Why Flat Roofs Fail Faster in Houston
Houston's subtropical climate brings hot humid summers that bake modified bitumen and TPO seams. Mild winters keep moisture trapped under the membrane instead of letting it dry out. In neighborhoods like the Heights and Midtown, older flat roofs often sit behind parapet walls that trap leaves and hold water after heavy rain.
Common Failure Points We See Daily
Cheap contractors skip proper flashing at HVAC curbs and scuppers. That leads to rot in the wood deck on many River Oaks and Montrose homes. We always check the drain sumps first because clogged drains cause 60 percent of the flat-roof calls we get in Downtown and near Minute Maid Park.
Materials That Hold Up Here
We use 60-mil reinforced TPO or 90-mil EPDM with heat-welded seams for most repairs. These hold better against UV and standing water than the 45-mil sheets some crews install. Harris County permits are required on any tear-off over 100 squares, and inspectors check seam strength on commercial jobs.
