Roof Leak Repair Services in London

Most leaks come from a small number of weak points. We repair all of them:

Missing, cracked or slipped tiles and slates, including nail sickness on older slate roofs.
Lead flashing around chimneys, walls, skylights and soil pipes.
Chimney stacks, including re-pointing, flaunching and re-leading.
Flat roof leaks, from felt and EPDM to GRP (fibreglass) roofs.
Ridge and hip tiles, including re-bedding loose mortar.
Valleys, gutters and fascias where water backs up or overflows.
Skylights and Velux windows with failed seals or flashing.

If your flat roof is beyond repair, see our flat roof installation service. If gutters or boards are causing the problem, our guttering and soffits and fascias teams can help.

Types of Roof We Repair

We handle leaks on:

Victorian and Edwardian terraces with slate or clay tile roofs
1930s semis with concrete or clay tiles
Flat-roof extensions, garages and dormers
Bay windows and porches with lead or felt details
Fibreglass (GRP) and EPDM flat roofs

Each roof type fails differently. Slate roofs tend to lose slates as old nails corrode. Flat roofs split at seams and corners. Flashing wears out wherever two materials meet. Knowing the usual weak points on each roof is why we can find leaks faster.

How We Find and Repair a Roof Leak

Water rarely drops straight down from the hole. It runs along rafters, felt and pipes first. So a stain on the ceiling is only a clue.

We work from the outside in. We check the roof surface, flashings, valleys and gutters. Then we check the loft for water tracks, staining and wet insulation. Only then do we decide on a repair.

Our process:

Inspection: We look at the roof outside and the loft inside, and ask you where and when the leak appears.
Diagnosis with photos: We show you what we found and where the water is getting in.
Written quote: You get the repair options and the price before work starts.
Repair: We fix the cause, not just the visible symptom, using materials that match your roof.
Final check: We inspect the finished repair and leave the site tidy. Our workmanship is guaranteed, and the exact terms are written on your quote.

Once the leak is traced, we carry out the permanent fix as part of our roof repair London service. Common causes have their own guides: tiled and slate roof repair, chimney repairs and roof cleaning, which also clears moss that blocks gutters.

What Happens During a Leak Inspection

Here is what to expect when we visit:

We ask when the leak started and whether it follows rain, wind or neither.
We inspect the roof surface, flashings, chimney, valleys and gutters.
We check the loft for damp timber, mould and wet insulation, where we can access it safely.
We photograph each fault so you can see it yourself.
We explain the cause, the repair options and the cost. You receive a written quote.

If water is coming in right now, tell us when you call. We can arrange temporary protection while the permanent repair is booked.

Why Fix a Roof Leak Quickly

Small leaks soak into insulation, timber and plaster before you can see them. Insulation loses its thermal value when wet. Timber can rot. Mould spreads in damp conditions, which is a particular concern for children and people with asthma.

Roof work is dangerous, too. The Health and Safety Executive publishes guidance on safe working on roofs. It’s one reason we advise against DIY repairs at height.

Not sure whether you have a leak? Read our guide to the signs of a leaking roof. To understand what’s behind it, see why your roof is leaking. Regular checks help prevent problems, so ask about our roof maintenance service.

Roof Leak Repair FAQs

How much does roof leak repair in London cost?

It depends on the cause. A small tile or flashing repair costs far less than a flat roof replacement. We inspect first and give you a written quote before any work begins.

Do you offer free quotes?

Yes. We offer free, no-obligation quotes. Call us or use our contact page.

How quickly can you attend a leaking roof?

We aim to visit within a day. Call us to check availability, and tell us if the leak is active.

Can a leak be repaired in winter or in the rain?

Many repairs can go ahead year-round, but some flat roof materials need dry conditions to cure properly. We’ll tell you honestly whether a permanent fix is possible, or whether a temporary one is safer first.

Does home insurance cover a leaking roof?

It depends on the cause. Storm damage is often covered, while wear and tear usually isn’t. Photograph the damage before repairs begin and check your policy.

Do you repair flat roof leaks?

Yes. We repair felt, EPDM and GRP flat roofs, and we can advise if a full replacement is the better option.

Which areas do you cover?

All of London, including Camden, Islington, Brent, Barnet, Harrow, Ealing, Hackney and Croydon.
