Expert Roof Deck Contractors — Custom Installation & Repair

A 20x20 deck is 400 square feet, so cost depends heavily on material choice, height, railings, stairs, roof access, structural reinforcement, and whether repair or full installation is required. Roof decks can also require waterproofing, flashing, drainage, and coordination with roofing components. Green Island Homes evaluates the site first so the estimate reflects the actual construction conditions.

A 12x24 deck totals 288 square feet, but pricing varies based on framing requirements, decking material, railing type, access, permits, and the roof or exterior structure involved.
