Pre-Purchase Roof Survey in Thorney
A careful look at the roof at your property in Thorney, with photographs and a written report.
- Patch repairs that may hide an ongoing problem
- Signs of past leaks inside the loft
- Chimney mortar that has eroded
How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes roughly 1–2 hours for a house, and more on a big or complicated roof. For a village or hamlet like Thorney, the journey is planned beforehand: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- You get in touch after your offer is agreed, with the address and your target exchange date.
- Access is arranged through you, the agent or the seller.
- We inspect the roof from the ground, windows, the loft and the roof itself where it is safe.
- We check and photograph the slates or tiles, ridges, valleys, flashings, chimneys and gutters.
- We email a photo-illustrated written report and recommendations, ready for you to use before exchange.
Before the survey
- Keep pets in another room
- Have any questions written down, so nothing gets missed
- If it is not your property yet, arrange access through the agent

Pre-purchase roof surveys for homes and businesses in Thorney
The roof is one of the most expensive parts of a home to repair, and one of the hardest for a buyer to see. Our pre-purchase roof survey gives you a close look at it before you’re committed. We look at the slates or tiles, the ridges and valleys, the flashings, the chimneys and the gutters, and the loft space where it’s safe to get in. You get a written report with photos. If you’ve noticed blocked or leaking gutters and standing water on a flat extension roof, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Thorney may be listed or in a conservation area. If so, re-roofing in different materials may need consent, so check with the council before work starts. Whether you are buying or signing off new roofing, it is worth knowing where you stand. There are about 500,000 listed buildings and around 10,000 conservation areas in England.
Where we cannot see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Leave it or get it looked at?
Without a survey, you are relying on a glance from the pavement. That will not show slipped slates on the rear slope, a worn valley or cracked flaunching. We fill that gap before you are tied in. Where a roof is exposed, as many are in small places like Thorney, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Pre-purchase roof survey starts from £150, including VAT.
Why book us in Thorney
- Surveys seven days a week
- Thermal imaging and drone inspection where they help

- Two decades and more of roof surveys
How we price pre-purchase roof surveys
We confirm the price for the job before booking. This is what makes a difference:
- Whether thermal imaging or a drone is needed
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- Extensions, dormers and garages with roofs of their own
To find out what your survey will cost, phone 07833 053749 or use the contact form with the address and a few details. The price is agreed before a date is set.
What to let us know when you get in touch
There’s no need for technical words. Just let us know:
- Access details, such as a loft hatch or a shared roof
- Any stains, drips or damp patches you’ve seen indoors
- Pictures from the garden or a window, if you have them
- The type of building and roof, like pitched or flat
Every survey is priced before it’s booked, so you know the cost up front. Prices start from £150, including VAT. For a price for your roof, phone 07833 053749 or email us.
Thorney: your questions answered
Do you cover smaller places like Thorney?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Is my home in Thorney listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will the roof report help me negotiate with the seller?
Yes. Buyers use the findings to ask questions, ask for repairs before completion or ask for a price change. The outcome is between you and the seller.
Is a roof survey worth having alongside a home survey?
They do different things. A home survey looks at the whole property, and ours concentrates on the roof alone. Our survey complements a RICS survey and doesn’t replace one.
Will you climb onto the roof?
When conditions and the roof make it safe, yes. Many roofs can be seen well from windows, vantage points and the loft, and a drone is part of the Premium Survey where applicable.
How long does a pre-purchase roof survey take?
On site, it typically takes roughly 1–2 hours at a typical house, with time for the loft where it can be reached. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Can you inspect my roof with a drone?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- What’s under the slates, tiles or felt
- Confirmation of asbestos in cement sheets or soffits
- The condition of the rest of the house (that’s a RICS home survey)
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we will tell you before booking. What our survey covers.
What we check
- The roof space
- Clay and concrete tiles
- Chimney stacks
- Natural slate
- Flat-roofed extensions and dormers
- Gutters and downpipes
- Lead flashings and valleys
Pre-purchase roof surveys around Thorney
About 4.6 miles north-east lies Ickenham Hall, a reminder of how long the area around Thorney has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. The flight restriction zone around Heathrow Airport covers Thorney, or comes right up to its edge. If the drone is used for your survey, we ask the airport for permission first, and only fly if it’s given.
If you own one of the older houses in the streets near St. Leonard's, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges.

What you can safely check yourself
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
What we are asked to look at in Thorney
Blocked or leaking gutters do damage that is not obvious at first. Water spilling over a gutter soaks brickwork and can rot fascias and rafter ends. Valley and parapet gutters can overflow inside the house. We check them as part of the survey.
A survey can pick up problems such as:
- Worn or lifted lead flashings
- Ponding, blisters or splits on a flat roof
- Gaps where slates or tiles have come loose
- Gutters that overflow or drip at the joints
For landlords with property near Iver station, the roof is worth checking before you add another property to a portfolio or pay a roofer in full.
