How electronic leak detection works in Sandy Balls
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at 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. We survey roof terraces and balconies, flat roof membranes and green roofs, and common reasons people get in touch are stains far from any visible defect and punctures from foot traffic or tools.
Flat roofs on exposed homes in small places like Sandy Balls take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Limit access to the roof
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
- Make sure trades protect the waterproofing
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Why get it checked now?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Sandy Balls: your questions answered
Do you cover Sandy Balls?
Yes. Our area covers London and South East England, and Sandy Balls is part of that. Just call 07833 053749 or email us and tell us about the property.
Do you cover smaller places like Sandy Balls?
Yes, we do. Our area covers London and South East England, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we will check whether ELD will work.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
Are you structural engineers?
No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Can you survey in bad weather?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather is not suitable.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just phone 07833 053749 or drop us an email for a quote.
Flat and commercial roofs around Sandy Balls
Breamore House, about 2.9 miles north, is one of the historic houses in the wider area around Sandy Balls. Older homes in the wider area often 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. Thatch survives on some older buildings in Hampshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Anyone responsible for a site like The Burgate School and Sixth Form will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Should I look at the roof myself first?
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
What we’re asked to look at in Sandy Balls
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Here are some of the things we see often:
- Damp inside with no sign on the roof
- New membranes needing a check before handover
- Leaks at pipes, outlets or fixings
- Leaks through a flat roof with no obvious cause
Take an older house close to St Giles: the joins between later flat roofs and the old walls are where problems typically start.
Before you book any roof surveyor
- Whether the loft is part of the inspection
- What the report includes, and whether it has photographs
- How long the report takes to arrive
- How they’ll see the roof: from the ground, the loft, the roof or by drone
What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Sandy Balls, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Keep pets in another room
- Let us know about parking before the day
- Move anything stored under the loft hatch
How to book
If you have photos of the roof, send them over. Take them safely from the ground or a window. To get started, ring 07833 053749 or drop us an email.
