At the beginning of 2015, the City of Los Angeles began enforcing ordinance number 183149 of the Los Angeles Municipal Code which applies to the construction of every new building, every new building alteration with a building permit valuation of $200,000 or more, and every building addition throughout the City of Los Angeles. Specifically, the City of LA is attemtping to reduce the heat island effect within the city, while lowering overall energy consumption (i.e. AC use). This code applies to both residential and commercial properties and is an aggressive, yet necessary approach to meeting California’s Title 24 cool roof requirements.
The Los Angeles Green Building Code requires that your new roofing material in residential buildings meet the following SRI (solar reflectance index) values:
There are a few exceptions to the above requirements:
Los Angeles Department of Water and Power (LADWP) cool roof rebates are available to single-family and multifamily residential customers. The base rebate is $0.20 per square foot for qualifying roofs.* For more information, visit: www.ladwp.com/rebatesandprograms
*Funding is limited and rebates are not guaranteed. The program is subject to change or termination without notice.
Considering that the vast majority of residential roofs in Los Angeles are composition shingle roofs, our friends at GAF have put together the following list of shingles that meet both the Los Angeles Green Building Code and Title 24, and are also listed with the Cool Roof Rating Council (CRRC).
