North Leigh Electronic Leak Detection
We carry out electronic leak detection in North Leigh and the rest of Oxfordshire. Surveys run on any day of the week.
- New roofs to check before paving or planting
- Punctures from foot traffic or tools
- A flat roof leak that can’t be traced
Electronic leak detection for homes and businesses in North Leigh
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. Typical surveys look at damp inside with no sign on the roof and leaks at pipes, outlets or fixings, across liquid-applied waterproofing, flat roof membranes and green roofs.
In a small place like North Leigh, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

We only report what can safely be seen on the day, so some things are outside what a survey can do:
- Leaks from plumbing or windows
- How wet the insulation is
- Sections we can’t safely access

Roof by roof
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Flat roofs in North Leigh
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around North Leigh has a long history of building, with Blenheim Palace about 3.9 miles north-east. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Landlords with a home close to Combe station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings like North Leigh Church of England (Controlled) School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. The streets around a church such as St Mary's Church are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

The survey, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. You are welcome to ask questions while we’re there. For a village or hamlet like North Leigh, the journey is planned beforehand: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Show us where any leaks or stains appear
- Have any paperwork from past roof work to hand
- For a flat or shared roof, check access with the freeholder or managing agent
How to book
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, ring 07833 053749 or email us.

North Leigh: your questions answered
Is North Leigh in the area you cover?
We do. Every survey there gets the same written report with photos.
Is North Leigh within the area you cover?
Yes, North Leigh is on our map. Villages and rural addresses get the same survey as a town house.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or send us an email.
Can you inspect my roof with a drone?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Send us details of the roof. Just ring 07833 053749 or email us for a quote.
Do I have to be there for the survey?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Checking the roof from ground level
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
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.
What affects the cost of electronic leak detection
We confirm the exact price before booking. This is what makes a difference:
- Whether it’s a home or a commercial building
- How big the roof is
- If the survey needs thermal imaging or a drone
- Chimneys, valleys, parapets and other details
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.
What to let us know when you contact us
Before you get in touch, it’s useful to have:
- The kind of building and roof involved
- Any deadline, like an exchange date
- Any marks or damp showing indoors
- Pictures of the roof from a safe spot, if you have them
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or use the contact form when you’re ready.
Before and after the survey
Here are a few things we’d tell any owner:
- Keep foot traffic on flat roofs to a minimum
- Note where leaks show inside and when
- Don’t leave water getting in
- Find the breach before more patching
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
