Bisham Electronic Leak Detection
A careful look at the flat roof membrane at your property in Bisham, with photos and a written report.
- Punctures from foot traffic or tools
- Leaks through a flat roof with no obvious cause
- Leaks showing away from the breach
How it works
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Bisham often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Clear the way to the loft hatch
- Have keys ready for side gates, garages or roof access doors
- If you’re buying, let the agent know when we’re coming
How to book
A quick phone call is usually the easiest start: ring 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.

About our electronic leak detection in Bisham
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you’ve noticed leaking laps in the waterproofing and leaks at pipes, outlets or fixings, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like Bisham take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

Leave it or get it looked at?
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. In a place like Bisham, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Bisham questions
Do you cover commercial flat roofs around Bisham?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Do you cover smaller places like Bisham?
Yes, we do. We work right across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us when you book.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely.
What happens after the survey?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
What we look for on each type of roof
Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Electronic leak detection around Bisham
Historic houses like Harleyford Manor, about 1.5 miles west, show how far back building in the area around Bisham goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Some villages in Buckinghamshire still have thatched roofs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to Marlow station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. For hotels and guest houses around Bisham, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. Take an older house close to Church of All Saints: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, call 07833 053749 or email us.
Can I check my roof myself?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What electronic leak detection doesn’t cover
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Build-ups without a suitable layer below
- How wet the insulation is
- Leaks from plumbing or windows
