About this detail

Roof assembly conditions for an equipment pad and a fall restraint penetration on a metal deck comprise a vapor retarder or barrier, rigid tapered insulation, a cover board, and a roofing membrane. The equipment pad features four and a half inches of concrete supported on a three-inch metal deck with a curb filled with rigid insulation. Waterproofing includes continuous hot-air welded PVC flashing, fluid-applied coatings, continuous edge metal, and termination bars. The fall restraint detail includes a flashing boot sealed with a collar, sealant, and a minimum eight-inch lap of roof membrane flashing up.
