Residential Cool Roof Technology

A cool roof reflects the sun s energy reducing rooftop temperatures.

Residential cool roof technology.

As in golf the higher the rating the lower the temperature. Steep sloped roofs have an inclined roof line and are generally seen in residential settings. 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.

Historically cool roofs have been either white or some other lighter shade color. Commercial cool roof options include bright white membranes and white coatings. 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. The manufacturing and installation processes are different as are the life expectancies and maintenance requirements.

Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away. Cool roof technologies are not the same there are multiple options for creating a cool roof. Cool roof coatings are white or special reflective pigments that reflect sunlight. Residential roofing options include asphalt shingles metal clay tiles and concrete tiles.

Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. 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. This results in lower absorption of solar heat and a cooler roof. 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.

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. 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. 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. Materials for steep sloped cool roofs include asphalt shingles metal roofing tiles and shakes.
