofing services on all residential and commercial projects.

Considerations for Roof Replacement Materials

When weighing the pros and cons of your options for roof replacement materials, it’s important to talk over the following factors with your GreenPoint Roofing expert: 

  • Climate Suitability – Will this kind of home roofing material protect you from specific local weather conditions such as high temperatures, heavy rainfall, snow, hail, and the wind?
  • Cost – Calculate the square footage of your roof and the total cost before saying yes to a new roof. Does it fit your budget? Will the cost pay itself back over time? 
  • Weight – Does this roofing material require additional framing for support and a professional installation?
  • Fire Safety – If your area has restrictions on roofing materials, does it meet the fire code specifications?
  • Aesthetics – Does the appearance of the material fit with the style of your home and is it available in the color or design you are looking for?

Asphalt Shingles

Asphalt shingles are the most popular of the roof replacement materials and for a good reason. They are widely available, inexpensive, and easy to install. If you are looking for a fast and affordable option, asphalt shingles offer an excellent solution. Asphalt shingles are the most common on the market and are usually available in a few different colors. You can often find asphalt shingles on traditional suburban style homes, but they can work well with many different architectural styles.

Some disadvantages of asphalt shingles include their limited lifespan of around 20 years, variations in quality, and weak insulation properties. It is possible to have your shingles reinforced with fiberglass or cellulose without altering their appearance. For homes in freezing climates, it may be worth investing in additional insulation when using asphalt shingles. To avoid having to make these modifications and incur extra costs, you could consider choosing a different, harder-wearing roofing material.

Wood Shingles and Shake

Wood shingles, or their more rustic counterparts, hand-cut wood shakes, can certainly add character and charm to your home’s new roof in Longmont. Typically made from cedar, redwood, or pine, wood roofing materials have been used for centuries with great success. They tend to gradually weather to a grayer tone and last from 25 to 30 years

When it comes to roof replacement materials, wood is not practical for all climates. In areas with hot, dry weather, fire codes may prohibit them or require that they’re treated with a fire-resistant coating. In wet climates, wood shingles can weather quickly and are more likely to mold, rot and split over time.


Slate roofs are beautiful, sustainable and built to last. Slate is a very hard-wearing, fire-resistant material that can be used successfully in all climates. You can choose from a number of different shades of green, red, gray, and purple slate to add a personalized appearance to your home

Due to the material’s weight, a slate roof will usually require extra framing for support and professional roof installation. Slate is one of the most expensive options for roof replacement materials, around $600 per square. With a typical lifespan of 50 to 100 years, a slate roof may be worth the investment.

Clay or Concrete Tiles

Clay tiles can create a wonderfully textured appearance and work very well on Mission, Mediterranean, and Spanish style homes. Rounded terracotta tiles not only look great but they are also practical with their ability to quickly drain water. Clay tiles are long-lasting and can be found in different shapes including flat, scalloped, and ribbed. If you opt for concrete tiles, you can save some money and benefit from a higher energy efficiency rating.

Clay and concrete tiles are substantial enough to need additional framing and a professional installation, however, they’re one of the most durable roof replacement materials. The classic look of terracotta tiles comes with a high price tag. After slate, clay tiles are the second most expensive roofing material.

Synthetic Roofing Products

Synthetic roofing products have been designed to mimic the appearance of traditional wood, slate, and tiled roofs. Usually, the actual materials are made from rubber, plastic or polymer blends. This means that synthetic roofing materials are much lighter than traditional shingles and tiles. They are sturdy, easy to maintain and can be installed without additional framing. Synthetic roofing is available in a wide range of styles, colors, and textures, allowing you to choose your favorite aesthetics without having to deal with the expense, maintenance, and fragility of traditional materials.

The major disadvantage of synthetic roofing materials is the lack of information we have on their longevity. These roof replacement materials are so new that we have not had the chance to see how they endure long-term weathering, although many manufacturers offer a warranty of up to 50 years.

Before buying, it is a good idea to view a synthetic roof that has been in place for at least 10 years in your area. This will give you an idea of the rate of wear to be expected.

Metal Roofing

Metal roofing materials are available in stainless steel, copper, aluminum and zinc. This lightweight material can be installed in panels or shingles and is a good option for those living in extreme environments. Metal roofing is useful when designing an efficient home as the material offers a high solar reflectance and can be suitable for use in harvesting rainwater. Metal roofing materials will last considerably longer than asphalt or wood.

Prices on metal roofing can vary widely, from $100 to $800 a square. Some homeowners do not find the appearance of metal roofing attractive and prefer to use traditional materials, especially on homes designed with specific architecture in mind. Depending on the type of metal used, these roofs can oxidize and change color over time.

We have over 20 years of experience in providing quality roof installation and repair services. You can rely on our team to offer a wide variety of options in roofing materials and designs, customized to your individual needs.

