Won’t my roof get hotter when I have TemperGuard installed in my attic?
TemperGuard may increase the roof surface temperature by 2 to 5 degrees. To put it in perspective, the surface temperature of dark asphalt shingles can reach 190 degrees Fahrenheit on a hot sunny day. Most roofing manufactures recognize that adding TemperGuard to your attic will not harm your shingles.
