Flashing-for-Non-Wall-Supported (1).pdf

This is a technical drawing specification document for built-up roof hot/cold wall flashing designed for non-wall-supported deck applications. The drawing, designated as DWG NO. 11 and prepared in 2023, provides detailed construction specifications for a roofing assembly including a specified built-up roof (BUR) membrane with two-ply fasteners spaced at eight-inch on-center intervals. The specification calls for a one-piece counterflashing, specified sealant, and gravel surfacing installed into a reglet and secured with lead wedges at eight-inch intervals. The assembly incorporates flexible vapor retarder insulation, wood nailers secured to the deck with appropriate fasteners in two rows staggered at twenty-four-inch on-center spacing, stripping with specified base flashing rows at twelve-inch on-center spacing with staggered blocking in two rows, and wood cant nailed to sheet. The drawing is presented at a not-to-scale (NTS) ratio and indicates a minimum four-inch clearance requirement for the flashing configuration.
