Electronic leak detection in West Barnes: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. If you’ve noticed leaks that return after repairs and holes around roof penetrations, a survey will tell you what’s going on.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In West Barnes, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

Useful tips for West Barnes property owners
There’s plenty you can do without going near the roof. Here’s what helps most:
- Do not leave water getting in
- Have roof specifications to hand
- Do not keep patching the same spot
- Clear flat roof outlets regularly
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.

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. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.

The survey, step by step

Questions from West Barnes
Will parking be an issue for a roof survey in West Barnes?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Do you cover West Barnes?
Yes, West Barnes is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and a few details, and we’ll talk through which survey suits.
How is ELD priced?
We quote for each roof individually. Send us details of the roof. Just call 07833 053749 or email us for a quote.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Rented homes, blocks and businesses
Landlords and letting agents in West Barnes book surveys as well as homeowners. A photo-illustrated written report gives you a clear record of the flat roof membrane, useful for planning maintenance.
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
DIY checks: what’s safe
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
