Electronic Leak Detection in Canary Wharf
A careful look at the flat roof membrane at your property in Canary Wharf, and put it all in a report with photos.
- Stains far from any visible defect
- Holes left by work on the roof
- Repairs that haven’t stopped the leak
Canary Wharf: your questions answered
Is my home in Canary Wharf listed or in a conservation area?
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.
Is parking a problem for a survey in Canary Wharf?
Parking in Canary Wharf, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when booking.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Are you structural engineers?
No. We note visible signs like sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
How is ELD priced?
We quote for each roof individually. Tell us about the roof and where it leaks, and phone 07833 053749 or send us an email for a quote.
Electronic leak detection for homes and businesses in Canary Wharf
There are different ELD methods. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. We’ll say if your roof doesn’t suit either method before any testing starts. We are often asked to look into leaking laps in the waterproofing and leaks through a flat roof with no obvious cause, across liquid-applied waterproofing, commercial flat roofs and roof terraces and balconies.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Canary Wharf, 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.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Electronic leak detection in Canary Wharf: local notes
Canary Wharf has a number of hotels within about a mile and a half. If you look after one, a leak through a flat roof can put a room out of use. Historic houses such as Queen's House, about 1.8 miles south, show how far back building in the area around Canary Wharf goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
A roof leak in a hotel or guest house around Canary Wharf means lost rooms as well as repairs. If you look after a building such as Our Lady and St Joseph Catholic Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you live in an older home near St Peter's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Canary Wharf is about 2 miles north-west of Greenwich, in Greater London. Wherever you are in Canary Wharf, we can carry out electronic leak detection at your property. Canary Wharf is one of the towns and villages in Greater London where we work.
Every address in E14, SE16 and E22 is covered for electronic leak detection. If you need electronic leak detection at a property on Castor Lane, Cassilis Road and Dockyard Lane or a nearby road, we can help. Canary Wharf sits on or near the A1261. Other places close to Canary Wharf include London Docklands (1 mile east), Poplar (1 mile north-east), Heron Quays (1 mile south-west), Coldharbour (1 mile east) and Blackwall (1 mile east). Within a short drive, we also cover London (3 miles west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (4 miles west) and Shoreditch (3 miles north-west).

Honest limits
It helps to know what a survey will not do before booking:
- Leaks from walls, copings or rooflights
- How wet the insulation is
- Repairing the breaches (that’s for your roofer)
If in doubt, ring 07833 053749 or drop us an email and we will recommend the right survey before booking. The full list of what we check.
What this survey covers
- Liquid-applied waterproofing
- Green roofs
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
- Commercial flat roofs
How the survey works
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Many London properties are flats or terraces with no 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, tell us as you book.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Point out any leaks or damp patches
- If the roof is shared, arrange access with whoever manages the building
- Move anything stored under the loft hatch
How to book
Most bookings start with a short call: call 07833 053749 or use the contact form and we will ask a few questions about the roof. The price is agreed before a date is set.

What a survey costs
Prices vary from roof to roof, for these reasons:
- Roof area
- House, block, shop or office
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What we need to know
There’s no need for technical words. Just tell us:
- When you need the report by
- Access details, such as a loft hatch or a shared roof
- The property’s address and postcode
- What’s prompted the survey
We confirm the price for your survey before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, phone 07833 053749 or drop us an email.
What happens if roof problems are left?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. In Canary Wharf, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
To find out what your survey will cost, ring 07833 053749 or drop us an email with the address and a few details. We will confirm the figure before booking.

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Make sure trades protect the waterproofing
- Do not let outlets block
- Stay off the flat roof unless needed
- Avoid repeated repairs without finding the cause
Wet insulation may need attention after a leak. That’s something to discuss with your roofer, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Surveys for landlords and agents in Canary Wharf
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which can make access easier.
