Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Electronic leak detection for homes and businesses in Putney
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 is a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you are worried about leaks showing away from the breach and holes around roof penetrations, 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 Putney, the roof above may belong to the building rather than one flat.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

What a survey costs
The price reflects the time and kit the roof needs. That comes down to:
- Building height and the viewpoints available
- Features like valleys, chimneys, dormers and parapets
- How big the roof is
- The type of building, from a house to a block or an office
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
We’ll typically ask about:
- Any stains, drips or damp patches you’ve seen indoors
- Your postcode, so we can check access and travel
- Your timetable, like an exchange date
- The type of building and roof, such as pitched or flat

Electronic leak detection around Putney
Historic houses such as Fulham Palace, about 0.6 miles north-east, show how far back building in the area around Putney goes. On older houses around here, roofs often 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. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If your house is among the older ones in the streets near Polish Church of St John the Evangelist, the joins between later flat roofs and the old walls are where problems usually start. As a London address, Putney can be tricky for parking: let us know about parking bays, permits or a driveway when you book. If you run a business near Putney Exchange, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Your questions about electronic leak detection in Putney
Does a conservation area affect roof work in Putney?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is parking a problem for a survey in Putney?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available as you book.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
How do I arrange electronic leak detection in Putney?
To book, phone 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Tell us what you know about the roof and we’ll confirm suitability.
Is this an asbestos survey?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Can you find leaks on a covered flat roof?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We talk this through first.
Rented homes, blocks and businesses
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
Landlords, agents and building managers in Putney and across Greater London can book any of our surveys. To discuss a property or a block, call 07833 053749 or use the contact form.
How it works
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before the survey
- Move anything stored under the loft hatch
- Tell us about parking before the day
- Tell us about any leaks, stains or damp patches you know of
Book a survey
We confirm the price for your roof before booking, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, call 07833 053749 or email us.

Practical tips
These tips come from what we see on roofs every week, before and after a survey:
- Keep outlets clear of debris
- Keep a note of leaks after rain
- Share any drawings of the roof
- Check new waterproofing before handover
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
What this survey can’t tell you
To be straight with you, a roof survey has limits:
- Parts of the roof covered by fixed equipment
- Fixing the holes we find
- The extent of water in the insulation
