Residential Cool Roof Technology

Owens corning cool roof collection shingles are specially designed to reflect the sun s energy and absorb less heat than standard shingles without limiting your color options.

Residential cool roof technology.

Every shingle in the cool roof collection features a precise mix of solar reflecting granules to help comply with the solar reflectance index sri requirements of title 24 part 6 even with deeper vibrant colors. Dulux cool roof is our high build roof membrane that incorporates infracool technology to reflect more of the sun s light radiation from surfaces before it can be converted to heat. Residential roofing options include asphalt shingles metal clay tiles and concrete tiles. Cool roof coatings are white or special reflective pigments that reflect sunlight.

As in golf the higher the rating the lower the temperature. Dark surfaces also contribute to the urban heat island effect. The manufacturing and installation processes are different as are the life expectancies and maintenance requirements. There are many types of roof systems available but the surface exposed to the sun is the one that determines if a roof is cool or not.

There are different cool roof standards for commercial low slope roofs and residential steep slope roofs. Commercial cool roof options include bright white membranes and white coatings. Materials for steep sloped cool roofs include asphalt shingles metal roofing tiles and shakes. Historically cool roofs have been either white or some other lighter shade color.

While a sunlight absorbing black roof can reach up to 190 f in the summer a reflective roof s temperature can be as much as 60 f lower. Different cool roofing techniques are used for steep sloped roofs because of their different structure and materials. You can usually make a new or existing roof cool by selecting the appropriate surface. A cool roof reflects the sun s energy reducing rooftop temperatures.

Coatings are like very thick paints that can protect the roof surface from ultra violet uv light and chemical damage and some offer water protection and restorative features. Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products. Some of the more common types include modified bitumen roofs with reflective granules reflective coatings and thermoplastic membranes.

Cool roof technologies are not the same there are multiple options for creating a cool roof. Steep sloped roofs have an inclined roof line and are generally seen in residential settings.
