Electronic leak detection in Duncton, West Sussex
Electronic leak detection in Duncton from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and the South East.
- Repairs that haven’t stopped the leak
- Breaches hidden under paving or planting
- New roofs to check before paving or planting
Before and after the survey
Nothing here needs a ladder. Our suggestions:
- Let us know about the membrane and build-up if you know it
- Use boards when working on the roof
- Keep foot traffic on flat roofs to a minimum
- Record dates and spots where water appears
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Electronic leak detection in Duncton: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. If you’ve noticed gaps at membrane joints and patched roofs that still leak, a survey will tell you what’s going on.
In a small place like Duncton, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

Different roofs, different checks
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Questions from Duncton
Do you carry out roof surveys in Duncton?
Yes, Duncton is one of the places we work. The survey and report are the same in Duncton as anywhere else, and visits run on weekdays and weekends.
Is my home in Duncton listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Share any details you have and we’ll confirm suitability.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
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.
Electronic leak detection around Duncton
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Bignor Roman Villa, about 2.4 miles south-east, show how far back building in the area around Duncton goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building such as Duncton CofE Junior School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Duncton is about 10 miles north-east of Chichester, in West Sussex. Bookings from Duncton are handled just like any other: a call or an email, a price, then a date. Our West Sussex coverage includes Duncton and the places around it. There’s also a page for Guildford.
Postcode districts we cover here for electronic leak detection: GU28. Local streets include Duncton High Street and Willett Close, all of which we cover. Close by, we survey roofs in East Lavington (1 mile south-west), Sutton (2 miles south-east), Rotherbridge (2 miles north), Graffham (2 miles west) and Haslingbourne (2 miles north-east). Larger places within reach include Worthing (13 miles south-east), Bognor Regis (11 miles south), Chichester (10 miles south-west), Littlehampton (10 miles south-east), Emsworth (15 miles south-west) and Rustington (11 miles south-east).

What electronic leak detection does not cover
It is a careful look at the flat roof membrane, not the whole story. The main limits are:
- Moisture spread under the membrane
- Roofs whose membrane or build-up is not suitable
- Sections we cannot safely access
If you are not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before booking. What a survey covers and does not.
What we look at
- Green roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
Common roof problems in Duncton
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Typical things we are asked to look at include:
- Leaks through a covered membrane
- A flat roof leak that cannot be traced
- Patched roofs that still leak
- Leaking laps in the waterproofing
If you live in an older home near Church of Holy Trinity, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Questions to ask before you book
- How long the report takes to arrive
- What’s outside the scope of the survey
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
What we do, step by step
We do not take risks to get a closer look. We inspect what can be seen safely, and anything we can’t see is noted in the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Duncton can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- 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.
How to prepare
- For flats, check roof access has been agreed
- Have any paperwork from past roof work to hand
- Keep pets in another room
How to book
Getting a price is simple: just call 07833 053749 or email us and give us a few details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
