Urethane Roof Coatings

Maintain and extend the life of an existing roof system with urethane—one of the most durable and impact-resistant roof coatings available.

Gaco polyurethane coatings go way back. We introduced our first urethane coating, U66 high solids polyurethane, in 1970. Since then, innovation has taken our urethane coatings to new heights with GacoFlex U91 and GacoFlex UA60.  

Urethane roof coatings are one of the best solutions when it comes to durability and impact resistance. Urethanes are not as temperature sensitive as acrylic chemistries. 

And urethane is incredibly versatile. Urethane coatings are commonly used for commercial roofing substrates, including EPDM, single-ply, BUR, modified bitumen, and concrete roof decks.

Key advantages of using a urethane roofing coating are: 

  • Urethanes offer best-in-class tensile strength, making them ideal for protection against extreme weather, moisture intrusion, and foot traffic. At the same time, urethanes are flexible. They can handle the frequent expansion and contraction of a roof’s surface in hot and cold climates. 
  • Urethanes are versatile. They can be sprayed or rolled and adhere to a wide variety of roof substrates. Urethane roof coatings are available in two product types, aliphatic and aromatic. Together, these products form a basecoat and a topcoat to increase durability and reflectivity. When combined, these coats also allow the urethane coating to stay cleaner and hold color better than other roof coating solutions. 

Urethanes are UV resistant. A reflective aliphatic topcoat reflects the sun’s rays to help building owners save money on heating/cooling costs

ALIPHATIC, AROMATIC, OR BOTH. Each type of urethane coating is best suited for a specific environment and application. Aromatic is generally the base coat, and aliphatic is the topcoat. Aliphatic offers greater UV protection and retains color for a long time. Together, these urethane coatings provide a total waterproofing solution.

EXCEPTIONALLY STRONG. Few coatings compare to urethane when it comes to durability and strength. Urethane is more resistant to impacts, moisture, and thermal movement. 

ADHERES TO ALMOST ANY SUBSTRATE. Unlike some other roof coatings, urethane coatings are versatile enough for application on nearly any substrate or roof—sloped or flat, textured or smooth. Some contractors will even use urethane as a base coat for silicone roof coatings. 

HIGHLY REFLECTIVE & UV STABLE. A reflective aliphatic urethane topcoat helps building owners save money on heating and cooling costs by reflecting the sun’s rays instead of absorbing them. Urethane’s reflective nature supports savings no matter the season, thanks to optimal UV resistance and insulation. 

AESTHETICALLY PLEASING. An aliphatic urethane topcoat resists dirt-pickup and won’t change color because of UV damage. You can count on urethane to look good and stay that way.
