Sandford-on-Thames Flat Roof Survey

- Splits, cracks and crazing
- Failed upstands where the roof meets a wall
How a flat roof survey works in Sandford-on-Thames
Ponding is often the first sign that something on a flat roof isn’t right. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey GRP fibreglass, EPDM rubber and upstands and outlets, and the problems we are asked to look at most are standing water left after rain and splits and cracks in the covering.
Somewhere as small as Sandford-on-Thames, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Flat roof surveys around Sandford-on-Thames
Within a mile and a half or so of Sandford-on-Thames there are several hotels. If you look after one, a leak through a flat roof can put a room out of use. With Garsington Manor about 2.9 miles east, Sandford-on-Thames sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Radley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For hotels and guest houses around Sandford-on-Thames, a roof problem found early is far less disruptive than one found by a guest, so it’s worth knowing the roof’s condition.

How the survey changes by roof type
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We check for splits, gaps and loose flashings above the upstand.
Mastic asphalt
Asphalt has no laps, so its weak points are cracks and the skirtings at walls and upstands. Our report notes crazing, cracks and any likely entry points.
What a flat roof survey doesn’t cover
A survey is a careful look at the flat roof, but it cannot do everything. Its limits include:
- A structural engineer’s assessment of the deck
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A promise that the roof won’t leak in future

When to book a survey in Sandford-on-Thames
People go onto flat roofs for all sorts of reasons: cleaning windows, fitting aerials or air conditioning, or clearing gutters. A covering that wasn’t designed for foot traffic can crack or puncture. Fixings added through the covering frequently start leaks too.
We’re often asked to look at:
- Upstands pulling away from walls
- Blisters and bubbles in the covering
- A sagging deck under the covering
- Outlets that hold water back
If you live in an older home near Church of St Andrew, the flat roofs on later extensions tend to wear out long before the main roof.

Tips that help
Nothing here needs a ladder. A few suggestions:
- Keep people off the roof unless they need to be there
- Ask whoever fits equipment on the roof to make good the covering
- Check ceilings under the roof for damp patches
- Clear roof outlets and gutters each autumn
Landlords, owners and managing agents can keep the report as a dated record of the roof. It is useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
Keep outlets, gutters and hoppers clear, particularly after the leaves fall. A flat roof that drains well wears much more slowly.
Sandford-on-Thames: your questions answered
Do you look at commercial flat roofs near Sandford-on-Thames, like hotels?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Will you come out to Sandford-on-Thames?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
What do I do with the report?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Is this an asbestos survey?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
What if it rains on the day?
It depends on the weather and the survey. In strong wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely, from the ground, from windows, in the roof space and by drone where applicable. Most surveys take roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Rural addresses near Sandford-on-Thames can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Preparing for the visit

- Leave side gates unlocked
- Have any paperwork from past roof work to hand
