Bob Vila Radio: Cool Roofs
When it comes to keeping your home cool this summer, your roof—not your air conditioning system—IS YOUR first line of defense.
Listen to BOB VILA ON COOL ROOFS, or read text below:
Passive cooling techniques like installing light-colored roofing will deflect more heat than black asphalt will. porches and large overhangs make your roof into an umbrella to shade your house.
While insulating the floor of your attic is essential, insulating between the roof joists as well creates an insulated buffer zone between your living space and the scorching sun.
The temperature on your roof can reach 160 degrees on a hot summer day. Builder’s foil or foil-faced plywood installed between the underside of the roof and the insulation can keep a lot of that heat from radiating into your attic. These radiant barriers cut cooling costs by 10 to 15 percent in homes with R-19 ceiling insulation, so they pay for themselves in just a few years.
