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 HVAC energy use by up to 50%. Developed with NanoTech's proprietary additive and high solids formulation (71%), 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 through a combination of low thermal conductivity and high emissivity. It restores aging commercial roofs without tear-off, qualifying buildings for long-term energy savings, tax incentives, and reduced carbon output.
Features & Benefits
Superior Thermal Control
- Actively rejects heat with high reflectivity, High Emissivity, and low thermal conductivity
- Lowers surface temperatures and reduces HVAC loads by up to 50%
- Maintains thermal performance—even when dirty
Built for Durability
- High solids content (71%) = fewer coats and longer life
- Flexible, seamless membrane resists cracking, UV damage, and 2" hail impact
- Reduces roof degradation caused by heat, moisture, and expansion
Weatherproof Performance
- Waterproof barrier resists ponding water and wind-driven rain
- Stable across temperature swings from -22°F to 212°F
- 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 hours, typically walkable in 2 hours.
- 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