5 (Undeniable) Signs that Your Roof Needs to be Replaced

Roof Needs to be Replaced GreenPoint Roofing DenverAs a general rule, you’ll get around 20-25 years before your roof needs to be replaced. Factors such as the climate you live in, as well as our Colorado hail, and the general upkeep regimen can also add or subtract years from this ballpark figure.

So, if you’re in the market to buy a house here in Longmont or the Denver metro area, it’s a good idea to request information on the age of the roof and the entire home. Once you know the approximate age of a roof, you can then estimate how many more years it should last.

And if you already own or rent a home with an older roof, watch for these signs that your roof needs to be replaced. Even if you have a relatively new structure, keep an eye out for issues after severe storms. You never know when a problem could come up.

Getting to know the following signs means that you can be aware of the condition of your roof and make an informed decision when it comes time to repair or replace it.

#1 It’s Just Not Working Anymore

A leaking roof is the most obvious sign that you need a complete replacement of your home roof. If you’re getting having mold issues, or find water spots or bubbles on ceilings and walls, your roof could certainly be the culprit.

For a younger roof, this is often the result of ignoring maintenance. And once a serious leak occurs, you will risk causing extensive damage to the point that your roof needs to be replaced. The best approach is to be vigilant and call in the professionals for regular inspections.

#2 Sagging & Dark Spots in the Attic

Regular visual inspections from the inside can give homeowners a good idea of the condition of their roof. From the inside of your attic, you can check for areas of sagging roof deck or water damage.

Examine the inside of the roof for mold growth, dark spots, or trails. This discoloration could be water damage, especially if it occurs near the seams and joints of the roof. You can also test your insulation for moisture.

Check during the day to see if sunlight enters through unsealed gaps in your roof. If sunlight can enter, that means rain, snow and cold air can also make its way into your home.

#3 Loose Granules & Exterior Issues

From the exterior of your home, you should regularly check your gutters for asphalt granules. Older shingles can start to lose their structural integrity, and one of the first signs of this is loose granules. 

Without walking on the roof or putting yourself in a dangerous position, you should then visually inspect the shingles of your roof. If you notice a couple are missing, or that they are starting to curl upwards at the edges, this could indicate they are nearing the end of their functional lifespan.

Other key exterior issues to look out for include broken or damaged metal flashing, extensive mold coverage, drainage problems and a high percentage of cracked shingles.

If you notice any of the warning mentioned above signs, please don’t wait. Get in touch with a qualified and licensed roofing contractor right away. Our specialists here at GreenPoint Roofing can provide an inspection to determine if your roof needs to be replaced – or if it’s a candidate for repair. Call today!

Is There Such Thing as a Hail-Proof Roof?

At GreenPoint Roofing, one of the common types of roof damage we encounter is caused by hail. For homeowners across Colorado, hail is an inevitable reality.

Known as Hail Alley, the Front Range of Colorado and eastern plains of Wyoming experience the highest frequency of big hailstones in all of North America. They cause an astronomical level of damage to cars, homes, and property each year. In fact, it’s estimated that over the last decade, these storms have cost over $1.7 billion in damages.

Because you live in this high-risk zone, you may be wondering if there’s such thing as a hail-proof roof instead of just waiting for the day when your roof needs to be replaced. While we’d love there to be a product that could fend off devastating golf-ball, even softball-sized hail, there just isn’t a proven method yet.

The Closest Thing to a Hail-Proof Roof

While there are no guarantees, there are a number of factors that can help protect your roof. With the right materials and design, you can give your roof better protection and a fighting chance when the next storm rolls around.

The most important thing to avoid when reinforcing your roof against hail is to re-roofing over existing shingles. For best results, remove the old shingles and replace them with all new roofing materials. Here are a few more considerations.

Choosing the Correct Shingles

Generally, shingles made with polymer-modified asphalt will be more resistant than those made from conventional oxidized asphalt. A more precise way to measure the hail-resistance of shingles is to look at its rating from Underwriters Laboratories which designed a roofing materials test by dropping steel balls onto them and then classifying them according to their hail resistance on a scale of 1 to 4.

  • A standard wooden shake will probably receive a Class-1 UL rating, due to its high susceptibility to damage from hailstones.
  • Polymer-modified asphalt or concrete tiles are most likely to boast the highest rating of Class-4 UL due to their strength and resistance.

The Right Roof Design

Another factor that contributes significantly to hail-resistance is the pitch of your roof. Flatter roofs will suffer from a more forceful impact when hit by hailstones. Steeper roofs benefit from the inclined angle, as the hailstones are more likely to glance off the roof, saving it from having to absorb the full force of impact and finding out that your roof needs to be replaced. A roof pitch over 6:12 will offer better resistance to hail damage.

