Electronic Leak Detection in Cowden
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Cowden.
- Damp inside with no sign on the roof
- Gaps at membrane joints
- Patched roofs that still leak
The survey, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. For a village or hamlet like Cowden, the journey is planned ahead of time: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Keep pets out of the way during the survey
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed

Electronic leak detection in Cowden
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll 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. Our report keeps that distinction clear. We’ll point you to the likely next step. Typical surveys look at leaks at pipes, outlets or fixings and breaches hidden under paving or planting, across green roofs, roof terraces and balconies and commercial flat roofs.
Some older homes in villages like Cowden are listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

Signs you need electronic leak detection in Cowden
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Look out for signs like these:
- New roofs to check before paving or planting
- Failed seams and laps
- Water coming in under a flat roof
- Leaks under green or ballasted roofs
For landlords with property near Cowden station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Choosing a roof surveyor
- Will they check the loft as well as the outside?
- Is there a chance to talk the report through?
- When you’ll get the report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
Why get it checked now?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. In a small place like Cowden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before you book.
Why book us in Cowden
- Visits on any day of the week
- Thermal imaging and drone inspection where they help
- Photos and a written report every time
- Covered by professional indemnity and public liability insurance

What else we do in Cowden
What electronic leak detection looks like in Cowden
Historic houses such as Bassetts Manor, about 1.7 miles south, show how far back building in the area around Cowden goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If your home is one of the older ones in the streets near Church of St Mary Magdalene, flat-roofed rear additions and dormers added over the years are worth checking.

- How complicated the roof is, with its valleys, chimneys and parapets

Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

Questions from Cowden
Do you cover smaller places like Cowden?
Yes, Cowden is covered. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you cover Cowden?
Yes, Cowden is one of the places we work. The survey and report are the same in Cowden as anywhere else, and visits run on weekdays and weekends.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
How much time does ELD need?
Testing usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Do you take photos of the roof?
Yes. Photographs are part of every report.
How soon will I get the report?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when booking.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
DIY checks: what’s safe
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Tips that help
You don’t need to be a roofer to help. Here’s what helps most:
- Share any drawings of the roof
- Find the breach before more patching
- Check new waterproofing before handover
- Record dates and spots where water appears
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
