Roofing
These are the standards in SynC Standards that cover Roofing. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Membrane Roofing
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.
- Sheet Metal Flashing and Trim
Shop- and field-formed architectural sheet metal that closes the building envelope at interfaces - copings on parapets, gravel stops, fasciae and drip edges at roof edges, counterflashings over membrane base flashings, through-wall and head and sill flashings, gutters, downspouts, scuppers and conductor heads, expansion joint covers, and closure and reveal trim. Covers zinc-coated and aluminum-zinc alloy-coated steel, aluminum, stainless steel, copper, and architectural zinc; coil-applied and anodized finishes; forming, hemming, seaming, soldering, and welding; thermal movement and expansion joint provisions; wind securement of low-slope roof edges to ANSI/SPRI ES-1; fastener, cleat, sealant, and underlayment selection; and galvanic separation of dissimilar metals.
- Steel Deck
Cold-formed steel floor and roof deck furnished and installed under the Steel Deck Institute standards: composite floor deck acting with the concrete slab above it, non-composite form deck serving as a permanent form, roof deck carrying the roofing assembly, and acoustical roof deck. Covers the division of design responsibility for the deck and its diaphragm, manufacturer and installer qualification, sheet steel and metallic coating selection, the basis for profile, depth, gauge, and section properties, diaphragm design basis, attachment to supports by arc spot welds, arc seam welds, powder-actuated fasteners, and screws, side-lap fastening, the deck's role in a composite slab including shoring, concrete placement loads, and the sequence for shear studs welded through the deck, roof deck uplift attachment and FM Approval, openings and their reinforcement, pour stops, closures, and sump pans, placement and OSHA decking requirements, field cutting and coating repair, field inspection under the SDI quality standard, delivery and storage, and the warranty for the deck work.
