How electronic leak detection works in Elmers End
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a photo-illustrated written report of each breach found. We survey commercial flat roofs, single-ply roofs and green roofs, and common reasons people get in touch are leaks that return after repairs and waterproofing to test before it’s covered.
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 Elmers End, the roof above may belong to the building rather than one flat.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, with the urgent items made clear.

What electronic leak detection looks like in Elmers End
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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Kingswood House, about 2.6 miles north-west, is one of the historic houses in the wider area around Elmers End. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Elmers End station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark such as St James's Church, the joins between later flat roofs and the old walls are where problems normally start. If you run a business near Whitgift Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Useful tips for Elmers End property owners
From years of surveys, a few habits stand out as worth the effort:
- Keep foot traffic on flat roofs to a minimum
- Avoid repeated repairs without finding the cause
- Don’t let outlets block
- Check new waterproofing before handover
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Act on leaks quickly. Water under a membrane can spread.
Different roofs, different checks
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Inverted and paved roofs
Paving and terraces cover the membrane. Whether it can be tested depends on the build-up.
Elmers End questions
Is parking a problem for a survey in Elmers End?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
How do I find out if my home in Elmers End is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
Can you inspect my roof with a drone?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Share any details you have and we’ll confirm suitability.
How experienced are you?
More than 5,000 surveys over 20+ years.

What we do, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Elmers End moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Check we can get to the back of the property
- For flats, check roof access has been agreed
- Gather any invoices or paperwork from past roof work
