Electronic leak detection for homes and businesses in South Acton
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you are worried about damp inside with no sign on the roof and new membranes needing a check before handover, a survey will tell you what’s going on.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in South Acton, the roof above may belong to the building rather than one flat.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photograph. You will see the good as well as the bad.

What happens on the day
We check the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. London terraces rarely offer a view of the whole roof from one spot, so a visit in South Acton moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work
- Check pets are kept safely away

Related advice
Leave it or get it looked at?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. In South Acton, 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.

Questions from South Acton
Can parking be tricky for a visit in South Acton?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
How do I find out if my home in South Acton is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. We’ll talk about access when you book.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We’re a CAA-registered drone operator.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That is how we locate breaches you can’t see.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Electronic leak detection around South Acton
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. The wider area around South Acton has a long history of building, with Gunnersbury Park about 0.3 miles south-west. On older houses around here, roofs frequently 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.
If you run a business near Livat Hammersmith, the flat roofs over shops and commercial units are worth checking before a leak, not after. For landlords with property near South Acton station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
