Do you need electronic leak detection in Forest Gate?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Most people get in touch after spotting one of these:
- Holes around roof penetrations
- Holes left by work on the roof
- Repairs that haven’t stopped the leak
- Leaks under green or ballasted roofs
For site and facilities teams at buildings like Woodgrange Infant School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Before you book any roof surveyor
- Which parts of the roof they’ll actually see
- How much experience they have with roofs like yours
- Whether any drone flown is registered with the CAA
- What the report includes, and whether it has photographs
Electronic leak detection in Forest Gate
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You will also know what to check next. We’re often asked to look into leaks through a covered membrane and new roofs to check before paving or planting, on flat roof membranes, roof terraces and balconies and green roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Forest Gate, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
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.

Landlord and commercial surveys in Forest Gate
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run on any day of the week, which helps when tenants work during the week.
With a portfolio of properties, surveys can be booked for more than one address. To discuss a number of properties, ring 07833 053749 or email us with the addresses.
What we do, step by step
Every roof is different, but as a rough guide the survey takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. If you have questions on the day, just ask. From the street, a London terrace typically shows only its front slope or parapet, so in Forest Gate we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- 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.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Check the loft hatch can be reached
- Let us know where we can park nearby
- Gather any invoices or paperwork from past roof work
How to book
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or drop us an email.
Advice
Electronic leak detection in Forest Gate: local notes
Historic houses such as Valentines Mansion, about 2.2 miles north-east, show how far back building in the area around Forest Gate goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church such as A Radical Church are often among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. For businesses in and around places like Stratford Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

- The extent of water in the insulation

- Sections we cannot safely access
If in doubt, phone 07833 053749 or email us and we will point you to the right survey before booking. What a survey covers and doesn’t.
What this survey covers
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
- Liquid-applied waterproofing
Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
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.
Why book with us

Useful tips for Forest Gate property owners
There is plenty you can do without going near the roof. Here’s what helps most:
- Tell us about the membrane and build-up if you know it
- Do not leave water getting in
- Check new waterproofing before handover
- Ask contractors to protect the membrane
Wet insulation may need attention after a leak. That’s something to discuss with your roofer and other checks can help judge it.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
FAQs for Forest Gate
Will parking be an issue for a roof survey in Forest Gate?
It can be, so it is useful to let us know about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
Do you cover Forest Gate?
We do. The survey and report are the same in Forest Gate as anywhere else.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll confirm suitability.
Can you survey at the weekend?
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 as you book.
How experienced are you?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
