Storm Damage Roof Repair - San Antonio Commercial Buildings

Storm damage on a commercial flat roof is rarely a single failure mode. A severe storm event produces wind uplift, hail impact, and water infiltration simultaneously - and the interaction between those forces creates damage patterns more complex than any one of them alone. The remnants of Hurricane Harvey that reached San Antonio in August and September 2017 produced sustained heavy rainfall that exposed drainage inadequacies on roofs that had never leaked under normal conditions. That combination of volume and duration put water into buildings through scuppers and drains that could not move the load, not through membrane failures.

I approach storm damage inspections as a combined-hazard event investigation. I document wind-related uplift, hail-related impact, rainfall-related ponding and infiltration, and debris-related physical damage separately - with photographs and a written narrative for each category - because the repair scope for each is different and the insurance coverage path for each may be different. Building owners who receive a single-line estimate after a storm event have no way to know what they are actually repairing.

Commercial Roofers of San Antonio operates from in downtown San Antonio. We cover Bexar County and the surrounding metro, including the areas most exposed to Hill Country storm cells - the Stone Oak corridor, the IH-10 West belt toward Boerne, and the northwestern Bexar County suburban commercial inventory along Loop 1604.
