Commercial Roofing for Cedar Hill Buildings: Flat Roofs, Membranes and Storm Risk

Cedar Hill spans parts of Dallas County and Ellis County. NOAA's Storm Prediction Center logged 115 hail reports within 10 miles of the city from 2015 through 2024, and 24 were 1.75 inches or larger. The largest stone was 5 inches, on June 12, 2023.

On a flat roof, hail does not just dent the surface. It can puncture or crack a membrane, crush insulation boards underneath and damage rooftop units. Water then spreads sideways under the membrane, so the leak inside can be far from the damage above.

Rooftop units add another risk. Condensers, ducts and curbs all sit on the membrane and are sealed into it. When hail or foot traffic damages those seals, water often enters right at the equipment, which is why we look closely at every curb and penetration.

Most flat roof problems begin with water that does not leave. Clogged drains, scuppers blocked by debris and low spots from sagging deck let rain sit on the membrane. Standing water adds weight, speeds up wear on seams and finds any small puncture. Hail makes this worse, because ice and leaves can pile up at the drains right when the most water is coming down.

Keeping drains and scuppers clear is the cheapest roof maintenance a building owner can do. Our article on flat roof drainage systems explains the main options, and a commercial roof maintenance plan shows how to schedule checks through the year.
