Crockham Hill Electronic Leak Detection
Get a clear view of the flat roof membrane at a property in Crockham Hill from an independent roof surveyor. Visits run on weekdays and weekends, in the daytime.
- New membranes needing a check before handover
- Holes around roof penetrations
- Leaks showing away from the breach
The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Crockham Hill can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Tell us where we can park nearby
- If you’re buying, check with the agent that we can get in
- Unlock side gates and any roof access doors
Book a survey
Getting a price is simple: just call 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Advice
How electronic leak detection works in Crockham Hill
Our ELD report shows where each breach was found, with photographs. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a photo-illustrated written report. If you are worried about new roofs to check before paving or planting and holes left by work on the roof, we can find out what’s behind it, whatever the roof.
Somewhere as small as Crockham Hill, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

What a survey costs
When we price a survey, we consider:
- House, block, shop or office
- The size of the roof
- How tall the building is and how easy the roof is to see
- Features like valleys, chimneys, dormers and parapets
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Booking your survey
These details help when you get in touch:
- Photos of the roof, taken safely from the ground or a window
- Dates you’re working to, such as exchange
- Where the property is, with the postcode
- What made you get in touch
You can call us seven days a week. For a price or to book, phone 07833 053749 or send us an email.
What electronic leak detection looks like in Crockham Hill
With Chartwell about 1 mile north-east, Crockham Hill sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own one of the older houses in the streets near Holy Trinity Church, the joins between later flat roofs and the old walls are where problems usually start. For landlords with property near Edenbridge station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Your questions about electronic leak detection in Crockham Hill
Will you come out to Crockham Hill?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How do I find out if my home in Crockham Hill is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
Will you go up on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Bituminous membranes
ELD is often possible on bituminous membranes though the layers below matter.
Honest limits
Without opening up the roof, some things stay hidden, so a survey has limits:
- Some conductive membranes
- Leaks from plumbing or windows
- Moisture spread under the membrane

What else we do in Crockham Hill
What you can safely check yourself
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
