How electronic leak detection works in Watton at Stone
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. If you’ve noticed leaks through a covered membrane and punctures from foot traffic or tools, a survey will tell you what’s going on, whatever the roof.
In a small place like Watton at Stone, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
It is not only a list of defects. It explains what we found, why it matters and what we recommend.

Local flat roofs in Watton at Stone
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around Watton at Stone has a long history of building, with Aston Bury about 2 miles north-west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Take a building like Watton-at-Stone Primary and Nursery School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Watton-At-Stone station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.

FAQs for Watton at Stone
Is Watton at Stone in the area you cover?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will you come out to Watton at Stone?
Yes, we do. We work right across London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
What we can’t see
It’s useful to know what a survey won’t do before you book:
- Parts of the roof covered by fixed equipment
