In 2006, some important developments occurred in the roofing industry regarding energy efficient roof membrane technology. If you have a commercial building, most likely you will be required to install a new “Cool Roof” type reflective roof that meets the standards set out in Title 24.
Cool roofs are designed to reflect ultra violent sun rays, thereby saving energy required to cool the building.
Home owners are encouraged to implement Title 24 standards, it appears that soon enough all roofs may need to comply– even residential
Typically, single ply type roofing meets the reflective roof requirements outlined in Title 24 when the white color membrane is installed. Hot tar built up roofing now has a capsheet that is reflective white and meets Title 24 Energy requirements. Asphalt composition shingle manufacturers are now producing “cool roof” shingles that appear to be muted, lighter shaded colors. You can click here to see what that type of shingle looks like installed.

A: Yes. You need to decide which Compliance Method will be used. There are only two:
A: The Envelope Component compliance method requires the use of roofing products with a minimum reflectivity value of 0.70 and minimum emissivity value of 0.75 and is the easiest way to demonstrate compliance.
The Overall Envelope compliance method allows trade-offs between various component parts of the building envelope as long as the minimum required u-factors for the specific climate zone is achieved for the wall or roof. This means that when a non-reflective roof material is used, it may still achieve compliance as long as the roof envelope achieves the u-value specified for the specific climate zone.
A: ENV-1-C and ENV-2-C. These forms are available through Submittal Builder at Cool Roof Central.
ENV-1-C is entirely job specific and is fairly simple. ENV-2-C is product specific and is partially filled out for your convenience and is available at Cool Roof Central.
