How electronic leak detection works in Hanger Hill
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We’ll tell you if the roof can’t be tested. If you’re worried about leaks through a covered membrane and new roofs to check before paving or planting, we can find out what’s behind it.
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. In Hanger Hill, 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.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later.

How it works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for 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. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Hanger Hill runs like any other.
- You tell us 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 photos shows where each breach is.
Getting ready for the survey
- Point out any leaks or damp patches
- Have keys ready for side gates, garages or roof access doors
- If it isn’t your property yet, arrange access through the agent

Advice
When to book a survey in Hanger Hill
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
A survey can pick up problems such as:
- Leaks through a flat roof with no obvious cause
- Damage from equipment installers
- New membranes needing a check before handover
- Breaches hidden under paving or planting
Landlords with a home close to Acton Main Line station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before booking
- Whether the loft space is looked at, where there is one
- Is there a chance to talk the report through?
- Are they insured for the work?
- Whether the price includes VAT
Flat and commercial roofs around Hanger Hill
Within a mile and a half or so of Hanger Hill there are several hotels, and hotels, like offices and blocks of flats, frequently have flat roofs. If you look after one, a leak through a flat roof can put a room out of use. The wider area around Hanger Hill has a long history of building, with Pitzhanger Manor about 1.2 miles south-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
For businesses in and around places such as London Designer Outlet, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take a building like Holy Family Catholic Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What a survey costs
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- How tall the building is and how easy the roof is to see
- Any need for thermal images or a drone flight
- Extra roofs, like extensions, dormers or garages
- Chimneys, valleys, parapets and other details
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. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Your questions about electronic leak detection in Hanger Hill
Can parking be tricky for a visit in Hanger Hill?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
How do I find out if my home in Hanger Hill is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when you book.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll confirm suitability.
What is electronic leak detection?
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.
Do you test for asbestos?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
Leave it or get it looked at?
Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In Hanger Hill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.
