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.




We have the expertise, experience and resources to undertake the architectural needs of projects large and small from throughout the entire United States of America.


The quality of our systems are the very reason we exist. It is just as important today as it was when we started that our roof curbs be designed to withstand the elements.


Our focus is always on achieving the very highest levels of customer service and we go to great lengths to ensure our clients receive a prompt, friendly and efficient service.
