Electronic leak detection for homes and businesses in London Docklands
Our ELD testing covers flat roofs in London Docklands and the rest of London and the South East. Testing usually takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a report with photographs. Typical surveys look at gaps at membrane joints and breaches hidden under paving or planting, on single-ply roofs, liquid-applied waterproofing and flat roof membranes.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In London Docklands, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
After the visit, you get a report with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

What we are asked to look at in London Docklands
When the membrane is buried, holes cannot be seen at all. Electronic methods can help on some of these roofs, depending on the build-up.
Here are some of the things we see frequently:
- Holes around roof penetrations
- Leaking laps in the waterproofing
- Waterproofing to test before it is covered
- Punctures from foot traffic or tools
For businesses in and around places such as Surrey Quays Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Before you book any roof surveyor
- Is VAT included in the price?
- What exactly goes into their report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included

Roof by roof
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but punctures and seam failures still happen.
Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. We test where the roof suits it.
The survey, step by step
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. In London Docklands, as in much of London, lots 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. Mention any building rules, key holders or managing agents when you book.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive
- Note where any stains or damp appear
- Leave side gates unlocked
- For flats, make sure roof access has been agreed

Electronic leak detection in London Docklands: local notes
The wider area around London Docklands has a long history of building, with Queen's House about 1.8 miles south. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Many homes in inner London are Victorian and Edwardian terraces, often with 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. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
A roof leak in a hotel or guest house around London Docklands means lost rooms as well as repairs, so it pays to find faults before guests do. Take an older house close to St Peter's Church: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

London Docklands questions
How do I find out if my home in London Docklands is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Can you look at the flat roof of a hotel or office near London Docklands?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building.
Do you cover London Docklands for electronic leak detection?
Yes. Our area covers London and South East England, London Docklands included.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access when you book.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What’s the best way to book?
Simply ring 07833 053749 or use the contact form with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Can you survey in bad weather?
Light rain doesn’t normally stop a survey, 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.
Useful tips for London Docklands property owners
Here are a few things we’d tell any owner, before and after a survey:
- Stay off the flat roof unless needed
- Make sure trades protect the waterproofing
- Don’t keep patching the same spot
- Consider ELD before paving or planting goes on
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
What affects the cost of electronic leak detection
We confirm the exact price before you book. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- How big the roof is
- How many separate roofs there are, like extensions, dormers and garages
- Building height and the viewpoints available
The cost of a survey depends on the roof: 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.
Getting in touch
Getting the details right at the start saves time. Please include:
- Dates you are working to, such as exchange

- The kind of building and roof involved
- Where water is showing inside, if it is
Photos help, if you have them. Pictures from the ground or a window are fine. To get started, phone 07833 053749 or email us.
