Signs you need a pre-purchase roof survey in Blackthorn
Gutter problems often look minor from the street. Overflowing water soaks walls and can rot the timber behind. Hidden gutters behind parapets or in roof valleys can send water indoors. They’re part of what we look at.
Typical things we’re asked to look at include:
- Cracked flaunching or crumbling chimney pointing
- Slates or tiles that have slipped or gone
- Blocked or leaking gutters
- Damp timbers or stains in the loft
If you own a rental within reach of Bicester Village station, a written report helps before buying a rental or paying for a new roof on one.
Choosing a roof surveyor

Pre-purchase roof surveys for homes and businesses in Blackthorn
The roof is one of the most expensive parts of a home to repair, and one of the hardest for a buyer to see. A pre-purchase roof survey looks at it closely before you’re tied in. We look at the slates or tiles, the ridges and valleys, the flashings, the chimneys and the gutters, and the roof space where it’s safe to get in. The findings come in a written report with photos. If you’re worried about roof slopes that look uneven or sagging and ponding, blisters or splits on a flat roof, a survey will tell you what’s going on.
Older buildings in small places like Blackthorn may be listed or in a conservation area. That can affect what materials a new roof may use, so check with the council and Historic England’s list. 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.
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.

Blackthorn homes and their roofs
Boarstall Tower, about 3.3 miles south, is one of the historic houses in the wider area around Blackthorn. Older homes in the wider area frequently have features worth a closer look, like 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. West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new.
Take an older house close to Church of St Mary the Virgin: ask the seller about past roof repairs, because older roofs frequently have patched valleys, replaced slates and reset ridges.
Blackthorn is about 3 miles south-east of Bicester, in Oxfordshire. Blackthorn gets the same service as everywhere else we work: a careful inspection, photographs and a written report.

Getting in touch
Before you get in touch, it helps to have:
- Pictures from the garden or a window, if you have them
- Your postcode, so we can check access and travel
- Why you want a survey: buying, a leak, a storm or new work
- Where water is showing inside, if it is
Most bookings start with a short call: ring 07833 053749 or send us an email, and we will ask about the building and what you need. You’ll have a price before anything is arranged.
Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Ask the seller about past roof repairs
- Notice patches of new decoration in top-floor rooms
- Give your solicitor a copy of the report
- Ask the agent to check the loft hatch can be opened
It is worth sharing the report with your solicitor so they can raise enquiries with the seller’s side. It can prompt questions about past roof work and any paperwork for it.
Once you’ve moved in, keep gutters, valleys and outlets clear, ideally once the leaves have dropped. Blocked gutters cause much of the damp we see. Get a professional in rather than climbing up yourself.
How the survey works
We work from the outside in: outside views come first, then the loft space if there’s safe access. In total, it takes an hour or two at a typical home, and longer for a large or complex roof. For a village or hamlet like Blackthorn, the journey is planned beforehand: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it is safe.
- We help you pick the package that suits the property.
- We agree a visit, including weekends if that helps.
- We inspect and photograph every part of the roof we can safely see.
- Moisture detection, structural checks, thermal imaging or a drone are added where your package includes them.
- You receive the report, with findings prioritised by urgency, so you can raise them with the seller.
Getting ready for the survey
- Find any records of previous roof work
- For flats, check roof access has been agreed
- Keep pets out of the way during the survey

Why get it checked now?
A slow leak can go unnoticed for months. Damp can spread into timbers and ceilings before anyone sees a mark. Spotting it before you buy means you know about it from day one. In a place like Blackthorn, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, including VAT. We can help you choose the package that fits what you’d like to know.
Why book us in Blackthorn
- 5,000+ roofs surveyed
- An independent view of the roof
- Professional indemnity and public liability insurance
- Drone and thermal imaging surveys available

Questions from Blackthorn
Will you come out to Blackthorn?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route when booking.
Do you cover Blackthorn?
Yes. We survey roofs across London and South East England, and Blackthorn is part of that. You can ring 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
How soon is the report ready?
The Premium Survey has a same-day report, Standard 24 to 48 hours and Basic within 48 hours. We send it by email with photos included.
Do you need to go inside the property?
Where we can, yes. Inside, the loft shows leaks, damp timbers and the underlay. If we can’t get in, the report says so.
Does your survey replace a RICS home survey?
No. Our survey looks at the roof only, and it is not a RICS home survey. It complements one rather than replacing it.
Is a roof survey worth having alongside a home survey?
They do different things. A RICS home survey covers the whole building, while ours looks only at the roof, in more detail. Our survey complements a RICS survey and doesn’t replace one.
Honest limits
In fairness, a roof survey has limits:
- A valuation or a promise of a lower price
- The condition of the rest of the house (that is a RICS home survey)
- Asbestos testing of any kind
