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. 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. This results in lower absorption of solar heat and a cooler roof. 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. 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. The manufacturing and installation processes are different as are the life expectancies and maintenance requirements. You can usually make a new or existing roof cool by selecting the appropriate surface.

Steep sloped roofs have an inclined roof line and are generally seen in residential settings. Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away. 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. Some of the more common types include modified bitumen roofs with reflective granules reflective coatings and thermoplastic membranes.

Different cool roofing techniques are used for steep sloped roofs because of their different structure and materials. Cool roof technologies are not the same there are multiple options for creating a cool roof. Dark surfaces also contribute to the urban heat island effect. There are different cool roof standards for commercial low slope roofs and residential steep slope roofs.

Residential roofing options include asphalt shingles metal clay tiles and concrete tiles. We re your southern california spray foam contractor for spray foam insulation and spray polyurethane insulated foam roof spf roof coated foam roof commonly known as cool roof the most proven durable and energy saving roofing system available today. Historically cool roofs have been either white or some other lighter shade color. Cool roof coatings are white or special reflective pigments that reflect sunlight.

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