Roof Coatings

Roof coatings can extend the life of an existing roof by 10 to 20 years at a fraction of the cost of full replacement. They reflect UV, seal minor cracks, and create a seamless waterproof membrane over the existing substrate. Most commercial and residential flat or low-slope roofs are candidates for coating as long as the deck and insulation underneath are still in good shape.

We carry some professional grade elastomeric coatings that meet ASTM D6083 (acrylic), ASTM D6694 (silicone), and ASTM D6947 (polyurethane) specifications. These are the same products commercial roofing contractors spec on the job, not the consumer-grade coatings you find at big-box stores.

Which Type Do You Need?

Not sure which chemistry is right for your roof? Our elastomeric roof coating guide breaks down the differences, including a recoat compatibility matrix so you know what goes over what.

Application and Coverage

All elastomeric coatings go on in two coats applied perpendicular to each other. Coverage runs 65 to 100 square feet per gallon per coat, depending on the product and substrate condition. Warranty length is tied directly to dry film thickness: 20 mils gets you 10 years, 30 mils gets you 20.

For step-by-step application instructions, surface prep checklists, and coverage rate tables, see our how to apply elastomeric roof coating guide.

Cool Roof Compliance

White elastomeric coatings meet California Title 24 cool roof requirements and qualify for CRRC and Energy Star ratings. A reflective coating can cut rooftop surface temperatures by 50 to 60 degrees, reducing cooling costs and helping meet energy code on reroofing projects.

Tip: If you are coating a roof in a jurisdiction that requires cool roof compliance, verify the product has a current CRRC listing before you buy. Aged reflectance values (measured at 3 years) are what code enforcement looks at, not initial reflectance.

Safety on the Roof

Roof coating work involves chemical exposure, slippery surfaces, and fall hazards. Our roof coating safety kit guide covers the PPE and first aid supplies every crew should have on site, and our fall protection guide covers OSHA requirements for low-slope roof work.
