Recognise the symptom?

Spotted one of these? We’ll trace it and stop it

A flat roof leak rarely shows where the water actually gets in, it tracks along the felt and timbers before it drips inside. Find your symptom below, then call us and a real roofer will trace it to the source and put it right.

Water coming through roof felt

The felt has split, blistered or perished and rain is getting straight through it.

We trace the failure, then patch, re-bond or re-felt the area and water-test it.

Flat roof leaking through ceiling

A damp patch or active drip is showing on the ceiling in the room below.

We find where the water gets in, not just where it drips, and seal it properly.

A leaking felt roof

An older felt roof is letting water in at the laps, upstands or around detail.

A leaking felt roof repair on the first visit, with honest advice if it needs more.

Flat roof leaking where it joins the house

Water comes in where the flat roof meets a wall or the main house.

We renew the failed flashing or upstand at the join and make it watertight.

Flat roof leaking around vent pipe

Water is tracking in around a soil vent, flue or pipe through the roof.

We re-seal or renew the collar around the vent pipe and stop the leak at source.

Leaking flat roof from inside

You can see daylight, damp timber or dripping water from inside the loft.

We trace it from both sides, find the entry point and carry out a lasting repair.

Water tracks further into the felt and timber every time it rains. Tell us the symptom and we’ll trace it and stop it at the source.

The right approach

We trace the leak to its source, then fix it

A leaking flat roof from inside rarely shows where the water gets in, it tracks along the felt and timbers before it drips. We find the actual entry point first, then carry out a lasting repair, instead of chasing the damp from one patch to the next.

We check the whole roof, the felt, the upstands, the flashing where it joins the house and the seals around any vent pipes, because the leak is often nowhere near the wet patch on your ceiling. Most leaks are traced and repaired on the first visit. Where the covering has reached the end of its life, we’ll tell you honestly and quote before any bigger work starts.

As Icopal-approved contractors, every repair is carried out to the same standard as a full installation. Photo records are taken before, during and after, ideal if you need to make an insurance claim.

  • Real source traced, not just the visible wet patch
  • Felt, flashing, joins and vent pipes all checked
  • Photo records for your insurance claim
  • Water-tested and guaranteed in writing

Questions

Emergency flat roof repair - your questions answered

Felt perishes, blisters and splits with age, and the laps and upstands are where it usually goes first. Once water is coming through the roof felt it tracks along the boards before it drips, so the entry point is rarely above the wet patch. We trace it and carry out a proper leaking felt roof repair.
Catch the drip with a bucket, move anything valuable clear, and if it's safe switch off electrics in that room. Don't go up on the roof yourself. Call us and a real roofer will find where the water gets in and stop it.
That join relies on flashing or an upstand sealing the gap where the flat roof meets the wall. When that fails, water runs straight in. We renew the flashing or upstand at the join and water-test it on completion.
Yes. A flat roof leaking around a vent pipe is almost always a perished collar or seal where the pipe passes through the covering. We re-seal or renew the collar so it's watertight again.
It means water is already getting through the covering and into the structure, so it's worth acting on before it rots the timber or reaches the ceiling. Call us and we'll trace it from both sides and repair it.
No. Coming out, finding the source and quoting are all free. You only pay if you decide to go ahead with the repair.
