Fremont Roof Deck Project, Seattle

Pinnacle Roofing Professionals completed this roof deck project in Fremont, Seattle, Washington. The assembly combines an 80-mil IB Roof Systems ChemGuard PVC membrane with Trex composite decking to create a waterproof, walkable outdoor deck surface over a flat or low-slope roof.

Roof Deck Assembly Components

  • IB Roof Systems 80-mil ChemGuard PVC membrane: A premium waterproofing layer designed for roof decks, patios, and balconies exposed to foot traffic.
  • Trex composite decking: A low-maintenance, wood-alternative deck surface installed over the protected membrane.

Benefits of a Waterproof Roof Deck System

  • Waterproof protection: The PVC membrane creates a seamless, watertight barrier beneath the deck.
  • Durable walking surface: Trex decking resists rot, splintering, and fading under Seattle’s wet climate.
  • Low maintenance: Composite decking and PVC membrane require minimal upkeep compared to traditional wood and built-up roof systems.
  • Added usable space: A roof deck turns an otherwise unused flat roof into outdoor living space.
