Electronic leak detection in Over Norton: what you get
ELD can be carried out in more than one way. Low-voltage methods normally need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. If you’ve noticed damp inside with no sign on the roof and a flat roof leak that can’t be traced, a survey will tell you what’s going on.
Flat roofs on exposed homes in small places like Over Norton take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. It records what’s sound as well as what isn’t.

Why get it checked now?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.

Your questions about electronic leak detection in Over Norton
How do I find out if my home in Over Norton is listed?
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.
Will you come out to Over Norton?
Yes, Over Norton is covered. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Will you fly a drone over my roof?
Yes, where it’s applicable. 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.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
How experienced are you?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
What we look for on each type of roof
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.

Common roof problems in Over Norton
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
These are some of the problems a survey can pick up:
- A flat roof leak that can’t be traced
- Leaks through a covered membrane
- Breaches around outlets and penetrations
- Leaks that return after repairs
If you run a hotel or guest house in or near Over Norton, a roof problem can mean rooms out of use, so it pays to find faults before guests do.
Choosing a roof surveyor
- Are they insured for the work?
- Which parts of the roof they’ll actually see
- Whether VAT is in the quoted price
- What the report includes, and whether it has photos
Electronic leak detection in Over Norton: local notes
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 4.1 miles west lies Chastleton House, a reminder of how long the area around Over Norton 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.
Anyone responsible for a site like Holy Trinity Catholic School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you live in an older home near St James, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Over Norton is about 11 miles south-west of Banbury, in Oxfordshire. Whether the building in Over Norton is a house, a flat or a commercial unit, we can survey the roof. Over Norton is one of the towns and villages in Oxfordshire we cover. There is also a page for Oxford.

Should I look at the roof myself first?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
How the survey works
We check the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Somewhere as small as Over Norton, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
