Electronic leak detection for homes and businesses in Whitechapel
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you’ve noticed breaches hidden under paving or planting and waterproofing to test before it’s covered, we can find out what’s behind it.
On a London roof terrace or a flat roof over a back addition, water frequently 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 Whitechapel, the flat roof is often a shared part of the building.
Every survey ends with a written report, with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

When to book a survey in Whitechapel
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Problems we come across often include:
- Failed seams and laps
- Punctures from foot traffic or tools
- A flat roof leak that cannot be traced
- New membranes needing a check before handover
If you run a business near Surrey Quays Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- Whether the inside of the roof is included
- How long the report takes to arrive
- What exactly goes into their report
How it works
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. London terraces rarely offer a view of the whole roof from one spot, so a visit in Whitechapel moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- 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 method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Point out any leaks or damp patches
- Have any paperwork from past roof work to hand
- If the roof is shared, arrange access with whoever manages the building

FAQs for Whitechapel
Does a conservation area affect roof work in Whitechapel?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Will parking be an issue for a roof survey in Whitechapel?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we’ll work around them.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
Which days do you carry out surveys?
Surveys run seven days a week. To arrange a date, phone 07833 053749 or use the contact form.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can you survey in bad weather?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we will arrange another day with you.
What electronic leak detection looks like in Whitechapel
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Whitechapel has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
The streets around a church like St Mary Matfelon are often among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems typically start. If you run a hotel or guest house in or near Whitechapel, a roof problem can mean rooms out of use.

Why act early in Whitechapel
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.

What affects the price in Whitechapel
Prices always include VAT. The things that change the price are:
- If the survey needs thermal imaging or a drone
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
- Whether it’s a home or a commercial building
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
What helps most when you contact us:
- The address and postcode of the property
- Where water is showing inside, if it is
- What’s prompted the survey
- What kind of property and roof it is
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or send us an email.
What electronic leak detection does not cover
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- The extent of water in the insulation
- Water entering through details rather than the membrane
- Carrying out the repair work
