About our electronic leak detection in Selhurst
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We will 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. We’ll tell you if the roof can’t be tested. Common reasons to book are new membranes needing a check before handover and leaks through a flat roof with no obvious cause, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Selhurst, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Why act early in Selhurst
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why us?
- Thermal imaging and drone inspection where they help

Roof by roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
What happens on the day
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. A typical survey takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. In Selhurst, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it is useful 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.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Show us where any leaks or stains appear
- Tell us where we can park nearby
- Unlock side gates and any roof access doors

Practical tips
Here are a few things we’d tell any owner:
- Don’t let outlets block
- Do not leave water getting in
- Test new membranes before covering them
- Stay off the flat roof unless needed
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Common questions in Selhurst
Is parking a problem for a survey in Selhurst?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Does a conservation area affect roof work in Selhurst?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
What is electronic leak detection?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That is how we locate breaches you cannot see.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we look at the roof first.
What’s the best way to book?
Just ring 07833 053749 or send us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or drop us an email.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.

What we are asked to look at in Selhurst
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
We are frequently asked to look at:
- Patched roofs that still leak
- New roofs to check before paving or planting
- Holes around roof penetrations
- Leaks under green or ballasted roofs
The streets around a church such as Church of St Mark are often among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof.

Local flat roofs in Selhurst
About 2.2 miles north lies Kingswood House, a reminder of how long the area around Selhurst has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For a London address like Selhurst, it helps to know about controlled parking before the day. For landlords with property near Norwood Junction station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
