Residential Cool Roof Technology

Commercial cool roof options include bright white membranes and white coatings.

Residential cool roof technology.

Cool roof requirements vary by region but generally are based on solar reflectance and. Total protection is more than shingle deep. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. With all the focus on green building these days the market is heating up with interest in cool roof technology.

Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. Residential roofing options include asphalt shingles metal clay tiles and concrete tiles.

In light of this cool roofing is one of the main strategies used to prevent future occurrences of heat island effects cool roofing is an emergent and powerful technology used for temperature control of buildings and areas. Stay comfortable stay cool the owens corning cool roof collection helps keep your roof cooler for a more comfortable home. What constitutes a cool roof. There are different cool roof standards for commercial low slope roofs and residential steep slope roofs.

Historically cool roofs have been either white. Surenail technology nailing zone performance streakguard algae protection cool roof energy performance roofing system. Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away. 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.

This results in lower absorption of solar heat and a cooler roof. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. Energy cost savings are not guaranteed and the amount of savings may vary based on climate zone utility rates radiative properties of roofing products insulation levels hvac equipment efficiency and other factors. As in golf the higher the rating the lower the.
