High Reflective Roofing Material

Retrofit the roof with specialized heat reflective material.

High reflective roofing material.

High albedo products such as bright white paint are the most effective with a solar reflectance of 85. Reflective surfaces are a form of geoengineering. Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface. Re cover the roof with a new waterproofing surface such as tile coating replace the roof with a cool one.

Uv exposure is a consideration when it comes to material quality. 10 roof protector. White seal plus 100 acrylic elastomeric reflective roof coating with high uv ray reflectance model rc886 2 view the white elastomeric roof coatings. Metal roofs one of the most popular roofing materials used today can achieve a solar reflectance of over 70 allowing buildings to remain much cooler and lowering their energy costs.

Reflective surfaces can deliver high solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the surface and high thermal emittance the ability to radiate absorbed or non reflected solar energy. Cool roof reflective coatings. 9 arma foil radiant barrier high strength best residential roofing underlayment. Solar reflective shingles are designed specifically to reduce the absorption of the suns infrared radiation by reflecting ir rays off the surface of the roof thus not allowing the heat to be transferred to the interior of the structure i e.

The most well known type of reflective surface is the cool roof. If your roof is in poor condition or near the end of its life it is usually best to re cover replace or retrofit the roof. Metal is also extremely durable and weather resistant lightweight and 100 recyclable at the end of its useful life. The attic under the roof.

Energy star certified roof products reflect more of the sun s rays. To rate the level of reflectiveness of different products manufacturers have come up with a classifying system. Often the most cost effective retrofit is sealing a roof with spray foam insulation as this can also reduce thermal bridging at frames which are thermal leaks. A highly reflective and highly emissive painted or granular coated metal roof is optimal for reducing energy consumption and can actually re emit up to 90 of absorbed solar radiation.

This can lower roof surface temperature by up to 50f decreasing the amount of heat transferred into a building. If a roof underlayment comes with proper uv. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent. Reflective roof coatings act like mirrors reflecting the sun s radiant energy back into space.
