Flat & Low-Slope Roof Repair in Texas

Flat & Low-Slope Roof Repair: what to expect

Almost every commercial leak in Texas traces back to a detail rather than the field of the roof. Base flashing at parapet walls and HVAC curbs, pipe boots that have hardened and split, pitch pans that dried out years ago, drain clamping rings, scupper throats, and seams opened by thermal cycling account for the overwhelming majority of calls. The field membrane usually fails only where something punctured it, dropped tools, dragged equipment, foot traffic on a hot afternoon.

What a proper repair visit includes

• Locating the actual entry point, not the spot above the stain, water travels along the deck and surfaces far from the breach.
• Determining how far moisture has spread: infrared scan, moisture meter survey or core cuts.
• Removing and replacing wet insulation before the membrane is closed up.
• A repair method matched to the system, hot-air welded for TPO and PVC, adhesive and tape for EPDM, torch or cold-applied for modified bitumen.
• Photographs of the condition found and the completed repair, for your maintenance file.

When repair is the wrong answer

Repair stops making sense when the insulation is saturated across a large percentage of the roof, when the membrane has lost so much thickness or flexibility that new patches will not bond reliably, or when the same area has been patched repeatedly. At that point a restoration system or a replacement is cheaper per year of service life. Ask for the core cuts or scan results that support whichever recommendation you receive.
