What is different about flat roof replacement in Texas

Texas has no statewide contractor licensing for general residential work, so verifying trade licenses and insurance matters more here than in almost any other state.

Owner-builder: Owner-builder permits allowed on owner-occupied property. Flat Roof Replacement generally requires a licensed contractor to pull the permit, even where owner-builder status is available.
