The national average cost for replacing a roof is approximately $8,000. It’s one of the more significant repair costs when you own a home.

Many homeowners delay a roof replacement as long as possible but that can lead to even higher repair costs. If you’re debating about replacing a roof and wondering how often it needs to get done, let’s take a look.

Life Expectancy of Different Roofing Materials

There’s no one-size-fits-all answer to the question of how often should you replace your roof. The type of roof on your home plays a big part in the decision since some materials have longer lifespans than others.

Here are the typical life expectancies of the most common types of roofs:

  • Composition shingles: 12 to 20 years
  • Asphalt shingles: 15 to 30 years
  • Wood shingles: 20 to 25 years
  • Metal: 50 (steel, aluminum) to 100 (copper, zinc) years
  • Slate: 100 years or more

The material isn’t the only consideration though. Several other things play a part.

Other Factors to Consider

The climate in your area is another significant factor in replacing your roof. If you live in an area that sees extreme weather, either cold or heat, it can shorten the lifespan of your roof.

If you’re in an area that gets hit with major storms, that can also play a part. High winds and driving rain can knock roofing materials loose.

How well you maintain your roof over the years is also important. If you never do any kind of maintenance, moss, algae, and other materials can build up. If they’re left unchecked, they can work their way under the roofing material and knock it loose.

Poor maintenance can also lead to leaks. Once water gets through the top layer of the roof, it can speed up the deterioration of the materials.

Along the same lines, if you neglect to repair damage to your roof, it can lead to leaks and a general weakening of the roof. If the damage gets bad enough, you may have no choice but to replace it.

What to Look for When Debating About Replacing a Roof

There are several common signs that it might be time for a roof replacement.

Loose or Damaged Shingles

Loose, damaged, or missing shingles may be a sign that it’s time to replace the roof. Once the materials reach a certain point of wear and tear, it’s no longer possible to do spot repairs.

Sagging Roof

If your roof is sagging in spots, it’s likely a sign that the underlying plywood or other materials have worn out. This could be due to their age or it could be a result of water damage but either way, it likely needs to get replaced.

Mold or Rot

This is another sign of potential water damage. If there’s visible mold or rot on your roof, it’s time for a replacement. Mold can lead to health-related issues so it needs to be addressed as quickly as possible.
