Electronic leak detection in Butcher's Cross, East Sussex
Electronic leak detection to pinpoint holes in flat roof membranes in Butcher's Cross, using drones and thermal imaging where applicable. Call or email for a price.
- Damp inside with no sign on the roof
- A flat roof leak that can’t be traced
- Breaches hidden under paving or planting
How the survey changes by roof type
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
Green and ballasted roofs
ELD is easier on a new roof before it is covered.
How electronic leak detection works in Butcher's Cross
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you’ve noticed holes left by work on the roof and new membranes needing a check before handover, a survey will tell you what’s going on, on single-ply roofs, commercial flat roofs and liquid-applied waterproofing alike.
Somewhere as small as Butcher's Cross, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

When you need someone else
A survey is a careful look at the flat roof membrane, but it cannot do everything. Its limits include:
- Fixing the holes we find
- Moisture spread under the membrane
- Leaks from walls, copings or rooflights

- Flat roof membranes
- Commercial flat roofs
What a survey costs
Prices vary from roof to roof, and it comes down to:
- The shape of the roof and its details
- The roof’s overall size
- Whether it is a home or a commercial building
- Height and safe access
What a survey costs comes down to the roof itself: its size, its height, how many sections it has 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 contact us
Here’s what helps us most when you contact us:
- Pictures from the garden or a window, if you have them
- Access details, such as a loft hatch or a shared roof
- Any deadline, like an exchange date
- What’s prompted the survey
We confirm the price for your survey before booking, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or use the contact form.
How it works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. In a hamlet or village like Butcher's Cross, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- 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.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- For flats, check roof access has been agreed
- Jot down any questions you want answered
- Make sure we can get to the back of the property
Booking a survey
Most bookings start with a short call: ring 07833 053749 or send us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Related advice
What happens if roof problems are left?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye where the roof suits it. In a small place like Butcher's Cross, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.

What electronic leak detection looks like in Butcher's Cross
An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building such as Skippers Hill Manor School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. The streets around a church such as Church of the Good Shepherd are frequently among the oldest in a place, and if your home is one of the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Crowborough station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

FAQs for Butcher's Cross
Is Butcher's Cross in the area you cover?
Yes, Butcher's Cross is one of the places we work. The survey and report are the same in Butcher's Cross as anywhere else.
How do I find out if my home in Butcher's Cross is listed?
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.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Does the weather affect the survey?
Light rain does not usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather is not suitable.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks, and phone 07833 053749 or email us for a quote.
