Why South San Antonio Homes Are More Susceptible to Wind Damage During Squall Lines

South San Antonio homeowners face unique wind damage risks during squall line storms that sweep across the region each spring and fall.

Material upgrades provide the best long-term protection. Class 4 impact-resistant shingles, enhanced underlayment systems, and upgraded flashing materials all increase wind resistance. While these upgrades require upfront investment, they often pay for themselves through reduced repair costs.
