Leak repair

Parapet and wall flashing

The parapet is where more commercial leaks originate than anywhere except seams. The membrane turns up the wall, is terminated mechanically, and is capped — and every one of those three can fail independently. Coping joints open, counter-flashing pulls out of its reglet, and the termination bar loosens as the building moves. Water entering here often tracks a considerable distance before showing inside, which is why parapet leaks are frequently misdiagnosed.

What the job involves

  • Inspection of upstand, termination bar, counter-flashing and coping
  • Coping joint and cap condition assessment
  • Reglet repair where counter-flashing has pulled free
  • Through-wall flashing check where staining suggests wall ingress
  • Repair that reinstates the detail rather than sealing over it

Signs you need it

  • Staining down the inside face of an external wall
  • Visible gaps at coping joints
  • Membrane upstand sagging or pulled away from the wall

Questions

The leak shows well away from the wall. Can it still be the parapet?

Routinely. Water entering at a parapet runs between membrane and insulation, or along the deck, and surfaces at the first penetration or low point it reaches. Parapet leaks presenting in the middle of a tenant space are very common and very often misdiagnosed.

Can coping joints just be sealed?

Sealant buys a year or two at most on a joint that moves with the building. Where a coping is the entry point, the durable fix is a proper cover plate or a redesigned joint — sealant alone is a maintenance commitment, not a repair.

Describe what you are seeing

Low-slope roofs in this climate fail at details rather than in the field, and the damage is usually well advanced before water reaches a tenant space.
