Key Danger Signals
Don't get caught with sudden, costly repairs. Keep a close eye on your roof and find out how to spot problems - including these 7 key danger signs - before they severely impact your wallet.
1- Attic Leaks
Check your attic after severe weather. A leak could mean some shingles are damaged, the underlayment a protective barrier between your shingles and the plywood of your roof has failed, or flashing the material that seals joints on your roof has deteriorated.
2- Excessive energy costs
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.
3- Blistering or peeling interior or exterior paint
Moisture trapped in the house due to poor ventilation can cause exterior paint to peel and blister.
4- Stains on interior ceilings and walls - mold or mildew growth
Stains, or worse, mold, can be caused by leaks from outside the house or moisture trapped inside.
5- Exterior decay in sheathing and/or siding
Excess moisture can also contribute to decay.
6- Missing, cracked, or curled shingles
Dry, cracked, or easily broken shingles have reached the end of their useful life, and its time to invest in a new roof.
7- Dark, dirty-looking areas on your roof
Vegetation, fungus, mold, or algae growth can cause dark stains on your shingles.
