Key Takeaways

  • Asphalt shingles typically last 15-30 years, but can suffer damage from storms, impact, or aging.
  • Missing, bruised, or cracked shingles are common signs of shingle damage that require attention.
  • Blistering, cupping, and granule loss are also indicators of shingle deterioration.

Identifying Common Signs of Shingle Damage

Asphalt shingles keep your house safe from rough weather. Sometimes, even the toughest roofs face trouble. It’s smart to check your roof often, especially after storms, for signs like missing shingles or exposed spots that might need fixing.

Missing Shingles

Big storms can tear shingles right off. This leaves the underlayment open to water and more damage. Quick action to cover these spots stops shingle damage and leaks. Making a habit of checking for missing shingles helps you protect your home.

Bruised and Cracked Shingles

Hail or rocks hitting your roof can bruise or crack shingles. This damage is easy to spot: look for darker areas or visible breaks. If you see them, it’s important to act fast. Making timely fixes keeps your roof strong against the next storm.

Your shingles might last 20 to 30 years, but they can still get hurt as they get older. Bad weather is a big threat. To keep your roof healthy and your house dry, regular checks and quick repairs are necessary. This protects your home from the elements.

Additional Indicators of Bad Asphalt Shingles

Watching your roof’s conditions is crucial as it gets older. Look out for signs like blistering, cupping, and granule loss. These issues can weaken your roof, risking leaks and water damage in your home.

Blistering and Cupping

Blistered shingles lose granules in spots, showing the asphalt underneath. This makes them prime for UV damage. Such blistering appears because of extreme heat, poor ventilation, or wrong ways of being put in place.

Cupped shingles have centers that dip or edges that rise. This causes water to sit on the roof. It could also lead to leaks and water damage.

Granule Loss

Older asphalt shingles start dropping their granules. You might find these in gutters or on the ground. Losing these granules puts the shingles at risk from UV damage, aging faster, and causing more leaks. If you see a lot of granules missing, think about a roof replacement.

Symptom Cause Potential Consequences
Blistered Shingles Excessive heat, poor ventilation, improper installation Increased UV damage, accelerated aging
Cupped Shingles Improper installation, normal aging Water pooling, potential leaks and water damage
Granule Loss Normal aging, exposure to elements Increased UV damage, accelerated aging, risk of leaks

Always keep a close watch on your roof. Take care of these problems early to make your shingles last longer. This will save you from dealing with expensive shingle deterioration and water damage.
