What Every San Antonio Homeowner Should Know About Roofing
Primary Local Risk
Large hail impact damage — San Antonio sees golf-ball-sized hail multiple times per decade
Material Recommendation
Class 4 impact-resistant shingles — can reduce homeowner's insurance by 20–30% in Bexar County
Hail is the defining roofing risk in San Antonio. On April 12, 2016, a storm dropped a large swath of very large hail just north of downtown, with the biggest stone measured at 4.5 inches near Helotes, and the National Weather Service put the damage at about $1.36 billion. A storm like that can bruise or crack shingles in ways that are hard to see from the ground, so a close inspection after any hail event matters, and photos of the roof's condition taken before spring storm season make a later insurance claim easier to document. Impact resistance is worth discussing with any contractor quoting a roof replacement here.
The City of San Antonio's Development Services Department issues re-roof permits. A re-roof with no change in pitch is issued over the counter, and homeowners can apply for their own homestead; changing the pitch requires full plan review. The city's application states that a maximum of two layers of roofing is allowed under the IRC, and it requires an engineer's assessment if the slope is changing or the roof is being converted to tile. Solar panels that are removed and reinstalled need an electrical permit, and the job ends with a final building inspection. Homes in local historic districts need a Certificate of Appropriateness from the Office of Historic Preservation for exterior changes; its guidelines ask for roofing to be replaced in kind where possible, and a new metal roof can be approved administratively if the house is documented to have had one historically.
Texas does not require a state license for roofing contractors, and the Texas Department of Licensing and Regulation does not license roofers. The Roofing Contractors Association of Texas (RCAT) runs a voluntary license program with screening, an exam and yearly continuing education, and San Antonio's re-roof application asks for the contractor's City registration number. When comparing roofers in San Antonio, ask for that registration, proof of insurance and any RCAT credential, and confirm the permit will be pulled in the property owner's name, since the city notes the permit belongs to the owner.

Water Testing
Flood testing or electronic leak detection confirms the full repaired area is watertight. This step is standard for commercial work in San Antonio and required by most TX property management agreements.
