Shingle Roofing in
Seattle & Greater Area

Architectural shingles in Seattle typically last 20–30 years. Premium 50-year shingles last 30–45 years in practice due to Seattle's weather conditions. The primary threats are moss and algae growth (which can be prevented with algae-resistant shingles), and poor ventilation (which bakes shingles from the underside). Proper installation and the right material choice make the biggest difference.

Best prevention: algae-resistant shingles (GAF Timberline HDZ, Malarkey Vista AR) with copper-infused granules. Secondary options include zinc ridge strips and periodic moss treatment. Once established, moss must be treated carefully — power washing shingles off a roof shortens their life significantly. We include moss prevention recommendations in every Seattle installation.

3-tab shingles are flat, single-layer, and cheaper — but they have 20-year warranties and are more vulnerable to wind. We don't install 3-tab. Architectural (dimensional) shingles have two bonded layers that create a layered, dimensional appearance — they're heavier, wind-rated to 110–130 mph, and carry 30–50 year warranties. The cost difference is minimal given the performance improvement.

Yes — all manufacturer warranties apply across their full color and product lines. We'll bring physical samples to your estimate so you can see how different colors look against your siding, trim, and neighborhood. Lighter colors show less moss and algae staining in Seattle's climate; we can advise on what homeowners in your area tend to choose.

Standard shingle warranties cover materials only — if the shingle fails, you get new shingles but pay for labor. A system (or "enhanced") warranty covers both materials and labor for the warranty period. To qualify, all components must be from the same manufacturer (shingles, starter, ridge cap, underlayment) and installed by a certified contractor like Solomon Roof. It's the strongest protection available.
