10-0508 (RR) Title 24Manufacturers are required to submit samples to certified labs to be measured. The emissivity and reflectivity
values are measured using ASTM standards.
The results are reported to CRRC (Cool Roof Rating Council). Samples are sent to the CRRC-approved test farm
for three years in order to evaluate aged results which will eventually be on the CRRC website together with the
initial results. Note: CRRC is an independent and non -biased organization that has established a system for
providing building code bodies, energy service providers, architects, specifiers, property owners, and community
planners with accurate data on reflective roof surfaces. This information helps to improve the energy efficiency of
buildings, while positively impacting our environment.
The chart below lists Title 24 compliant GAF products for both low -slope and steep -slope roofing.

California Title 24
Part 6
Sell Sheet
Updated: 12/09
Quality You Can Trust Since 1886.. .
From North America s Largest Roofing Manufacturer
Title 24 is intended to maximize energy efficiency by regulating many aspects of building constriction.
The Title 24 Energy Budget is set for residential and non-residential buildings. It varies by climate zone
(there are 16 in California) and is defined in Kbtu/sq foot per year.
Compliance can be complicated, so the information on the reverse side is meant to help you understand some
basic information and how GAF Materials Corporation roofing products can help you comply.
There are multiple compliance methods. One of them, the envelope compliance method, requires the use of cool
roof membranes. For low -slope buildings, a cool roof must have a minimum 3 -year aged reflectivity value of 0.55
with a minimum emissivity value of 0.75 or a minimum aged solar reflectance index (SRI) of 64 to be compliant.
In addition, increasing roofing insulation R -value with
EnergyGuard— Insulation products will also help you achieve
compliance. GardenScapes— vegetated roofing systems are
also compliant since the California Energy Commission
considers vegetated roofs as a roof with thermal mass on it.
Effective 1/1/2010: Title 24 guidelines will also apply to
steep -slope products.
Non-residential, steep -sloped roofs with roofing products < 5 lbs
per square foot (asphalt shingles) shall have a minimum 3 -year
aged reflectivity value of 0.20 and a minimum emissivity value
of 0.75, or a minimum aged solar reflectance index (SRI) of 16.
Steep -sloped roofs with roofing products > 5 lbs. per square foot
(TruSlate" Genuine Slate Roofing) shall have a minimum 3 -year
aged reflectivity value of 0.15 and a minimum emissivity value
of 0.75, or a minimum aged solar reflectance index (SRI) of 10.
