A typical asphalt roof lasts an average of 20 years.

But, roof damage can cut the average lifespan in half. If you’ve experienced a rough winter or strong storms, it’s time to take a look at your roof. But what exactly are you looking for?

Keep reading to discover indicators of roof damage. If you see any of these signs, you need to get your Annapolis roof replaced before it’s too late.

Shingle Granules

Be on the lookout for shingle granules if you suspect roof damage. Shingle granules are small pieces of asphalt that have broken away from your shingle.

These granules separate from your shingles naturally as your roof ages, so seeing a few is no big deal. But, if you notice a lot of granules in your gutter or surrounding one area of your roof, this is cause for concern.

An abundance of granules means that your shingles are deteriorating faster than they should.


One of the more obvious signs you need a new roof is a sagging or sinking roof.

Take a few steps away from your house and look at your roof. Check the natural lines of your roof. Is there an area that is sinking or sagging?

This is a sign of serious roof damage and you should address it immediately. Often, it means that the material under your shingles is deteriorating.

Impaired Shingles

Asphalt shingles show damage in a variety of ways. If you’re unsure if your roof is damaged, take a good look at your shingles.

First, look over the roof as a whole. Are there areas where shingles are missing? If so, you’ve experienced roof damage.

Even if all your shingles are there, there are other signs of damage. Look closely for cracked or curled shingles. If only a few shingles have damage, you may be able to replace them instead of your whole roof.

Algae or Moss

While you are looking at your roof, do you notice any green discoloration? If so, your roof may be growing algae or moss.

Both algae and moss grow in areas where there is excess moisture. When your roof is working properly, all water should run off your roof and into your gutters. If water is pooling or collecting in areas, you have a problem.

There are ways to clean the growth off, but make sure there is not an underlying problem.

Leaks or Water Spots

The last place you might think to check for roof damage is inside your house. But signs of a roof leak appear in the interior of your home.

It’s hard to miss an active leak inside your home, but water spots are easier to ignore. Check your ceilings and attic space for any signs of water damage. If water is making its way into your home, you know your roof isn’t doing its job.
