Electronic leak detection in Stone, Kent
We carry out electronic leak detection in Stone and the rest of Kent. We survey on any day of the week.
- Stains far from any visible defect
- Leaks under green or ballasted roofs
- Failed seams and laps
What we do, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will take it from there. The survey itself takes a time that depends on the size of the roof and how it’s built, and we’ll give you a guide when quoting. A visit to Stone is planned like any other: the time, the access and where to park are agreed ahead of time. Weekday and weekend visits are both possible. Tell us about any garages, outbuildings or extensions you want included.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
How to prepare
- Note where any stains or damp appear
- Have any paperwork from past roof work to hand
- Mention any parking restrictions on your street

How electronic leak detection works in Stone
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. We are often asked to look into damp inside with no sign on the roof and new membranes needing a check before handover, on green roofs, flat roof membranes and liquid-applied waterproofing.
Outbuildings, garden rooms and garages in places like Stone frequently have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It’s worth mentioning them when booking, so the visit can include them, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

Electronic leak detection around Stone
Stone is within about 5 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. 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. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
With Hall Place and Gardens about 4.8 miles west, the area around Stone has a long history. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan. The streets around a church such as Church of St Mary are often among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems typically start.
Stone is about 2 miles east of Dartford, in Kent. Wherever you are in Stone, we can come and survey your property, on a weekday, Saturday or Sunday. Stone is one of the places in Kent we cover for electronic leak detection. We also survey roofs in London.
Surveys in DA9 are booked the same way as anywhere else. We cover properties on Church Road, Perkins Close and Richardson Close. Being close to the A296, Stone is easy for us to reach for electronic leak detection. If you’re just outside Stone, we cover Greenhithe (1 mile north-east), Swanscombe (1 mile east), Bean (2 miles south-east), Darenth (2 miles south) and Temple Hill (2 miles west). Further out, we also cover Sevenoaks (12 miles south), Gravesend (5 miles east), Northfleet (3 miles east), Swanley (5 miles south-west), Kings Hill (13 miles south-east) and Windmill Hill (4 miles east).

Landlords, agents and block managers in Stone
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we will plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
FAQs for Stone
Is the coastal weather around Stone hard on roofs?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Does a conservation area affect roof work in Stone?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is this an asbestos survey?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
How much time does ELD need?
It typically takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting.
Will you go up on the roof?
Only if it is safe. We inspect what can safely be seen: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.

Other services in Stone
What we look for on each type of roof
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Do not leave water getting in
- Don’t keep patching the same spot
- Stay off the flat roof unless needed
- Consider ELD before paving or planting goes on
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
What we are asked to look at in Stone
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Typical things we are asked to look at include:
- Failed seams and laps
- Waterproofing to test before it is covered
- Water coming in under a flat roof
- Breaches hidden under paving or planting
For site and facilities teams at buildings such as Stone St Mary's CofE Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Choosing a roof surveyor
- Whether the price includes VAT
- Their report turnaround times
- Whether you get a written report with photos
- How they’ll see the roof: from ground level, the loft, the roof or by drone
What electronic leak detection doesn’t cover
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- Fixing the holes we find
- How wet the insulation is
- Some conductive membranes
