Typical things we’re asked to look at include:
- Leaks through a covered membrane
- Water coming in under a flat roof
- Waterproofing to test before it’s covered
- Leaks showing away from the breach

Electronic leak detection in Brasted Chart
We carry out electronic leak detection on flat roofs in Brasted Chart and across London and South East England. Testing normally takes a length of time set by the membrane area and the build-up, which we set out in the quote. Every roof is quoted on its size and build-up. You get a report with photos. We’re frequently asked to look into leaks at pipes, outlets or fixings and leaks that return after repairs, across flat roof membranes, single-ply roofs and commercial flat roofs.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Brasted Chart, 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.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What electronic leak detection looks like in Brasted Chart
About 1.2 miles west lies Quebec House, a reminder of how long the area around Brasted Chart has been built on. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Sevenoaks station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you live in an older home near Church of St Martin, the flat roofs on later extensions tend to wear out long before the main roof.

Useful tips for Brasted Chart property owners
Over many surveys, some simple habits stand out as worth the effort:
- Test new membranes before covering them
- Have roof specifications to hand
- Ask contractors to protect the membrane
- Note where leaks show inside and when
File the report with your roof paperwork. 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 we look for on each type of roof
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
What affects the price in Brasted Chart
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- The type of building, from a house to a block or an office
- Roof area
- Height and safe access
- The number of roofs, including extensions and garages

Helping us price your survey
The more you tell us, the easier it is to price the survey. When you contact us, it’s useful to mention:
- How the loft is reached, if there is one
- What made you get in touch
- Dates you’re working to, like exchange
- Photos of the roof, taken safely from ground level or a window
To book a survey, phone 07833 053749 or send us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
DIY checks: what’s safe
It’s 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.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
The survey, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes a time that depends on 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. Mention any building rules, key holders or managing agents as you book.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- If it isn’t your property yet, arrange access through the agent
- Let us know about parking near the property
- Make a note of anything you’d like us to look at
Booking a survey
Booking is simple: just call 07833 053749 or email us and give us some details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
Advice
Common questions in Brasted Chart
Can parking be tricky for a visit in Brasted Chart?
Sometimes, yes. If Brasted Chart has controlled parking where you are, a visitor permit is the easiest answer.
Is my home in Brasted Chart listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing usually needs a wet surface and high-voltage methods need the membrane dry and exposed.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.
