Electronic Leak Detection in Hertfordshire

Electronic leak detection in Hertfordshire: how it works

Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small 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 can repair them. You get a written report with photos of each breach found. We survey green roofs, commercial flat roofs and liquid-applied waterproofing, and common reasons people get in touch are leaking laps in the waterproofing and damp inside with no sign on the roof.

Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too.

1. We ask about the roof, its age, its membrane and where leaks appear inside.
2. The roof is assessed to see if electronic testing will work on it.
3. The testing method is chosen to suit the membrane and build-up.
4. Testing runs across the roof to locate breaches in the membrane.
5. The breaches are recorded with photos in a report for your roofer.

What you’ll pay

What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Why book with us

• Customer satisfaction of 98%
• Independent findings on the roof’s condition

Useful tips for Hertfordshire property owners

Over many surveys, some simple habits stand out as worth the effort:

• Keep outlets clear of debris
• Get leaks traced quickly
• Check new waterproofing before handover
• Do not keep patching the same spot

If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.

Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
