Northmoor: your questions answered
Is Northmoor within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you carry out roof surveys in Northmoor?
We do. Every survey there gets the same written report with photographs.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We’ll discuss it before we quote.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Are you insured?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
How long will testing take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
How electronic leak detection works in Northmoor
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Let us know about your roof to find out more. We survey liquid-applied waterproofing, flat roof membranes and roof terraces and balconies, and the problems we’re asked to look at most are new roofs to check before paving or planting and leaking laps in the waterproofing.
Somewhere as small as Northmoor, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Useful tips for Northmoor property owners
There is plenty you can do without going near the roof. What helps most:
- Avoid repeated repairs without finding the cause
- Get leaks traced quickly
- Tell us about the membrane and build-up if you know it
- Keep outlets clear of debris
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.

Electronic leak detection around Northmoor
Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Appleton Manor about 1.7 miles south-east, Northmoor sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Northmoor is about 6 miles north-west of Abingdon-on-Thames, in Oxfordshire. If you’re in Northmoor, booking works exactly as it does anywhere else: a call or an email, a price, then a date.

Prices for electronic leak detection in Northmoor
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- Features like valleys, chimneys, dormers and parapets
- How many separate roofs there are, such as extensions, dormers and garages
- How big the roof is
- How tall the building is and how easy the roof is to see
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What we need to know
If you can, have these to hand when you contact us:
- Whether there’s a loft hatch, a shared roof or tricky access
- The style of property, from a terrace to a block
- Your timetable, such as an exchange date
- Where any leaks, stains or damp patches show inside
Photos help, if you have them. Pictures from ground level or a window are fine. To get started, call 07833 053749 or send us an email.
The survey, step by step
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take as long as needed for the roof’s area and construction, which we set out in the quote. In a small place like Northmoor, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Find any records of previous roof work
- Buyers: confirm access with the estate agent or seller
- Show us where any leaks or stains appear

When to book a survey in Northmoor
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in which makes it hard to find by looking.
These are some of the problems a survey can pick up:
- Holes left by work on the roof
- Leaking laps in the waterproofing
- Stains far from any visible defect
- Leaks at pipes, outlets or fixings
Take an older house close to Church of St Denys: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
What to check before booking
- What the report includes, and whether it has photos
- What the survey won’t cover
- Which parts of the roof they’ll actually see
- Whether they hold professional indemnity and public liability insurance
Leave it or get it looked at?
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. Around Northmoor, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
To find out what your survey will cost, phone 07833 053749 or use the contact form with the address and a few details. We will confirm the figure before booking.
