Water leaking in the attic

After a strong storm or wind-driven rain, take a look in the attic for signs of leaking. Ice damming can also cause water to enter the house if you don’t have an adequate shingle underlayment or if the flashing (the aluminum or steel used over roof joints, like chimneys and pipes) has deteriorated.

Missing, cracked, or curled shingles

If you see that your shingles are dry or practically break when touched, that means they have reached the end of their useful life and it’s time to replace the roof shingles.

Dark, "dirty-looking" areas on your roof

This could mean your roof has vegetation, fungus, mold, or algae growth, or that the shingles’ protective granules have been lost. This doesn’t mean you need to replace your roof, but these stains can reduce curb appeal. Cleaning the shingles is an option, but that could shorten their life. Fortunately, StainGuard® protection is available on many GAF Shingles, including Timberline® Cool Series Shingles, Timberline® Natural Shadow® Shingles, and Timberline® ArmorShield™ II Shingles. (StainGuard® protection is available only on shingles with StainGuard®-labeled packaging. See GAF Shingle & Accessory Ltd. Warranty for complete coverage and restrictions.)

Peeling or blistering interior or exterior paint

When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation. The air in the attic needs to flow freely from the soffit to the ridge to reduce humidity. Make sure there is a vent in areas such as the kitchen or bathroom. Dryers should vent outside.
