Electronic leak detection for homes and businesses in Marden Thorn
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. If your roof isn’t suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that cannot give results. If you’re worried about patched roofs that still leak and new roofs to check before paving or planting, we can find out what’s behind it.
Flat roofs on exposed homes in small places like Marden Thorn take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Marden Thorn questions
Does a conservation area affect roof work in Marden Thorn?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Marden Thorn within the area you cover?
Yes, we do. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Do you climb onto every roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where applicable.
What this survey cannot tell you
Every survey has limits, and it is better to know them up front. Keep these in mind:
- How wet the insulation is
- Leaks from walls, copings or rooflights
- Build-ups without a suitable layer below
Not sure which survey suits your roof? You can phone 07833 053749 or email us and we’ll tell you before booking. What a survey covers and doesn’t.
What this survey covers
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
How the survey works
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely. The survey usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Marden Thorn, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- 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.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Before the survey
- Leave side gates unlocked
- Keep pets out of the way during the survey
- Mention any parking restrictions on your street
How to book
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.

Tips that help
Nothing here needs a ladder. Our suggestions:
- Get leaks traced quickly
- Keep outlets clear of debris
- Record dates and spots where water appears
- Share any drawings of the roof
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Flat roofs in Marden Thorn
If your home is older, it’s worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Around Marden Thorn, as everywhere, small roof faults are simplest to sort before they let water in.

What else we do in Marden Thorn
Do you need electronic leak detection in Marden Thorn?
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
These are some of the problems a survey can pick up:
- Holes around roof penetrations
- A flat roof leak that cannot be traced
- Repairs that haven’t stopped the leak
- New roofs to check before paving or planting
If you own a rental within reach of Marden station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking anyone
- Is there a chance to talk the report through?
- Will they check the loft as well as the outside?
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Will the report include photos?
