Is It Time for Roof Repair? Key Signs to Watch for with Asphalt Roofing

Asphalt shingle roofs remain one of the most popular roofing choices for homeowners across New Hampshire. Known for their durability, affordability, and classic appearance, asphalt shingles provide decades of reliable protection. But like any part of your home, your roof won’t last forever. Recognizing the signs of wear early can help you avoid more extensive (and expensive) damage down the road. As a top-rated NH roof repair contractor, homeowners trust Derek Cook’s Roofing. Here, we guide you through the key indicators that it may be time to give your roof a little TLC.

 

1. Curling, Cracked, or Missing Shingles

Over time, harsh weather and UV exposure can cause asphalt shingles to curl, crack, or even go missing entirely. These are clear signs that your roof’s protective barrier is weakening. Shingles that no longer lie flat are more vulnerable to leaks, especially during heavy rain or snow.

If you’re seeing these issues on several areas of your roof, it’s best to call a professional for an inspection before water starts seeping in.

 

2. Granule Loss

Asphalt shingles are coated with protective granules that help block UV rays and extend the roof’s lifespan. If you begin to notice a buildup of granules in your gutters or at the base of your downspouts, your shingles are wearing down. This often happens toward the end of a roof’s life and is a strong indicator that repairs—or a replacement—may soon be needed.

 

3. Leaks and Water Stains

Water stains on your ceiling or walls are often the first signs homeowners notice when there’s a roof issue. Even small leaks can lead to significant damage, including mold growth and structural issues.

If you’ve spotted discoloration, peeling paint, or bubbling drywall, it’s time to contact a trusted roofing professional.

 

4. Sagging Roof Deck

A sagging roof isn’t just a cosmetic issue—it’s a serious warning sign. Sagging could mean that moisture or rot has compromised the underlying decking, which, left unchecked, can lead to dangerous structural problems.

A professional roofer can assess whether the sagging is due to aging materials or more severe issues that require prompt repair.

 

5. Moss or Algae Growth

While moss might give your roof a rustic look, it holds moisture against the surface of your shingles. Over time, this can accelerate deterioration and reduce the life of your roof. Algae streaks, while more of a cosmetic issue, may also signal trapped moisture.

 

6. Your Roof Is 15+ Years Old

Most asphalt roofs are designed to last between 15 and 30 years, depending on the quality of materials and installation. If your roof is approaching (or has passed) the 15-year mark, you should have it inspected regularly—even if no obvious signs of damage are present. Catching small issues early can prevent larger repairs later.