The Right Roof Decking

Additionally, for maximum protection, you should opt for rigid roof decking. Tongue and groove style decking or well-supported plywood sheathing will give the shingles extra support. Using a thin, single layer underlayment is another way to fortify a shingle roof. Modern materials are thinner, stronger and allow for better air permeation than traditional asphalt-saturated roofing felts.

If you have reason to install an entirely new roof or fully remodel the structure of your home, you can adjust your shingle type, roof pitch, decking and underlayment to create the optimum design for a more hail-proof roof. For existing structures, the most cost-efficient changes are updating the underlayment material and switching to high-quality shingles with a better UL rating.

While a hail-proof roof is not yet a reality, hail-resistant is within reach. For more information on making roof updates, please feel free to contact GreenPoint Roofing.

5 Questions to Ask Your Commercial Roofing Contractor

commercial roofing contractorDoing some research before choosing a commercial roofing contractor is the only way to kick off your project on the right foot.

For commercial, agricultural or industrial developments, it is particularly important to ask your commercial roofer some key questions before hiring them.

If you are a property developer, take a look at this guide from GreenPoint Roofing in Longmont, Colorado before making your decision on a commercial roofing contractor.

1. Ask Your Commercial Roofing Contractor if They’re Licensed

All roofers, whether residential or commercial, should be able to provide you with details of their operating license and insurance.

You have a right to review this and check that they are indeed licensed and insured to work within your municipality and that they have permission to carry out the specific type of commercial work for which you plan on contracting them to complete.

2. Request Referrals and Check Reviews

Another very basic piece of information to request is the details of their experience; how long they have been in the industry, examples of previous completed projects and referrals.

You can check reviews on Yelp, Angie’s List or HomeAdvisor can give an indication of their reputation. A high rating by the Better Business Bureau is another reliable indicator of quality.

3. Get to Know their Commercial Roof Offerings

Depending on your project and the functions of the planned building, there are different styles of commercial roofing to consider.

The most common options used in commercial roofing today include modified bitumen roofing, liquid-applied roofing or built-up roofing (BUR). If you need a flat roof, BUR technology offers the best option to ensure a long-lasting and highly leak-resistant roof.

A separate base layer, ply layer, and cap layer are installed to create a seam-free membrane which will not suffer cracks when expanding and contracting due to temperature changes.

4. Make Sure They Can Accommodate Your Needs

Make a list of your requirements including fireproofing, insulation, weather resistance, soundproofing, and aesthetics. If you are considering installing solar panels, skylights or a rooftop garden or terrace, remember to discuss this with your potential roofer. It is best to ensure they have the necessary technology and skills to install the roof with the features you need.

Do you expect your commercial roofer to go the extra mile and also install any guttering and drainage systems, siding or additional features?

For each item on your list, get a clear answer from your commercial roofer before proceeding.

5. Clarify Guarantees and Warranties Before Moving Forward

Don’t forget to ask about warranties offered by your commercial roofer. Most manufacturers will provide at least some guarantee on their roofing products. Some roofing companies will also offer additional warranty agreements.

For example, GreenPoint Roofing offers a workmanship guarantee of five years on every job completed.

Consumers should be aware of their responsibilities to prevent voiding the warranty. These can include keeping records of maintenance checks.

Working your way through this list of questions to ask before hiring a commercial roofer will give you the opportunity to select a qualified contractor capable of completing the job. Choosing the right commercial roofer is absolutely worth it when you think about the time and money saved with a stress-free, high-quality roof installation. 

Time for a New Roof?

Time for a New Roof GreenPoint Roofing DenverWondering if it’s time for a new roof? While perhaps not on your list of New Year’s resolutions, it’s a good question to ask. And today, GreenPoint Roofing in Longmont offers our tips to help you determine the condition of your roof. With some basic knowledge about roofs, roof repair, and roof replacement, you can more easily decide what is best for you, your family and your home this year.

We all need a roof over our heads. GreenPoint can help to determine just how solid your roof is and give an estimation of its lifespan. Keeping your roof in good shape will increase your home’s resale value if you choose to sell at any point. Take a look at this overview to determine if it is time for a new roof.

Early Detection

With regular roof inspections, you will be ahead of the game if there is an issue with your roof. Finding and addressing a roof problem early can make a huge difference between paying much less and paying so much more than you ever imagined. It breaks down like this:

  • Minor repairs
  • Major repairs
  • Replace the entire roof
  • Repair or replace the structure below

Visual Inspection of Interior and Exterior

National Roofing Contractors Association (NRCA) recommends doing a roof inspection twice annually. This allows issues to be found early which is always better. The sooner an issue is found, the sooner it can be resolved. The smaller the problem, the easier it is to fix. You get the picture. As time goes by, a small issue could easily snowball into a complete replacement of your roof.

To stay ahead of the game, inspecting in the fall and spring make the most sense. If problems are found or it’s time for a new roof, a spring repair will be better than a summer one, but if it drags out, you will still have good weather to enjoy. A fall repair job is much better than finding out in the winter when temperatures drop.

