Residential Cool Roof Technology

Steep sloped roofs have an inclined roof line and are generally seen in residential settings.

Residential cool roof technology.

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. 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. As in golf the higher the rating the lower the temperature.

You can usually make a new or existing roof cool by selecting the appropriate surface. Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. 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.

Dark surfaces also contribute to the urban heat island effect. Some of the more common types include modified bitumen roofs with reflective granules reflective coatings and thermoplastic membranes. There are different cool roof standards for commercial low slope roofs and residential steep slope roofs. Different cool roofing techniques are used for steep sloped roofs because of their different structure and materials.

Commercial cool roof options include bright white membranes and white coatings. Cool roof coatings are white or special reflective pigments that reflect sunlight. 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. Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away.

Materials for steep sloped cool roofs include asphalt shingles metal roofing tiles and shakes. 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. Cool roof technologies are not the same there are multiple options for creating a cool roof.

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. 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.
