As a critical part of the thermal envelope of buildings, roofing systems are subject to a wide variety of building code requirements to assure public safety and energy efficiency. For anyone starting out in the roofing business, the plethora of code requirements can be complicated and confusing.
- Does the roof need to meet UL Class A or B, and what exactly does that mean?
- What is the minimum amount of roof insulation, and is an air barrier required?
To help answer these and many more important questions, this special lesson from Dr. Jim Hoff of Commercial Roofing Boot Camp cuts through the confusion of modern commercial building codes and provides you with straightforward and understandable approach to code-compliant roofing.
The lesson starts with a brief introduction to how commercial building codes are developed in the United States and how you can determine what specific local codes affect your roofing practice. Next, the lesson provides a detailed review of the critical provisions of current building codes that involve roofing, including the key UL and FM ratings generally required to demonstrate code compliance. The lesson also provides detailed information on meeting the requirements of current energy codes, including minimum insulation levels and the use of air barriers. Finally, the lesson identifies free online resources to help you access important code information.
At the end of this free lesson, you will:
- Be able to identify what version of the model building and energy codes are currently adopted in your state or locality.
- Understand the basic requirements for roof fire and wind resistance, including important UL and FM ratings.
- Understand the basic requirements for commercial energy efficiency, including requirements for minimum insulation levels, the use of “cool” roofing membranes, and the installation of air barriers.
- Obtain a comprehensive reference list of free online codes information, including listings by codes rating agencies as well as useful energy and structural calculators to assist in code-compliant design.
