Electronic leak detection for homes and businesses in Upperton
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. If you’ve noticed leaks under green or ballasted roofs and new roofs to check before paving or planting, we can find out what’s behind it, on roof terraces and balconies, green roofs and liquid-applied waterproofing alike.
Flat roofs on exposed homes in small places like Upperton take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

What this survey can’t tell you
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Moisture spread under the membrane
- Fixing the holes we find

Upperton: your questions answered
Does a conservation area affect roof work in Upperton?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is Upperton in the area you cover?
Yes, Upperton is within the area we cover. We survey roofs across London and South East England. You can call 07833 053749 or email us with the address and a few details.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs, and 98% of clients are satisfied.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Can you find leaks on a covered flat roof?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We talk this through first.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Does the weather affect the survey?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather isn’t right.
How the survey works
Every roof is different; as a rough guide, the survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. You’re welcome to ask questions while we’re there. Around Upperton, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Make sure pets are kept safely away
- Have any questions written down, so nothing gets missed

Local flat roofs in Upperton
Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 1.2 miles south-east lies Petworth House, a reminder of how long the area around Upperton has been built on. Older homes in the wider area frequently have features worth a closer look, like 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.
Upperton is about 12 miles north-east of Chichester, in West Sussex. We survey roofs in Upperton as part of our work across London and the South East. Upperton is one of the places in West Sussex we cover. We also survey roofs in Guildford.

Checking the roof from ground level
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Do you need electronic leak detection in Upperton?
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Look out for signs like these:
- Damp inside with no sign on the roof
- Failed seams and laps
- Leaks under green or ballasted roofs
- Leaks through a flat roof with no obvious cause
Take an older house close to The Parish Church of All Hallows: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Choosing a roof surveyor
- What exactly goes into their report
- Which parts of the roof they’ll actually see
- Whether you can ask questions once you have the report
- Whether any drone flown is registered with the CAA

What affects the cost of electronic leak detection
The price reflects the time and kit the roof needs. The main factors are:
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

- Whether there is a loft hatch, a shared roof or tricky access
