Commercial Roofing Coating Contractors

Commercial roof coatings are a protective layer applied to the surface of a roof to make it into a cooling agent for your entire building, helping save some “green.”

A white commercial roofing coating will sharply lower the temperature of a roof’s surface during the summer by reflecting UV rays instead of absorbing them, like a traditional black roof. You can keep your building cooler, reduce the load on your HVAC unit, and save bundles of cash by talking to us about roof coating systems.

Commercial Roofing Coatings for Single-Ply, Built-Up, and Metal Roofs

Coatings can extend your roof’s life, but only if your contractor takes the time to properly prepare that roof before the roof coating system is applied.

When choosing the right kind of coating, there are several key factors to consider to ensure optimal performance and longevity. This includes the roof’s condition and materials as well as weather conditions. GSM Roofing is ready to show you many types of coatings and help you make the best choice for your commercial building.

Here are the most popular types of coatings offered by our manufacturers:

Acrylic Roof Coatings

Acrylic roof sealants are cost-conscious choices that are water-based and simple to apply for an experienced roofing contractor like GSM Roofing. The result is a roof surface that reflects UV rays to save energy and extend the roof’s life.

This type of commercial roof coating does have a drawback, however. It is susceptible to thinning over time, mainly where ponding is present.

Polyurethane Roof Coatings

These solvent-based coatings are applied in two parts — a base layer and a UV-stable top coat. Its advantages include color retention, traffic and dirt resistance, and the ability to withstand moderate ponding.

As good as polyurethane roof coatings are, their fumes can be offensive, and their price points are higher than acrylic roof coatings.

Styrene Ethylene Butylene Styrene Coatings (SEBS)

SEBS solvent-based roof coatings deliver several advantages, including solid adherence to roof surfaces, UV-ray resistance, and superior handling of ponding.

This type of coating requires regular maintenance to keep the damaging properties of water and sunlight at bay.

Silicone Roof Coatings

Silicone could be called the superstar of all commercial roofing coatings. You can’t beat them when it comes to withstanding ponding, humidity, and the sun’s UV rays.

We have found that solvent-based silicone roof coatings tend to get dirty, but the rain rinses them reasonably well. And when it comes time to recoat the roof, keep in mind that a compatible silicone coating must be used — others will not adhere well.

Extend the Life of Your Roof

When you have a roof coating applied to a commercial roof, you can expect it to extend the life of that roof by up to 20 years. Here’s how:

Solar Reflectance Slows Down Roof Aging

The sun’s UV rays break down roofing materials, causing them to dry out, crack, leak, and cause water damage. But when a white coating reflects those rays, it protects the roof’s surface from brittleness.

Superior Flexibility Allows for Movement

Your entire building expands and contracts with seasonal and daily weather and temperature changes. An elastomeric reflective roof coating can stretch to nearly twice its size, so it won’t crack or tear.

Sloping Can be Used to Avoid Ponding

The white roof coatings we use are highly resistant to degradation in areas where water ponds. Plus, we can build up low spots and coat them so that water runs away from areas that tend to hold water.

Exceptional Adhesion Reduces Prep Time

Some of the white roof coatings we use require no etching or priming before application. That saves you labor costs and means that their superior adhesion will contribute to a longer roof life.

Are you ready for GSM Roofing to apply a coating that cools your roof and building, reflects damaging UV rays, protects against ponding, and sticks like nothing else? Get in touch with us to discuss the best roof coating for your commercial structure.

Cash Savings Isn’t the Only “Green” that Comes with Roof Coatings

Commercial roof coatings can help you put off roof replacement until it’s necessary. Plus, they’re considered “green” initiatives.

  • When you have a roof replaced, truckloads of old roofing materials get hauled to the landfill, where they’ll take centuries or more to degrade. But commercial roof sealants keep re-roofing debris out of landfills, and that’s a green initiative that’s hard to beat.
  • By reflecting UV rays, commercial roof coatings help preserve existing roof systems, cutting down on new manufacturing.
  • White roof coatings keep the sun’s UV rays from raising interior temperatures, reducing cooling energy consumption.

Our commercial roofing contractors can apply these eco-friendly coatings to single-ply, built-up, and metal roofing systems.

Roof Coating in Wilmington, DE

The Roxana Cannon Arsht Surgicenter required a specialized roofing solution that would allow surgeries to continue uninterrupted while minimizing the risk of fumes, dust, and noise interfering with sensitive instruments. Christiana Care Health System selected GSM to apply a Tremco AlphaGuard Coating — a low-odor system ideal for work during business hours.

To prepare the aging EPDM roof, GSM first scanned for moisture and damage, then completed necessary repairs. Power washing was done after hours to avoid vibrations during surgical procedures. The fast-curing, two-part coating system had to be applied in small sections within a tight 20-minute window, requiring a four-person crew to work efficiently. This approach ensured a high-quality restoration with minimal disruption to the center’s daily operations.

Roof Coatings FAQ

How can I Tell if My Commercial Roof Needs a Coating?

 If your roof is structurally sound but starting to show signs of wear, your commercial building may benefit from a coating. Common indicators include:

If your roof has major structural damage or saturated insulation, a coating may not be the right solution. The best way to know for sure is to schedule a professional roof inspection — our experts can determine whether coating will extend your roof’s life or if repairs/replacement are necessary.

What Determines How Long a Roof Coating Will Last?

The lifespan of a commercial roof coating depends on the type of coating used, the condition of the existing roof, the climate it’s in, and how well it’s maintained.

Will a Roof Coating Stop Leaks?

A roof coating can seal small cracks, seams, and pinhole leaks, helping prevent water from penetrating your roof. Many coatings are designed to create a seamless, waterproof membrane that protects against future leaks.

However, coatings are not a cure-all. If your roof has significant water damage, ponding issues, or large open leaks, those problems need to be repaired before a coating is applied.

What can Affect the Cost of a Commercial Roof Coating?

Can a Coating be Applied over an Existing Coating?

In many cases, yes — as long as the underlying roof system and old coating are still in good condition. The surface will need to be cleaned, repaired, and properly prepared to ensure good adhesion.

However, if the existing coating is peeling, blistering, or failing, it may need to be removed or repaired before applying a new layer.

I do not check the work. But I can say that the two men answered my question with courtesy. They assured me that the roof is in good order. And your company responded to the work order on short notice as coordination with plumber’s installation was key. My association with your company has always been more than satisfactory.
