Electronic leak detection for homes and businesses in South Oxhey
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We will say if ELD won’t work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It saves a wasted visit. We survey flat roof membranes, roof terraces and balconies and single-ply roofs, and people most often book us about waterproofing to test before it’s covered and failed seams and laps.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In South Oxhey, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later, for example when you want to check whether anything has changed.

How we price electronic leak detection
Prices vary from roof to roof, for these reasons:
- The shape of the roof and its details
- The roof’s overall size
- Extensions, dormers and garages with roofs of their own
- House, block, shop or office
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
What we need to know
Getting the details right at the start saves time. Please include:
- The property’s address and postcode
- Any deadline, such as an exchange date
- Why you want a survey: buying, a leak, a storm or new work
- The style of property, from a terrace to a block
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.

Useful tips for South Oxhey property owners
You do not need to be a roofer to help. What helps most:
- Keep outlets clear of debris
- Keep foot traffic on flat roofs to a minimum
- Don’t keep patching the same spot
- Get leaks traced quickly
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Can I check my roof myself?
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
What happens on the day
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. It normally takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In South Oxhey, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- 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.
How to prepare
- Let us know about parking before the day
- Make sure pets are kept safely away
- Move anything stored under the loft hatch
How to book
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please do not climb up for a closer look. To send them or to book, call 07833 053749 or send us an email.

What we look for on each type of roof

Your questions about electronic leak detection in South Oxhey
Is South Oxhey in the area you cover?
Yes. We survey roofs across London and South East England, and South Oxhey is part of that. Just call 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
Can parking be tricky for a visit in South Oxhey?
It depends on the street. If South Oxhey has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Do I need to be at home?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or send us an email.
Does the weather affect the survey?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather is not right.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we’ll explain what’s needed.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
What electronic leak detection looks like in South Oxhey
With Headstone Manor about 2.4 miles south-east, South Oxhey sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in South Oxhey is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Controlled parking zones are common in London, so mention any permit rules for South Oxhey, along with any off-street space. If your house is among the older ones in the streets near Oxhey Chapel, the joins between later flat roofs and the old walls are where problems typically start. Take a building like Greenfields Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
