Electronic leak detection in Wisley, Surrey
A careful look at the flat roof membrane at your property in Wisley, and put it all in a written report with photos.
- Leaks through a flat roof with no obvious cause
- Breaches hidden under paving or planting
- Damp inside with no sign on the roof
Electronic leak detection in Wisley
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. Electronic leak detection tests the membrane itself and locates the breach. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey green roofs, single-ply roofs and flat roof membranes, and common reasons people get in touch are damp inside with no sign on the roof and water coming in under a flat roof.
Somewhere as small as Wisley, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when you book.
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.

What we do, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Wisley, the journey is planned in advance: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Preparing for the visit
- Find any records of previous roof work
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller
How to book

Common roof problems in Wisley
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs, depending on the build-up.
A survey makes sense if you’ve noticed:
- Patched roofs that still leak
- Water coming in under a flat roof
- Leaks through a covered membrane
- Failed seams and laps
Anyone responsible for a site like St Mary's CofE Controlled Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Choosing a roof surveyor

- How soon the report will arrive

What electronic leak detection looks like in Wisley
Byfleet Manor, about 0.8 miles north-east, is one of the historic houses in the wider area around Wisley. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For businesses in and around places such as The Peacocks, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you let a flat or house near West Byfleet station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Wisley is about 4 miles south of Weybridge, in Surrey. Wisley is part of the area we cover and the surrounding area across London and South East England. Our area takes in places right across Surrey. Our Guildford page covers surveys nearby.

What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- Extra roofs, like extensions, dormers or garages
- The use of thermal imaging or a drone
- How big the roof is

Your questions about electronic leak detection in Wisley
Do you carry out roof surveys in Wisley?
We do. Every survey there gets the same written report with photographs.
Will you come out to Wisley?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you look in the loft space?
Usually, if there is one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
How much time does ELD need?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
How do I arrange electronic leak detection in Wisley?
To arrange a survey, phone 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
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, ready to forward.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. In a small place like Wisley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.

Practical tips
You don’t need to be a roofer to help. What helps most:
- Don’t let outlets block
- Check new waterproofing before handover
- Do not keep patching the same spot
- Get leaks traced quickly
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
When you need someone else
Before you book, it is worth knowing what a survey will not do:
- Water entering through details rather than the membrane
- How wet the insulation is
- Roofs whose membrane or build-up isn’t suitable
