Typically, you can expect an asphalt shingle roof to last for about 15-25 years before needing to be replaced. In order for your roof to reach its longest possible lifespan, however, you'll need to keep it properly maintained. From regular roofing inspections to preventative repairs, a little proactive maintenance can go a long way on a residential roof.
Still, if your asphalt shingle roof is nearing that 15-year mark, you may be wondering whether replacement is imminent. There are a few signs you'll want to watch for that could indicate the end of your roof's useful life.
Shingle Granules in Gutters
It is not uncommon to find small asphalt granules in your gutters immediately after a roof is installed. After that, however, an asphalt roof should not shed significant amounts of granules until it is nearing the end of its lifespan and needs replacement. If you've noticed large amounts of shingle granules inside your gutters, this could be a sign that your shingles are beginning to fail.
A Visibly Saggy Roofline
When shingles fail and allow water underneath them, the wooden boards that make up your home's roof can rot over time. This is a process that will not happen overnight; it will happen after months or even years of moisture problems. Eventually, you may even be able to notice a visibly saggy roofline on your home. Usually, when this happens, it is not just the roof that needs replacing — but some of the home's roof framing as well.
Cracked, Damaged, or Missing Shingles
A few cracked or damaged shingles here and there do not necessarily mean your entire roof needs to be replaced. However, there comes a point where it may make more financial sense to simply replace your entire roof rather than continuing to make small repairs here and there. This may be the case if your roof is already nearing that 15-year mark.
Interior Water Staining
If your roof is in enough disrepair that you have moisture problems inside your home, including leaks and water stains on your ceilings, then it's probably time to have a new roof installed. At the very least, you'll want to ask about re-shingling to provide your home with the protection it needs against moisture.
Nobody wants to pay to replace a roof if they don't need to. Ultimately, the best way to determine whether your home needs a new roof is to have a professional roofing contractor come take a look.
