Tips for Successful Specifications

  • Specify roof curbs in section 07720. (Include a footnote in the Mechanical and Skylight sections that reads, “all roof curbs are specified in 07720.”)

  • Curb installation should be a part of the roof deck, not on top of insulation or roofing materials.

  • Curbs should be a minimum of eight inches above the finished roof and factory-insulated to reduce condensation.

  • Pressure-treated nailers should be provided by the curb manufacturer to receive roofing felts and eliminate noise transfer.

  • Curbs should be sloped to avert water ponding.

  • Structural roof curbs can be factory-designed and manufactured using a wide range of materials and weights, and with many options, such as burglar bars.
