State-Level Building Codes and Legislation for Roofing in Texas

Texas does not mandate a single, uniform statewide building code for all residential or commercial construction. Instead, the state legislature has adopted the International Residential Code (IRC) and the International Building Code (IBC) as the standard municipal building codes, which cities and counties may adopt and enforce. Because of this structure, specific roofing requirements are largely determined by local municipal or county ordinances, which often include local amendments to the base International Code Council (ICC) standards to address regional climate concerns such as high winds, hail, and extreme heat.

While there is no centralized state-level enforcement agency for general building codes, the Texas Department of Insurance (TDI) plays a significant role in roofing standards, particularly in designated catastrophe areas along the Texas Gulf Coast. The TDI establishes product evaluation reports and testing requirements for roofing assemblies to ensure they meet windstorm resistance standards, which are essential for properties seeking coverage through the Texas Windstorm Insurance Association (TWIA).
