Elastomeric roof coatings are revolutionizing the way homeowners and facility managers protect low-slope and flat roofing systems—especially when you choose a proven performer like GAF Elastomeric Roof Coating. By forming a flexible, weatherproof barrier over existing materials, these high-performance sealants not only stop leaks in their tracks but also reflect damaging UV rays, reduce heat gain, and extend the life of your roof by years.
What Makes GAF Elastomeric Roof Coating Stand Out?
Acrylic-Based Durability
GAF’s proprietary water-based acrylic formula cures into a seamless, rubber-like membrane that resists cracking, chalking, and peeling over time.
Superior Reflectivity
Available in a bright white “cool roof” finish, it meets ENERGY STAR® requirements to help lower rooftop temperatures and reduce air-conditioning loads.
Crack-Bridging Performance
With excellent elasticity, the coating stretches to bridge hairline cracks and shrinks back without losing adhesion, preventing new leaks from forming.
Eco-Friendly & Low VOC
The waterborne formulation emits minimal volatile organic compounds (VOCs), making it safer for applicators and kinder to the environment.
Key Benefits of Applying GAF Elastomeric Coating
Leak Prevention
By filling micro-fissures in built-up, modified bitumen, metal, and concrete roofs, the coating seals out water before it has a chance to penetrate.
Energy Savings
Reflective pigments bounce back solar radiation, cutting rooftop temperatures by up to 50°F and lowering cooling costs in warm climates.
Extended Service Life
Rather than replacing an aging roof, a top-quality elastomeric coating can add a decade or more of protection at a fraction of the replacement cost.
Low Maintenance
The smooth, monolithic surface resists dirt and mold—periodic inspections and occasional recoats are all that’s needed to keep your roof in peak condition.
Best Practices for Application
Thorough Surface Prep: Power-wash away debris, loosened material, and mildew. Ensure the deck is fully dry before coating.
Weather Awareness: Apply when ambient and substrate temperatures are above 10°C (50°F) with no rain forecast for at least 24 hours.
Two-Coat System: Use a first “bond” coat at 20 mils WFT (wet film thickness), allow proper cure time, then follow with a second waterproofing coat.
Proper Coverage: Aim for 1–1.5 gallons per 100 sq ft per coat—refer to GAF’s technical datasheet for exact mil thickness guidelines.
