When your roof is covered in asphalt shingles, you can expect that your roof will last around 15–20 years. The roof may last longer if you live in an area that has a moderate climate and your roof isn't subject to harsh conditions. In the reverse, if your roof is exposed to long hours of hot sunlight or temperature extremes, your asphalt shingle roof may disintegrate more rapidly. While you may not pay much attention to your roof until there is a leak, once there is a problem with your roof, it's time to have the structural integrity checked by a roofing specialist.
When Your Shingles Start to Fade
One of the first signs that asphalt shingles are beginning to deteriorate is that they will start to fade. While this doesn't mean that your roof is going to leak any time soon, you may notice small granules of asphalt in your gutters or on the ground. If your roof is subject to harsh sunlight throughout the day, this is going to fade your shingles. Once shingles start to fade, they may begin to dry up and crack. When an asphalt shingle starts to crack, it may let in water when it rains.
If Your Shingles Are Curling
If your asphalt shingles are starting to curl throughout your roof, this is a sign that your shingles are not going to last much longer. When you have a leak, this can be repaired, but it is likely that you'll have to replace your roof in the near future. When your shingles are curling, the structural integrity of your roof is at risk. This is a sign of a systemic problem with your roof and requires total replacement.
When a Leak Occurs from Storm Damage
Storm damage can cause your leak to roof, even if it is brand new. When your roof is damaged because of severe weather, it's important to have the damage fixed right away. This is not a sign that your entire roof is failing, but that an accident occurred to cause your roof to fail temporarily. If there is nothing wrong with the rest of your roof, you won't have to get it replaced any time soon.
When you have an asphalt shingle roof, paying attention when your roof leaks is important. Get any leaks identified and repaired, and listen to a roofing company like Ray's Harford Home Improvement Contractors Inc if they recommend getting your roof replaced.