So, grab a flashlight and head upstairs to take a look at the interior of the roof. If anything appears off, do not brush it aside. Make a note of it to discuss with your roof inspector immediately.

Interior Inspection

During a roof inspection, your or your roofing professional should look for any signs of:

  • Sagging
  • Leaking
  • Water damage
  • Dark spots or discoloration
  • Light shining through from outside

Exterior Inspection

A roofing inspection also includes looking for any signs of moisture penetration:

  • Mold
  • Mildew
  • Algae
  • Rot
  • Curling
  • Blistering
  • Buckling

Be aware that water travels to the lowest point then drips. So, the point at which you find the damage could start from a hidden location on the inside of the roofing or shingles.


Look for any signs of:

  • Torn, cracked, bald or missing shingles
  • Shingle granules appear like sand

Damaged Flashing

Loose material of any sort especially around the chimney, pipes, vents, etc.


Check the following:

  • Drainage systems are functioning properly
  • Angled to allow water to escape
  • Gutters and downspouts securely attached
  • Free of any debris including animal nests


Check to see that vents have an outlet completely outside of the home, not just into the attic. This includes the dryer, bathroom, and kitchen vents.

Roofing Materials

Depending on where you live, different roofing materials will work better than others. Your roof is obviously working to a point, but if you find any issues upon inspection, you know that each material will have its downfalls. For this, be sure to consult with a professional roofing service to get the best advice for your area and your particular roof.

For instance, tile is a very popular look and can be a great option, even lasting up to 100 years. But checking on the tiles can be a tricky business. Do not walk on the tiles to check the roof, as they can easily break. Bring in a professional to look for missing or broken tiles, as well as replace them.

When a cedar roof is in need of repairs or replacement, signs of deterioration include splitting and disintegration of the cedar tiles. A cedar roof typically lasts about 20 years. Roofing with wooden shakes often suffers from wood-boring pest damage including carpenter ants and termites. Concrete, on the other hand, is a long-lasting roofing option with little need for replacement.

New Roofs

If you notice visible signs of damage on your roof but your roof was adequately installed within 15-20 years ago, it may not be time for a new roof. A simple repair may be an effective enough strategy to take, as opposed to opting for an entirely new roof replacement. A trusted and licensed contractor will be the professional to ask which route is honestly the best to take.

New Roof Materials

When it’s time for a new roof, you’ll want to choose your material thoughtfully. Wood and asphalt shingles are not ideal for dry climates as they are not very fire-resistant. For this, metal, tile, and slate are much better options if your budget will allow. Snowfall is another significant factor. If your area receives heavy snowfall, then perhaps installing a standing-seam metal roof is a good option. Its durability yet lightweight construction is a good option is snow-ridden areas, as they send the snow sliding down before it can start melting and posing a potential problem with leaks.

With tile or slate roof construction, you must have your roof contractor determine if your structure is strong enough to support those types of materials as they are extremely heavy. And remember, the price cannot always be the only determining factor when it comes to choosing a new roof material. Safety and feasibility requirements must be met first.

If it is time for a new roof, do not try to replace the roof yourself. Professionals have the tools and skills to do it right without harming anyone or anything. Having a roof over our heads is something we all require, so keep yours in good shape with help from GreenPoint Roofing this year. We offer roof inspection services and all roofing repair and replacement services. Let us know how we can help this New Year so you can enjoy it, stress-free.

New Residential Roof Considerations

roof GreenPoint Roofing DenverCheck out these new residential roof considerations from GreenPoint Roofing in Longmont. Learn what points to think about when approaching the topic of getting a new roof. Will you keep the old layer or tear it off? What roof material will work best for your home? How will the age of your current roof affect your choice? Today, we discuss all of this and more.

To get started on learning what to consider when it comes time to re-roof your home in Colorado, check out the following info from our experts at GreenPoint.

Current Roof Age

Your home’s roof is one of the most important features that keep you and your family dry and safe from the elements. If it is working great and there are no issues, great. But if you are noticing leaks, curling shingles, and any number of other symptoms that the roof is not in as good of shape as it once was, the sooner that you can get it addressed the better. The longer one waits to repair or replace a roof, the more damage will inevitably occur which of course leads to more complex and expensive repairs.

If you installed the current roof, and don’t remember when it was, look through your old paperwork to find out when you should be looking into a new residential roof. This is going to help you determine what to do. If you were not the owner of the home when the last roofing was done, find out from the previous owner, precisely what was done and when the last new roof was installed. Then you can begin to determine your next move.

A general guideline for modern day roofing includes:

  • Shingles last about 20 years
  • Architectural shingles last up to 30 years
  • Galvalume metal roofing lasts anywhere from 24-45 years
  • Concrete tiles last between 35-50 years

So if your roof is older or nearing any of these ages, it is time to think about a new residential roof. Plus, experiencing any roof issues further justifies that it’s the right time for a new roof.

