Electronic leak detection in Clement Street: what you get
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. Common reasons to book are leaks through a flat roof with no obvious cause and leaking laps in the waterproofing, on roof terraces and balconies, liquid-applied waterproofing and flat roof membranes.
Older buildings in small places like Clement Street may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Where we can’t see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Flat and commercial roofs around Clement Street
Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Hall Place and Gardens, about 3.3 miles north-west, is one of the historic houses in the wider area around Clement Street. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
The streets around a church such as Church of Saint Paul are often among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Farningham Road station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
Clement Street is about 2 miles south of Dartford, in Kent. In Clement Street, as across Kent, every roof gets the same careful survey. Clement Street is one of the places in Kent we cover for electronic leak detection. Our London page covers surveys nearby.

Common roof problems in Clement Street
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in for months before it shows.
We are often asked to look at:
- Holes left by work on the roof
- Leaks through a covered membrane
- Patched roofs that still leak
- Water coming in under a flat roof
Anyone responsible for a site like Sutton-At-Hone Church of England Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Questions from Clement Street
Is my home in Clement Street listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Clement Street within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route as you book.
Does ELD include fixing the breach?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Do you use drones?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Why get it checked now?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. For an older or listed building in a place like Clement Street, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the exact price before you book.

- Roof terraces and balconies
- Single-ply roofs
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Liquid-applied waterproofing
Checking the roof from ground level
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
What we do, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. Somewhere like Clement Street needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Find any records of previous roof work
- Make sure the loft hatch can be reached
- Buyers: confirm access with the estate agent or seller
Booking a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or email us when you’re ready.
