Flat and commercial roofs around Long Wittenham
About 1.2 miles north lies Clifton Hampden Manor, a reminder of how long the area around Long Wittenham has been built on. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. 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.
For landlords with property near Appleford station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a building like Long Wittenham (Church of England) Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Long Wittenham
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing isn’t possible, we will say so. We survey commercial flat roofs, flat roof membranes and green roofs, and common reasons people get in touch are holes left by work on the roof and holes around roof penetrations.
Flat roofs on exposed homes in small places like Long Wittenham take more wind and rain, so edges, upstands and laps take a beating. 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. Exposed edges are typically the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what isn’t.

What you can safely check yourself
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
How we price electronic leak detection
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- How complicated the roof is, with its valleys, chimneys and parapets
- Extra roofs, like extensions, dormers or garages
For a price for your roof in Long Wittenham, ring 07833 053749 or email us and let us know about the roof. We’ll confirm the figure before booking.
What to tell us when you contact us
Before you get in touch, it helps to have:
- How the loft is reached, if there is one
- When you need the report by
- The type of building and roof, like pitched or flat
- Your postcode, so we can check access and travel
Photos help, if you have them. Take them safely from ground level or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or send us an email.
Why get it checked now?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. For older village homes like those around Long Wittenham, the right replacement materials are not always easy to find quickly. That is one more reason to find defects before they become urgent.
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. Electronic leak detection is quoted for your roof, because the method depends on the roof.

When to book a survey in Long Wittenham
Joints and laps in a membrane can fail over time. Small openings at laps can leak long before anyone notices.
Look out for signs like these:
- Repairs that haven’t stopped the leak
- New membranes needing a check before handover
- Breaches hidden under paving or planting
- Leaks at pipes, outlets or fixings
If yours is one of the older homes in the streets near Church of St Mary, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Advice
Tips from our surveys
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Ask contractors to protect the membrane
- Keep a note of leaks after rain
- Tell us about the membrane and build-up if you know it
- Don’t leave water getting in
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
