This project involves replacing an existing roof of approximately 114 squares using lightweight Class A or B roofing materials installed over solid sheathing. Class A materials are required in areas designated as Very High Fire Hazard Severity Zones to ensure fire safety. Residential roof replacements exceeding 50% of the total roof area must incorporate cool roof products certified by the Cool Roof Rating Council to enhance energy efficiency. Non-residential buildings may also require cool roof installations in accordance with Title 24 energy regulations. All work must adhere to relevant fire safety and energy efficiency codes.

Project details

Perform roof replacement using Class A or Class B roof covering materials that weigh less than 6 pounds per square foot, installed over existing solid sheathing. The total roof area to be replaced is approximately 114 squares. For properties located within a Very High Fire Hazard Severity Zone (VHFHSZ), the use of Class A roof covering materials is mandatory to meet fire safety regulations. For residential roof replacements where more than 50% of the total roof area is being replaced, apply a cool roof product that is labeled and certified by the Cool Roof Rating Council (CRRC) to improve energy efficiency and reduce heat absorption. For non-residential buildings, compliance with Title 24, Part 6, Section 141.0(b)2b may require the installation of a cool roof product as well. All materials and installation methods must comply with applicable fire safety and energy efficiency standards.
