Texas has no statewide cool roof mandate, and Dallas County applies cool roof specifications only to its own facilities through capital project standards. Private buildings follow the Texas adopted International Energy Conservation Code without specific cool roof requirements.
Dallas County Facilities Management requires reflective Energy Star-rated roofing membranes on county building re-roof projects to reduce HVAC load. Private residential and commercial roofs follow the 2015 IECC adopted by Texas and any city amendments. Some Dallas County cities have adopted higher cool roof reflectance thresholds, but the county tier does not regulate private roofs. Solar reflective index (SRI) targets typically apply only to low-slope roofs on county buildings, not steep-slope residential roofs. Property owners pursuing cool roof rebates can check Oncor and CoServ utility programs.
Because there is no countywide private cool roof mandate, residents face no county penalties. Contractors on county projects who install non-conforming roofing may have payment withheld until compliant materials are installed.
