The Los Angeles City Council voted on Tuesday to make "cool roof" materials mandatory on new and remodeled homes in the city, according to a report on the ThinkProgress website (see: "Los Angeles Becomes First Major City To Require 'Cool Roofs'," by Ari Phillips).

Heat-reflective roof upgrades already qualify for industry rebates and incentives in many parts of California. For a list of utility and municipal incentive programs and links, see the "Roof Rebates and Incentives" page at the website.
