How we repair a leaking roof
- Tell us what you see. When the leak shows, which room it shows in and whether wind or heavy rain makes it worse. Photos from inside and from the ground help.
- Find the cause. We check the slope above the stain, then the ridge, valleys, flashings and chimneys around it. Water runs along felt and timbers, so the cause is often a metre or more from the stain.
- Written quote. You get the repair described in plain words, with its price, before any work starts.
- The repair. Slipped or broken tiles are replaced, ridges re-fixed, flashings renewed or valleys rebuilt, depending on what failed.
- Check and record. The repair is checked, the area is cleared and you get photos of the finished work. Repairs carry a 12 month guarantee as standard, in writing.
Signs you need a roof repair
- A brown stain spreading on a ceiling
- Tiles or slates on the lawn after wind
- A ridge tile that has shifted or lost its mortar
- Damp on a chimney breast inside
- Moss and debris collecting in a valley
- Dripping inside the loft during heavy rain
Common repairs we carry out
- Slipped and broken tiles or slates: Replaced and fixed back in, matched to your roof as closely as possible.
- Ridge and hip repairs: Loose ridge tiles re-bedded or converted to a dry fix system, as in our gallery photo of clay ridge tiles being re-bedded.
- Valley repairs: Worn valleys stripped back and rebuilt on new membrane and battens, as in our roof valley rebuild.
- Flashings and chimneys: Lead flashings renewed and chimney flaunching replaced where the mortar has cracked.
How long it takes
Most repairs are finished in a single visit. Valley rebuilds and chimney work take a day or two, and jobs that need scaffold take longer to set up. In an emergency we make the roof safe first and book the permanent repair after.
What affects the price
- How high the roof is and how we reach it
- Whether scaffold or a tower is needed
- What has failed: a tile, a ridge, a valley or a flashing
- How far the water damage has spread under the covering
- Matching older tiles or slates
See the roof repair cost guide for our pitched and flat roof repair ranges.
Aftercare
Check the ceiling where the leak showed after the next heavy rain and tell us if it returns. Clear gutters and valleys once a year so water does not back up under the tiles. Keep the photos and the written guarantee with your house papers.
