Electronic Leak Detection in Bethnal Green
Know where you stand with the flat roof membrane before you spend money on it. Electronic leak detection in Bethnal Green.
- Leaks through a flat roof with no obvious cause
- Leaks under green or ballasted roofs
- Leaking laps in the waterproofing
What we do, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes as long as needed for the size of the roof and how it’s built, 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 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 booking.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Check we can get to the back of the property
- Leave a clear route to the loft
- Have any questions written down, so nothing gets missed

Electronic leak detection in Bethnal Green: what you get
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. If testing isn’t possible, we’ll say so. If you are worried about patched roofs that still leak and leaks through a covered membrane, a survey will tell you what’s going on.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Bethnal Green, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Should I look at the roof myself first?
It’s useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

Common roof problems in Bethnal Green
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Common reasons to book include:
- Failed seams and laps
- Damp inside with no sign on the roof
- New roofs to check before paving or planting
- Repairs that haven’t stopped the leak
For site and facilities teams at buildings like Lawdale Junior School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Before booking anyone
- What the report includes, and whether it has photos
- Which viewpoints they use to see the roof
- Whether you can ask questions once you have the report
- What the survey will not cover
Rented homes, blocks and businesses
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Letting agents frequently book on a landlord’s behalf. Access is agreed with the tenant ahead of time.
When you need someone else
We only report everything that’s safely in view on the day, so some things are outside what a survey can do:
- Water entering through details rather than the membrane
- Areas we can’t reach or that cannot be tested
- Some conductive membranes

Bethnal Green: your questions answered
Will parking be an issue for a roof survey in Bethnal Green?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Do you look at commercial flat roofs near Bethnal Green, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Is it a structural engineer’s report?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Do you use drones?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you as you book.
Why act early in Bethnal Green
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. London’s older roofs frequently have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Why book with us
- Insured for professional indemnity and public liability
- An independent view of the roof
- Satisfaction rate of 98%
- Over 20 years’ experience

Electronic leak detection in Bethnal Green: local notes
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Sutton House, about 1.4 miles north, is one of the historic houses in the wider area around Bethnal Green. 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.
If yours is one of the older homes in the streets near St Peter's, the joins between later flat roofs and the old walls are where problems normally start. For businesses in and around places such as Hackney Walk, a flat roof over a business is out of sight and out of mind until it leaks.
