Five Tips to Protect Your Roof from Extreme Summer Heat

Insulate the Attic

“Insulation in the attic is very important,” says Feller. Laying insulation on the attic floor keeps your house cooler. But to protect the roof itself, it’s more important to insulate the underside of the roof decking. She suggests spray foam for this.

Spray foam becoming more popular in Texas, she says, because it prevents heat from radiating through the roof decking. It also keeps the attic and house cooler.

However, Feller points to an important downside to spray foam: It makes it harder to detect leaks. Water tends to track between the insulation and the decking, and the place where it finally drips into the attic could be many feet away from the actual leak.
