Electronic leak detection in Cothill: what you get
Our ELD report shows where each breach was found with photos. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you’ve noticed stains far from any visible defect and gaps at membrane joints, we can find out what’s behind it.
Flat roofs on exposed homes in small places like Cothill take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often 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.
After the visit, you get a photo-illustrated written report, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Electronic leak detection around Cothill
Historic houses such as Appleton Manor, about 1.8 miles north-west, show how far back building in the area around Cothill goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. 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.
If you live in an older home near Church of St Helen, flat-roofed rear additions and dormers added over the years are worth checking. Take a building like Dry Sandford Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Radley station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What else we do in Cothill
Surveys for landlords and agents in Cothill
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
We survey roofs for landlords and agents as well as householders. A report with photographs gives you a clear record of the flat roof membrane, useful for planning maintenance.
What a survey costs
Prices always include VAT. The things that change the price are:
- Any need for thermal images or a drone flight
- House, block, shop or office
- How big the roof is
- The height of the building and how the roof can be seen safely
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
If you can, have these to hand when you contact us:
- What kind of property and roof it is
- The address and postcode of the property
- Anything about access we should know
- Pictures from the garden or a window, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or use the contact form with the address and the days you’d prefer.
How it works
Safety comes first on every visit. We inspect everything that’s safely in view, and anything we cannot see is noted in the report. The survey typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Cothill can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- For flats, make sure roof access has been agreed
- Make sure the loft hatch can be reached
Getting a price
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or email us when you are ready.

Honest limits
Some things cannot be seen without opening up the roof, so a survey has limits:
- Areas we cannot reach or that can’t be tested
- Build-ups without a suitable layer below
- The extent of water in the insulation
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we’ll tell you. What a survey covers and doesn’t.
What this survey covers
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Roof terraces and balconies
Before and after the survey
Over many surveys, some simple habits stand out:
- Act on new leaks promptly
- Tell us about the membrane and build-up if you know it
- Limit access to the roof
- Find the breach before more patching
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
Common questions in Cothill
Do you cover Cothill?
Yes. We cover the whole of London and South East England, and Cothill is part of that. You can call 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
How do I find out if my home in Cothill is listed?
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, and councils can also use Article 4 directions.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Tell us what you know about the roof and we will check whether ELD will work.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know when you book.
What if it rains on the day?
It depends on the weather and the survey. Strong wind or a downpour can make access unsafe and ground a drone, so we’d move the date with you.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We will explain why when we quote.
