USA Nanocoat’s DuraRoof™, an advanced thermal insulation is specifically designed for roofing materials. This proprietary technology combines well-known reflective properties with cutting-edge materials that radiate heat away from the surface. This material is a cost-effective alternative to traditional roofing insulation. Not only does DuraRoof provide cost savings in terms of energy bills, but it also provides a water and moisture barrier to roofing, increasing the longevity of the roof itself.
DuraRoof has the ability to block and radiate the infrared energy back into the atmosphere is the key to energy savings when using dark colors. The blocked 53% infrared energy provides greater cost-saving than what is achieved by conventional white or light coatings if they successfully reflected all 43% of the visible light energy.

Reduces energy consumption
DuraRoof™ has exceptional bond strength with most construction materials and substrates and unlike conventional coatings, it can be applied to a clean surface without the use of a primer. Conventional elastomeric coatings inherently are soft and flexible to permit them to expand and contract with the heating and cooling roof. Over time this attribute, in conjunction with the continuous sun and heat exposure, causes them to become tacky. Airborne dirt and debris stick to the tacky surface and start diminishing the bright white color. This, in turn, compromises the reflective aspect of the roof coating, reducing the energy savings which eventually become negligible.
DuraRoof with its high tensile strength expands and contracts more like spring steel and will not become tacky over its useful life of 5 to 10 years depending on the maintenance. DuraRoof has outstanding abrasion resistance and is an excellent water and moisture barrier. It has built-in UV inhibitors to prevent degradation and chalking and non-polluting mildewcides prevent the growth of algae and other fungi. For optimal effectiveness and durability, a minimum of two coats DuraRoof should be applied. Each gallon will cover approximately a 100 square feet area depending on surface conditions and application efficiency. A median thickness coat will provide a 12 ml wet film which will dry to approximately 6 ml dry film. Thus after two coats, the overall effective dry film will be approximately 12 ml. Drying time at 70˚F and 50% relative humidity is 30 minutes to touch and 4 hours to recoat.
Application & Storage
Apply using brush, roller or airless spray equipment. Airless spray units will require a minimum 2500 psi pressure and a 0.027 (approx.) inch diameter spray tip. Filtering is not necessary but when used a 60 mesh filter is recommended. No thinning is necessary. When applying over very porous surfaces our Roof Protect should be applied in two coats. The first coat should be light, followed by a second heavier coat applied to create a cross hatch pattern. Subsequent coats, if needed, should be at normal strength. Do not apply to wet surfaces or at air, surface or product temperatures below 50˚F. Clean hands, tools and equipment promptly with soap and warm water.
All surfaces must be clean, sound and dry before painting. Remove dirt, chalk, rust, loose and peeling paint, oil, grease, wax or other surface contaminants with appropriate detergent and/or mechanical means. Remove mildew and sterilize the surface before coating. Use a masonry conditioner before painting porous, chalked or marginally prepared surfaces. All new masonry surfaces must be allowed to cure 30 days before application.
