About our electronic leak detection in Great Canfield
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you’ve noticed breaches around outlets and penetrations and patched roofs that still leak, a survey will tell you what’s going on, on liquid-applied waterproofing, roof terraces and balconies and green roofs alike.
In a village or hamlet like Great Canfield, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Great Canfield, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- We start by finding out what the roof is made of and where it leaks.
- 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
- Leave a clear route to the loft
- Show us where any leaks or stains appear
- Agree roof access with the managing agent if it’s shared

We confirm the price for your survey before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or drop us an email.

Useful tips for Great Canfield property owners
Small things make a difference. Some pointers:
- Ask contractors to protect the membrane
- Share any drawings of the roof
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
If anything in the report is not clear, ask us. We will explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Questions from Great Canfield
Is Great Canfield in the area you cover?
Yes, Great Canfield is within the area we cover. We survey roofs across London and South East England. You can phone 07833 053749 or send us an email with the address and some details, and we’ll talk through which survey suits.
Do you cover smaller places like Great Canfield?
We do. Villages and rural addresses get the same survey as a town house.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
Do you use drones?
Where it helps and it’s 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 hold a CAA Flyer ID and Operator ID.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
Rented homes, blocks and businesses
With a portfolio of properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or send us an email with the addresses.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
What we are asked to look at in Great Canfield
Holes in a membrane frequently come from feet, tools or debris. Some are too small to see, but still let water through.
Problems we come across often include:
- A flat roof leak that cannot be traced
- Leaks showing away from the breach
- Holes around roof penetrations
- Punctures from foot traffic or tools
Landlords with a home close to Stansted Airport station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

What affects the price in Great Canfield
All our prices include VAT. The things that change the price are:
- Chimneys, valleys, parapets and other details
- The number of roofs, including extensions and garages
- If the survey needs thermal imaging or a drone
- House, block, shop or office
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to tell us when you get in touch
A little information up front helps. It’s useful to include:
- The kind of building and roof involved
- What made you get in touch
- Any marks or damp showing indoors
- Photos of the roof, taken safely from the ground or a window
To arrange a survey, call 07833 053749 or send us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.

What electronic leak detection looks like in Great Canfield
Older buildings in Essex often have clay tiles and weatherboarding, and plenty of post-war and modern estates besides. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 2.9 miles west lies Barrington Hall, a reminder of how long the area around Great Canfield has been built on. Older homes in the wider area often 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.
If your home is one of the older ones in the streets near Parish Church of St Mary, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
