Why it happens

Why rowhome flat roofs leak: it starts where water sits

A flat roof drains slowly by design, so water lingers and finds the weak points first: aged seams, the flashing where the roof meets a parapet wall, and low spots that pond after every storm. Our full guide breaks down each cause, then walks through repair versus replacement.

What we handle

Four ways to deal with a leaking flat roof

The right move depends on how much of the roof has failed. Here is what each one solves. The guide goes deeper on how to choose.

Flat Roof Repair

Finding and fixing the failure that is letting water in, from a single seam to the flashing at a parapet wall.

Best for: leaks at seams, flashing, or a ponding spot

EPDM & Rubber Roof Repair

Patching seams, punctures, and flashing on EPDM and other rubber membranes, or recoating one near end of life.

Best for: a rubber membrane splitting or pulling at the seams

Emergency Roof Leak Repair

Fast tarping and temporary sealing to stop the water, then a proper repair once the roof is dry.

Best for: water coming through the ceiling right now

Replacement & Coating

A full membrane replacement when repairs stop holding, or a coating to buy added years on a sound roof.

Best for: a roof past patching, or one to extend a few years

What it costs

What goes into the price

Every roof is different, so there is no one-size price. A small seam or flashing repair is inexpensive; a coating or full replacement is a bigger project. The main things that move the number:

  • Which fix you need. A small seam or flashing repair is a fraction of the cost of a coating, and a coating is a fraction of a full tear-off and replacement.
  • Roof size and access. Rowhome roofs are small, but access through a hatch or over a parapet, and tight blocks with no driveway, all add labor.
  • Membrane type. EPDM (rubber), modified bitumen, and TPO each repair and replace differently, and matching the existing system matters.
  • Hidden damage underneath. Water that has been getting in for a while can rot the decking or soak the insulation, which is not visible until the old roof comes up.
