5 Questions to Ask Your Commercial Roofing Contractor

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

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

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

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

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

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

2. Request Referrals and Check Reviews

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

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

3. Get to Know their Commercial Roof Offerings

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

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

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

4. Make Sure They Can Accommodate Your Needs

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

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

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

5. Clarify Guarantees and Warranties Before Moving Forward

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

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

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

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

5 Obvious Signs You Need Roof Replacement

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

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

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

#1 Your Roof is No Longer Doing Its Job

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

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

#2 Your Roof is Really, Really Old

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

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

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

#3 You've Got Problems in Your Attic

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

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

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

#4 Your Roof Has Bald Spots & Damage

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

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

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

#5 A Professional Inspection Reveals Big Problems

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

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

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.
