Electronic leak detection in Burnt Oak, Greater London
Independent electronic leak detection in Burnt Oak. We have completed more than 5,000 surveys across London and the South East.
- Holes around roof penetrations
- Leaks that return after repairs
- New membranes needing a check before handover
What happens on the day
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take as long as needed for the roof’s area and construction, which we’ll explain when we quote. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when you book.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Keep pets in another room
- Let us know about parking near the property
- Unlock side gates and any roof access doors
Book a survey
Booking is simple: just phone 07833 053749 or drop us an email, let us know about the property and we’ll recommend the right survey. The price is agreed up front.

Electronic leak detection in Burnt Oak
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. If you’re worried about breaches hidden under paving or planting and leaking laps in the waterproofing, we can find out what’s behind it, whatever the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Burnt Oak, the roof above may belong to the building rather than one flat.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Electronic leak detection around Burnt Oak
About 4.2 miles west lies Headstone Manor, a reminder of how long the area around Burnt Oak has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places like Broadwalk Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. Controlled parking zones are common in London, so mention any permit rules for Burnt Oak. If you own a rental within reach of Mill Hill Broadway station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Burnt Oak questions
Does a conservation area affect roof work in Burnt Oak?
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. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover Burnt Oak?
Yes, Burnt Oak is one of the places we work. Every survey there gets the same written report with photographs.
Which days do you carry out surveys?
Surveys run on weekdays and at weekends. To arrange a date, call 07833 053749 or use the contact form.
Does ELD work under paving or planting?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.
What happens next?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Will I get photos?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we’ll agree the details when booking.
When you need someone else
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- How wet the insulation is
- Some conductive membranes
- Areas we cannot reach or that can’t be tested
If you’re not sure which survey you need, call 07833 053749 or use the contact form and we will give you a straight answer. The full list of what we check.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Get leaks traced quickly
- Keep foot traffic on flat roofs to a minimum
- Find the breach before more patching
- Use boards when working on the roof
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
DIY checks: what’s safe
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That’s where a survey comes in.
What we look for on each type of roof
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes often appear.
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
