Electronic Leak Detection in Birchden
Know where you stand with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Birchden.
- Holes around roof penetrations
- Damp inside with no sign on the roof
- Holes left by work on the roof
How it works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photos as we go and record our findings for the written report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Birchden can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Tell us about parking before the day

Electronic leak detection for homes and businesses in Birchden
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We are frequently asked to look into holes around roof penetrations and leaking laps in the waterproofing, across green roofs, flat roof membranes and roof terraces and balconies.
In a small place like Birchden, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, frequently 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Birchden questions
Will you come out to Birchden?
We do. Villages and rural addresses get the same survey as a town house.
Does a conservation area affect roof work in Birchden?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Can you survey in bad weather?
A survey can typically go ahead in light rain. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather is not suitable.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To arrange a date, call 07833 053749 or drop us an email.
What we are asked to look at in Birchden
Holes in a membrane often come from feet, tools or debris. Many are tiny, but still let water through.
A survey can pick up problems such as:
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Leaks showing away from the breach
- Repairs that haven’t stopped the leak
If you look after a building such as Groombridge St Thomas' Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
What to check before booking
- Is there a chance to talk the report through?
- What they will not be able to tell you
- Will they check the loft as well as the outside?
- How long the report takes to arrive
Electronic leak detection around Birchden
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. 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 Groombridge Place, about 0.8 miles north, show how far back building in the area around Birchden goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you look after a shop, office or commercial unit, for example near The Corn Exchange, a flat roof over a business is out of sight and out of mind until it leaks. Take an older house close to Church of St Thomas the Apostle: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Roof area
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages
- If the survey needs thermal imaging or a drone
To find out what your survey will cost, ring 07833 053749 or email us and tell us about the roof. We will confirm the figure before booking.
Getting in touch
Before you get in touch, it’s useful to have:
- Access details, such as a loft hatch or a shared roof
- The type of building and roof, such as pitched or flat
- Photos of the roof, taken safely from the ground or a window
- Your postcode, so we can check access and travel
A quick phone call is typically the easiest start: call 07833 053749 or drop us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.
DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
What we look for on each type of roof
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll tell you if yours isn’t suitable.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Before and after the survey
From years of surveys, a few habits stand out:
- Record dates and spots where water appears
- Do not keep patching the same spot
- Use boards when working on the roof
- Act on new leaks promptly
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
