Electronic leak detection in Welling: what you get
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. We survey green roofs, liquid-applied waterproofing and commercial flat roofs, and the problems we’re asked to look at most are leaks at pipes, outlets or fixings and leaking laps in the waterproofing.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Welling, the roof above may belong to the building rather than one flat.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Common roof problems in Welling
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
We are often asked to look at:
- Punctures from foot traffic or tools
- New membranes needing a check before handover
- Leaks showing away from the breach
- Failed seams and laps
Welling is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
Before booking any roof surveyor

Common questions in Welling
Is my home in Welling listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out roof surveys in Welling?
Yes. We work right across London and South East England, and Welling is part of that. You can phone 07833 053749 or drop us an email with the address and some details, and we will talk through which survey suits.
Will I get photos?
Yes. Photographs are part of every report.
What if it rains on the day?
It depends on the weather and the survey. In strong wind or heavy rain, a drone can’t fly and access may not be safe, so we’d move the date with you.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days as you book.
DIY checks: what’s safe
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. A typical survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Welling runs like any other.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
- If you are buying, let the agent know when we’re coming

Local flat roofs in Welling
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Danson House, about 0.4 miles south-east, is one of the historic houses in the wider area around Welling. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
For businesses in and around places such as Broadway Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you live in an older home near St John's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Welling is about 9 miles east of London, in Greater London. Bookings from Welling are handled just like any other: a call or an email, a price, then a date. We cover towns and villages across Greater London, large and small. Our London page covers surveys nearby.

Leave it or get it looked at?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In Welling, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before you book.
