About our electronic leak detection in Osney
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. Typical surveys look at punctures from foot traffic or tools and leaks through a covered membrane, on flat roof membranes, liquid-applied waterproofing and commercial flat roofs.
Outbuildings, garden rooms and garages in places like Osney often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It is worth mentioning them when booking, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

How the survey changes by roof type
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Test new membranes before covering them
- Do not keep patching the same spot
- Get leaks traced quickly
- Ask contractors to protect the membrane
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Flat roofs in Osney
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Within a mile and a half or so of Osney there are several hotels. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Hotels and guest houses near Osney can’t easily close rooms for a leak, so it is worth knowing the roof’s condition. For landlords with property near Oxford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Osney is about 2 miles west of Oxford, in Oxfordshire. Whether the building in Osney is a house, a flat or a commercial unit, we can survey the roof on a weekday or at the weekend. Our Oxfordshire coverage includes Osney and the places around it.

Do you need electronic leak detection in Osney?
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Typical things we’re asked to look at include:
- Leaking laps in the waterproofing
- Breaches around outlets and penetrations
- Repairs that haven’t stopped the leak
- New membranes needing a check before handover
If you look after a building such as West Oxford Community Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

- When you will get the report

What affects the price in Osney
We confirm the price for your survey before you book. These are the things that affect it:
- How big the roof is
- The type of building, from a house to a block or an office
- How many separate roofs there are, such as extensions, dormers and garages
- 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. 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
A little information up front helps. Please include:
- Where water is showing inside, if it is
- The kind of building and roof involved
- The address and postcode of the property
- Anything about access we should know
To arrange a survey, ring 07833 053749 or email us and let us know the address and what’s prompted the survey. You will know the price before anything is booked.
Questions from Osney
Is my home in Osney listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Osney within the area you cover?
Yes, Osney is on our map. Villages and rural addresses get the same survey as a town house.
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.
What if it rains on the day?
Light rain is normally fine; heavy rain and wind are different. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
Can you survey at the weekend?
Surveys run on any day of the week. To find a day that suits you, call 07833 053749 or drop us an email.

How it works
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. Most visits take a length of time set by the roof’s area and construction, which we’ll explain when we quote. For a survey in Osney, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Unlock side gates and any roof access doors
- Agree roof access with the managing agent if it is shared
