Like any component of your home, a shingle roof has a limited lifespan. Regular maintenance and repairs can help extend this period, but all homes will eventually need roof replacement. The average shingle roof last for 20 to 30 years. If your own has met or exceeded this limit, then you should enlist the services of a qualified inspector. Age aside, a few other indicators can reveal an immediate need for a replacement roof.
Curled or Buckling Shingles
As shingles age, they can become more susceptible to weather-related damage. In particular, shingles that have received a lot of wear from the sun will curl. New shingles can also curl or buckle if not installed correctly. Either way, the shingles will fail to protect your home from rainfall, and should get replaced.
A few missing shingles don’t create a huge reason for worry. A trained roofer can replace them, and hopefully match them to the color of your old roof. A roof that has shed a lot of shingles, however, has gone past its prime.
Chimney Flashing and Valleys
These mark the points where your roof becomes most susceptible to rainfall. If they’ve become damaged or worn, it serves as a sign you need roof replacement.
Your shingles get coated with granules to help protect against the elements and sun damage. If you notice a lot of granules while cleaning your gutters, you likely need roof replacement. Once the shingles begin to shed granules, your aged roof could fail at any time.
