Flat roofs in Upper Arncott
Historic houses like Boarstall Tower, about 2 miles south-east, show how far back building in the area around Upper Arncott goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Older buildings in west Oxfordshire frequently have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you run a business near Bicester Village, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Landlords with a home close to Bicester Village station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Electronic leak detection for homes and businesses in Upper Arncott
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. Common reasons to book are new membranes needing a check before handover and damage from equipment installers, on roof terraces and balconies, commercial flat roofs and flat roof membranes.
Flat roofs on exposed homes in small places like Upper Arncott take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically 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 it makes sense without any roofing background. Photos show what each point refers to, with the urgent items made clear.

How the survey changes by roof type
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.

Landlords, agents and block managers in Upper Arncott
We survey roofs for letting agents and landlords as well as householders. A report with photographs gives you a clear record of the flat roof membrane, useful for planning maintenance.
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run seven days a week, which helps when tenants work during the week.
Questions from Upper Arncott
Do you carry out roof surveys in Upper Arncott?
Yes, Upper Arncott is within the area we cover. Our area covers London and South East England. You can call 07833 053749 or drop us an email with the address and a few details, and we will talk through which survey suits.
Do you cover smaller places like Upper Arncott?
Yes, Upper Arncott is covered. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.
Does ELD include fixing the breach?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we will confirm suitability.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
Tips from our surveys
Small things make a difference. Some pointers:
- Ask contractors to protect the membrane
- Get leaks traced quickly
- Consider ELD before paving or planting goes on
- Avoid repeated repairs without finding the cause
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
The survey, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit usually takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In a small place like Upper Arncott, access is normally 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.
