Electronic leak detection in Gants Hill, Greater London
We take a careful look at the flat roof membrane at your property in Gants Hill, with photos and a written report.
- Failed seams and laps
- Breaches hidden under paving or planting
- Damage from equipment installers
Useful tips for Gants Hill property owners
A survey works best with a little help from you, before and after. Tips:
- Clear flat roof outlets regularly
- Limit access to the roof
- Ask contractors to protect the membrane
- Avoid repeated repairs without finding the cause
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Electronic leak detection for homes and businesses in Gants Hill
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. Typical surveys look at water coming in under a flat roof and holes left by work on the roof, on commercial flat roofs, green roofs and single-ply roofs.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Gants Hill, the roof above may belong to the building rather than one flat.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Surveys for landlords and agents in Gants Hill
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on weekdays and at weekends, which helps when tenants work during the week.
Businesses and commercial landlords can book us too. Larger roofs take longer, and they’re priced for the size.

How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes longer on a large 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 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 confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Getting ready for the survey
- If it is not your property yet, arrange access through the agent
- Let us know about parking near the property
- Keep pets inside or away from the areas we are looking at

Do you need electronic leak detection in Gants Hill?
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in for months before it shows.
Common reasons to book include:
- Leaks through a covered membrane
- Gaps at membrane joints
- Holes left by work on the roof
- Holes around roof penetrations
For site and facilities teams at buildings like Gearies Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book any roof surveyor
- What the survey will not cover
- Whether the price includes VAT
- What the report includes, and whether it has photos
- Whether the inside of the roof is included
Common questions in Gants Hill
Does a conservation area affect roof work in Gants Hill?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Gants Hill?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance.
Which method do you use?
The roof decides the method. We’ll explain why when we quote.
Can you find leaks on a covered flat roof?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We talk this through first.
Will I get photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
Do you test for asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Why get it checked now?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. In Gants Hill, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
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.
Why book with us
- Photographs and a written report every time
- Surveys seven days a week
- Thermal imaging and drones used where they help
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID

What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Flat roofs in Gants Hill
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. 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. With Valentines Mansion about 0.4 miles south-west, Gants Hill 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 a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to St George's Church: the flat roofs on later extensions tend to wear out long before the main roof. If you run a hotel or guest house in or near Gants Hill, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition.
