What to expect

How we repair or replace a flat roof

Roofer standing on a roof looking over the work
Step 01

Find the cause

On flat roofs it's usually a seam, a wall flashing or a drain, not the middle of the membrane.

Step 02

Repair

Small failures: re-seal seams, patch blisters, re-flash the wall.

Step 03

Replace

When the membrane is brittle, the insulation under it is wet, or it's been patched too many times: strip to the deck, replace wet boards, add tapered insulation where water ponds, install the new membrane.

FAQ

Flat roof questions

How long does a flat roof last?

It depends on the system and how well it was installed. A well-installed EPDM or TPO roof often lasts 20 years or more; patched roll roofing much less.

Can you repair my flat roof instead of replacing it?

Often, yes. Seam and wall-flashing failures are common and fixable. If the insulation underneath is soaked, a patch won't last, and we'll show you why.

Why does water sit on my flat roof?

Flat roofs should still slope slightly to a drain or edge. Sagging, settled framing or a missing taper causes ponding. We can add tapered insulation when we replace it.

Can you do the flat porch roof when you replace my main roof?

Yes. Doing both together means the joint between them is flashed once, by one crew.

Do you work on commercial buildings?

Small commercial flat roofs only, if confirmed.
