Different roofs, different checks
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Electronic leak detection in Margery
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. If neither method suits your roof, we will tell you before any testing starts. We are often asked to look into water coming in under a flat roof and holes around roof penetrations, across roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs.
In a village or hamlet like Margery, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Common questions in Margery
Do you cover Margery?
Yes, Margery is within the area we cover. Our area covers London and South East England. You can call 07833 053749 or email us with the address and some details.
Does a conservation area affect roof work in Margery?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you use low-voltage or high-voltage testing?
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.
Will you go up on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and call 07833 053749 or use the contact form for a quote.
How we price electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can be seen safely
- The size of the roof
- Whether thermal imaging or a drone is needed
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.
Helping us price your survey
If you can, have these to hand when you contact us:
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
- What’s prompted the survey
- When you need the report by
Photos help, if you have them. Take them safely from the ground or a window. To send them or to book, phone 07833 053749 or send us an email.
How it works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a hamlet or village like Margery, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- Jot down any questions you want answered
- Let us know about any leaks, stains or damp patches you know of
- If you are buying, check with the agent that we can get in
Arrange a survey
Every survey is priced before it is booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, call 07833 053749 or drop us an email.

Local flat roofs in Margery
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Before planning roof work on an older home, find out whether it is listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
For site and facilities teams at buildings such as Kingswood Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For businesses in and around places such as The Belfry, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

When to book a survey in Margery
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
It is worth booking a survey if you’ve seen:
- Breaches hidden under paving or planting
- Holes left by work on the roof
- Damp inside with no sign on the roof
- Water coming in under a flat roof
If you live in an older home near Church of Jesus Christ and the Wisdom of God, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Questions to ask before you book
