How Roof Coatings Work
A roof coating is a liquid-applied, fully adhered membrane applied directly to the surface of your existing roof. It is typically sprayed or rolled on, and once cured, it forms a seamless, flexible layer. This layer expands and contracts with temperature changes, creating a durable barrier against UV rays, water, and weather.
What roof coatings do
Seal & protect
- Fills small cracks, seams, and pinholes.
- Provides waterproofing depending on thickness and type.
- Shields the underlying roof from sun, wind, and rain.
Extend roof life
- Protects existing membranes such as TPO, EPDM, metal, or modified bitumen.
- Prevents premature roof replacement.
Improve energy efficiency
- Reflective coatings reduce heat absorption, lowering cooling costs.
- Many are “cool roof” rated and meet Energy Star standards.
Add fire and UV resistance
- Many coatings are fire-rated.
- UV protection prevents cracking, drying, and chalking of the roof system.
Types of roof coatings
Acrylic
Water-based, cost-effective, and reflective. Best for mild climates.
Silicone
Superior waterproofing, ideal for ponding water areas, and UV resistant.
Polyurethane
Tough and impact-resistant. Great for roofs with heavy foot traffic.
Asphalt-based/Aluminum
Traditional, affordable option with UV protection but less reflectivity.
Why property owners choose roof coatings
Knoxville property owners choose roof coatings because they provide significant cost savings, often 50–70% less than a full replacement, while also improving energy efficiency by reflecting heat and lowering rooftop temperatures by up to 60°F. Coatings extend roof life by 10–20 years with proper maintenance, install quickly with minimal disruption, and reduce landfill waste through sustainable, VOC-compliant options. Many systems also come with manufacturer warranties of 10–20 years, making them a practical and eco-friendly investment.
