Your Wild Winter Roof Check-Up Guide

Your Wild Winter Roof Check-Up GuideIt has certainly been a nasty winter here in Colorado with plenty of snow and even a bomb-cyclone. Taking the brunt of things has been your roof.

So, if you want to avoid a nasty surprise like water coming through your roof and into your home, use this roof check-up guide to determine if your roof needs to be repaired or even replaced.

GreenPoint Roofing has over 20 years of experience in the roofing industry here in Colorado. Our team has put together this list of sure signs that your roof needs some attention. Tackling an issue with your roof is easier and more affordable if you do it early. The following roof symptoms are easy-to-spot visual signs that any homeowner can check for themselves.

  1. Splitting or Cracked Shingles

Number one in our roof check-up guide is examining your shingles. When exposed to weathering or dramatic temperature changes, shingles can suffer from 'thermal splitting.' Over time the surface of the shingle shrinks, but if the side exposed to weathering shrinks at a different rate to the inner side of the shingle, you may see lines on the shingles were the asphalt coating has cracked. This splitting or cracking can happen in any direction or a vein pattern.

  1. Sagging or Bowing Roof

A visibly sagging roofline indicates a severe structural problem with your roof. Sometimes a bowing roof is not visible from outside, but you may notice cracks in your ceiling drywall. This can indicate that the rafters or roof sheathing are not fully supporting the weight of the roof.

  1. Creasing Shingles

Creasing shingles happens when there are gaps that allow winds to get under the shingles and bend them upwards, creating protruding creases along the shingle. If the shingles are improperly installed, or if the underside has protruding nails, it's possible that the sealant will not fully adhere the shingles, leaving them vulnerable to gaps and creasing.

  1. Separating and Broken Seals

You may notice shingles that have lifted and are separated from their adhesive strips or seals. High winds or loose nails can allow shingles to break away from the sealant between each layer. This compromises the structure’s waterproofing abilities and the roof should be repaired without delay. Don't ignore this issue from our roof check-up guide.

  1. Cupping Shingles

Cupping shingles are usually caused by exposure and weathering over time, or by ice dams. The surface of the shingle warps, leaving a concave center with raised edges forming a cup shape. Cupping shingles make your entire roof look shabby, and they can be fragile and prone to breakage.

  1. Ceiling Water Spots

Water stains on your ceiling are a clear sign that your roof is failing at protecting the interior of your home from the elements. At this point, you don't even need our roof check-up guide. You just need to take action. Leaks in your roof can quickly lead to mold and rotting interiors. Check your attic or crawlspace for the source of the leak and use a container to collect any dripping water while you wait for a roofing professional to fix the problem.

  1. Buckling Shingles

Buckling shingles do not lay flat on your roof as designed. They warp or buckle outwards, usually as a result of the roofing underlayment wrinkling or moving around. They can also buckle due to poor ventilation and trapped moisture. When shingles do not lay flat, they allow more moisture and winds to enter the spaces, worsening the problem and damaging the underside of the roof.

  1. Damaged Flashing

Flashing is the watertight layer of metal protecting the base of chimneys or other protruding objects where they meet the roof's shingles. If you notice broken, uneven, curling or shifted flashing, your roof will be vulnerable to water entry and damage over time.

  1. Rotting Shingles

Rotten shingles are a sign of advanced damage to your roof. If your shingles are breaking apart, flexible and moist to the touch or easily disintegrate when manipulated, act quickly to get your roof replaced. This often occurs in organic-based shingles which are no longer on the market.

  1. Missing Granules

Roofing shingles are covered in granules to help protect the asphalt coating from the damage associated with UV rays and to make them fire resistant. If you notice that your shingles are balding or missing granules from their surface, you can expect rapid deterioration. When inspecting the roof, check in the gutters for an accumulation of shingle granules.

  1. Blistering Shingles

Shingles can blister when there isn't sufficient ventilation or insulation. Trapped moisture in the shingle expands the outer asphalt and leaves behind a pockmarked area. Blistering shingles typically happens within a year of the roof's installation and can lead to significant loss of asphalt if not addressed.

  1. Algae, Moss, and Lichen

Dark streaks of algae, green moss, or white spots of lichen are living organisms that can thrive on damp roofs. Shaded roofs in humid climates are more susceptible to damage from living organisms. While they do not usually cause more than superficial damage, they can ruin the appearance of a roof and should be cleaned or removed by a professional to prevent further damage.

  1. Missing Shingles

Heavy storms can sometimes leave your roof with a few missing shingles. We've included this in our roof check-up guide because you'll need to get them replaced as soon as possible to prevent water from reaching the underside of the roof and causing permanent damage. If your roof has a lot of missing shingles, it may be time for a complete roof replacement.

  1. Curling, Brittle Shingles

Curling shingles are typically found in older or worn roofs. They are a sign that the roof is approaching the end of its lifetime. When you see shingles curling upwards and away from the surface of the roof, they are no longer providing the necessary protection. Leaks and water damage beneath the shingles can quickly follow.

