Top Signs of Roof Damage Every Homeowner Should Know — And When to Call a Residential Roofer
Updated 2026
Your roof protects your home from rain, wind, and everything the seasons can throw at it — especially here in the Pacific Northwest. But even the best roofs need regular attention. Knowing the signs of roof damage early can save you from costly repairs and extend the life of your system. As a trusted Bellingham roofing company, we’re here to help you spot trouble before it becomes a major headache.
When To Call a Residential Roofer
1. Missing, Curling, or Damaged Shingles
Shingles are your roof’s first line of defense. When they begin to curl, crack, or go missing, it’s a clear sign of roof damage that water can find a way inside your home. These issues can be caused by age, wind, or moisture.
If you notice multiple shingles in poor condition or missing entirely, reach out to a professional right away. Even a few damaged shingles can let water in and cause bigger problems down the road.
2. Water Stains or Leaks Inside Your Home
Seeing water spots on ceilings or walls, especially after rain, is one of the most obvious signs of roof damage. It means water has already breached your roof and is entering your home.
Don’t wait for the next storm. A professional can locate the source of the leak and fix it before mold or structural issues develop.
3. Granules in Your Gutters or Downspouts
If you find shingle granules — the small, sand-like particles — in your gutters, it’s often a warning that your shingles are deteriorating. This loss reduces your roof’s ability to shed water effectively.
Excess granule loss suggests your roof is aging or has suffered weathering. A roofing expert can inspect and recommend repair or replacement options.
4. Sagging or Uneven Roofline
A sagging roof is a serious sign of roof damage and often points to structural issues or long-term water intrusion. This isn’t something to ignore — if the roof deck or supporting structure is compromised, problems can escalate quickly.
Contact a professional right away if you see any dips or soft spots in your roofline. Structural concerns require expert attention.
5. Moss, Algae, or Organic Growth
While moss might look charming at first glance, it traps moisture against roofing materials, accelerating shingle degradation and rot. These organic growths thrive in shaded, damp conditions common around Bellingham homes.
If moss covers large areas of your roof or seems to be lifting shingles, it’s time for a professional cleaning and inspection.
6. Age of Your Roof
Even well-maintained roofs don’t last forever. Asphalt shingles, the most common roofing material on residential homes, typically have a lifespan of about 20-25 years. Once a roof nears that age, hidden issues can pop up even without obvious symptoms.
If your roof is approaching its expected life expectancy — or you see multiple warning signs of wear — schedule a detailed inspection with a qualified Bellingham roofing company such as Axiom Roofing.
