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.

The Basics of Roof Replacement

Basics of Roof Replacement GreenPoint Roofing DenverGet the facts you need with these basics of roof replacement from GreenPoint Roofing. Our team of licensed and insured roofing contractors can help you with what to look for and how to proceed when it’s time for a new roof on your structure in Colorado. It is essential only to have the most experienced and trustworthy contractors provide the roof replacement.

There is a specific process to follow. Any skipping of steps will lead to a mediocre roof replacement job and less than perfect results. With a roof replacement, you want to know that your roofing contractor knows what they are doing, are performing all of the right steps, and is providing the quality workmanship you deserve.

Here is a simple overview of what goes into a roof replacement project so that you know the basics of roof replacement when it comes time for your own.

Removal of Materials

First things first, we must remove all of the layers that have been placed on the roof over the years. Many times, instead of replacing the roof entirely, a homeowner will choose to add roofing layers. Hence, 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 of the way down to the wood roof.

Replace 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.


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.

Ice and Water Shield

One of the basics of roof replacement, this shield 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.


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

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. It is crucial that no tabs or bonds overlap here.

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 installed correctly, as they will save your roof from irreparable damage down the road.

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 re-roofing project!

Flashing and 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.

Pipe Boots

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


Keep water diverted and correctly 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 installed, for the longevity of your roofing!


With the right, high-quality shingles, you won’t need to schedule shingle replacement for quite a while. While the cost of shingles varies, one of the basics of roof replacement is that it’s all about quality. 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!

Gutter Guards

As long as you can afford the quality option, install gutter guards to keep debris out of gutters. Some gutter guards will only last about one 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.

Knowing the basics of roof replacement will help you make the best decision when it comes time to choose a roofing contractor. There is no reason to settle for less than the best!

About Winter Roof Replacement

About Winter Roof Replacement GreenPoint Roofing DenverToday at GreenPoint Roofing, we want to talk about winter roof replacement in Denver and throughout Colorado. While many homeowners will opt to get their roof replaced during the summer months, it is certainly possible to have the same job completed during the winter. In fact, a winter roof repair or replacement actually comes with some advantages. Let’s take a closer look at what you need to know about winter roof replacement.

Do Roofing Contractors Work During Winter?

Unlike bears, roofing contractors do not hibernate during the winter. We continue to work year-round, attending to the customers that need our services. Often, homeowners don’t even realize they have a leak or a problem with their roof until the winter hits. That’s when they can start to see moisture entering the home due to the slow melting snow. Scheduling a roofing contractor during the winter can be a lot easier than during the summer when the demand is higher.

Many roofing professionals prefer to do specific jobs during the winter when the temperatures are not suffocatingly hot. Remember, in 90-degree weather, the top of your roof is about 120 degrees. There are some disadvantages to winter roof replacement or repair, such as the extra time needed to clear snow if it has built up, and the relatively shorter days. Some roofing jobs are tougher during the winter, so it is a good idea to discuss scheduling them later in the year.

Asphalt Roofs

One of the more challenging winter roof replacements are asphalt shingles which can become more brittle and difficult to work with during freezing temperatures. In addition to this issue, the adhesive that provides a seal between overlapping shingles will not bond sufficiently without intense heat from the sun. To avoid having these shingles coming loose or blowing off your roof shortly after having them installed, it’s best to keep a close eye on the weather. We tend to have warmer days even in winter, so an asphalt roof replacement isn’t out of the realm of possibility.

Flat and Metal Roofs

For flat roofs, typically commercial roofing, the best type of materials to install during the winter are PVC and TPO (Thermoplastic Olefin). These single ply materials do not require the heat of the sun to bond successfully. They are sealed manually by a roofing professional using a hot air welding technique. Flat rubber roofs are a challenge to install during the winter months as the adhesives used to fix them to the underlayment may not bond and can result in leaks. Metal roofs are the least affected by cold temperatures, so they can be easily installed during winter.

If in doubt about winter roof replacement, do not hesitate to contact GreenPoint Roofing in Longmont. We offer in-home consultations and free roofing estimates to all of our new and returning customers. We pride ourselves on working with honesty and integrity. If there is a roofing job better done in the summer, we will let you know. Our priority is to provide high quality, long-lasting roofing at the best possible price for both homeowners and businesses.

Is It Time to Replace Your Commercial Roof?

Is it time to replace your commercial roof? GreenPoint Roofing DenverIs it time to replace your commercial roof? GreenPoint Roofing, a locally owned company based in Longmont, installs and replaces roofs all across Colorado. We are your go-to experts for commercial roof assessment and repair. While most commercial roofs should give you 20-30 years of protection from the elements, exposure to harsh weather conditions and insufficient maintenance may lead to a roof replacement sooner than expected.

Request an Inspection

If you suspect that your commercial roof is not performing as it should, the best action to take is to arrange a roof inspection by a professional. A qualified roofing contractor will be able to detect leaks, premature aging and overall deterioration of the roof. An inspection should include an internal and external examination of all seams, flashing, and joints. Any evidence of damage such as rot, cracks, loose flashing, or punctures can be recorded in a report and a suitable solution recommended.

