Electronic leak detection around Deddington
Historic houses like Broughton Castle, about 5 miles north-west, show how far back building in the area around Deddington goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. There are several hotels within about a mile and a half of Deddington, and hotels, like offices and blocks of flats, frequently have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
Take a building like Deddington Church of England Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. For an older house near a landmark such as Church of St Peter and St Paul, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

How electronic leak detection works in Deddington
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photographs of each breach found. We survey commercial flat roofs, flat roof membranes and single-ply roofs, and common reasons people get in touch are leaks through a covered membrane and leaking laps in the waterproofing.
Somewhere as small as Deddington, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

What we do, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes a length of time set by the membrane area and the build-up, which we set out in the quote. In a small place like Deddington, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent
- Leave side gates unlocked
- Gather any invoices or paperwork from past roof work

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear flat roof outlets regularly
- Find the breach before more patching
- Let us know about the membrane and build-up if you know it
- Use boards when working on the roof
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Do not leave a flat roof leak running. Water under a membrane can spread.
Deddington questions
Do you cover commercial flat roofs around Deddington?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building.
Does a conservation area affect roof work in Deddington?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed as you book.
What do I do with the report?
You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
How many surveys have you done?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs.
What we can’t see
Before you book, it’s worth knowing what a survey will not do:
- Water entering through details rather than the membrane
- Sections we can’t safely access
- Moisture spread under the membrane

Different roofs, different checks
Inverted and paved roofs
We will tell you if your inverted or paved roof is not suitable.
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Can I check my roof myself?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.

Common roof problems in Deddington
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
A survey can pick up problems such as:
- Damp inside with no sign on the roof
- Leaking laps in the waterproofing
- Leaks under green or ballasted roofs
- New membranes needing a check before handover
For landlords with property near Kings Sutton station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- Whether you get a written report with photos
- Which viewpoints they use to see the roof
- What insurance they carry
- Do they have a CAA Flyer ID and Operator ID for drone work?
