- Leaks from plumbing, tanks or pipework rather than the roof
- The repair itself (the investigation finds and reports the cause)

Roof leak investigations for homes and businesses in Farringdon
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. We survey lead flashings, the roof space and slate and tile slopes, and the problems we are asked to look at most are leaks at a dormer or roof window and damp ceilings under a flat roof.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Farringdon, we inspect what we can reach safely and are given access to. Tell us when the water shows, and in what kind of weather.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It normally takes an hour or two for most homes, though a hard-to-trace leak can take longer. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Farringdon runs like any other.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Let us know about parking near the property
- Point out any leaks or damp patches
- Have any questions written down, so nothing gets missed
Arrange a survey
Getting a price is simple: just ring 07833 053749 or use the contact form and give us a few details about the property and we will explain which survey suits. The price is agreed up front.

Roof leak investigations in Farringdon: local notes
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Each of these roof types has its own typical places for water to get in. With Dr Johnson's House about 0.4 miles south-west, Farringdon sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
Homes near green spaces such as Barbican Conservatory can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. Take a building like Charterhouse Square School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Farringdon is about 2 miles north of London, in Greater London. Houses, flats, blocks and commercial buildings in Farringdon can all book roof leak investigations. We cover towns and villages across Greater London.

Farringdon questions
Do you cover Farringdon?
We do. The survey and report are the same in Farringdon as anywhere else.
Does a conservation area affect roof work in Farringdon?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can thermal imaging help find my roof leak?
We use thermal imaging where it helps, and it is part of the Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Will you definitely find the leak?
We can’t promise to find every leak on one visit. Many leave clear signs, but intermittent leaks that need particular weather can be harder. We report what we found and the likeliest sources.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a pitched roof it often runs down a rafter before it shows. Tracing that path is the heart of a leak investigation.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
How much is a survey?
Roof leak investigation starts from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT.
Do you need a roof leak investigation in Farringdon?
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can send that water under the coverings. Leaks from valleys often show up some distance away inside.
Common reasons to book include:
- Drips in the loft during heavy rain
- Drips from nail tips in a cold loft
- Water coming in around a roof light or dormer
- Ceiling stains that grow after rain
For landlords with property near Farringdon station, a tenant living with a leak needs the cause found, not just the stain painted over.
Before booking anyone
- Which viewpoints they use to see the roof
- Is there a chance to talk the report through?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- When you’ll get the report
Tips that help
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Photograph the stain each time it appears
- Check the loft is accessible
- Protect furniture and flooring under the leak
- Note the weather when the leak shows
If condensation is the cause, we explain it, and suggest how the loft space could be better ventilated. That avoids roof work that wouldn’t help.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
Why it is worth a survey now in Farringdon
Damp in a ceiling or loft can lead to mould. It is unpleasant, and it is harder to deal with once established. Stopping the water is the first step. In Farringdon, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
Our price is from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and the package you choose.

Different roofs, different checks
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, letting rain run behind the joint.
