Where to Start
The best starting point is your local energy utility company. Call them, and visit their web site. Cool roof incentives are commonly found along with other energy efficiency programs and 'building envelope' programs. Then check the Cool Roof Rating Council (CRRC) rebate page. Then check with your local, county and state government. So many energy efficiency programs have been created, that finding cool roof incentives can be daunting at first. Incentives for cool roofing may be rebates, tax credits, loans, and grants.
Two Roof Types
For incentive programs, roofs are considered either low-pitched (flat) or steep-pitched (sloped). Of course, roofs are never truly flat to allow for water run-off. For steep pitched roofs where colored coatings are appropriate, a common requirement is that the roof have a three-year solar reflectance index (SRI) of 29% or more. For flat roofs, commonly coated white, an SRI of 75% or greater is typically required. ARC Cooltile IR Coatings and ARC cool white coatings meet these criteria.
Using ARC cool coatings will qualify for one Leadership in Energy and Environmental Design (LEED) point towards building certification. LEED uses ASTM standards, as verified by CRRC. LEED also references Energy Star. But for cool roof validation, Energy Star also uses the CRRC Directory. ARC products are CRRC and Energy Star rated.
All incentive granting bodies and building code writing bodies use CRRC, directly or indirectly, for qualifying a roof coating as "cool". The US EPA Energy Star program is tied to CRRC, and the US GBC LEED system is tied to CRRC. Local entities that refer to ASTM results are effectively referring to the CRRC, which validates ASTM results. If your local entity has their own list, and ARC products don't appear, please contact us. We can get them listed.
• San Francisco PG&E: 20 cents per square foot rebate for residential roofs.
• Sacramento SMUD: 10 cents per square foot rebate for steep-pitched roofs.
• San Antonio CPS Energy: 20 cents per square foot rebate for residential roofs.
In addition to incentives, many roof projects are simply required to use cool materials. For example, all roof replacements and new construction for US Department of Energy facilities must use cool roofs, as ordered in a June 1, 2010 memo from US Energy Secretary Steven Chu. In California, most roof additions, alterations and repairs for nonresidential, high-rise residential and hotels/motels are required to use cool roof products under the Title 24 Building Energy Efficiency Standards.
