THE TILE ROOFING ENERGY COST SAVINGS (TRECS) STUDY)In 2024, the Tile Roofing Industry Alliance launched a multi-year Tile Roofing Energy Cost Savings (TRECS) Study in partnership with the U.S. Department of Energy to validate the superior energy benefits of concrete and clay tile roofing versus common asphalt shingles.

The Issue: Proving the inherent energy advantage of tile roofing over other steep-slope roofing products.
What We Know: Attic temperatures are lower under tile roofs. This Means That:
|
What The Industry Thinks: All roofing products with the same reflectivity values save the same.

The Solution: The Tile Roofing Energy Cost Savings (TRECS) Study.
Our study is paving the way to a new understanding for savings by:
Our study is paving the way to a new understanding for savings by:
- Conducting new research that has never previously been performed using real-world performance data
- Measuring temperatures:
- At the roof deck
- In the attic space
- Air-conditioned space
- Providing three years of actual field performance.
- Quantifying and validating the the actual energy usage reduction under a tile roof.
- After three years, Oak Ridge National Labs will review and certify the results.

How Do We Test?
10 Code Defined Climate Locations: Climate Zone 1 (Hot Humid) South Florida Climate Zone 2 (Warm Humid) Orlando, Florida Climate Zone 3 (Warm Dry) Phoenix, Arizona Climate Zone 4 (Dry) Rialto, California Climate Zone 5 (Warm Humid) Fort Worth, Texas Climate Zone 6 (Marine Dry) Portland, Oregon Climate Zone 7 (Marine Moist) Marian, Virginia Climate Zone 8 (Dry) Reno, Nevada Climate Zone 9 (Moist) New Lexington, Ohio Climate Zone 10 (Cold Dry) Wisconsin |

What Does The Data Show?
The surface temperatures are registering differences between tile and shingles of up to 50 degrees Fahrenheit.
|
The attic temperatures are registering differences between tile and shingles of up to 30 degrees Fahrenheit.
