About our electronic leak detection in Tottenham
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. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. We survey roof terraces and balconies, commercial flat roofs and single-ply roofs, and people most often book us about leaks that return after repairs and leaks through a covered membrane.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Tottenham, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we cannot see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

How the survey works
Every roof is different; as a rough guide, the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we’re there. For a visit in Tottenham, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Mention any parking restrictions on your street
- Gather any invoices or paperwork from past roof work
- If you are buying, let the agent know when we’re coming
Book a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or send us an email when you are ready.
Advice
Why act early in Tottenham
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Any roof job in Tottenham means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Tottenham questions
Do you cover Tottenham?
Yes. We work right across London and the South East, and Tottenham is part of that. Just ring 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Will parking be an issue for a roof survey in Tottenham?
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 when booking.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
What will the report tell me?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Does the report include photographs?
Yes. The report includes photos of what we found, so you can see each point for yourself.
What do I do with the report?
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.
How long will testing take?
Testing usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.

Local flat roofs in Tottenham
The wider area around Tottenham has a long history of building, with Bruce Castle about 0.3 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Landlords with a home close to Bruce Grove station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings such as The Mulberry Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Common roof problems in Tottenham
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in long before anyone notices.
Common reasons to book include:
- Leaks through a flat roof with no obvious cause
- Punctures from foot traffic or tools
- Leaking laps in the waterproofing
- Stains far from any visible defect
If you run a business near The Mall Wood Green, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Questions to ask before booking
- Whether they hold professional indemnity and public liability insurance

- Will the report include photos?
- Whether you can ask questions once you have the report
