How we price electronic leak detection

- Roof area
- Extra roofs, like extensions, dormers or garages

Electronic leak detection in Walderton
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. If you are worried about new membranes needing a check before handover and water coming in under a flat roof, a survey will tell you what’s going on, on single-ply roofs, roof terraces and balconies and green roofs alike.
In a village or hamlet like Walderton, flat roofs are typically on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when you book.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What electronic leak detection looks like in Walderton
The coast is about 5 miles or less from Walderton, so there is more wind and more salt in the air than further inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Uppark, about 4.3 miles north, is one of the historic houses in the wider area around Walderton. If your home is older, its flat-roofed extension or dormer may be on its second or third covering. If your house is among the older ones in the streets near The Parish Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Nutbourne station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Common questions in Walderton
Is my home in Walderton listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Does being near the coast affect roofs in Walderton?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Will you check the loft?
If there is a loft and safe access to it, yes. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks. Just call 07833 053749 or email us for a quote.
What’s the best way to book?
Simply call 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
What happens next?
You receive the written report by email, with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you give me structural calculations?
No. We are roof surveyors, not structural engineers, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
What we do, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Walderton can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You tell us about the roof and where water is showing.
- 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 photographs shows where each breach is.
How to prepare
- Jot down any questions you want answered
- Have keys ready for side gates, garages or roof access doors
- For a flat or shared roof, check access with whoever owns or manages the building

Related advice
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.

Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Do not keep patching the same spot
- Don’t let outlets block
- Record dates and spots where water appears
- Check trades protect the waterproofing
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Check contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
