Light-Metal-Roof-Edge (1).pdf

This is a technical drawing specification document (DWG No. 34) for light-metal roof edge construction detail, applicable to built-up roofing (BUR) systems. The drawing provides detailed specifications for attaching metal roof edging to wall surfaces using a wood nailer fastened at 16-inch on-center intervals with continuous cleats. The installation requires a joint cover measuring 4 to 6 inches wide secured with fasteners spaced at 3-inch on-center intervals set in asphalt cement, with staggered fasteners across two rows applied before roof deck stripping. The specification mandates that all metal surfaces be primed before contact with Tremco primers, with the metal flange set in asphalt cement and prime flange dimensions ranging from a minimum of 1/2 inch to a maximum of 10 feet. The assembly includes two-ply stripping as specified, gravel surfacing, and adhesive sheet components integrated with the specified BUR membrane and insulation.

This technical specification establishes material and installation standards for light-metal roof edge systems in built-up roofing applications. The drawing serves as a reference detail for contractors and installers to ensure proper integration of metal roof edges with wall assemblies, specifying fastener patterns, spacing, and material preparation requirements. No pricing, award dates, contract terms, or bidding information is contained within this technical specification document.
