When people think about storm damage, they picture missing shingles on homes. Commercial roofing systems face a different set of risks during spring storm season.

Flat and low-slope roofs respond very differently to wind, hail, and heavy rain.

Wind Uplift Is a Major Threat

Commercial roofs rely on secure membrane attachment systems. During high winds, pressure changes can cause uplift. Even a small section of loose membrane can allow water to travel underneath the system. Unlike residential roofs, water may not immediately show inside. It can move laterally across insulation and decking before appearing far from the original breach.

Ponding Water Accelerates Damage

Spring storms often dump large volumes of rain in short periods. If drains are partially clogged or slopes are insufficient, water can pond on flat roofs. Standing water stresses seams, flashing details, and penetrations. Over time, that leads to membrane deterioration and hidden moisture within insulation layers.

Hail Impacts Vary by System Type

Not all commercial systems react to hail the same way. TPO, modified bitumen, and metal roofing each show damage differently. Some impacts are cosmetic. Others compromise the membrane and shorten the lifespan of the system. Post-storm inspections are critical because damage is not always obvious from the ground. 

Spring storms are predictable. Their timing is not. Proactive inspections and maintenance are the difference between controlled repairs and operational disruption. Call Tri Tex at 512-583-0500 to help protect your property and prevent costly disruptions.
