About our electronic leak detection in Chertsey
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. Typical surveys look at stains far from any visible defect and leaks under green or ballasted roofs, across green roofs, flat roof membranes and single-ply roofs.
In smaller places like Chertsey, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. What it is covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Checking the roof from ground level
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
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 look at the roof.
What a survey costs
The price reflects the time and kit the roof needs. That comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
- The height of the building and how the roof can safely be seen
For a price for your roof in Chertsey, ring 07833 053749 or use the contact form and let us know about the roof. We’ll confirm the figure before booking.
Booking your survey
Some details help us recommend the right survey and price. When you contact us, let us know:
- Any stains, drips or damp patches you’ve seen indoors
- Photos of the roof, taken safely from ground level or a window
- When you need the report by
- The style of property, from a terrace to a block
If you’re buying, it is useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.
What we’re asked to look at in Chertsey
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in long before anyone notices.
Look out for signs like these:
- Gaps at membrane joints
- Leaks that return after repairs
- Stains far from any visible defect
- Breaches hidden under paving or planting
Landlords with a home close to Chertsey station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- Their track record with similar roofs
- Whether you get a written report with photos
- What follow-up you get after the report
- Which viewpoints they use to see the roof
What electronic leak detection looks like in Chertsey
About 1.5 miles south-west lies Botleys Mansion, a reminder of how long the area around Chertsey has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Chertsey has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Take a building like St Anne's Catholic Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If your house is among the older ones in the streets near Church of St Peter, the flat roofs on later extensions tend to wear out long before the main roof.

Chertsey: your questions answered
Is my home in Chertsey listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will you come out to Chertsey?
Yes, Chertsey is covered. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What’s the price of ELD?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or drop us an email for a quote.
Do you test for asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
How it works
After the inspection, everything we found is written up as a written report with photos, emailed to you. On timing, it typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. For a survey in Chertsey, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- First, you tell us 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.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- If you are buying, let the agent know when we are coming
- Keep pets out of the way during the survey
- Have any questions written down, so nothing gets missed
How to book
Getting a price is simple: just call 07833 053749 or send us an email, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
Before and after the survey
Here are a few things we’d tell any owner:
- Note where leaks show inside and when
- Check new waterproofing before handover
- Let us know about the membrane and build-up if you know it
- Don’t keep patching the same spot
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

How the survey changes by roof type
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
