Arlington FAQ
Can I install a black asphalt-shingle roof?
Yes. Arlington has no color or reflectance restriction on residential roofing. Asphalt shingles in any color comply with current Title 6 building code, subject only to manufacturer wind-rating requirements.
Do commercial reroofs need cool membrane?
No. Commercial low-slope reroofs follow IECC prescriptive paths that allow black EPDM or modified bitumen if total roof-assembly insulation meets minimum R-values for the climate zone.
Fort Worth FAQ
Do I need a cool roof when replacing shingles on my Fort Worth home?
If the work covers more than 25 percent of the roof area or is a full replacement, IECC residential reflectivity or insulation provisions apply. Spot repairs and minor patching usually do not trigger requirements.
Can a Fort Worth commercial building skip cool roofing if it adds insulation?
Sometimes. The simulated performance compliance path lets designers trade enhanced insulation or HVAC efficiency against the prescriptive reflectance requirement, provided overall energy modeling meets or beats the IECC baseline.
