Tottenham Green Electronic Leak Detection
Electronic leak detection in Tottenham Green from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us.
- Leaks through a flat roof with no obvious cause
- Failed seams and laps
- Breaches hidden under paving or planting
The survey, step by step
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. In Tottenham Green, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Preparing for the visit
- Let us know about parking near the property
- Check pets are kept safely away
- Agree roof access with the managing agent if it is shared

Electronic leak detection in Tottenham Green: what you get
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We will say if ELD will not work on your roof at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It saves a wasted visit. If you’re worried about holes left by work on the roof and leaks showing away from the breach, a survey will tell you what’s going on, 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 block or conversion in Tottenham Green, the flat roof is often a shared part of the building.
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.

Do you need electronic leak detection in Tottenham Green?
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
We are often asked to look at:
- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
- Waterproofing to test before it’s covered
- Breaches around outlets and penetrations
For an older house near a landmark such as Church of Holy Trinity, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before you book any roof surveyor
- What exactly goes into their report
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- What they won’t be able to tell you
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extra roofs, like extensions, dormers or garages
- Roof area
- The shape of the roof and its details
- Height and safe access
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
Booking your survey
If you can, have these to hand when you contact us:
- Anything about access we should know
- Dates you are working to, like exchange
- Where any leaks, stains or damp patches show inside
- Photos of the roof, taken safely from the ground or a window
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.
Honest limits
Before booking, it is worth knowing what a survey won’t do:
- Areas we can’t reach or that cannot be tested
- Repairing the breaches (that’s for your roofer)
- Roofs whose membrane or build-up is not suitable
If in doubt, phone 07833 053749 or email us and we will suggest the right survey before you book. What a survey covers and does not.

Questions from Tottenham Green
Is parking a problem for a survey in Tottenham Green?
It can be, so it’s useful to let us know about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Is Tottenham Green in the area you cover?
Yes. We work right across London and South East England, and Tottenham Green is part of that. You can call 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
What does the report include?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Mention it when you contact us and we will plan the survey around it.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.

Local flat roofs in Tottenham Green
With Bruce Castle about 0.9 miles north, Tottenham Green sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you run a business near The Mall Wood Green, a flat roof over a business is out of sight and out of mind until it leaks. For landlords with property near Seven Sisters station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
