Electronic Leak Detection in Horns Green
Electronic leak detection across Horns Green, backed by more than 20 years’ experience. Every survey ends with a written report and photographs.
- Leaks through a flat roof with no obvious cause
- Holes left by work on the roof
- Gaps at membrane joints
Useful tips for Horns Green property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep a note of leaks after rain
- Keep foot traffic on flat roofs to a minimum
- Consider ELD before paving or planting goes on
- Don’t keep patching the same spot
Questions about the results are welcome. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
About our electronic leak detection in Horns Green
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you’ve noticed holes around roof penetrations and failed seams and laps, a survey will tell you what’s going on.
Flat roofs on exposed homes in small places like Horns Green 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.
Findings are set out part by part, from the coverings down to the gutters. You’ll see the good as well as the bad.

What electronic leak detection looks like in Horns Green
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Down House, about 2.1 miles north-west, show how far back building in the area around Horns Green goes. 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.
If your house is among the older ones in the streets near Church of St Peter and St Paul, the joins between later flat roofs and the old walls are where problems typically start. For site and facilities teams at buildings like Charles Darwin School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Why it’s worth a survey now in Horns Green
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. Outbuildings and barns around Horns Green are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Why us?
- Surveys seven days a week
- Customer satisfaction of 98%
- Drone and thermal imaging surveys available
- Independent findings on the roof’s condition
What we do, step by step
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Older rural homes like those around Horns Green can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Keep pets out of the way during the survey
- Point out any leaks or damp patches
- Have keys ready for side gates, garages or roof access doors

Your questions about electronic leak detection in Horns Green
Is my home in Horns Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Horns Green within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Can you find leaks on a covered flat roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
What’s the best way to book?
To book, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Will you walk on the roof?
Only where it is safe to do so. We look at everything that can be seen safely: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. Anything we can’t see is noted in the report.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Will you check the loft?
Normally, if there’s one and it can be reached safely. The roof space can show things the outside cannot, like damp timbers, staining or daylight.
Do you need electronic leak detection in Horns Green?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Signs worth acting on include:
- Stains far from any visible defect
- Leaks under green or ballasted roofs
- Gaps at membrane joints
- Leaks that return after repairs
For landlords with property near Knockholt station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before you book
- Whether the price includes VAT
- Their track record with similar roofs
- What’s outside the scope of the survey
- Whether any drone flown is registered with the CAA
Checking the roof from ground level
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
