Electronic leak detection in Woodcote: what you get
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We will say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It saves a wasted visit. If you’re worried about new membranes needing a check before handover and patched roofs that still leak, we can find out what’s behind it, on single-ply roofs, flat roof membranes and commercial flat roofs alike.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Woodcote shapes how it is checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

What we’re asked to look at in Woodcote
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
A survey makes sense if you’ve noticed:
- Waterproofing to test before it is covered
- Holes around roof penetrations
- Stains far from any visible defect
- Leaks through a covered membrane
If you look after a shop, office or commercial unit, for instance near St George's Walk, a flat roof over a business is out of sight and out of mind until it leaks.

Your questions about electronic leak detection in Woodcote
Is parking a problem for a survey in Woodcote?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Is my home in Woodcote listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and call 07833 053749 or use the contact form for a quote.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you get in touch and we’ll explain what’s needed.
Do you cover Woodcote?
Yes. Our area covers London and South East England, Woodcote included.
Flat and commercial roofs around Woodcote
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. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Nonsuch Mansion about 4.3 miles north-west, Woodcote sits in an area with a long building history. 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.
The streets around a church like St Swithun's are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking. Anyone responsible for a site like Woodcote High School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
- Keep foot traffic on flat roofs to a minimum
- Consider ELD before paving or planting goes on
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
What happens on the day
Every roof is different, but as a rough guide the survey takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. If you have questions on the day, just ask. 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 runs like any other.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Tell us where we can park nearby
- Have keys ready for side gates, garages or roof access doors
- Jot down any questions you want answered
