Electronic leak detection in Batchworth: what you get
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll tell you before any testing. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that cannot give results. If you’ve noticed water coming in under a flat roof and holes left by work on the roof, a survey will tell you what’s going on.
Flat roofs on exposed homes in small places like Batchworth take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Don’t keep patching the same spot
- Don’t let outlets block
- Act on new leaks promptly
- Make sure trades protect the waterproofing
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
Questions from Batchworth
Do you carry out roof surveys in Batchworth?
Yes. We cover the whole of London and South East England, and Batchworth is part of that. You can call 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Batchworth?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
What’s the best way to book?
The quickest way is to call 07833 053749 or send us an email. Give us the address and some details about the roof, and we will recommend the right survey. We survey on any day of the week.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Do you need electronic leak detection in Batchworth?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
These are some of the problems a survey can pick up:
- Leaks that return after repairs
- New roofs to check before paving or planting
- Leaks through a flat roof with no obvious cause
- Leaks through a covered membrane
If you let a flat or house near Rickmansworth station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Before you book any roof surveyor
- Whether the inside of the roof is included
- What follow-up you get after the report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether VAT is added on top

Electronic leak detection in Batchworth: local notes
Chenies Manor House, about 4.4 miles north-west, is one of the historic houses in the wider area around Batchworth. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If yours is one of the older homes in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. If you run a business near Charter Place, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and make notes for the report. It normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Batchworth can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare
- Leave a clear route to the loft
- For flats, make sure roof access has been agreed
- Check we can get to the back of the property

Advice
Why it is worth a survey now in Batchworth
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. For older village homes like those around Batchworth, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
