Electronic leak detection in Ascott Earl
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You will also know what to check next. Common reasons to book are new roofs to check before paving or planting and leaks at pipes, outlets or fixings, on flat roof membranes, green roofs and roof terraces and balconies.
In a village or hamlet like Ascott Earl, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

Common roof problems in Ascott Earl
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Things that often lead to a survey include:
- Stains far from any visible defect
- Holes around roof penetrations
- Failed seams and laps
- Punctures from foot traffic or tools
If yours is one of the older homes in the streets near Church of the Holy Trinity, the flat roofs on later extensions tend to wear out long before the main roof.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included
- Which viewpoints they use to see the roof
- What’s outside the scope of the survey

The survey, step by step
Once we have finished looking, we write up our findings in a report with photographs, sent to you by email. On timing, it normally takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. Somewhere as small as Ascott Earl, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Leave side gates unlocked
- Let us know about any leaks, stains or damp patches you know of

Advice
Leave it or get it looked at?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Older and listed buildings around Ascott Earl may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.

Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Share any drawings of the roof
- Don’t let outlets block
- Record dates and spots where water appears
- Find the breach before more patching
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Act on leaks quickly. Water under a membrane can spread.
Electronic leak detection in Ascott Earl: local notes
Older buildings in west Oxfordshire frequently have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Ascott Earl has a long history of building, with Minster Lovell Hall about 4.7 miles south. On older houses around here, roofs often 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.
Landlords with a home close to Ascott-Under-Wychwood station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

Ascott Earl: your questions answered
Do you cover smaller places like Ascott Earl?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How do I find out if my home in Ascott Earl is listed?
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.
How long will testing take?
It typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
How experienced are you?
Over 20 years and more than 5,000 surveys.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
How does ELD work?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Features like valleys, chimneys, dormers and parapets
- How tall the building is and how easy the roof is to see
- Whether thermal imaging or a drone is needed
- How big the roof is
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to let us know when you get in touch
The more you let us know, the easier it is to price the survey. When you get in touch, it’s useful to mention:
- Dates you are working to, like exchange
- The type of building and roof, like pitched or flat
- How the loft is reached, if there is one
- Pictures of the roof from a safe spot, if you have them
To book a survey, phone 07833 053749 or use the contact form with the address and what you’d like to know about the roof. You will know the price before anything is booked.
What electronic leak detection doesn’t cover
Every survey has limits, and it is better to know them up front. Keep these in mind:
- Leaks from plumbing or windows
- Roofs whose membrane or build-up isn’t suitable
- Sections we can’t safely access