If you notice any of the symptoms included in our roof check-up guide, do not ignore them. While they may seem like minor or cosmetic issues, they are often a clear sign that your roof is no longer serving its purpose. When your roof cannot adequately protect your home, you are putting at risk the very structure of the house, along with your possessions and the people living inside.

GreenPoint Roofing offers professional inspections to analyze roofing damage. If deemed necessary, we can repair or entirely replace your roof. We offer a lifetime workmanship guarantee on all shingled roof replacements. In addition to our roofing contractor services, we can also assist you in making a claim on your home insurance for damages covered by your policy.

Why Does Roof Replacement Cost So Much?

Why Does Roof Replacement Cost So Much?A roof is a very big expense. However, once you understand the process, it's easy to see why your roof replacement cost is higher than other work you might have done on your home, as well as how much value you're getting for your investment.

At GreenPoint Roofing, our team of licensed and insured roofers brings years of experience and professionalism to every job. It is essential that you only have the most skilled and trustworthy contractors to provide a roof replacement. That means you should rarely if ever, go with the bottom of the barrel bid on your roof replacement. 

In addition, 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 just how much work is required and how that corresponds with pricing.

Removal of Materials

First things first, your roof replacement cost includes removing 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.


Here's where your roof replacement cost may vary based on what you choose. 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

Y our roof replacement cost includes drip edges that 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!


Here's another area where your choice of materials can affect your roof replacement cost. 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 your general roof replacement cost 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!

At GreenPoint Roofing, we know the ins and outs of roof replacement and will follow the procedures to the utmost so that you get the most out of your new roof replacement in Colorado. Call us today to inquire about roof replacement for your home or other structure in need.

How Can You Tell If You're Hiring The Right Roofing Company For Your Project?

hiring the right roofing companyDid you realize that 10 percent of American homeowners feel as if they are falling behind when it comes to maintaining their residence? The longer a home goes without the proper upkeep, the higher the risk becomes of serious repair issues developing.

One of the most important parts of any home is the roof. It keeps everyone and everything below it safe.

The roof of your home is exposed to direct sunlight for hours each day. Over time, this exposure can dry out your shingles and cause them to malfunction. When faced with repairs or the possibility of replacement, hiring the right roofing company is essential.

Are you looking for a roofing company to help you get this critical structure back in good working order? If so, read below to find out how to hire an experienced and professional roofing company for the job.

Pay Attention to Communication When Hiring the Right Roofing Company

If you are like most homeowners, you know very little about how your roof actually works. Instead of letting this lack of knowledge stand in the way of a damage-free roof, you need to work with a reputable roofing contractor. Before hiring a roofing company, be sure to pay attention to their ability to communicate.

During the initial consultation, let them know what you need. As you tell them about what’s going with your roof and what you need help with, pay attention to whether or not they are actually listening to you. The best roofing experts will work hard to ensure the needs of their customers have been met.

If it feels like a contractor is only paying attention to what they are going to say next, you should probably avoid hiring them. Ideally, you should hire a company that values communication and keeps you in the loop during the repair or replacement process.

Patience is a Great Virtue for a Roofing Contractor to Have

Finding and fixing the issues a home’s roof has can be quite complicated. During the diagnostic process, a roofing contractor will have to make a number of decisions. If they do not have the patience to work through each step and address challenges that come up, it can lead to roofing repairs not getting done properly.

When interviewing potential roofing contractor hires, ask them the strategy they use on each project. Reputable and experienced contractors will plan out the jobs they work on in meticulous detail. This level of planning allows them to get the work done quickly and correctly so you know you’re hiring the right roofing company.

Selecting a Trustworthy Roofing Repair Company

Horror stories about less than reputable roofing companies ripping homeowners off are all too common. While you may be apprehensive to hire professionals to fix your roofing problems, it is essential when trying to avoid further issues. Instead of trying to do this work on your own, the main goal you should have is hiring the right roofing company.

Before hiring a contractor, be sure to find out about how long they plan on the job taking. If your entire roof needs to be replaced, you must to hire a company that will work consistently from start to finish. Since replacing a roof will leave the inside of your home exposed to the elements, time is definitely of the essence.

The best roofing contractors will only make promises they can keep. If a particular company makes and breaks promises in the time leading up to the project starting, you should replace them before it is too late. Paying a bit more to a trustworthy roofing company will be worth it in the long run.

Organization is the Cornerstone of a Successful Roofing Job

There are a number of moving parts involved in addressing roof damage, even more when it comes to roof replacement. Most roofing companies will have a crew of workers they use to complete these jobs. Working with a roofing contractor that is organized can make this process more manageable for everyone involved.

The first thing an organized roofing company will provide you with is an accurate and itemized estimate. This includes a breakdown of the materials needed to fix or fully replace your roof. Often times, itemized estimates will also detail the cost of materials and labor. It may or may not include a contingency for surprises that come up along the way, so be sure to ask your roofer how unexpected expenses will be handled.