Replace or Repair?

Once you have the level of damage assessed by a professional, you’ll be another step closer to determining is it time to replace your commercial roof. The first factor you should take into account when making this decision is the age of your roof. If your roof is older than 20-30 years, a repair will only temporarily delay the inevitable. It is better to invest in a complete commercial roof replacement in this case, rather than spending money on a fix that will not last very long.

If the results of your inspection reveal that unsuitable materials have been used to construct the roof, it is advisable to opt for a full replacement. There are specific standards to be upheld in the construction of commercial roofs, and particular materials required, especially for flat roofs. If corners were cut in the original construction, to save time or money, your roof might have to be replaced. A commercial roof that has damages over more than 25% of its area will require replacement. The cost of constant maintenance on an extensively damaged roof will overtake the cost of investing in a brand new roof in just a few years.

If the damage to your commercial roof is contained to a small area, and the rest of the roof is in good condition, a targeted repair or a partial replacement to that area can be the best solution. If your budget will not stretch to a full replacement of a damaged roof, you could carry out the replacement in sections over an extended period. It is a good idea to prioritize the areas where a fully functional roof it is imperative, like over office space or expensive machinery.

For building owners, it is essential to keep track of roof maintenance and record any issues that arise. Remember to check ceilings for leaks or damp spots regularly, and especially after heavy rainfall. If you wonder, is it time to replace your commercial roof, feel free to contact our experts at GreenPoint Roofing. We are ready to provide professional solutions for commercial roofs across Denver and Colorado.

Why Fall is a Great Time to Replace a Roof

Why Fall is a Great Time to Replace a Roof GreenPoint Roofing DenverDo you know why fall is a great time to replace a roof? At GreenPoint Roofing in Longmont, we strive to keep clients informed with useful information on home roofing. Now that September is coming to a close, it’s time to think about vital home maintenance that should be completed before winter arrives. If you suspect that you need a new roof, but have been putting off calling in a professional, now is the best time to get it done.

The main reason why fall is a great time to replace a roof in Colorado is the mild weather. If you wait until winter to replace your roof, you risk exposing your home to freezing temperatures, snow, and chilly winds. This is not only unlivable for you and your family, but it also slows down our crew. Cold temperatures cause asphalt shingles to become brittle and more likely to break as they are nailed into place. In order for the shingles to adhere properly, they must undergo thermal sealing, which requires an ambient temperature of at least 50°F.

If you decide to wait until next year to replace your roof and make it through winter without a leak, you may be caught off guard by some of our rather unpredictable spring and even summer weather conditions. As you know, our Colorado hail can wreak havoc on your home renovation plans and even expand your workload with new damage that needs to be repaired. 

After hail comes extremely high temperatures which can be difficult for the roof replacement crew to work in. For the highest probability of an efficient and successful roof replacement, there is no better time than a clear fall day, before the daylight hours shorten too much. 

Getting your roof replaced before the winter season means that you are much less likely to suffer from typical cold weather damage. Roofs with minor holes, missing tiles or broken seals may not actually reveal the extent of their damage until winter hits. Ice dams, meltwater and the weight of snow build-up can put excessive strain on a weakened roof and lead to severe damage. Replacing your roof just before winter will ensure it is ready for the harsh weather. 

When replacing your roof, it is a good idea to make sure you are as energy efficient as possible. Have your roofing contractor check your attic insulation and the inner seals of your roof. Modern materials can be used on the sheathing and underlayment layer of your roof to prevent heat transfer and help lower your overall energy bills. A modern, energy efficient roof will make your home more comfortable year-round and increase its value.

These are just a few reasons why fall is a great time to replace a roof. Don’t risk leaving it until next year. Schedule your roof replacement with GreenPoint Roofing now for immediate peace of mind.

Choosing a Material for Your New Roof

Choosing a Material for Your New Roof GreenPoint Roofing DenverWhen it comes to choosing a material for your new roof, GreenPoint Roofing advises our customers to consider all aspects. In addition to the obvious factor of cost, you also need to consider whether it is practical, aesthetically pleasing, durable, easy to maintain and if it fits in with the neighborhood style.

Each type has its advantages and disadvantages, so keep reading to find out what to consider when choosing a material for your new roof.


Asphalt shingles are the most commonly used as roofing material in the United States. This is due to their ease of installation and their low cost. An asphalt shingle roof is composed of a fiberglass layer and an asphalt granule layer to ensure waterproofing. Asphalt shingles can be expected to last around 25 years and can be repaired and replaced easily by most professional roofers.


Slate roofing tiles are extremely durable, and will usually outlast the fasteners that hold it in place. You can expect slate roofing material to last a hundred years or more. With this longevity comes a high price tag. A slate roof can cost far more than an equal-sized asphalt roof. Slate tiles are also extremely heavy so may require structural reinforcement of the roof before they can be laid. We can inspect your roof and provide an estimate if you want the long-lasting durability of slate.

Tile or Cement

Half-cylinder terracotta tiles are most often seen on the roofs of Spanish Colonial style homes. This roofing material is visually appealing and very durable, transforming your home or commercial property into a work of art. Replica tiles are sometimes made out of cement or metal. Similar to slate, these tiles or cement half-cylinders are bulky and the cost will need to be considered. But the look you’ll achieve may be well worth it.


