How Do You Know When Your Seattle Roof Needs Replacing?
Your roof protects everything underneath it — your family, your belongings, and your home's structure. In the Pacific Northwest, roofs take a beating from constant rain, moss growth, wind, and occasional hailstorms. Knowing when to repair versus replace can save you thousands.
Here are the 7 signs every Seattle homeowner should watch for:
1. Your Roof Is Over 20 Years Old
Most asphalt shingle roofs last 20–30 years depending on the materials and installation quality. If your roof was installed more than 20 years ago, it's time for a professional inspection — even if you don't see visible problems. Aging roofs can fail suddenly during Washington's winter storms.
2. Shingles Are Curling, Cracking, or Missing
Walk around your home and look up. If you see shingles that are curling at the edges, cracking, or missing entirely, your roof's protective barrier is compromised. In Seattle's rainy climate, even one missing shingle can lead to water damage within weeks.
3. You're Finding Granules in Your Gutters
Those tiny sand-like particles in your gutters are granules from your shingles. Some granule loss is normal on new roofs, but heavy granule loss on older roofs means the shingles are deteriorating and losing their ability to protect against UV rays and water.
4. Daylight Is Visible Through the Roof Boards
Go into your attic on a sunny day and look up. If you can see daylight through the roof boards, water can get in too. This is a serious sign that your roof deck may be compromised and needs immediate attention.
5. Your Roof Is Sagging
A sagging roof is a structural emergency. It means the decking underneath has been weakened by moisture — common in the Pacific Northwest where rain is constant. If you notice any sagging, call a professional immediately.
6. Moss Is Growing Everywhere
Moss is more than a cosmetic issue in Seattle. It holds moisture against your shingles, works its way under them, and accelerates decay. If moss has been growing for years and the shingles underneath are damaged, cleaning alone won't fix the problem — you may need a replacement.
7. Your Energy Bills Are Rising
A failing roof lets heat escape in winter and lets heat in during summer. If your energy bills have been climbing without explanation, your roof's insulation and ventilation system may be failing.
