Electronic leak detection to pinpoint holes in flat roof membranes in Denchworth, with drones and thermal imaging where they help. Get in touch for a price.
- Leaks through a flat roof with no obvious cause
- Leaks at pipes, outlets or fixings
- Leaks through a covered membrane
Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Find the breach before more patching
- Check new waterproofing before handover
- Use boards when working on the roof
- Keep outlets clear of debris
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Electronic leak detection in Denchworth: what you get
We carry out electronic leak detection on flat roofs in Denchworth and across London and South East England. A visit usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey commercial flat roofs, liquid-applied waterproofing and roof terraces and balconies, and common reasons people get in touch are repairs that haven’t stopped the leak and new membranes needing a check before handover.
Somewhere as small as Denchworth, flat roofs tend to be on extensions, garages and converted outbuildings. 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.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Flat roofs in Denchworth
West Oxfordshire’s older buildings frequently 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Denchworth has a long history of building, with Longworth House about 4.7 miles north. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.

Your questions about electronic leak detection in Denchworth
Do you cover Denchworth?
Yes. We survey roofs across London and South East England, and Denchworth is part of that. You can phone 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
Is my home in Denchworth 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.
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 every flight depends on the airspace and the weather.
Will you go up on the roof?
Only if it is safe. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
What we are asked to look at in Denchworth
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Typical things we’re asked to look at include:
- Leaks through a covered membrane
- Leaks that return after repairs
- Waterproofing to test before it’s covered
- Leaks through a flat roof with no obvious cause
Take an older house close to Church of St James: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before booking any roof surveyor
- What follow-up you get after the report
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- How long they’ve been surveying roofs
- Their insurance cover
What happens on the day
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. Around Denchworth, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- 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.
Before the survey
- Dig out any old roof reports or invoices
- Mention any parking restrictions on your street
- If the roof is shared, arrange access with whoever manages the building
How to book
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or email us.

What we can’t see
A survey is a proper look at the flat roof membrane, but it can’t do everything. Its limits include:
- Areas we cannot reach or that cannot be tested
- Repairing the breaches (that is for your roofer)
- How wet the insulation is
If in doubt, call 07833 053749 or send us an email and we’ll recommend the right survey before booking. What our survey covers.
Roof types and parts we check
- Flat roof membranes
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
- Single-ply roofs
- Liquid-applied waterproofing
Why it is worth a survey now in Denchworth
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye where the roof suits it. Where a roof is exposed, as many are in small places like Denchworth, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
To find out what your survey will cost, call 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.
