Dallas FAQ
Do I need a cool roof when replacing shingles on my Dallas home?
If the work covers more than 25 percent of the roof area or is a full replacement, the IECC residential reflectivity or insulation provisions apply. Spot repairs and minor patching usually do not trigger the requirement.
Can a Dallas commercial building skip cool-roofing if it adds insulation?
Yes, sometimes. The simulated performance path lets designers trade enhanced insulation or HVAC efficiency against the prescriptive reflectance requirement, provided overall energy modeling meets or beats the baseline IECC compliance threshold.
DeSoto FAQ
Do I need a cool roof for my Dallas County home?
No. There is no countywide cool roof requirement for private homes. Check your city's energy code amendments for any reflectivity rules that may apply locally.
Are there rebates for installing a cool roof?
Yes. Oncor Take A Load Off Texas and some retail electric provider programs offer commercial cool roof rebates. Residential incentives are limited but can include attic radiant barrier rebates.
