How a flat roof survey works in Thorney
Offices, shops, industrial units and blocks of flats often sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. We record the condition with photographs so work can be planned and budgeted. We quote commercial roofs on their size and how they’re reached, so it helps if you call 07833 053749 or use the contact form with the address and a rough idea of the roof area. If you’ve noticed water getting in at rooflights and raised blisters across the surface, we can find out what’s behind it, on upstands and outlets, single-ply membranes and EPDM rubber alike.
Older buildings in small places like Thorney may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Keep records of when the roof was laid and what work has been done
- Watch the ceilings below the flat roof for stains
- Check from a window for ponding after heavy rain
- Limit foot traffic on the covering
Once we’ve been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.

FAQs for Thorney
Will you come out to Thorney?
Yes. Thorney is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is my home in Thorney listed or in a conservation area?
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.
How much is a survey?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
How do I book a survey in Thorney?
It’s easiest to phone 07833 053749 or use the contact form. Let us know the address and a little about the roof, and we’ll take it from there. We survey on weekdays and at weekends.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Is a flat roof survey the same as a building survey?
No. It is a closer look at the flat roof, not a survey of the whole property. It works alongside a RICS home survey, not instead of one, and it is not a structural engineer’s report.
What will the report tell me?
A written report with photos, explaining the condition of the flat roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Do you need a flat roof survey in Thorney?
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, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.
Common reasons to book include:
- Pools of water lying on the roof
- Blisters and bubbles in the covering
- Outlets that hold water back
- Splits, cracks and crazing
If you live in an older home near St. Leonard's, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Choosing a roof surveyor

What a flat roof survey looks like in Thorney
Thatch survives on some older buildings in Buckinghamshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Ickenham Hall, about 4.6 miles north-east, show how far back building in the area around Thorney goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For businesses in and around places such as The Pavilions, a flat roof over a business is out of sight and out of mind until it leaks. For site and facilities teams at buildings such as St Catherine Catholic Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. It normally takes an hour or two for most houses, and more on a big or complicated roof. In a small place like Thorney, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Before we arrive
- Check we can get to the back of the property
- Note where any stains or damp appear
- Tell us where we can park nearby

Different roofs, different checks
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. We check the welded laps, the edges, the fixings and any punctures.
GRP fibreglass
GRP roofs can last up to about 30 years when they’re laid well. Hairline cracks over board joints are an early warning we look out for.
What happens if roof problems are left?
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. After that, the cost of any work is yours. Our report gives you specific points to raise with the seller or agent. Around Thorney, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £150, including VAT.
