Composite Rooftop Deck Over a Flat Roof in Ashtabula

In 2025, we built a 26 by 14 composite rooftop deck over the flat roof above a kitchen in Ashtabula, near the lake. The deck framing is freestanding rather than fastened through the existing roof.
We protected the roof with a membrane safe slip sheet and arranged adjustable pedestals in a grid. Pressure treated 2x6 joists support Trex Enhance composite decking installed with hidden fasteners, with white composite fascia and white railings finishing the deck.
