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.

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.

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.

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.
