When you observe your roof, does it look like it's in disrepair? If so, it may be time to call a professional. According to Forbes, asphalt shingles typically last between 15 and 30 years. Read on to learn about the four signs that it might be time for a roof repair.

1. Missing Shingles

Are there several missing shingles on your roof? In our experience, this situation can happen after a major hail or windstorm. The longer those shingles are missing on your roof, the more vulnerable the underlying structure is. After all, your shingles protect your roof from the elements, so the more exposed they are, the easier it is for moisture to get into your home.

2. Curled Shingles

Curled shingles are a sign of damage. Our experts have noticed that shingles may curl or crack after excessive exposure to UV rays. With that in mind, if your roofing hasn't had a protectant sealant on it, or if it's worn off, it may be time to call us for a roof repair.

3. Clogged Gutters

Based on our experience, a clogged gutter can't do its job properly. If you notice your gutters clogged with granules from your shingles, that's a sign that those shingles are losing their protective coating and are wearing down. Your gutters usher water away from your roof. However, when your gutters are filled with granules, leaves, and other debris, that water backs up onto your roof and traps moisture. In addition to affecting your roof, your clogged gutters are a danger to your foundation. If it can't usher water away from your roof, it also won't be able to usher water away from your basement and foundation area. That water can seep in and make your home structure more fragile.

4. Moss or Algae

Do you notice moss or algae growing on your roof? If so, it's not something to ignore, as our experience indicates that that's a sign of trapped moisture. After rain or other wet weather, this moisture normally evaporates off of your roof. However, with algae or moss covering up the shingles, that moisture is trapped between the shingles and the green growth. If the situation goes on too long, your shingles may begin to rot underneath the algae or moss.

As you can see, you have a few ways to tell if your shingles need repair or replacement. Your roof is there to protect your home, and you need to make sure that your roof is strong enough to do that. For expert roof repair you can trust, call Sterner Brothers Roofing for a consultation.
