What we repair

The six failures we see 90% of the time.

If your roof's doing something off this list, we've seen it and fixed it.

Active leaks

Water already coming in. Often urgent. We diagnose, weatherproof, and quote properly.

Failed laps & seams

Most felt and EPDM roofs fail at the joins first. A targeted patch can save the rest.

Damaged upstands

Where the roof meets a wall, parapet or chimney. Common failure point — fixable.

Storm or impact damage

Branch through the membrane, dislodged kerb, vandalism. We make it watertight again.

Cracks in GRP / fibreglass

GRP cracks aren't easily fixed in GRP. We patch in single ply for a lasting repair.

Ponding water issues

Water sitting on the roof? Usually a fall or drainage issue we can correct.

Repair or replace?

When does repair stop making sense?

The honest answer most roofers won't give you.

Repair is right when…
  • The rest of the roof has life left in it (under ~12 years old)
  • Damage is localised — one or two areas
  • The leak has an identifiable, isolated cause
  • Budget needs to spread over time
Replace instead when…
  • Roof is 15+ years old and felt/EPDM
  • Multiple leaks across different areas
  • Membrane is blistered, brittle or shrinking
  • You're paying for repairs every year

FAQ

Repair questions

The things people ring up and ask.

How much does a flat roof repair cost?
Most patch repairs are £250–£500. Larger repairs (multiple areas, scaffolding required) scale from there. We'll always tell you honestly whether repair is the right call or whether replacement makes more sense.
How quickly can you get out?
For active leaks in South Yorkshire we often visit same-day or next-day. Less urgent jobs scheduled within 5 working days.
Will the repair actually last?
On a roof with life left in it — yes. We use the same single-ply patches and welded seams we'd use on a new roof. A proper repair often outlasts the rest of the roof.
When is repair the wrong choice?
When the roof itself is at end of life. If the felt or GRP is brittle, blistered, or ponding everywhere, you're patching a sinking ship. We'll tell you straight if replacement is the right call.
Do you guarantee repairs?
Honest answer: repair guarantees are shorter than installation guarantees, and the length depends on the material we're working with. The reason is that when we patch one part of an older roof we can't guarantee a different part of the same roof won't fail next year — that's a problem with the wider roof, not with our repair. We give you the realistic guarantee terms in writing before we start.
Can you repair somebody else's install?
Yes. We repair single ply, felt, GRP, EPDM, asphalt — pretty much anything. Doesn't matter who fitted the original.
