Full Breakdown
Dallas County Facilities Management requires reflective Energy Star-rated roofing membranes on county building re-roof projects to reduce HVAC load.

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.
Violations & Fines
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.
