Depending on the composition of your roof, you can expect it to last between 20 to 50 years. The lower end tends to be asphalt shingles, while cement shingles and wood sit in the middle, and tile or slate last the longest.

Of course, these estimates are just averages. How long do roofs last, really?

It all depends on the severity of the elements they’ve been exposed to. Storm damage is one of the most severe conditions that may necessitate roof replacement.

To figure out if your roof may need replacing, take a look at the six signs below.

1. Check the Inside

Although signs of external roof damage may be obvious, many homeowners forget to check their roof from the inside. Keep the attic dark as you look for light creeping in through the roof.

If you see any light streams, this means there are holes or cracks in your roof. This also means water has been getting in. Make sure to immediately schedule a roof repair before you experience permanent water damage. 

2. Drooping or Sagging

A drooping or sagging roof is an ominous sign of water damage. It may mean that moisture has rotted out the boards.

If you find a sagging spot, take something long and firm to poke at it. If it gives easily, you need immediate repair.

3. Curling or Cracking

Curling or cracking shingles are not as serious as the other items on the list, but they are susceptible to damage. A little wind or rain might ruin them completely.

It’s best to keep up with your roof maintenance by replacing shingles like these as soon as you can. Good roof maintenance like this prevents further damage in the future.

4. Dark Stains or Streaks

Dark stains or streaks are similar to drooping or sagging areas; they indicate water damage. These areas are especially obvious from the inside of the home but may be difficult to spot from the outside, so keep an eye out.

5. Water Leaks

As indicated by a few signs on this list, water damage is one of the most important things to look out for. An obvious water leak, like water dripping from the ceiling, is a huge red flag. Don’t try to compensate with a bucket — have your roof evaluated by a professional ASAP.

6. It’s Been a While

Even if you haven’t noticed any of the signs listed here, your roof may still have reached its expiration date. A good way to tell is to see if others in your neighborhood have had their roofs replaced lately.

Although your roof may seem like it’s in good shape, no material lasts forever. Have a contractor make sure it’s still safe.

How Long Do Roofs Last?

There’s no exact formula to figure out how long do roofs last. However, if you’re seeing the signs listed above, it’s time to call a professional. Make sure a licensed contractor takes a good look at your roof and determines if the wear and tear carries a potential safety risk.
