Electronic leak detection for homes and businesses in Woodcote Green
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. We are often asked to look into leaks through a covered membrane and leaking laps in the waterproofing, across commercial flat roofs, single-ply roofs and liquid-applied waterproofing.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Woodcote Green, 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.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Your questions about electronic leak detection in Woodcote Green
Will parking be an issue for a roof survey in Woodcote Green?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Does a conservation area affect roof work in Woodcote Green?
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 I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
What do I do with the report?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
What electronic leak detection does not cover
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Build-ups without a suitable layer below
- How wet the insulation is
- Repairing the breaches (that is for your roofer)
If you’re not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer before you book. The full list of what we check.

Flat and commercial roofs around Woodcote Green
Historic houses like Nonsuch Mansion, about 3.6 miles west, show how far back building in the area around Woodcote Green goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you run a business near St George's Walk, a flat roof over a business is out of sight and out of mind until it leaks. For landlords with property near Reedham (London) station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What we do, step by step
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Woodcote Green runs like any other.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Let us know about parking near the property
- Leave a clear route to the loft
- Have any questions written down, so nothing gets missed

Related advice
Leave it or get it looked at?
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. When the stain finally shows, the damage underneath is frequently older than it looks.
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.
