Signs you need electronic leak detection in Great Bookham
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in for months before it shows.
These are some of the problems a survey can pick up:
- Breaches around outlets and penetrations
- New roofs to check before paving or planting
- Holes left by work on the roof
- Leaks through a covered membrane
If you live in an older home near Church of St Nicolas, the joins between later flat roofs and the old walls are where problems typically start.

Electronic leak detection in Great Bookham: what you get
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for 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. We survey green roofs, liquid-applied waterproofing and single-ply roofs, and common reasons people get in touch are stains far from any visible defect and leaks through a flat roof with no obvious cause.
In smaller places like Great Bookham, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let plenty of water into the room below. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What we look for on each type of roof
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Blocked gutters on homes around Great Bookham overflow and soak walls. It is easy to sort the cause early and slow to dry a damp wall.

Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Polesden Lacey, about 1.6 miles south, is one of the historic houses in the wider area around Great Bookham.

How it works
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. A typical survey takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. For a survey in Great Bookham, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Mention any parking restrictions on your street
- For flats, make sure roof access has been agreed
- Buyers: confirm access with the estate agent or seller
