About our electronic leak detection in Chelwood Gate
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 report with photographs of each breach found. We survey flat roof membranes, green roofs and single-ply roofs, and common reasons people get in touch are leaks through a flat roof with no obvious cause and damp inside with no sign on the roof.
In a village or hamlet like Chelwood Gate, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included as you book.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Limit access to the roof
- Note where leaks show inside and when
- Test new membranes before covering them
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
How it works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Chelwood Gate often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Point out any leaks or damp patches
- Make a note of anything you’d like us to look at
- Leave side gates unlocked
Booking a survey
Photos help, if you have them. Take them safely from ground level or a window, and please do not climb up for a closer look. To send them or to book, call 07833 053749 or drop us an email.

How the survey changes by roof type
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
What this survey cannot tell you
To be straight with you, a roof survey has limits:
- Repairing the breaches (that is for your roofer)
- Leaks from plumbing or windows
- The extent of water in the insulation

Chelwood Gate questions
Do you cover Chelwood Gate?
We do. The survey and report are the same in Chelwood Gate as anywhere else.
Do you cover smaller places like Chelwood Gate?
Yes, we do. We survey roofs across London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
How does ELD work?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Will you walk on the roof?
Not unless it is safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
How quickly is the report sent?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Electronic leak detection in Chelwood Gate: local notes
Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Priest House, about 3.8 miles north-west, is one of the historic houses in the wider area around Chelwood Gate. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If your house is among the older ones in the streets near Chelwood Gate Church, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
