Your asphalt shingle roof can last 20 years or more, but this is going to depend on a number of variables. If your roof is in the direct sunlight or is exposed to harsh weather, you may get less life out of your asphalt shingles. You may notice a small leak in your roof coming in through the ceiling. If the problem is localized, your roofer will fix it and you shouldn't have any new leaks in the near future. When your roofer suggests a new roof, this is usually because the shingles on your roof are deteriorating and you are going to start having leaks in other areas.
System Roof Problems Require a Replacement Roof
While you can try the repair it and wait method of dealing with roof leaks, this often leads to significant water damage in your home. When your asphalt shingle roof starts to leak because of shingle deterioration, it is only a matter of time before you have many leaks coming into your home. Whenever you have more than one leak in your house at a time, it is probably an issue with your roof that requires a replacement.
If Your Shingles Are Curling
Asphalt shingles break down over time. You may notice a loose shingle on the ground, or see grains from your shingles near your downspout. While a loose shingle can be due to a bad storm, curling shingles indicate that your shingles are breaking down. When you have shingles that are falling off of your roof and you see cracked, curled shingles, you need to replace your roof as soon as possible.
After a Heavy Storm
Even if your roof is new, you can have leaks in your roof caused by storm damage. Any time you find water leaks in your ceiling or walls, your roof is suspect. Sometimes your gutters can be full and cause water to come into the home from underneath the roof. If you have a heavy storm that drops large branches on your home, it's important to have your roof inspected by a professional. You may have damage on your roof that you can't see that needs to be repaired.
Asphalt shingles can protect your home for years until they begin to disintegrate. Chronic leaks, curling shingles, and finding shingles on the ground usually mean you need to have a new roof installed. Contact a residential roofing specialist when you are concerned about the roof on your home.
