Roofing Services in San Antonio, TX

San Antonio anchors the southern end of the Texas hail corridor, and while the city sees fewer hail days per year than DFW, the events it does get are unusually large and unusually concentrated — April 2016 produced 4.5-inch stones over a densely populated area and May 2025 delivered three-inch hail on the northwest side. The heaviest cores repeatedly favor the north and northwest, from Helotes and Leon Valley through Castle Hills toward the airport. Between storms, sustained 100-degree summers cook asphalt, and the occasional hard freeze cycles brittle clay tile and old metal seams.

Texas issues no statewide roofing contractor license, and RCAT certification is voluntary — so verifying who you hire is entirely on the property owner. Inside city limits, the San Antonio Development Services Department requires a permit for a residential re-roof, issued over the counter when the pitch is unchanged and subject to full plan review when the pitch changes or you convert to tile; contractors must be registered with the city, and the IRC limit of two roofing layers applies. Work in a locally designated historic district also runs through the Office of Historic Preservation for a Certificate of Appropriateness, and addresses in unincorporated Bexar County or enclave cities like Alamo Heights and Olmos Park answer to a different authority — confirm which one covers your address before tear-off. Texas Insurance Code Chapter 707 makes it illegal for a contractor to waive or absorb your deductible.
