Electronic leak detection in Pinner Green
Our ELD report shows where each breach was found with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs aren’t part of the report, 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. You get a photo-illustrated written report. If you’re worried about damp inside with no sign on the roof and leaks through a flat roof with no obvious cause, we can find out what’s behind it, whatever the roof.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Pinner Green, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

Leave it or get it looked at?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. In Pinner Green, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
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.
Why us?
- Independent findings on the roof’s condition
- Two decades and more of roof surveys

How the survey changes by roof type
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We will say if the test will not work.
For landlords and managing agents
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
If you own several properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or email us with the addresses.
Common questions in Pinner Green
How do I find out if my home in Pinner Green is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Pinner Green?
Yes. We survey roofs across London and the South East, and Pinner Green is part of that. Just phone 07833 053749 or use the contact form and tell us about the property, and we will talk through which survey suits.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we’ll confirm suitability.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Does the report include photographs?
Yes. Photos are part of every report, so you can see each point for yourself.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We will explain why when we quote.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Just say which days work for you.
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
The survey, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. In Pinner Green, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when booking.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- 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.
Getting ready for the survey
- Check the loft hatch can be reached
- For a flat or shared roof, check access with the freeholder or managing agent
- Let us know about parking before the day
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or send us an email when you are ready.

Flat and commercial roofs around Pinner Green
About 1.7 miles east lies Headstone Manor, a reminder of how long the area around Pinner Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you look after a shop, office or commercial unit, for instance near St. George's Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks. For site and facilities teams at buildings like Harlyn Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Hatch End station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
