title: Membrane Roofing
category: Building Envelope
description: >
When to use: Roof systems in which a flexible sheet membrane forms the primary weather barrier, together with the insulation, cover board, vapor retarder, attachment, flashings, and terminations that make the membrane work. Covers thermoplastic sheet (TPO, PVC, KEE), thermoset sheet (EPDM), and polymer-modified bitumen sheet (SBS, APP) membranes; mechanically attached, induction-welded, adhered, self-adhered, torch-applied, hot-mopped, cold-adhesive, and ballasted attachment; new construction, tear-off replacement, recover, and partial replacement; wind uplift and fire design basis, field seaming, flashing and termination detailing, field testing, and warranty.
− Not intended for: Fluid-applied membranes and coating restoration systems ([[sync/fluid-applied-roofing]]); sprayed polyurethane foam roofing; vegetative roof assemblies and their overburden ([[sync/vegetated-roofing]]); discontinuous steep-slope roof coverings such as shingles, tile, slate, and standing-seam panels ([[sync/asphalt-shingle-roofing]], [[sync/metal-roof-panels]]); below-grade and plaza-deck waterproofing ([[sync/below-grade-waterproofing]], [[sync/self-adhering-sheet-waterproofing]]); roof drain, leader, and storm piping sizing and routing ([[sync/roof-drainage]]); architectural sheet metal fabrication and roof specialties beyond their interface with the membrane ([[sync/sheet-metal-flashing-and-trim]], [[sync/roof-specialties-and-copings]]); structural design of the roof deck ([[sync/steel-deck]]).
