Electronic leak detection in Addiscombe
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We’ll tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. We survey single-ply roofs, liquid-applied waterproofing and green roofs, and the problems we’re asked to look at most are leaks showing away from the breach and leaking laps in the waterproofing.
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 Addiscombe, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Roof by roof
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Leave it or get it looked at?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. Any roof job in Addiscombe means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.

FAQs for Addiscombe
Do you cover Addiscombe?
Yes, Addiscombe is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Will parking be an issue for a roof survey in Addiscombe?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Does ELD work under paving or planting?
It can be possible, depending on the roof. What sits on the membrane affects the method so we look at the roof first.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where applicable, and the report records anything we couldn’t see.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we will check whether ELD will work.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.
Common roof problems in Addiscombe
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs, depending on the build-up.
People usually book a survey after spotting one of these:
- Leaks showing away from the breach
- New roofs to check before paving or planting
- Failed seams and laps
- Repairs that haven’t stopped the leak
If you let a flat or house near Norwood Junction station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking anyone
- Whether any drone flown is registered with the CAA
- What happens after the report arrives
- How much experience they have with roofs like yours
- What’s outside the scope of the survey
Honest limits
It’s useful to know what a survey won’t do before booking:
- Water entering through details rather than the membrane
- Sections we can’t safely access
- Carrying out the repair work
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before you book. What our survey covers.

The survey, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. 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, let us know as you book.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Find any records of previous roof work
- If the roof is shared, arrange access with whoever manages the building
- Mention any parking restrictions on your street
Getting a price
We confirm the price for the job before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or use the contact form.

Practical tips
Small things make a difference. Some pointers:
- Stay off the flat roof unless needed
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
- Get leaks traced quickly
Questions about the results are welcome. We will explain what was found and what it means.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Electronic leak detection around Addiscombe
Addington Palace, about 2 miles south-east, is one of the historic houses in the wider area around Addiscombe. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
As a London address, Addiscombe can be tricky for parking: a visitor permit or a nearby bay makes the day easier. Shop and office owners around St George's Walk may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