Once you receive this estimate, you need to make sure the roofing contractor in question doesn’t throw any surprise charges. By getting everything in writing, you will have recourse if you get hit with a big bill.

Find Out Who Will Be Performing the Actual Repairs

One of the biggest mistakes homeowners can make is not verifying that the company they hired will handle all of the work. There are a number of roofing companies that sub-contract work out to other businesses. If this will be happening, you need to know this information before hiring a company.

The only problem with hiring a company that sub-contracts out work is that you never know how well the other business will perform. If at all possible, hiring the right roofing company means making sure their team handles every aspect of the project.

Getting a Good Deal is Vital

For most homeowners, operating on a budget is important. When home repairs arise, finding a company that can get the work done for a reasonable price is crucial.

By scheduling an onsite estimate, you can easily see which roofing contractor provides the best deal – without coming in with an outrageously low bid. Be wary of those guys.

While you shouldn’t make this important decision on price alone, getting a good deal on these repairs should be high on your list of priorities. With a bit of time and research, finding the best roofing contractor will be a breeze.

Avoid Rushing Through the Selection Process

The main thing you should avoid when trying to find a roofing contractor is rushing through the research process. When hiring the right roofing company, you need to be prepared to take your time. Check certifications, references and their portfolio.

How to Assess Your Commercial Roof for Repair or Replacement

assess your commercial roof GreenPoint Roofing DenverMost roofing products come with a general timeline regarding when you will need to replace your commercial roof.

While most should give you 20-30 years of protection from the elements, exposure to harsh weather conditions (like hail) and insufficient maintenance may lead to needing roof repair or replacement sooner than expected.

If you suspect it’s time for a new roof, contact GreenPoint Roofing. Based in Longmont, we’re a locally owned company specializing in roof repair and replacement across Colorado.

Today, we’ll cover how to assess your commercial roof to determine what work needs to be done to provide your business with proper protection from the elements.

Have an Expert Assess Your Commercial Roof

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 assess your commercial roof for leaks, premature aging and overall deterioration.

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.

Replacing vs. Repairing Your Commercial Roof

Once you have the level of damage determined by a professional, you’ll be another step closer to deciding if it’s 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 structure is older than 20-30 years with an original roof, 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 won’t last very long.

When you assess your commercial roof, the results may also reveal that improper materials were used to construct the roof or specific industry standards weren’t met. This might be due to corners being cut during the original build or simply reflect the age of the building. If this is the case, it’s advisable to opt for a full replacement that meets current codes.

In addition, a commercial roof that has damages over more than 25% of its area will require replacement. The cost of maintenance on an extensively damaged roof can easily overtake the cost of investing in a brand new roof in just a few years.

When 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 may be feasible.

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 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, especially after heavy rain. If you suspect a problem feel free to contact our experts at GreenPoint Roofing. We will assess your commercial roof, as well as provide a competitively priced estimate for any work needed.

Can You Replace Your Roof in Winter?

Replace Your Roof in Winter by GreenPoint Roofing DenverDuring warm, dry summer months in the Denver area, many homeowners may think that their roof is in perfect shape. Then fall arrives, bringing snow and rain, and suddenly there’s a leak or shingles that have frozen and begun cracking.

Now what? Can you even replace your roof in winter?

Absolutely. At GreenPoint Roofing, we know that homeowners will choose to get an old roof replaced during the summer, but if necessity requires, the same job can be completed during the winter. In fact, it actually comes with some advantages.

Let’s take a closer look at what happens when you need to replace your roof in winter.

Do Roofing Contractors Work During Winter?

Unlike bears, roofing contractors do not hibernate during the winter. We continue to work all year-round, attending to the customers that need our services.

As we said, it’s not unusual to realize that you have a leak or a problem with your roof until the winter hits. That’s when you’ll start to see moisture entering the home due to rain or snow.

Scheduling a roofing contractor during the winter can also be a lot easier than he summer when the demand is higher. Many roofing professionals even prefer to do specific projects during the winter when the temperatures are not suffocatingly hot.

Of course, if you need to replace your roof in winter, there are disadvantages such as having to reschedule in case of snowy weather, not to mention relatively shorter days. Some roofing jobs are a bit tougher during the winter, so it is a good idea to discuss scheduling and contingencies.

Replacing Your Asphalt Roof

One of the more challenging winter roof replacements are asphalt shingles which can become brittle and difficult to work with during freezing temperatures. In addition, the adhesive that provides a seal between overlapping shingles will not bond sufficiently without the sun’s heat.

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. Ideally, asphalt shingles should only be installed when temps are between 40 and 85 degrees.

Flat and Metal Commercial 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.

If you want to replace your roof in winter, you may run into trouble if you want a flat rubber roof. These 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.

Last but not least, metal roofs are the least affected by cold temperatures, so they can be easily installed during winter.

For help, please contact GreenPoint Roofing in Longmont. We offer in-home consultations and free estimates if you need to replace your roof in winter. We pride ourselves on working with honesty and integrity. Our priority is to provide high quality, long-lasting roofing at the best possible price for both homeowners and businesses.
