Electronic leak detection in St Leonards: what you get
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It avoids arranging a test that can’t give results. We survey roof terraces and balconies, single-ply roofs and commercial flat roofs, and common reasons people get in touch are patched roofs that still leak and damp inside with no sign on the roof.
Flat roofs on exposed homes in small places like St Leonards take more wind and rain, so edges, upstands and laps take a beating. 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. On an exposed roof, the edges tend to go first.
We keep jargon out of it: if work is needed, the report says so clearly.

FAQs for St Leonards
Does a conservation area affect roof work in St Leonards?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you cover smaller places like St Leonards?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when you book.
Can you inspect my roof with a drone?
Yes, where it’s applicable. 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.
Does ELD work under paving or planting?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when booking.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we’ll confirm suitability.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
What electronic leak detection looks like in St Leonards
The wider area around St Leonards has a long history of building, with Cholesbury Manor House about 1.1 miles east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, 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, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For landlords with property near Wendover station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church like Church of St Leonard are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What you can safely check yourself
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Leave it or get it looked at?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Where a roof is exposed, as many are in small places like St Leonards, driving rain gets into any weakness, and damp in older walls is slow to dry out.
To find out what your survey will cost, call 07833 053749 or drop us an email and tell us about the roof. We’ll confirm the figure before booking.

The survey, step by step
We check the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like St Leonards 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.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
How to prepare

- Tell us where we can park nearby

Tips that help
You do not need to be a roofer to help. What helps most:
- Tell us about the membrane and build-up if you know it
- Consider ELD before paving or planting goes on
- Avoid repeated repairs without finding the cause
- Make sure trades protect the waterproofing
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Roof area
- Extensions, dormers and garages with roofs of their own
- Height and safe access
- Chimneys, valleys, parapets and other details
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Getting in touch
To price your survey accurately, we will ask about:
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
- Where water is showing inside, if it is
- The type of building and roof, like pitched or flat
A quick phone call is normally the easiest start: ring 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
For landlords and managing agents
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
We survey roofs for landlords and letting agents as well as householders. A written report with photographs gives you a clear record of the flat roof membrane, which helps you plan work between tenancies.