To Layer or Not to Layer

The next question is whether to simply add a new roofing layer or tear off the old one first and start fresh. There are a couple determining factors. If you have curling shingles or uneven roofing, these are sure signs that a tear-off is a better option. It’s not a good idea to put a brand new roof layer over a roof problem. It will merely negate the time, money and effort that went into the new roof installation.

Building codes allow up to two roofing layers total. So that means, if you have a roof on the home, you can put up to one layer on top of that. If you already have a roof and another roof layer, you must tear it off and start with a new residential roof. You roofing contractor can help to determine the best course of action here. In fact, they will be invaluable in the deciding process, so make sure that you trust and understand your roofing contractor.

Roof Frame Condition

If you are thinking to simply add the new roof instead of tear off the old one, then the condition of the roofing frame must be addressed. The combined weight of a new roof on top of an old one is substantial, and some homes just were not built to withstand the pressure efficiently. Your roofing contractor will also provide a thorough inspection of the roof frame to help determine the best approach here.

Type of Roofing

There are a couple of factors to take into account in regards to what roofing material to choose for your new residential roof. Aesthetics, cost and life expectancy, should all be considerations in the process to determine the best choice. If you have any leeway in your budget to choose anything other than the most affordable option, asphalt shingles, it is highly recommended that you do so.

By choosing concrete or metal roofing, you will both increase the value of your home as well as the life expectancy of the roof. Your roofing contractor can review the benefits and drawbacks of each option so that you have the full picture and can make the best decision for your home.

The Work

Unless you are experienced in construction, taking on a roof replacement is not recommended. The details involved in tearing off and installing a new residential roof are many. That is why roofing contractors can do such a good job. They have the knowledge and skills to complete the project faster and with better results. 

Who to Trust

Be sure that you feel good about the roofing contractor that you choose to do the work on your home. This is essential to the final results turning out right. The trusted team at GreenPoint Roofing is a reliable source to turn to when you need help with your roofing system. We are dedicated to client satisfaction each and every time.

One of our experienced roofing contractors will come to your home at your convenience to evaluate and help determine the best course of action for your particular roof.

What are Signs that a Roof is in Trouble?

roofer GreenPoint Roofing DenverToday, the GreenPoint Roofing experts in Longmont want to shed light on signs that a roof is in trouble. Hopefully, this information will help you understand the current condition of your roof, what symptoms to look for and what may be a threat to your roof’s structural integrity. Of course, if you find that your roof is showing any of these signs, give us a call for an inspection, repair or complete roof replacement.

Granules in Your Gutters

One of the many signs that a roof is in trouble is finding a large number of granules washing out in the gutters and downspouts. A small amount of roof tile granules washing off is not a significant concern, but if the amount continually increases, this should set off alarm bells.

Granules washing off in large amounts signifies that the shingles are deteriorating and perhaps nearing the end of their functional lifespan. This happens when the shingles simply get too old to perform their duty. Aging shingles are a problem because they no longer can protect the roof against the intense UV rays streaming down every day. They can become brittle and start cracking, leading to other possibly more significant problems such as leaking.

Exposed shingles without any remaining granules with bald spots will inevitably lead to more roof issues. So, go ahead and give your gutters and downspouts a once-over to check for washed out granules. As always, give us a call at GreenPoint Roofing for professional help, so you don’t have to climb up on the ladder yourself.

Shingles Cracking & Disintegrating

Once the shingle granules have been washed away or fallen off over time, the shingles themselves will start cracking from the exposure to sunshine. Without these protective granules, they’ll become brittle and start breaking apart which will only lead to more severe roof issues.

This extreme sun exposure breaks down the integrity of the shingles, and they cannot protect your roof as they did when they were new. Cracking shingles is one of the clear signs that a roof is in trouble and most likely require roof replacement.

Water Spots Inside Your Home

No one wants to see water spots on their ceiling. If this is the case, then your roof might be the culprit. You most definitely have an issue, but it could be any number of things including a roof leak, plumbing problems, condensation, or a window seal issue. Hire a professional to locate the source of the water spots. However, if you notice the spots appearing, darkening, or growing after it rains, this is a good indicator that a roof leak is the problem.

Finding a slow leak, only a couple drops at a time, can be harder than finding a bigger leak. Water can travel horizontally until it accumulates enough to drip and fall. Hence, a leak can start in one area and travel along, revealing itself in another area. Water can move along the wood or roof panels in the attic, drip into the insulation, and any number of ways, not just a straightforward drip down.

Water Spots Exterior

Finding water spots on the outside of your home also makes our list of signs that a roof is in trouble. Most likely, the step flashing, where the roof meets anything coming in or going out of the roof such as chimneys, vents, and windows is damaged, loose, missing, or rusted.

