Texas Has No Statewide Roofing License — What This Means for You
Unlike electricians and plumbers, roofing contractors in Texas are not regulated by the state. The Texas Department of Licensing and Regulation (TDLR) does not license, register, or set minimum insurance requirements for roofers. This means anyone can legally solicit roofing work in San Antonio without training, insurance, or any formal qualifications. After major hailstorms, out-of-state and unlicensed “storm chasers” routinely flood the market in San Antonio. The practical protections available to homeowners are: (1) verifying RCAT (Roofing Contractors Association of Texas) licensure at rcat.net; (2) confirming City of San Antonio Home Improvement Contractor registration; (3) checking BBB accreditation at bbb.org; and (4) verifying manufacturer certifications directly with GAF, Owens Corning, or CertainTeed.
City of San Antonio Permit Requirements
The City of San Antonio’s Development Services Department (DSD) requires a permit for all roof replacements and re-roofing projects. For a standard reroof with no change in roof pitch, the permit application can be submitted with proof of ownership and is typically approved same-day or over-the-counter. Complex reroofs involving a change of roof pitch require a plan review process taking approximately three business days. Contractors must be registered as Home Improvement Contractors with the City of San Antonio DSD before any permits are issued — this registration requires an FBI criminal background check, proof of liability insurance ($300,000 per occurrence / $600,000 aggregate minimum), and a $150 fee valid for two years. Work without a permit may result in citations of $300–$1,000 and a Stop Work Order. Contact DSD at (210) 207-1111.
RCAT Voluntary Licensing Program
The Roofing Contractors Association of Texas (RCAT) administers a voluntary Licensed Roofing Contractor program that serves as the closest equivalent to a state roofing license in Texas. RCAT requires contractor principals to have a minimum of 2 continuous years of Texas-based roofing experience, a fixed business address, current general liability insurance ($300,000 residential / $500,000 commercial), workers’ compensation coverage or a filed exemption, and to pass written exams in business/safety and roofing (70% minimum score). Licensees must complete 8 continuing education units annually for renewal. Because the program is voluntary, contractors who hold RCAT licensure are demonstrating professional standards that the state does not require. Verify any contractor’s RCAT status at rcat.net/consumers.html or call RCAT at (800) 997-6631.
San Antonio’s Climate & Hail Risk
San Antonio sits in the heart of “Hail Alley,” with more than 136 documented hail events recorded within 10 miles of the city center and Texas leading all states in hail-damage insurance claims. Summer temperatures routinely exceed 100°F, with UV radiation sufficient to degrade standard asphalt shingles 30–40% faster than in northern climates — a 30-year shingle may reach end of life in 15–18 years in San Antonio. The city also experiences periodic high-wind events and rare but damaging winter freezes. For these reasons, Class 4 impact-resistant shingles (UL 2218 rated) are strongly recommended; many Texas insurers offer premium discounts of 15–35% for Class 4 installations. Stone-coated metal roofing (DECRA, Gerard, or similar) provides the highest hail protection at a premium price point. Verify any insurance discount eligibility at tdi.texas.gov.
Windstorm Insurance & TWIA
San Antonio (Bexar County) is not within the Texas Windstorm Insurance Association (TWIA) designated First Tier coastal counties. San Antonio homeowners obtain wind and hail coverage through standard private insurance, not TWIA. The WPI-8 Certificate of Compliance required for TWIA eligibility is not applicable for Bexar County properties. However, San Antonio contractors who also serve the Texas Gulf Coast (Corpus Christi, Rockport, Port Aransas, and the Rio Grande Valley) should be TDI-certified windstorm contractors for that work. Bison Roofing’s Rio Grande Valley office and Stephens Roofing’s Victoria operations make TDI windstorm competence relevant for those specific contractors. For properties in the 14 TWIA First Tier counties, contact TDI at (800) 248-6032.
Best Roofing Materials for San Antonio
Asphalt shingles (Class 4 impact-resistant): The most common and cost-effective choice. Specify UL 2218 Class 4 rated products (e.g., GAF Timberline HDZ, Owens Corning Duration STORM, CertainTeed Landmark IR) for maximum hail resistance and potential insurance discounts. Standard 3-tab shingles are not recommended for San Antonio’s climate. Stone-coated steel: Premium Class 4 impact-resistant option; 40–70 year lifespan; up to 70% solar reflectivity reduces cooling costs; ideal for homeowners wanting maximum hail and UV protection. Standing seam metal: Excellent for both residential and commercial applications; wind-resistant; long lifespan; increasingly popular in San Antonio’s Hill Country-adjacent neighborhoods. Clay or concrete tile: Traditional material well-suited to San Antonio’s Spanish Colonial architecture; 50+ year lifespan; excellent thermal mass; requires structural verification for heavier concrete tile. TPO / EPDM / Modified Bitumen: Standard for flat commercial roofs; TPO preferred for UV resistance and energy efficiency in San Antonio’s high-heat environment.
