About our electronic leak detection in Thamesmead
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you’re worried about patched roofs that still leak and leaks through a covered membrane, we can find out what’s behind it, on liquid-applied waterproofing, commercial flat roofs and green roofs alike.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Thamesmead, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to.

What we’re asked to look at in Thamesmead
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Signs worth acting on include:
- Damp inside with no sign on the roof
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
- Water coming in under a flat roof
If you let a flat or house near Abbey Wood station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- Which parts of the roof they’ll actually see
- Do they have a CAA Flyer ID and Operator ID for drone work?
- When you will get the report
- What they won’t be able to tell you
For landlords and managing agents
Letting agents can arrange access with tenants. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
What affects the price in Thamesmead
Several things affect the price of a survey:
- The shape of the roof and its details
- Whether thermal imaging or a drone is needed
- Whether it is a home or a commercial building
- Extensions, dormers and garages with roofs of their own
For a price for your roof in Thamesmead, phone 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

Electronic leak detection in Thamesmead: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Eastbury Manor House about 2.4 miles north-west, Thamesmead sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For an older house near a landmark such as St Paul, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a shop, office or commercial unit, for example near Gallions Reach Shopping Park, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Thamesmead is about 2 miles north-east of Plumstead, in Greater London. Houses, flats, blocks and commercial buildings in Thamesmead can all book electronic leak detection. Our area takes in places right across Greater London, from the larger towns to small villages. We also survey roofs in London.

The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes a length of time set by 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 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.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- Tell us where we can park nearby
- Gather any invoices or paperwork from past roof work

Advice
Thamesmead questions
Does a conservation area affect roof work in Thamesmead?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Thamesmead in the area you cover?
Yes, Thamesmead is one of the places we work. The survey and report are the same in Thamesmead as anywhere else, and visits run on weekdays and weekends.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Let us know what you know about the roof and we’ll check whether ELD will work.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
Honest limits
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Water entering through details rather than the membrane
- Sections we cannot safely access
- Some conductive membranes
If you’re not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer. The full list of what we check.
What we check
- Commercial flat roofs
- Single-ply roofs
- Flat roof membranes
- Green roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
Before and after the survey
These tips come from what we see on roofs every week:
- Test new membranes before covering them
- Get leaks traced quickly
- Don’t let outlets block
- Tell us about the membrane and build-up if you know it
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
