Your attic needs to breathe. Poor ventilation may lead to excess heat and moisture and potential roof system degradation. The attic ventilation options that are best for your home will vary based on the style of your roof to ensure that each attic space has a balanced system for intake and exhaust. Balanced systems need to draw in fresh air and export hot, moist air.

If you drive down virtually any residential street in the U.S. or Canada, there's a chance you'll see at least one roof stained with black or dark brown streaks. Many assume the stains on their roof shingles are from mold, mildew, moss, or even tree sap. They're often actually caused by tiny bacteria called Gloeocapsa magma, AKA "blue-green algae". When you see the dark stains, you're not looking at the algae, but at the hard, dark coating it generates to protect itself from damaging UV rays.
When snow and ice are in the forecast, it makes sense to start thinking about safety precautions for your family. Those preparations extend to your home as well—the formation of ice dams on your roof can cause significant damage.
Why Attics Get a Bad Rep Attic's get a bad rep. Hot, unfinished, dark spaces, often hard to access, filled with insulation, ductwork, and old family heirlooms make attics an undesirable space. And scary movies like The Grudge certainly don't make attics any more appealing. What a shame. Perhaps if more people understood the potential that is just waiting to be unveiled, we'd have a very different viewpoint on these underserved spaces.

There's an old saying that it takes a village to support a family. In late October, it took 75 volunteers—including many GAF employees—working together with Habitat for Humanity of Tuscaloosa, Alabama to meet one goal: making a family's dream of homeownership come true. The best part? It took just five days.
