Electronic leak detection in Blackbird Leys: what you get
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey green roofs, commercial flat roofs and liquid-applied waterproofing, and people most often book us about stains far from any visible defect and breaches hidden under paving or planting.
Around a smaller place like Blackbird Leys, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

Tips from our surveys
These tips come from what we see on roofs every week:
- Stay off the flat roof unless needed
- Keep outlets clear of debris
- Do not leave water getting in
- Record dates and spots where water appears
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Honest limits
In fairness, a roof survey has limits:
- The extent of water in the insulation
- Leaks from walls, copings or rooflights
- Build-ups without a suitable layer below

What happens on the day
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a smaller place like Blackbird Leys, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can frequently be seen well from ground level, and the loft shows the rest.

Common questions in Blackbird Leys
Do you look at commercial flat roofs near Blackbird Leys, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Do you cover smaller places like Blackbird Leys?
Yes. Blackbird Leys is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Will you repair the leak?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Will you go up on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. We check the parts we’re given access to, and the report makes that clear.
