Felt Roof Repair Cost

Felt repairs are cheap when the deck is dry and a waste of money when it is not, and the whole skill is telling the difference before you spend anything. We lift a corner, we look, and then we tell you which of the two jobs you are actually buying.

  • Patch weld to sound three layer torch on felt, low cost, quick
  • Blister and split repair with the same membrane family
  • Deck checked before any patch is recommended
  • Ponding water treated as a symptom, not a cosmetic issue
  • Replacement options in GRP, EPDM or new torch on felt

When a patch is genuinely the right call

Modern SBS modified torch on felt is repairable by design. A mechanical split, a nail pop, or a lifted lap on an otherwise sound roof welds back and gives you years. If the surface is still flexible, the mineral is largely intact and the deck feels firm underfoot, patch it and keep your money.

When a patch is throwing money away

Widespread blistering, brittle cracking across the field, standing water that never clears, and a deck that gives underfoot all say the same thing. The felt has done its time and the ply below is holding moisture. Patching that is a twelve month reprieve at best.

What replacement looks like

Strip to deck, replace wet boarding, then either a three layer torch on system, a one piece EPDM, or a GRP laminate depending on the shape, the falls and how long you plan to own the building. Shallow falls favour felt, simple rectangles favour EPDM, and heavy foot traffic favours GRP.

Felt roof repairs, common questions

Why does my flat roof only leak in heavy rain?+

Usually a lap or a detail that is watertight under light rain and overwhelmed when the volume rises, or standing water finding a pinhole once the pond gets deep enough. Both point at the detail rather than the whole field.

Is ponding water a problem?+

It is the clearest early warning you get. Standing water accelerates UV and freeze damage and tells you the falls are wrong. It rarely leaks on its own, and it reliably shortens the life of everything under it.

Can you re-cover over the old felt?+

Only where the existing is dry, well bonded and sound. Most of the time it is not, and overlaying a wet deck traps moisture between two waterproof layers, which is worse than doing nothing.
