Electronic leak detection in Heron Quays
We carry out electronic leak detection on flat roofs in Heron Quays and across London and the South East. Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. You get a written report with photos. Common reasons to book are leaks through a covered membrane and leaks that return after repairs, on green roofs, commercial flat roofs and liquid-applied waterproofing.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Heron Quays, the roof above may belong to the building rather than one flat.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

What affects the cost of electronic leak detection
Prices always include VAT. What changes the price is:
- Extensions, dormers and garages with roofs of their own
- How tall the building is and how easy the roof is to see
- How big the roof is
- Whether thermal imaging or a drone is needed
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. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to let us know when you contact us
Some details help us recommend the right survey and price. When you get in touch, it helps to mention:
- The property’s address and postcode
- What made you get in touch
- Dates you are working to, such as exchange
- Pictures of the roof from a safe spot, if you have them
Most bookings start with a short call: phone 07833 053749 or email us, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
For landlords and managing agents
Any of our surveys can be booked by landlords, agents and building managers in Heron Quays. For a price for a let property or a block, call 07833 053749 or email us.

Leave it or get it looked at?
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. A blocked outlet ignored for a winter or two can mean damp walls inside.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
What you get with us
- CAA-registered drone operator (Flyer ID and Operator ID)
- A photo-illustrated written report
- 20+ years’ experience
- Thermal imaging and drone inspection where they help

What we do, step by step
We don’t take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. The survey usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. In Heron Quays, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when booking.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before the survey
- Clear the way to the loft hatch
- Have any paperwork from past roof work to hand
- For flats, check roof access has been agreed
Booking a survey
Our phone lines are open seven days a week. For a price or to book, call 07833 053749 or email us.

Electronic leak detection around Heron Quays
Heron Quays 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. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Heron Quays is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building like Seven Mills Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Historic houses like Queen's House, about 1.7 miles south-east, show how far back building around Heron Quays goes. Older homes nearby may have later flat-roofed extensions or dormers, frequently re-covered more than once. If you own a rental within reach of Canary Wharf station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

FAQs for Heron Quays
Can parking be tricky for a visit in Heron Quays?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
Does a conservation area affect roof work in Heron Quays?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
How do I book a survey in Heron Quays?
To arrange a survey, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Will you check the loft?
Typically, if there’s one and it can be reached safely. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or use the contact form.
Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Act on new leaks promptly
- Let us know about the membrane and build-up if you know it
- Stay off the flat roof unless needed
- Consider ELD before paving or planting goes on
Questions about the results are welcome. We can talk you through the findings.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
