Coastal-climate roofing in Seattle

•Rainy season: October–March. Salt air + constant moisture accelerate corrosion on exposed fasteners — galvanized steel is insufficient.
•Marine-grade aluminum or copper flashing lasts 3–5× longer than standard steel in coastal installs.
•Moss and algae growth are aggressive — zinc strips or algae-resistant shingle lines (3M Scotchgard, GAF StainGuard Plus) extend useful life 5–10 years.
•Flat + low-slope roofs in Seattle need TPO or EPDM with heat-welded seams; overlap repairs fail within 3–5 years in this climate.
