Electronic leak detection in Elephant and Castle, Greater London
Find out what’s going on with the flat roof membrane before you decide what to do next. Electronic leak detection in Elephant and Castle, with photos and a clear written report.
- New roofs to check before paving or planting
- Holes left by work on the roof
- Water coming in under a flat roof
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Check new waterproofing before handover
- Do not leave water getting in
- Record dates and spots where water appears
- Tell us about the membrane and build-up if you know it
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
About our electronic leak detection in Elephant and Castle
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. We survey single-ply roofs, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are damage from equipment installers and stains far from any visible defect.
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 Elephant and Castle, 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Common questions in Elephant and Castle
Is my home in Elephant and Castle listed or in a conservation area?
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.
Do you cover commercial flat roofs around Elephant and Castle?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building.
What happens after the survey?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
Will you walk on the roof?
Only where it is safe to do so. We inspect what can be seen safely: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Roof by roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
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.
How it works
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. 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 Elephant and Castle runs like any other.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
- Tell us about parking before the day
Getting a price
Photos help, if you have them. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or use the contact form.
Advice
Local flat roofs in Elephant and Castle
There are several hotels within about a mile and a half of Elephant and Castle. If you look after one, a leak through a flat roof can put a room out of use. With Benjamin Franklin House about 1.3 miles north-west, Elephant and Castle sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Landlords with a home close to Elephant & Castle station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Take a building like London College of Communication: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What affects the price in Elephant and Castle
Every roof is different, so prices are confirmed before booking. This is what makes a difference:

All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.

A few details help us recommend the right survey and price. When you contact us, it’s useful to mention:
- Any marks or damp showing indoors
- The property’s address and postcode
- Your timetable, such as an exchange date

Why act early in Elephant and Castle
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
