Electronic Leak Detection in Aldersbrook

What electronic leak detection does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that is for your roofer)
- The extent of water in the insulation
If in doubt, phone 07833 053749 or drop us an email and we will recommend the right survey before booking. The full list of what we check.

Electronic leak detection in Aldersbrook: what you get
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. Typical surveys look at leaks showing away from the breach and leaks under green or ballasted roofs, across roof terraces and balconies, commercial flat roofs and flat roof membranes.
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 block or conversion in Aldersbrook, the flat roof is frequently a shared part of the building.
Where we can’t see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t.

Do you need electronic leak detection in Aldersbrook?
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Common reasons to book include:
- Leaks under green or ballasted roofs
- A flat roof leak that can’t be traced
- Failed seams and laps
- Holes around roof penetrations
Anyone responsible for a site like Aldersbrook Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- How they plan to inspect the roof safely
- Whether the loft space is looked at, where there is one
- Is there a chance to talk the report through?
- When you will get the report
Different roofs, different checks
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
What we do, step by step
Where it is 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. The whole visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Surveys in Aldersbrook can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive
- Show us where any leaks or stains appear
- If it is not your property yet, arrange access through the agent
- Let us know about parking before the day
Book a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To get started, phone 07833 053749 or use the contact form.
Advice
Aldersbrook questions
Can parking be tricky for a visit in Aldersbrook?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is my home in Aldersbrook listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is Aldersbrook in your area?
Yes. We survey roofs in Aldersbrook and the rest of Greater London. To book, phone 07833 053749 or use the contact form.
Which days do you carry out surveys?
Surveys run on any day of the week. To arrange a date, phone 07833 053749 or email us.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll confirm suitability.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
Can I check my roof myself?
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
