How electronic leak detection works in Great Tew
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We will say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. If you’re worried about leaks that return after repairs and leaks at pipes, outlets or fixings, a survey will tell you what’s going on, on flat roof membranes, liquid-applied waterproofing and green roofs alike.
In a small place like Great Tew, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, with the urgent items made clear.

Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Share any drawings of the roof
- Do not leave water getting in
- Keep outlets clear of debris
- Consider ELD before paving or planting goes on
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.

What electronic leak detection looks like in Great Tew
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your home is one of the older ones in the streets near Church of St Michael and All Angels, the joins between later flat roofs and the old walls are where problems usually start.

When to book a survey in Great Tew
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
People usually book a survey after spotting one of these:
- Leaks through a flat roof with no obvious cause
- Stains far from any visible defect
- Holes left by work on the roof
- Leaks that return after repairs
Take a building like Great Tew County Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Before booking anyone

- How long they’ve been surveying roofs
- Their insurance cover
Checking the roof from the ground
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. For an older or listed building in a place like Great Tew, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
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.

Great Tew: your questions answered
How do I find out if my home in Great Tew is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is Great Tew in the area you cover?
Yes. We survey roofs across London and South East England, and Great Tew is part of that. Just ring 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks, and call 07833 053749 or send us an email for a quote.
Does the report include photographs?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
Can you find leaks on a covered flat roof?
Sometimes. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.
Will you repair the leak?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.

Single-ply membranes
Single-ply can be punctured by tools or fixings. Testing helps find them.
Bituminous membranes
ELD is often possible on bituminous membranes though the layers below matter.
The survey, step by step
Once we’ve finished looking, we write up our findings in a report with photos, sent to you by email. As for time on site, it normally takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. For a village or hamlet like Great Tew, the journey is planned ahead of time: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Preparing for the visit
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at
- If it isn’t your property yet, arrange access through the agent
