Electronic leak detection in Oxhey: what you get
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. We survey green roofs, roof terraces and balconies and flat roof membranes, and the problems we’re asked to look at most are waterproofing to test before it’s covered and leaks through a covered membrane.
In smaller places like Oxhey, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

How it works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photos as we go and record our findings for the written report. Most visits take a length of time set by the membrane area and the build-up, which we set out in the quote. In a smaller place like Oxhey, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- 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.
Getting ready for the survey
- Check we can get to the back of the property
- Agree roof access with the managing agent if it is shared
- If you are buying, check with the agent that we can get in

Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
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.
Roof by roof
Bituminous membranes
ELD is frequently possible on bituminous membranes, depending on what’s below.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
Local flat roofs in Oxhey
Within a mile and a half or so of Oxhey there are several hotels. If you look after one, a leak through a flat roof can put a room out of use. About 3.7 miles south lies Headstone Manor, a reminder of how long the area around Oxhey has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
Take an older house close to Church of St James: flat-roofed rear additions and dormers added over the years are worth checking. If you look after a shop, office or commercial unit, for example near Harlequin Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Oxhey is about 1 mile west of Bushey, in Hertfordshire. From houses to flats and shops in Oxhey, the roof can be surveyed. Oxhey is one of the towns and villages in Hertfordshire where we work for electronic leak detection. There’s also a page for London.

Oxhey questions
Is Oxhey within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is my home in Oxhey listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
Will you go up on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Do you need electronic leak detection in Oxhey?
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Most people get in touch when they’ve noticed something like this:
- Repairs that haven’t stopped the leak
- Leaks under green or ballasted roofs
- Holes left by work on the roof
- A flat roof leak that can’t be traced
Take a building like Bushey Manor Junior School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
What to check before booking
- How much experience they have with roofs like yours
- Whether any drone flown is registered with the CAA
- Will the report include photos?
- Their report turnaround times

Useful tips for Oxhey property owners
You don’t need to be a roofer to help. Here’s what helps most:
- Find the breach before more patching
- Share any drawings of the roof
- Get leaks traced quickly
- Test new membranes before covering them
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Check contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
What affects the price in Oxhey
The price reflects the time and kit the roof needs. That comes down to:
- Extra roofs, like extensions, dormers or garages
- The size of the roof
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs 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.
