How Long Does an Asphalt Shingle Roof Last?

If it’s time for a new roof, you might be considering an asphalt shingle roof. These are among the most popular roofs, and for good reason: They’re durable, affordable, and available in various styles and colors.

However, you might be asking yourself, how long does an asphalt shingle roof last? On average, it’s typically around 25 years, but a lot of factors will influence your roof’s longevity.

We’ll delve into this by reviewing these factors, as well as which signs might indicate the roof is near the end of its life, and tips on extending the lifespan of your asphalt shingle roof.

Factors Influencing the Lifespan of an Asphalt Shingle Roof

Since the lifespan of this type of roof has quite a wide range, it’s important to understand the factors that might make a roof more or less likely to last up to its maximum potential.

For starters, the climate plays a significant role. If you live in an area with harsh weather conditions, such as hurricanes, heavy rainfall, extreme temperatures, and heavy snow, wear and tear on the roof will be accelerated. This can reduce the lifespan of the roof.

The quality of both the materials and the installation can impact your roof’s longevity. Installation mistakes, such as improper fastening and inadequate underlayment or flashing, can lead to various issues that reduce the roof’s lifespan.

Hiring a professional roofing company like Erie Home can help you maximize your roof’s lifespan. We can also help you choose the best quality shingles possible for your project, making it more likely they’ll be able to stand up to the elements.

Besides a professional installation, all our asphalt shingle roofs also come with a transferable limited lifetime warranty, so you can rest assured that your investment is protected throughout the lifetime of your roof.

Roof ventilation is another factor, particularly in areas with a hot climate. Good ventilation prevents excessive heat buildup, which can warp shingles and reduce their longevity.

Finally, regular maintenance and inspections can help you address minor problems before they become something major. Debris buildup, mold, and damaged shingles can all be treated early, minimizing their impact on the lifespan of the roof.

Signs an Asphalt Shingle Roof Needs Replacement

You may wonder how you’ll know when your roof is nearing the end of its life. Here are a few signs to watch out for:

Roof and shingles damaged from water leak
  • Visible damage. If you can see missing shingles, cracks, and curling edges, particularly if it’s happening on different areas of the roof, this is a clear sign it might be time for a replacement. If you see it only in one small section, there may be water damage or some other issue that can be addressed and repaired to save the rest of the roof.
  • Roof grit in the gutters. Over time, the elements will begin to wear down the asphalt shingles, and you’ll start to see grit from the roof in the gutters. If you clean your gutters and notice a lot of sand-like grit, it is a sign the roof might be nearing the end of its lifespan.
  • Leaks or water damage. While a storm can damage just a few shingles and lead to water leaks or damage, water stains on the ceilings or walls clearly indicate something needs to be fixed immediately.
  • Many years have passed. Over time, the roof will need more frequent inspections to ensure it’s still in good shape. If you’re past the 15- or 20-year mark, be alert for signs that the roof needs to be replaced.

Extending the Life of Your Asphalt Shingle Roof

The good news is that while you can’t control the weather or change who installed your roof in the first place, there are a few things you can do to maximize the roof’s lifespan.

One thing is to regularly clean debris from the roof. Check for damaged shingles, and keep the gutters clean so they can drain properly and prevent ponding and ice dams. By keeping on top of routine maintenance, you can often prevent larger issues.

Have repairs done promptly. Your periodic inspections might reveal issues such as curling shingles, spots where mold accumulates, or missing shingles. Have these issues addressed right away by calling trusted roofing professionals like Erie Home.
