Coastal Windows & Exteriors is a GAF Master Elite contractor and a woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine, with 7,000+ installations completed since 2011. Your asphalt shingles show clear warning signs before real damage sets in — curling edges, bald spots, and granule loss all signal it’s time to act.
Warning Signs Your Shingles Are Failing
- Granule Loss in Gutters: Finding granules means the protective coating on your shingles is wearing away fast.
- Curling or Buckling Edges: Warped shingles expose your roof deck to water with every storm that rolls through.
- Age Past Twenty Years: A roof more than 20 years old with recurring issues should be evaluated for replacement.
- Rising Material Costs Matter: Asphalt shingles average $4.46 per square foot nationally, making early action cost-effective.
- Daylight in the Attic: Visible light through your attic ceiling means gaps already exist in the structure.
- Missing or Cracked Shingles: Storm damage that leaves bare spots invites leaks fast, especially in winter.
Deciding When to Replace Your Shingles
Top Recommendation: Replace shingles showing granule loss or curling before the next winter.
Best for Minor Damage: A professional inspection to confirm repair versus full replacement.
Best for Planning Ahead: Financing your project early to lock in current material pricing.
