How electronic leak detection works in High Cross
We carry out electronic leak detection on flat roofs in High Cross and across London and the South East. A visit typically takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. Common reasons to book are repairs that haven’t stopped the leak and leaking laps in the waterproofing, across flat roof membranes, green roofs and commercial flat roofs.
Flat roofs on exposed homes in small places like High Cross take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.

Electronic leak detection in High Cross: local notes
Wadhurst Castle, about 4.9 miles east, is one of the historic houses in the wider area around High Cross. 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. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs, and the county’s older buildings include oast houses and Wealden hall houses. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If yours is one of the older homes in the streets near The Parish Church of St Denys, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Landlords with a home close to Crowborough station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
High Cross is about 3 miles east of Crowborough, in East Sussex. If you are in High Cross, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day. We cover towns and villages across East Sussex. Crawley is in our area too.

Your questions about electronic leak detection in High Cross
Is my home in High Cross listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Is High Cross in the area you cover?
Yes. We survey roofs across London and the South East, and High Cross is part of that. You can call 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof. Just ring 07833 053749 or drop us an email for a quote.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Can you survey in bad weather?
Light rain is usually fine; heavy rain and wind are different. In strong wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
Does electronic leak detection work on all membranes?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours isn’t suitable before testing.
What we are asked to look at in High Cross
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Here are some of the things we see often:
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
- Holes around roof penetrations
- Patched roofs that still leak
For site and facilities teams at buildings like Rotherfield Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

- Will the report include photos?
- Which limits apply to the survey
- Whether the price includes VAT
What happens if roof problems are left?
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
To find out what your survey will cost, ring 07833 053749 or send us an email with the address and a few details. We’ll confirm the figure before booking.

What we do, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take a length of time set by the roof’s area and construction, which we set out in the quote. Somewhere like High Cross needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- 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.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Agree roof access with the managing agent if it’s shared
- Leave side gates unlocked
- Gather any invoices or paperwork from past roof work
Arrange a survey
If you’re buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or use the contact form whenever suits you.
Advice
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- The height of the building and how the roof can be seen safely
- The shape of the roof and its details
- How many separate roofs there are, like extensions, dormers and garages
- How big the roof is
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before you book.
Helping us price your survey
Before you get in touch, it is useful to have:
- Where the property is, with the postcode