Again, if you notice the exterior water spots after rainfall, the problem is most likely the flashing. You will want to hire a professional roofer to repair the flashing as it is a delicate point of contact where the roof joins the adjacent siding. Not addressing the problem will cause it to grow, potentially leading to the need for a total tear-off and roof replacement.

Black Stains of Roof

Finding black stains on the roof is typically a sign that algae is present. Most homes in Colorado do not have to deal with this, but if your home is very shaded or in a mountainous area, your roof is more susceptible to algae growth. Fortunately, finding algae is not a very serious issue for your roof. Keep the algae at bay by installing strips of zinc with fungicide on the roof ridge. When it rains, the fungicide will kill off the algae. Also, consider replacing worn out roof tiles with algae-resistant shingles.

Shingles Missing

There are a couple of reasons for finding missing shingles on your roof. Either the sealant strip below the shingles has been damaged, or an animal is the culprit. In the case that it is a pest of some sort, be sure to trim back any tree branches that come close to your roofline. These are highways for critters of all kinds and an easy way for them to access your roof and cause insurmountable damage.

In the instance of sealant strips, they help to hold the shingles in place. But if they become worn out and brittle, they will stop doing their job. With degrading sealant not helping to maintain the shingles in position, in a storm or with high winds, the shingles can fly off. Because shingles use an overlapping pattern to keep water from penetrating the roof, missing shingles will most likely lead to roof leaks.

Shingles Cupping

Noticing that the shingles on your roof are cupping is a bad sign that the attic is not well-vented. The attic is heating up considerably and frequently, which is aging the shingles prematurely. This results in cupping. You will want to replace them and more likely re-shingled the roof entirely. 

Roof Leaks when Temperature Fluctuates

When the temperature of the roof fluctuates from cold to hot and back again, ice dams are likely to form. They will then block the melted snow from running off of the roof and draining properly. The best way to deal with this issue is to up the insulation in your attic.

Now that you know the signs that a roof is in trouble, you have the insight necessary to be proactive in protecting your investment. Call the reliable and trusted team at GreenPoint Roofing as soon as you see any of the roofing trouble signs above, and we will provide immediate expertise.

New Roof Basics

roofer GreenPoint Roofing DenverAt GreenPoint Roofing in Longmont, Colorado, we offer these new roof basics to review if that is your big home project this year. Our expertise in roofing is an asset as you look for solutions to your home’s roof problems. A new roof is a good investment as it will protect your home better and keep your property value higher. Read on to learn about new roof basics.

Safety First Inspection

Before you head up the ladder, first take a look at the roof from the ground. Binoculars are a useful tool for this. If you notice curled shingles, missing shingles, or cracked shingles, these are indicators that your roof needs either repair or replacement.

Check flashing around roof valleys, skylights, and the chimney. Check for cracked rubber boots about vents. Obviously, a trained professional can inspect a roof more safely and efficiently, so never hesitate to call on your local roofing company, one that you trust, to provide a thorough inspection.

Leaks and Roof Damage

A leaking roof must be dealt with by a professional due to the complexity of repairs. Sometimes a leak can originate somewhere entirely out of sight but show up elsewhere. For this reason, a trained and experienced roofing contractor will be the resource to talk to about leaks and roof damage.

Two Too Many

Building codes require a tear-off and roof replacement if there are already two layers of roofing on your home. Starting over with a new roof is the best way to go as opposed to trying to remedy an already damaged, leaking or challenged roof. The weight of adding more layers of roofing can also damage the structure of the home and put everyone at risk inside.

Rot, Water Damage, and Infestation

Have your contractor check for any signs of decay, rot, water damage or insect infestation while inspecting the roof. Water and termites can wreak havoc on a home, so be aware of these hazards. Even though it may cost more to replace, putting a new roof on a rotting or compromised structure will cost much more later on, as you could lose the structure and roof altogether.

Removing the Old

Remember that with a new roof installation comes a new underlayment. This creates a moisture barrier which is essential for a long-lasting, efficient roof. This will be considered in your new roof estimate.

Estimate Roof Cost

To do a little calculation yourself before calling in the experts, try this roof cost estimation. Multiply the length by the width of the roof in feet to get the area; add 10% for error and inevitable waste. Divide this by 100 to determine how many squares of roofing you will need. Suppliers sell their roofing by the square. A typical 2300-square foot home needs about 30 squares. Add anywhere from $3000-$10,000 for labor costs, and you will have a general estimate for a new roof. It’s recommended to keep some extra shingles on hand for minor repairs after a storm.


Get a warranty for the materials and a separate workmanship warranty for a new roof installation. Save all of your documents, receipts, contracts, and warranty information on hand in case you need it later. A warranty on materials will cover the replacement of defective materials and can offer reimbursement within a period of time such as 10 years. Warranties do not cover wind damage over 85 mph.

Fire Rating

Be sure that your new roofing materials are fire rated Class A. you can always ask your Longmont roofing contractor about the fire rating when discussing other new roof basics prior to install.

