Choosing the Right Roof for Washington Weather
The Pacific Northwest presents unique challenges for roofing: over 37 inches of rain per year in Seattle, frequent wind events, and a climate that encourages moss and algae growth. Choosing the right material can mean the difference between a roof that lasts 15 years and one that lasts 50+.
Here's how the most popular roofing materials perform in our climate:
GAF Timberline HDZ Architectural Shingles
Best for: Most residential homes in the Puget Sound area
GAF Timberline HDZ is the most popular residential roofing material in the Seattle area — and for good reason. These architectural shingles offer:
- Wind resistance up to 130 MPH — critical for Pacific Northwest storms
- Algae-resistant technology — StainGuard Plus prevents black streaks from our humid climate
- Lifetime limited warranty from GAF
- Excellent value — the best balance of performance and affordability
As a GAF certified contractor, we install Timberline HDZ with the full system of underlayment, starter strips, and ridge caps for maximum protection.
Metal Roofing (Standing Seam)
Best for: Homeowners who want maximum durability and modern aesthetics
Metal roofing is growing in popularity across the Pacific Northwest because it excels in our climate:
- 50+ year lifespan — you may never need another roof
- Moss and algae resistant — smooth surface prevents growth
- Excellent in heavy rain — water sheets off instantly
- Energy efficient — reflects solar heat in summer
- Higher upfront cost but lower lifetime cost