Wood was the traditional choice in roofing material before the development of asphalt shingles and other advanced materials. Wooden shakes or shingles can be made from cedar, redwood and Southern pine, offering a variety of natural colors that look great on Craftsman style homes. A wood roof can be expected to last around 25 years, but it will usually cost much more than asphalt. Plus, some areas do not allow wood roofing due to the potential fire risk. We can advise you on your options.


Metal roofs can be installed as shingles or flat seamed surfaces. You can find metal shingles made from lead or a copper and asphalt compound, and seamed metal roofs are typically made of copper, steel or aluminum. This style of roof tends to be quite expensive, but durable and an excellent option for custom homes with a distinct look. Again, it’s an investment that can pay off in both looks and style.

Should You Replace Your Roof Before Selling Your Home?

Should You Replace Your Roof Before Selling Your Home?Here at GreenPoint Roofing of Longmont, Colorado, a frequent question we hear from customers is, should you replace your roof before selling your home? This week we want to address this issue and discuss the pros and cons of replacing your roof before putting your home on the market.

Most homeowners will make at least some effort to catch up on maintenance in their home and ensure it is looking its best before they attempt to sell it. Replacing the roof is a big job that requires some serious financial and time investment. Keep reading to find out should you replace your roof before selling your home?

Will a New Roof Really Make a Difference?

For homeowners trying to sell their house, a visibly old roof with noticeable damage such as missing or curling shingles, structural sagging, mold and mildew growth is an instant warning sign to potential buyers. The state of the roof leaves a strong visual impression on visitors to your home. Before they even enter, they can be turned off by the sight of a roof in disrepair and may even conclude that the entire home is unmaintained. Some buyers are open to the idea of taking on a property that needs a lot of work, but most will want to be able to move in immediately without putting a lot of extra money into renovations.

If you do invest in a brand-new roof before putting your house on the market, the overall impression made on those viewing the home will be much better. You will not be limiting the potential buying market to those ready to take on a massive refurbishment project. With a new roof, your home will be instantly more attractive, and you can easily set a higher asking price. A brand-new roof will greatly influence a professional evaluation of your home, and this can give the seller better-negotiating power when it comes to finalizing the price.

If I Choose to Replace the Roof

When deciding should you replace your roof before selling your home, there are a couple of things to take into consideration. First, think about the cost versus the payoff. Get some quotes for the roof replacement and make sure the job is within your budget. Then, compare the cost of the full roof replacement to the change in asking price of the home you can reasonably set once the roof has been replaced. If the extra amount of money you can make on selling your home after a roof replacement is greater than the cost of the roof replacement, then it does make financial sense to go ahead and replace your roof. Buyers will consider not only the monetary cost of the new roof but also the value of the time and organization put into the job and the inconvenience of having the roof replaced.

Just because you plan on selling the home does not mean you can cut corners when it comes to replacing your roof. Find a professional roofing contractor with an excellent reputation and plenty of experience. If in doubt, check their online reviews and ask whether they are accredited with the Better Business Bureau to get some idea of their reputation. Check to see if a workmanship guarantee is offered in addition to product warranties. This is another bargaining chip you can use when it comes to negotiating the final price with buyers.

Some homeowners might be tempted to re-roof a layer of new shingles over the existing shingles instead of completely tearing off and replacing the roof. This will be cheaper and less invasive to do, but it may not adequately increase the asking price of your home. A re-roofing job can be seen as rushed, or a lazy ‘quick-fix’ to hide problems without really addressing them. This will also be noted in any home inspection or evaluation done on your home and is generally not looked upon favorably by professionals. A complete roof replacement with neutral colored shingles or tiles will be the most effective in appealing to a wide market and increasing the value of your home.

If I Choose Not to Replace the Roof

When it comes to should you replace your roof before selling your home, homeowners who stick with the existing roof will undoubtedly save a bit of money. If your roof is relatively new and in decent condition, you may not have much to gain by replacing it. Again, you need to compare the cost of replacing the roof to the increase in selling price. If this increase is not greater than the cost of roof replacement, then it might make sense to leave it alone. It may also spare you from the stress of trying to move out of the home while the roof work is in progress.

Leaving your roof as-is allows you to get the house on the market faster. Although the roof replacement itself takes just a few days, it’s not ideal if you really need a quick sale. Houses without up to date maintenance are still being sold at a decent pace here in Longmont and the Denver area. If there are numerous homes up for sale in your neighborhood, you can set the price just below the average in the area to hopefully attract buyers. If you can attract multiple buyers, one may be willing to skip inspection and an extended negotiation, allowing you to sell the home even if the roof needs replacement.

So, should you replace your roof before selling your home? The answer to this question depends on the condition of your roof, the local housing market and how quickly you want to make the sale. Once you have weighed out the pros and cons of both options and worked out the financial benefit of replacing the roof, you should be able to make a decision that makes sense for your situation. GreenPoint Roofing in Longmont is currently offering a lifetime workmanship warranty on all shingled roof replacements.
