After a strong storm or wind-driven rain, take a look in the attic for signs of leaking. It could indicate damaged shingles, inadequate underlayment or deteriorated flashing.
Moisture trapped in the house due to poor ventilation can cause exterior paint to peel and blister.
Stains, or worse, mold, can be caused by leaks from outside the house or moisture trapped inside.
Excess moisture can also contribute to decay.
Dry, cracked, or easily broken shingles have reached the end of their useful life, and its time to invest in a new roof.
Vegetation, fungus, mold, or algae growth can cause dark stains on your shingles. That doesnt necessarily mean you need a new roof, but if you do choose to replace your shingles, ask for StainGuard protection available on many GAF Shingles, including Timberline Cool Series Shingles, Timberline Natural Shadow Shingles, Timberline ArmorShield II Shingles, and Timberline Ultra HD Shingles.
(StainGuard protection is available only on shingles with StainGuard -labeled packaging. See GAF Shingle & Accessory Ltd. Warranty for complete coverage and restrictions.)
Inadequate ventilation can possibly drive up your household cooling costs by trapping hot air in the attic. Attic moisture can also drip into your insulation, reducing its effectiveness.
Why wait for the drip, drip, drip of a damaged roof Its a good idea to inspect your roof regularly, particularly if you live in areas of the country that experience extreme weather. You can inspect your roof yourself by either climbing on your roof or by using binoculars from the ground.
If you choose to go up on the roof yourself, remember to always utilize proper safety equipment to prevent falls or injury. See our Safety section for more details.
