How does it work?How does it work?
The idea is simple: White roofs reflect The idea is simple: White roofs reflect sunlight and emit heat better than darker onessunlight and emit heat better than darker ones
On a hot, sunny, summer On a hot, sunny, summer day, traditional roofing day, traditional roofing materials may reach 190° Fmaterials may reach 190° F
Cool Roofs only reach Cool Roofs only reach peak temperatures of peak temperatures of 120° F120° F

““Where Cool Roofs have been installed, the Where Cool Roofs have been installed, the outside temperature in the immediate area is outside temperature in the immediate area is cooler than in areas a block away without the cooler than in areas a block away without the roofs.”roofs.” -Audrey Chang, Cool Roof Rating Council-Audrey Chang, Cool Roof Rating Council
Eliminates tear-off & disposal of waste materials Eliminates tear-off & disposal of waste materials that occurs with traditional roof upgradethat occurs with traditional roof upgrade
““Air conditioners use up to 1/6th of the Air conditioners use up to 1/6th of the electricity in the U.S. and on hot summer electricity in the U.S. and on hot summer days consume 43% of the U.S. peak power days consume 43% of the U.S. peak power load.” load.” -Union of Concerned Scientists-Union of Concerned Scientists
Cool roofs exhibit two other Cool roofs exhibit two other advantages over darker roofs:advantages over darker roofs:
Cool roofs last Cool roofs last longerlonger
Changing Changing temperatures cause temperatures cause a dark roof to expand a dark roof to expand and contract and contract
Since white roofs Since white roofs expand less in expand less in summer time, the summer time, the roofing material is roofing material is worn lessworn less

A Cool Roof can be recoated with one white A Cool Roof can be recoated with one white acrylic application (no need for the mesh or acrylic application (no need for the mesh or extra layers)extra layers)

How much does it cost?How much does it cost? Just like almost all energy-efficiency Just like almost all energy-efficiency
upgrades, the up-front cost of a Cool Roof upgrades, the up-front cost of a Cool Roof is slightly higher than a traditional roofis slightly higher than a traditional roof
▪ But once you factor in maintenance costs over the life of each roof and energy cost-savings provided by a Cool Roof, it is clearly an economically wise investment
In lieu of a complete Cool Roof system, you can opt In lieu of a complete Cool Roof system, you can opt for 1 or 2 layers of the white acrylicfor 1 or 2 layers of the white acrylic
