This North Seattle PVC roof project is a low-slope residential roof installed by Pinnacle Roofing Professionals. The home had a 2×6 car-decking open-beam ceiling, so the crew built up the roof assembly with 6 inches of poly-ISO insulation board and finished it with a durable 80 mil IB PVC membrane in red.
