Oxford Electronic Leak Detection
Electronic leak detection across Oxford, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.
- New membranes needing a check before handover
- Damp inside with no sign on the roof
- Repairs that haven’t stopped the leak
About our electronic leak detection in Oxford
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you before any testing starts. We’re often asked to look into leaks that return after repairs and leaks through a covered membrane, across roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs.
Commercial units and business premises in places the size of Oxford often have large flat or low-pitched roofs. On a large roof, a leak can be hard to trace by eye. Where the build-up allows, electronic leak detection can help pinpoint holes in the membrane. Membranes typically fail at outlets, upstands and laps, so those get a careful look.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

How the survey works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. Jobs in Oxford might be a terraced house one day and a block of flats the next. Let us know which it is and who controls access, so the right access is in place on the day.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Getting ready for the survey
- Mention any parking restrictions on your street
- If you’re buying, let the agent know when we’re coming
- Make sure we can get to the back of the property
Arrange a survey
Getting a price is simple: just call 07833 053749 or send us an email, tell us about the property and we’ll recommend the right survey. The price is agreed up front.

What else we do in Oxford
Common roof problems in Oxford
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
A survey can pick up problems like:
- Holes left by work on the roof
- Stains far from any visible defect
- Repairs that haven’t stopped the leak
- Leaking laps in the waterproofing
If your house is among the older ones in the streets near St Clement's Church, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before you book
- What insurance they carry
- Is VAT included in the price?
- What’s outside the scope of the survey
- How long the report takes to arrive
Checking the roof from ground level
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
Landlord and commercial surveys in Oxford
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on any day of the week, which can make access easier.
How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
- How big the roof is
- Building height and the viewpoints available
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
Before you get in touch, it’s useful to have:
- Pictures from the garden or a window, if you have them
- The kind of building and roof involved
- What’s prompted the survey
- The property’s address and postcode
If you’re buying, it’s useful 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 ring 07833 053749 or drop us an email when you’re ready.
FAQs for Oxford
Does a conservation area affect roof work in Oxford?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you look at commercial flat roofs near Oxford, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
What happens next?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you use drones?
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.
What does electronic leak detection do?
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.
Flat roofs in Oxford
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their 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. Within a mile and a half or so of Oxford there are several hotels. If you look after one, a leak through a flat roof can put a room out of use.
For hotels and guest houses around Oxford, a roof problem found early is far less disruptive than one found by a guest. If you look after a building like East Oxford Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
