Electronic Leak Detection in Wennington
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Wennington and across Greater London, with plain-English findings.
- A flat roof leak that can’t be traced
- Breaches hidden under paving or planting
- Repairs that haven’t stopped the leak
Electronic leak detection in Wennington
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing is not possible, we will say so. If you are worried about new roofs to check before paving or planting and leaks through a covered membrane, we can find out what’s behind it, on green roofs, roof terraces and balconies and liquid-applied waterproofing alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Wennington, the roof above may belong to the building rather than one flat.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Wennington questions
Is parking a problem for a survey in Wennington?
Usually it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Wennington is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
What insurance do you have?
Our cover is professional indemnity plus public liability.
How do I arrange electronic leak detection in Wennington?
Simply call 07833 053749 or drop us an email. After a few questions, we confirm the price and fix a day.
What if it rains on the day?
It depends on the weather and the survey. High wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Can you find leaks on a covered flat roof?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We talk this through first.
What this survey cannot tell you
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Moisture spread under the membrane
- Some conductive membranes
- Carrying out the repair work
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer. What our survey covers.
Roof types and parts we check
- Single-ply roofs
- Flat roof membranes
- Commercial flat roofs
- Liquid-applied waterproofing
- Green roofs
- Roof terraces and balconies
What we do, step by step
We check the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. In Wennington, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it’s useful to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Let us know about parking near the property
- Make a note of anything you’d like us to look at
- Let us know about any leaks, stains or damp patches you know of

Tips that help
Most of what helps is simple and safe from the ground. A few suggestions:
- Note where leaks show inside and when
- Do not keep patching the same spot
- Keep outlets clear of debris
- Don’t leave water getting in
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
Signs you need electronic leak detection in Wennington
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Look out for signs like these:
- Leaks through a covered membrane
- New membranes needing a check before handover
- Leaking laps in the waterproofing
- Leaks showing away from the breach
Anyone responsible for a site like Brady Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- How much experience they have with roofs like yours
- Their drone registration, if they fly one
- What follow-up you get after the report
How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- Chimneys, valleys, parapets and other details
- Extensions, dormers and garages with roofs of their own
- The use of thermal imaging or a drone
- The roof’s overall size
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
What to let us know when you get in touch
If you can, have these to hand when you get in touch:
- What’s prompted the survey
- Pictures of the roof from a safe spot, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- Your postcode, so we can check access and travel
Getting a price is simple: just ring 07833 053749 or email us, let us know about the property and we will explain which survey suits. The price is agreed up front.
