Key Warning Signs Homeowners in King, Pierce, Kitsap & Thurston Counties Should Watch For
Your roof is one of your home’s most important defenses against Pacific Northwest weather, especially with our heavy rainfall & moss growth. But over time, even the best-built roofs start showing signs of wear. Knowing when to replace your roof can prevent costly water damage, energy loss, and structural issues.
If you live in King, Pierce, South King, Kitsap, or Thurston County, here are the key warning signs to watch for.
1. Curling or Buckling Shingles
When shingles start to curl, buckle, or lift, they’re no longer sealing properly against wind and moisture.
In the PNW, where damp conditions are common, this can lead to water seeping underneath and rotting the roof deck. Curling often happens with aging asphalt shingles or due to poor attic ventilation.
Pro Tip: If more than 25% of your roof is curling, a full replacement may be more cost-effective than spot repairs.
2. Leaks and Water Stains
Have you noticed water spots on ceilings, stains in your attic, or drips during rainstorms? These are clear signs your roof is failing to keep water out.
Even a small leak can lead to mold, insulation damage, and structural rot; all expensive problems if ignored.
Ampro Builders can perform a free inspection to identify leaks and determine whether repair or replacement is best.
3. Granule Loss on Shingles
Check your gutters! If you find black, sand-like granules, your shingles are wearing out.
Granules protect shingles from UV rays and weathering, so losing them means your roof is aging and less resistant to moisture.
Most shingles start showing granule loss after 15–20 years, depending on material quality.
4. Sagging Roof Deck
A sagging roofline is a serious red flag.
It could indicate trapped moisture, rotted decking, or structural failure; all of which require immediate attention.
If you notice dips or uneven areas, call a licensed roofing professional right away.
5. Moss, Algae, and Mold Growth
In our damp Pacific Northwest climate, moss and algae thrive.
While a little moss might seem harmless, it holds moisture against your shingles and causes premature deterioration.
If moss has taken over, it’s often a sign the shingles are past their prime.
Professional cleaning can help, but if moss has caused lifting or cracking, replacement is the best option.
6. Age of Your Roof
Most asphalt shingle roofs last 20–25 years, while metal or tile can last longer.
If your roof is approaching the 20-year mark, especially if it’s showing any of the above symptoms, it’s time to plan for replacement.
Why Timely Replacement Matters
Delaying roof replacement can lead to:
- Interior water damage and mold
- Decreased home value
- Higher energy bills
- Costly structural repairs
