How electronic leak detection works in Watersfield
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. We survey single-ply roofs, flat roof membranes and green roofs, and people most often book us about damp inside with no sign on the roof and holes left by work on the roof.
In a small place like Watersfield, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, usually 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.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. Testing helps find them.
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
What happens on the day
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Watersfield can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before the survey
- Gather any invoices or paperwork from past roof work
- Make sure the loft hatch can be reached
- Leave side gates unlocked
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or email us.

Your questions about electronic leak detection in Watersfield
Is Watersfield in the area you cover?
Yes, Watersfield is one of the places we work. The survey and report are the same in Watersfield as anywhere else.
Is my home in Watersfield listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
How is ELD priced?
We quote for each roof individually. Tell us about the roof and where it leaks, and call 07833 053749 or send us an email for a quote.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To arrange a date, ring 07833 053749 or drop us an email.
Do you need to get into the loft?
Normally, if there’s one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.

Tips that help
Most of what helps is simple and safe from ground level. Our suggestions:
- Do not leave water getting in
- Record dates and spots where water appears
- Don’t keep patching the same spot
- Keep foot traffic on flat roofs to a minimum
Questions about the results are welcome. We’ll explain what was found and what it means.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
What electronic leak detection doesn’t cover
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:
- The extent of water in the insulation
- Roofs whose membrane or build-up is not suitable
- Fixing the holes we find
If in doubt, call 07833 053749 or email us and we will recommend the right survey. The full list of what we check.
What we check
- Single-ply roofs
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Roof terraces and balconies
- Flat roof membranes
Checking the roof from the ground
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 ground level.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we look at the roof.
Flat and commercial roofs around Watersfield
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Bignor Roman Villa, about 1.8 miles west, is one of the historic houses in the wider area around Watersfield. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you live in an older home near The Parish Church of St Giles, the flat roofs on later extensions tend to wear out long before the main roof.

When to book a survey in Watersfield
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
It’s worth booking a survey if you’ve seen:
- Damp inside with no sign on the roof
- Gaps at membrane joints
- A flat roof leak that can’t be traced
- Holes left by work on the roof
If you let a flat or house near Pulborough station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Choosing a roof surveyor
- What the report includes, and whether it has photographs
- Whether you can ask questions once you have the report
- Is VAT included in the price?
- Whether the inside of the roof is included
