Cool Roof Coat: Energy-Saving Roof Coating
Energy-Efficient Roof Protection That Lasts
Cool Roof Coat is a high-performance, water-based acrylic coating engineered to reduce heat transfer, extend roof life, and cut cooling-related energy use. Developed with NanoTech's proprietary high-solids additive formulation, this flexible membrane provides a durable, UV-resistant barrier that resists ponding water, cracking, and thermal degradation, even when dirty or weathered.
Unlike conventional reflective coatings, Cool Roof Coat actively rejects solar heat, with the barrier distributed through the film, and its CRRC-rated aged solar reflectance and SRI describe performance after three years of field exposure. It restores qualifying commercial roofs in place, so restoration can be priced against a full replacement on cost and schedule, and qualifying installations are eligible for many utility rebate programs.
Features & Benefits
Superior Thermal Control
- Actively rejects heat rather than only reflecting it, with the barrier distributed through the film
- Lowers surface temperatures and the cooling load that follows
- Maintains thermal performance even when dirty, measured by the CRRC aged solar reflectance and SRI ratings
Built for Durability
- High-solids formulation means fewer coats and longer life
- Flexible, seamless membrane resists cracking, impact, and UV damage
- Reduces roof degradation caused by heat, moisture, and expansion
Weatherproof Performance
- Waterproof barrier sheds rain and wind-driven moisture (positive drainage required)
- Stays flexible through the temperature swings of a commercial roof service environment
- Resists environmental wear in sun, snow, and storm-prone regions
Easy to Apply, Easy to Maintain
- Fast spray- or roll-on application, fully cures in 24 to 48 hours, walkable in 90 minutes.
- Minimal prep with no primer needed for many surfaces
- Compatible with NanoTech repair and prep products for seamless integration
Non-toxic, requires no PPE to apply
- Water-based with no-reportable VOCs
- Dramatically reduces Scope 2, cooling related emissions
- Engineered and assembled in the USA
Where to Use It
- Flat & Low-Slope Commercial Roofs
- Retail Centers & Warehouses
- Hospitals, Schools, & Government Buildings
- Metal, TPO, PVC, Mod Bit, Concrete, BUR Smooth, EPDM, and SPF Roofs
- Aging Roofs Where Restoration Is Worth Pricing Against Replacement
- Buildings in Hot, Sunny, or Storm-Heavy Climates
