Electronic leak detection in Shenleybury
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. We are often asked to look into breaches hidden under paving or planting and leaking laps in the waterproofing, across single-ply roofs, liquid-applied waterproofing and roof terraces and balconies.
Flat roofs on exposed homes in small places like Shenleybury take more wind and rain, so edges, upstands and laps take a beating. 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. On an exposed roof, the edges tend to go first.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

What affects the price in Shenleybury

What else we do in Shenleybury
How it works
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Shenleybury can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- 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.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Agree roof access with the managing agent if it’s shared
- Move anything stored under the loft hatch
- Have keys ready for side gates, garages or roof access doors
Getting a price
Every survey is priced before it’s booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.
Advice
Why act early in Shenleybury
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Older and listed buildings around Shenleybury may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.

Local flat roofs in Shenleybury
About 4.1 miles east lies Wyllyotts Manor, a reminder of how long the area around Shenleybury has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For landlords with property near Radlett station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a shop, office or commercial unit, for instance near The Maltings, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you live in an older home near St Botolphs, the joins between later flat roofs and the old walls are where problems typically start.

When you need someone else

- Flat roof membranes
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies

Shenleybury questions
Is Shenleybury within the area you cover?
Yes, Shenleybury is on our map. A small place gets exactly the same survey as a big one.
Do you carry out roof surveys in Shenleybury?
We do. Every survey there gets the same written report with photographs.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
What does the report include?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Useful tips for Shenleybury property owners
Nothing here needs a ladder. Our suggestions:
- Ask contractors to protect the membrane
- Share any drawings of the roof
- Test new membranes before covering them
- Avoid repeated repairs without finding the cause
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Make sure contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
