Flat roof survey in Preston Crowmarsh
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’ve noticed failed seals around rooflight kerbs and ponding water that doesn’t drain away, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like Preston Crowmarsh take more wind and rain, 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.
What you get is a clear record of the flat roof on the day we saw it. It’s useful right away, and a good reference for later, like when you want to compare after future work.

Why get it checked now?
A small split in a flat roof is normally a modest job when it is found early. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Where a roof is exposed, as many are in small places like Preston Crowmarsh, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Signs you need a flat roof survey in Preston Crowmarsh
The surface of a flat roof heats up and cools down far more than the rooms below. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
These are some of the problems a survey can pick up:
- Raised blisters across the surface
- Standing water left after rain
- Splits, cracks and crazing
- Loose or cracked edge trims
For an older house near a landmark like Church of St Helen, the joins between later flat roofs and the old walls are where problems usually start.
Questions to ask before you book
- Whether the price includes VAT
- What insurance they carry
- How long they’ve been surveying roofs
- When you will get the report
What happens on the day
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely, from ground level, from windows, in the loft space and by drone where applicable. The survey usually takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In a small place like Preston Crowmarsh, access is usually 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.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Preparing for the visit
- Move anything stored under the loft hatch
- Leave side gates unlocked
- Show us where any leaks or stains appear
Book a survey
If you have photos of the roof, send them over. Take them safely from the ground or a window, and please do not climb up for a closer look. To get started, phone 07833 053749 or drop us an email.
Advice
Flat roofs in Preston Crowmarsh
Historic houses such as Brightwell Manor, about 2.4 miles west, show how far back building in the area around Preston Crowmarsh goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have 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 you let a flat or house near Cholsey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For hotels and guest houses around Preston Crowmarsh, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
What this survey cannot tell you
Every survey has limits, and it is better to know them up front. Bear these in mind:
- Fragile surfaces, which we do not walk on
- An exact number of years the roof has left
- Asbestos testing, which needs a specialist asbestos surveyor

Preston Crowmarsh questions
Will you come out to Preston Crowmarsh?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Does a conservation area affect roof work in Preston Crowmarsh?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning. Mention it when you contact us and we will plan the survey around it.
Will I get photos?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How do you inspect a flat roof?
It depends on what’s safe: the roof itself where that is safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
Can you tell me how long my flat roof will last?
We do not give a fixed number of years, because so much depends on upkeep, exposure and workmanship. We describe the condition and say which work is urgent and which can wait.
