SynC · Topic
These are the standards in the SynC Standards library that cover Roof Drains. 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 — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 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.
Roof drainage systems on and within the building, including primary roof drains, the required secondary (overflow) drainage by overflow roof drains or overflow scuppers, vertical rainwater leaders and conductors, and horizontal storm drainage piping within the building from each roof drain to the point of connection with the site storm drainage system. Covers rainfall-rate-based sizing, drain types (roof, overflow, deck, balcony, planter, and area drains), controlled-flow roof drainage, drain bodies with domes and strainers, flashing- and membrane-clamp integration with the roofing, piping materials, joining, hangers and supports, expansion provisions, and condensation insulation of conductors. Applicable to commercial, institutional, and industrial buildings with low-slope and steep-slope roofs.
