Electronic leak detection in Crouch, Kent
A careful look at the flat roof membrane at your property in Crouch, with photographs and a written report.
- Breaches around outlets and penetrations
- Damp inside with no sign on the roof
- Leaks that return after repairs
How electronic leak detection works in Crouch
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. We’ll tell you if we think the leak is coming from somewhere else. 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 are often asked to look into patched roofs that still leak and damage from equipment installers, across liquid-applied waterproofing, single-ply roofs and commercial flat roofs.
In a small place like Crouch, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

DIY checks: what’s safe
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

Signs you need electronic leak detection in Crouch
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Common reasons to book include:
- Water coming in under a flat roof
- New membranes needing a check before handover
- Repairs that haven’t stopped the leak
- Breaches around outlets and penetrations
If you live in an older home near Church of St Mary, the flat roofs on later extensions tend to wear out long before the main roof.
Before booking anyone
- How soon the report will arrive
- How much experience they have with roofs like yours
- Whether any drone flown is registered with the CAA
- Whether you can ask questions once you have the report
How we price electronic leak detection
Several things affect the price of a survey:
- If the survey needs thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- How big the roof is
- The shape of the roof and its 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 safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you get in touch
A little information up front helps. Please include:
- Why you want a survey: buying, a leak, a storm or new work
- The style of property, from a terrace to a block
- The property’s address and postcode
- Any deadline, such as an exchange date
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, call 07833 053749 or email us.
What we look for on each type of roof
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Electronic leak detection in Crouch: local notes
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 1 mile south lies Old Soar Manor, a reminder of how long the area around Crouch has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof.
Take a building like Borough Green Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Borough Green & Wrotham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Crouch is about 6 miles east of Sevenoaks, in Kent. In Crouch, as across Kent, every roof gets the same careful survey. Our area takes in places right across Kent. Our Maidstone page covers surveys nearby.

Questions from Crouch
Is my home in Crouch listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Crouch?
Yes. Our area covers London and South East England, and Crouch is part of that. Just ring 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
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.
Do you climb onto every roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
Are you structural engineers?
No. Our survey is not a structural engineer’s report, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
How the survey works
After the inspection, everything we found is written up in a report with photographs. As for time on site, it typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Crouch, older homes can have small or awkward roof spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- If it isn’t your property yet, arrange access through the agent
- Mention any parking restrictions on your street

Practical tips
A little preparation and a few simple habits help. Our tips:
- Do not let outlets block
- Test new membranes before covering them
- Check trades protect the waterproofing
- Get leaks traced quickly
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
