Dallas City Code Chapter 53 amends the International Energy Conservation Code to require cool roofing on most low-slope commercial roofs and to set higher reflectivity standards on residential roofs. The amendment supports the Climate Action and Equity Plan goal of reducing urban heat island effects.
Dallas Chapter 53 building code amendments incorporate enhanced cool-roof provisions for new construction, reroofing, and major alterations. Low-slope commercial roofs generally must use roofing materials with a minimum three-year aged solar reflectance index meeting prescriptive Section C402 thresholds, or comply through alternative ENERGY STAR or Cool Roof Rating Council certified products. Residential steep-slope roofs must meet IECC Section R402 prescriptive insulation and reflectivity options or use the simulated performance compliance path. Local amendments tighten certain values to reflect Dallas climate zone 3A conditions and CECAP heat-island goals. Permits are issued through the Department of Development Services, and inspectors verify product certifications during roof-cover inspections. Reroof projects affecting more than 25 percent of roof area trigger compliance.
Failure to install compliant reflective roofing can lead to permit denial, stop-work orders, and required tear-off and replacement. Dallas Code Chapter 53 violations carry fines up to $2,000 per day per offense for repeat or hazardous violations.
