Consumer considerations for purchasing SR roofing
Solar reflectance (SR) or albedo is the ability of a surface material to reflect incident solar (short wave) radiation
Expressed on a scale of 0 to 1Total solar absorption (SR = 0.0)
Total solar reflectance (SR = 1.0)
In general, light-colored surfaces have higher solar reflectance than dark
What is Solar Reflectance?
Thermal emissivity (TE) is the amount of thermal radiation (infrared or long wave radiation) that radiates thermal energy (heat) away from its surface
Expressed on a scale of 0 to 1Total thermal absorption (TE = 0.0)
Total thermal emissivity (TE = 1.0)
Most roofing materials, except metals, have thermal emissivity values above 0.85

Energy Star® Rated Roof Product Features
Reflect more of the sun’s energy back into the atmosphere using high solar reflectance coatings or pigments
Release more absorbed heat back into the atmosphere using high thermal emissive coatings or pigments
Keep building’s cooler by reducing roof surface temperature
Reduce the amount of energy needed to cool buildings in warmer months
Help to reduce the production of air pollutants from electricity generation
Benefits of Cool Roofs (Source EPA)
Potential for lower utility bills due to energy savings
Downsized A/C equipmentA reflective roof can reduced peak cooling demand by 10% to 15% which, may lead to the purchase of smaller, less expensive cooling systems
Extended roof life through surface thermal shock reductionReducing the expansion and contraction that occurs due to heating and cooling of the roof surface during the day
Potential for improved urban air qualityDecreased levels of pollution though reduced air temperature and cooling demand
Reduce Urban Heat Island Impact
Heat released at night causing air temperatures to remain high
Urban and suburban areas are typically 2 to 10 ˚F hotter than surrounding rural areas
Source: US EPA
Impact of Elevated Temperatures
Increased demand for air conditioningParticularly during peak demand times
Increased fuel use for vehicle air conditioning
Increased smog levelsOzone, smog and acid rain which contribute to global climate change
Increased health problems related to heat and poor air quality
Impact of the American Recovery and Reinvestment Act of 2009
Federal Tax Credits for Energy Efficiency Home Improvements
All Energy Star labeled asphalt roofs qualifyRoofing products must be expected to last 5 years or have a 2 year warrantyEffective for 2009 and 2010Tax credit is 30% of costMaximum tax credit per homeowner for all home improvements is $1500 for 2009 and 2010
Homeowner must save receipts and submit a Manufacturer Certification Statement
IRS Tax Form 5695 (2009 version)
Quick Energy Savings EstimatesBased on Seasonal Electric Bills
15 to 25 percent of the total cooling load cost for a house is due to the ceiling heat gain through the roof
Landmark Solaris Shingles can reduce the cooling load between 10 and 15 percent
Seasonal cooling cost ($) multiplied by the cooling load reduction (%), multiplied by the ceiling heat gain range (15% - 25%)
