Waterproof PVC membrane roofing for flat and low-slope roofs. Ideal for Seattle's rain. 20-30 year lifespan, energy-efficient, virtually maintenance-free.
Flat and low-slope roofs need specialized waterproofing. PVC membrane creates a completely waterproof barrier with heat-welded seams stronger than the membrane itself. It's the gold standard for flat roofs in Seattle's rainy climate.
Roof4Life has installed hundreds of PVC systems across Seattle, Bellevue, Kirkland, and the Eastside on residential additions, commercial buildings, and rooftop decks.

Heat-welded seams, superior chemical resistance, 20-30 year lifespan. Best for Seattle's wet climate.
Similar to PVC, slightly less expensive. Good performance, 15-25 year lifespan. Solid budget alternative.
Older technology with glued seams that can fail in wet climates. 15-20 year lifespan. We recommend PVC or TPO over EPDM.
