How electronic leak detection works in Kinsbourne Green
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof can’t be tested. Typical surveys look at holes left by work on the roof and repairs that haven’t stopped the leak, across single-ply roofs, liquid-applied waterproofing and green roofs.
In a small place like Kinsbourne Green, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What electronic leak detection looks like in Kinsbourne Green
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Kinsbourne Green has a long history of building, with Childwickbury Manor about 4.1 miles south-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Take a building like Wood End School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Harpenden station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

Common roof problems in Kinsbourne Green
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Most people get in touch when they’ve noticed something like this:
- Leaks at pipes, outlets or fixings
- Punctures from foot traffic or tools
- Patched roofs that still leak
- Stains far from any visible defect
Shop and office owners around The Mall Luton may find that a flat roof over a business is out of sight and out of mind until it leaks.
Choosing a roof surveyor
- How long they’ve been surveying roofs
- When you will get the report
- What the survey won’t cover
- What insurance they carry
Practical tips
Nothing here needs a ladder. Our suggestions:
- Don’t let outlets block
- Do not keep patching the same spot
- Use boards when working on the roof
- Keep foot traffic on flat roofs to a minimum
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Can I check my roof myself?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.

How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
The survey, step by step
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect as long as needed for the size of the roof and how it’s built, which we set out in the quote. Around Kinsbourne Green, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Check we can get to the back of the property
- Have any questions written down, so nothing gets missed
- Agree roof access with the managing agent if it is shared
