How electronic leak detection works in Batchworth Heath
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that cannot give results. Typical surveys look at gaps at membrane joints and breaches hidden under paving or planting, across roof terraces and balconies, single-ply roofs and green roofs.
Older buildings in small places like Batchworth Heath may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Why act early in Batchworth Heath
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. For older village homes like those around Batchworth Heath, the right replacement materials are not always easy to find quickly. That is one more reason to find defects before they become urgent.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection around Batchworth Heath
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 4.1 miles south lies Ickenham Hall, a reminder of how long the area around Batchworth Heath has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Rickmansworth station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church such as Holy Trinity Church are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems normally start.

What we are asked to look at in Batchworth Heath
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
Signs worth acting on include:
- Failed seams and laps
- New membranes needing a check before handover
- Repairs that haven’t stopped the leak
- Leaks under green or ballasted roofs
If you look after a building such as Holy Trinity CofE Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Questions from Batchworth Heath
Is Batchworth Heath in the area you cover?
Yes, Batchworth Heath is within the area we cover. We work right across London and South East England. Just ring 07833 053749 or drop us an email and let us know about the property.
How do I find out if my home in Batchworth Heath is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface and high-voltage methods need the membrane dry and exposed.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. Where a material might contain it, such as 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 is disturbed.
How do I arrange electronic leak detection in Batchworth Heath?
Simply call 07833 053749 or drop us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.

How the survey changes by roof type
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
The survey, step by step
The aim of the visit is simple: 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. The visit normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Batchworth Heath, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- 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.
Before the survey
- For flats, make sure roof access has been agreed
- If it isn’t your property yet, arrange access through the agent
- Let us know about any leaks, stains or damp patches you know of

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Consider ELD before paving or planting goes on
- Act on new leaks promptly
- Do not keep patching the same spot
- Keep outlets clear of debris
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