Going Solar

If you are on the way to going solar and using solar energy to supplement your home’s electricity, then do the installation at the same time as the new roof. Because solar panels are weighty, your new roof will need to support that weight efficiently. That way, the new roof system can be designed correctly for solar power, right from the start and save you any do-overs later on. A structural engineer can he hired coinciding with your roofing contractor making sure everything is compatible and structurally sound.

Roofing Options

Part of the new roof basics is deciding what type of roofing material is going to work best for your situation. Your budget and home style will determine the materials choice. There is a wide range to choose from, so consider the long-term investment of your decision carefully.

Metal Roof

Metal roofs are easy to install and come in a variety of materials including aluminum, steel, alloys, and copper. Copper is the most expensive as it ages with a patina over time. This is aesthetically pleasing for many people, so again, it depends on the style of your home and your budget. Other metal roof options are much more affordable. Some tend to dent easily, but various textured surfaces hide minor damage exceptionally well. Along with being a bit noisier in a rainstorm, metal roofs do have a number of pros and cons to discuss with your Longmont roofing company before making a decision.

Asphalt Roof

When it comes to new roof basics, asphalt roofing is the most affordable option for a new roof and offers a relatively long roof life. An asphalt roof may last 30 years without needing major repairs. Of course, that depends heavily on what the weather conditions are and how severe the storms get – sun, wind, rain, hail and snow all play a role in roof deterioration.

You have two choices when it comes to asphalt shingles. Three-tab asphalt shingles are standard. Made of a single layer, they are low-profile and lay flat. Laminated shingles, called architectural or dimensional shingles, are layered and appear more like slate or wood shakes. It all depends on your style. 

Fake Slate

Made of composite materials such as rubber, asphalt, clay, plastic/polymer, faux slate roofing provides the same look as a real slate roof but without the bigger price tag. They also weigh less than real slate which is a bonus. However, know that fake slate is still susceptible to cracking or fading.

Now that you have a better idea about new roof basics, it’s time to take action and call your trusted roofing team at GreenPoint Roofing in Longmont. We are ready to help you tackle a new roof with competent and experienced craftsmanship.

5 Obvious Signs You Need Roof Replacement

Signs You Need Roof ReplacementBecause your roof protects everyone and everything below it from the elements, it’s vital to know the obvious signs you need roof replacement. 

While you can always call GreenPoint Roofing for an inspection, there are quite a few indicators of a damaged roof that you can look for on your own. 

Getting to know these signs yourself means that you can be aware of the condition of your roof and make an informed decision when it comes time to repair or replace it. 

#1 Your Roof is No Longer Doing Its Job

A leaking roof is one of the most obvious signs you need roof replacement. While a cascading waterfall in your living room will certainly make this issue obvious, it typically starts off much more subtle, and the damage slowly progresses.

Keep an eye out for wet spots, stains or puddling on ceilings. After rainstorms, check all rooms, even your attic for signs of water penetration.

#2 Your Roof is Really, Really Old

As a general rule, typical home roofs will last between 20 and 25 years before they require replacement.

When buying a house, it is wise to request information on the age of the roof as well as the age of the entire building. Once you know the approximate age of your roof, you can estimate how many more years it should last.

Factors such as the climate you live in and the general upkeep you give your home can add or subtract years from this general figure.

#3 You’ve Got Problems in Your Attic

Regular visual inspections from the inside can give homeowners a good idea of the condition of their roof.

From the inside of your attic, you can check for areas of sagging roof deck or water damage. Examine the inside of the roof for mold growth, dark spots, or trails. This discoloration could be evidence of water damage, especially if it occurs near the seams and joints of the roof.  

Check during the day to see if sunlight enters through unsealed gaps in your roof. If sunlight can enter, that means rain, snow and cold air can also make its way into your home. It’s certainly one of the more obvious signs you need roof replacement.

#4 Your Roof Has Bald Spots & Damage

From the outside, you should be regularly checking your gutters for loose asphalt granules. Older shingles can start to lose their structural integrity, and one of the first signs of this is loose granules.

Without walking on the roof or putting yourself in a dangerous position, visually inspect the shingles of your roof. If you notice more than a couple are missing, or that they are starting to curl upwards at the edges, this could indicate they are nearing the end of their functional lifespan.

Other key issues to look out for include broken or damaged metal flashing, extensive mold coverage, drainage problems and a high percentage of cracked shingles.

#5 A Professional Inspection Reveals Big Problems

If you notice any of the warning mentioned above signs you need roof replacement, you should get in touch with a qualified and licensed roofing contractor. Some specialists such as GreenPoint Roofing will even carry out an inspection free of charge.

If your roof does need a complete replacement, it is best to get this done during the warmer months of the year. Temperatures below freezing make shingles brittle, difficult to work with and the roof will not seal as effectively. Avoid a hasty and difficult roof replacement by regularly examining your roof and knowing well in advance if it needs replacement.

