Flat roofs live or die by the details.

Taped seams and corners fail first if the surface isn’t primed and rolled right. We prime, tape and roll every seam.

A weld that’s too cool looks fine and peels later. We check every weld.

Around vents and curbs, flashing has to be welded, not glued. That’s where PVC roofs leak.

It only works on a dry, clean roof. We check for wet insulation first and cut out any wet areas.

Ponding water

Water still sitting two days after rain. It finds every weak seam and adds weight the deck wasn't built for.

Open or wrinkled seams

A lap you can lift with a finger, or a fishmouth wrinkle. Water gets under the membrane there.

Caulk instead of flashing

A bead of caulk around a curb or pipe. It looks sealed for a season, then it cracks.

Membrane pulled at the wall

The membrane bridges the corner instead of lying tight. One cold snap and it tears.

Clogged drains and scuppers

Leaves and debris at the drain. The whole roof's water backs up behind it.

Patches on patches

Layer after layer of repairs in one spot. The real cause underneath was never fixed.
