Residential Cool Roof Technology

Some of the more common types include modified bitumen roofs with reflective granules reflective coatings and thermoplastic membranes.

Residential cool roof technology.

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. 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. Dark surfaces also contribute to the urban heat island effect. Commercial cool roof options include bright white membranes and white coatings.

There are different cool roof standards for commercial low slope roofs and residential steep slope roofs. 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. 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. The manufacturing and installation processes are different as are the life expectancies and maintenance requirements.

Cool roof technologies are not the same there are multiple options for creating a cool roof. Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away. Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. Cool roof coatings are white or special reflective pigments that reflect sunlight.

Historically cool roofs have been either white or some other lighter shade color. Residential roofing options include asphalt shingles metal clay tiles and concrete tiles. Materials for steep sloped cool roofs include asphalt shingles metal roofing tiles and shakes. Different cool roofing techniques are used for steep sloped roofs because of their different structure and materials.

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. As in golf the higher the rating the lower the temperature. 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. This results in lower absorption of solar heat and a cooler roof.

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