Electronic leak detection for homes and businesses in Plaistow
There are different ELD methods. Low-voltage testing is typically done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. If neither method suits your roof, we will tell you at the outset. We survey liquid-applied waterproofing, single-ply roofs and flat roof membranes, and common reasons people get in touch are leaks through a covered membrane and breaches around outlets and penetrations.
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 Plaistow, the flat roof is frequently a shared part of the building.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Electronic leak detection in Plaistow: local notes
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Plaistow 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.
Take an older house close to St Mary’s Church: the flat roofs on later extensions tend to wear out long before the main roof. For site and facilities teams at buildings such as Burnt Ash Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Plaistow is about 1 mile north of Bromley, in Greater London. Surveys in Plaistow work the same way as everywhere we cover: a careful inspection, photographs and a written report. Plaistow is one of the towns and villages in Greater London we cover for electronic leak detection. You can also see our page for London.
Electronic leak detection in BR1, BR2 and BR3 are booked the same way as anywhere else. We cover properties on Saxon Road, Arcus Road and Croft Road and the roads around them. Nearby, we also carry out electronic leak detection in Downham (1 mile north), Sundridge (1 mile east), Grove Park (1 mile north-east), Bromley (1 mile south) and Chinbrook (1 mile north-east).

Roof by roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Do you need electronic leak detection in Plaistow?
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
A survey can pick up problems such as:
- Stains far from any visible defect
- Water coming in under a flat roof
- Patched roofs that still leak
- Leaks at pipes, outlets or fixings
If you run a business near The Glades, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Before booking any roof surveyor
- Which parts of the roof they’ll actually see
- When you’ll get the report
- How long they’ve been surveying roofs
- Whether the price includes VAT
Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- Test new membranes before covering them
- Get leaks traced quickly
- Stay off the flat roof unless needed
- Keep outlets clear of debris
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
How the survey works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take more time on a big 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 the back of the roof is frequently 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 as 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.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- Find any records of previous roof work
- For a flat or shared roof, check access with the freeholder or managing agent
- Make sure pets are kept safely away
Arrange a survey

What a survey costs
Prices always include VAT. What changes the price is:
- How tall the building is and how easy the roof is to see
- The size of the roof
- The number of roofs, including extensions and garages
- The type of building, from a house to a block or an office
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you get in touch
There’s no need for technical words. Just let us know:
- The type of building and roof, like pitched or flat
- The reason for the survey, such as buying, a leak or storm damage
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.
Common questions in Plaistow
Is my home in Plaistow listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can parking be tricky for a visit in Plaistow?
Parking in Plaistow, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you look in the loft space?
Typically, if there is one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method so we check the roof first.
How much time does ELD need?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
Do you work in Plaistow?
Yes. We survey roofs across London and South East England, and that includes Plaistow.
DIY checks: what’s safe
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
