How electronic leak detection works in Norbury
A leak in a flat roof frequently shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We’re often asked to look into leaks showing away from the breach and water coming in under a flat roof, on flat roof membranes, commercial flat roofs and single-ply roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Norbury, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

Norbury: your questions answered
Is Norbury in the area you cover?
Yes, Norbury is within the area we cover. Our area covers London and the South East. Just ring 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.
Is parking a problem for a survey in Norbury?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
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.
How do I arrange electronic leak detection in Norbury?
The quickest way is to phone 07833 053749 or send us an email. Give us the address and a few details about the roof, and we will recommend the right survey. We survey on any day of the week.
Can you inspect my roof with a drone?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Can every flat roof be tested?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. We’ll tell you if yours is not suitable before testing.
Why act early in Norbury
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
The cost of a survey depends on the roof: 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.

What happens on the day
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. In Norbury, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Let us know about parking before the day
- Check we can get to the back of the property
- Have any questions written down, so nothing gets missed
Arrange a survey
Every survey is priced before it is booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, call 07833 053749 or email us.

Electronic leak detection around Norbury
About 1.9 miles north-east lies Kingswood House, a reminder of how long the area around Norbury 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. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
As a London address, Norbury can be tricky for parking: tell us about permits, visitor bays or off-street space as you book, as a space near the door can’t be promised. Shop and office owners around Centrale Croydon may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts. For landlords with property near Norbury station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Useful tips for Norbury property owners
Most of what helps is simple and safe from the ground. Our suggestions:
- Make sure trades protect the waterproofing
- Clear flat roof outlets regularly
- Consider ELD before paving or planting goes on
- Limit access to the roof
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
