Electronic Leak Detection in Capstone
Electronic leak detection to pinpoint holes in flat roof membranes in Capstone, using drones and thermal imaging where it applies. Call or email for a price.

Common roof problems in Capstone
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Here are some of the things we see frequently:
- Breaches hidden under paving or planting
- Patched roofs that still leak
- Gaps at membrane joints
- Punctures from foot traffic or tools
Shop and office owners around Pentagon Shopping Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Before you book anyone
- How long they’ve been surveying roofs
- Is there a chance to talk the report through?
- Will the report include photos?
- Whether the roof space is looked at, where there is one
About our electronic leak detection in Capstone
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. If you’re worried about holes around roof penetrations and water coming in under a flat roof, we can find out what’s behind it.
Older buildings in small places like Capstone may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later.

What you can safely check yourself
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Why it’s worth a survey now in Capstone
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Where a roof is exposed, as many are in small places like Capstone, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Why book with us
- More than 5,000 surveys completed
- Over 20 years’ experience
- Visits on any day of the week
- CAA-registered drone operator (Flyer ID and Operator ID)

Local flat roofs in Capstone
The coast is about 3 miles or less from Capstone, and places near the sea get more salt in the air and more wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For an older house near a landmark like All Saints Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a building like Hempstead Infant School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Landlords, agents and block managers in Capstone
Letting agents can arrange access with tenants, at a time agreed beforehand. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
How the survey works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take as long as needed for the membrane area and the build-up, which we set out in the quote. In a hamlet or village like Capstone, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- 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.
Before the survey
- Move anything stored under the loft hatch
- If it is not your property yet, arrange access through the agent
- Keep pets out of the way during the survey

Advice
Capstone questions
Do roofs near the sea, like those around Capstone, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it usually shows, and Capstone is within about 3 miles of the coast.
Does a conservation area affect roof work in Capstone?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we will say so at the start.
Do you cover Capstone for electronic leak detection?
Yes. We cover Capstone and the rest of Medway, as part of our work across London and South East England. For a price, call 07833 053749 or send us an email.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Will you repair the leak?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
