Residential Roof Replacement Step-by-Step
At 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.
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
When 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 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 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
As 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
Doing 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?
Wondering 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.
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.
During a roof inspection, your or your roofing professional should look for any signs of:
- Water damage
- Dark spots or discoloration
- Light shining through from outside
A roofing inspection also includes looking for any signs of moisture penetration:
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
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.
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.
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.
