Flat roof repair stops the leak that shows up as a ceiling stain three days after a nor'easter. In Trenton, that usually means water has been ponding at the seams for a while.
We run a roof asset survey first, then decide whether the membrane needs a repair coat, a recover, or a full tear-off. Property managers get a written line-item estimate before any dumpster shows up.
TPO and PVC single-ply hold up on a hot rooftop, while EPDM and modified bitumen handle the freeze-thaw that follows a January ice dam. We install systems from Carlisle SynTec, Firestone, GAF EverGuard, Johns Manville, and Versico.
A reflective coating over an existing built-up roof can add years for a fraction of replacement cost, but only when the substrate is dry. If the decking has rotted, coating it wastes your money.
- TPO membrane is heat-welded at every seam and reflects summer sun, which keeps the space below cooler and the air conditioning load lower.
- EPDM is a rubber single-ply that stretches through the freeze-thaw cycles that follow a hard Trenton winter.
- Modified bitumen comes in torch-applied and self-adhered rolls, useful on the packed rowhomes where an open torch near a parapet is not safe.
- Built-up roofing layers felt and asphalt, and it can be recoated instead of torn off when the plies are still sound.
- PVC single-ply resists the grease and standing water you find around exhaust fans and scuppers on commercial rooftops.
