Solar-Reflective Shingles Cut Houston Heat—Roof Concepts Construction
What to Know About Solar-Reflective Shingles for Houston Homes
Energy-efficient shingles — sometimes called cool roof or solar-reflective shingles — reflect more of the sun’s energy than standard shingles, reducing heat transfer into the attic and lowering cooling loads. In Houston’s climate, where air conditioning runs 8 to 9 months of the year, that performance difference is real.
How Solar Reflectance Works
Standard dark asphalt shingles absorb 85 to 95 percent of solar energy. Cool roof shingles use granule technology — typically ceramic-coated granules — to reflect a higher percentage of solar radiation. Owens Corning’s Duration Cool series, CertainTeed’s Landmark Solaris, and TAMKO’s SolarMax products use this technology to achieve Energy Star ratings and reduced surface temperatures of 20 to 40 degrees Fahrenheit compared to standard shingles.
That surface temperature reduction translates into lower attic temperatures, reduced heat transfer through the ceiling into living spaces, and lower demand on your HVAC system. On a south-facing slope with direct afternoon sun exposure — common in the Houston area — the impact is measurable in energy bills.
Texas Insurance Discounts
Class 4 impact-resistant products — which overlap significantly with cool roof shingles in the Owens Corning and CertainTeed lines — qualify for insurance premium discounts in Texas. The discount varies by carrier but can run 20 to 30 percent on the wind/hail portion of your premium. For a typical Houston homeowner, that discount can offset a meaningful portion of the premium cost difference for the upgraded shingle product over time.
Solar Shingle Questions & Insurance Savings Roof Concepts Construction
When discussing shingle selection for a replacement, ask specifically about the product’s Solar Reflectance Index (SRI) and whether it qualifies for Energy Star. Ask your insurance carrier what discount is available for Class 4 impact rating.