Tear-Off or Re-Shingle When Replacing Your Roof

Tear-Off or Re-Shingle When Replacing Your Roof GreenPoint Roofing DenverNeed to decide whether to tear-off or re-shingle when replacing your roof? The GreenPoint Roofing experts in Longmont, Colorado are here to help. We know it can be a big decision to make, and there are benefits and drawbacks to each. Today, we provide our valuable insight to assist you in deciding what is best for your unique situation.

In order to completely understand the decision as to whether to tear-off or re-shingle when replacing your roof, here are some definitions to clear things up. A roof tear-off is a complete replacement of the roof resulting in a brand new roof. Whereas, a roof re-shingle will add a layer to the existing roof without tearing off much at all.

Re-Shingle Pros

The two main pros of a re-shingle are that it is less expensive and less time is needed to get the job completed. It’s less costly because there are fewer labor costs involved with time focused on adding to the existing roof instead of removing and starting from square one. Avoiding completely tearing off the existing roof simply saves a lot of time. Additionally, it is less expensive because the materials needed to complete the job are fewer.

Re-Shingle Cons

However, there are quite a few cons to choosing a roof re-shingle as opposed to a roof tear-off. Let’s take a look at the downsides.


By merely adding a new layer of shingles to an existing roof, excess heat will inevitably get trapped inside creating two negatives situations. One, your home will heat up faster during our warm Colorado summers and two, the shingles will deteriorate quicker, even curling and possibly lifting up.

Hidden Damage

By only applying a new layer of shingles to the existing roof, any damage such as rotten wood will be hidden from view and hence continue to rot away, leading to more problems. Additionally, leaks will be harder to track within so many layers of roofing.

Eventual Re-Do

A re-shingle job is more of a temporary fix than a new roof installation. Even though new materials are used in a re-shingle, they will not hold up as well when installed over an existing layer. So, the inevitability of needing to replace the roof is high and remember a re-shingle can only be done once. More than one layer of shingles will cause damage to the structure and should never be attempted.


Because shingles are designed to be laid down on a new roof only, they will simply not hold up as well while using for a re-shingle as opposed to new roof build. They will tend to curl and lift up, furthering the risks of leaks and damage.


The mere weight of a re-shingle can pose a problem for the existing structure, especially if it is older or compromised in some way. Because you are adding practically an entirely new roof, in terms of the weight, you and your contractor must ensure that the re-shingling will not negatively affect the home or cause damage. A roof inspection might be a good investment before you move forward.

Lower Re-Sale Value

Obviously, a new roof is more valuable than a re-shingled roof. There may still be problems lying below a re-shingled roof that a re-roof would have taken care of. Hence, if you are planning to put your home up for sale, it is preferable to re-roof than re-shingle. Prospective home buyers will want to know that the roof is in good condition before they buy.


And lastly, aesthetics play a part in the downside of a re-shingle job. Because existing elements of the roof will still be visible including flashing and trim, re-shingling will not appear as finely finished as an entirely new roof will. You may still be able to see lumber and elements of the old roof. These may distract from the overall picture of the house. It’s merely another aspect to consider when deciding. whether to tear-off or re-shingle when replacing your roof.

Tear-Off Pros

There are quite a few positives for choosing a tear-off and new roof as opposed to a mere re-shingle. Here we lay them out for you.

High Quality

Because you will be starting from scratch on the roof, it will have every element of quality right from the start. The roofing materials, including lumber, shingles, and flashing will be brand new and installed correctly. This will prevent leaks and will withstand years of pressure from the elements.

Zero Problems

A re-roof from a qualified and experienced professional will be free of any issues. You are getting a brand new roof. So, it will last many, many years compared to a re-shingle which is more of a temporary fix.


When deciding whether to tear-off or re-shingle when replacing your roof, remember that a new roof will last a much longer than simply overlaying with new shingles. That means that you will not have to worry about your roof or address roofing issues for years to come.

Higher Re-Sale Value

Without a doubt, a new roof will fetch a higher price tag than a mere re-shingle can. A re-roof gets rid of all issues previously present, whereas a re-shingle only somewhat covers problems up temporarily. Prospective buys will like the sound of a new roof being part of the purchase price instead of knowing that they will have to install a new roof themselves after a few years with the re-shingled one.

Tear-Off Cons

The only real cons to choosing a re-roof are the expense and the time involved. It costs more due to the labor involved and the possible need to stay elsewhere during the process. The roofers must remove all of the roofing structure in order to install the new one. Also, it takes more time to put on a new roof, than simply adding shingles to an old one.

The team at GreenPoint Roofing is here to help you determine if a tear-off or re-shingle when replacing your roof is the best option. Our dedication to quality will be an asset to you, and our service-minded approach will ensure quality results ensue no matter the size of the roofing project.
