Pre-purchase roof survey in Thornhill: what you get
The best time to book is once your offer has been accepted and before you exchange contracts. At that point you can still ask questions, while you are not yet committed. We survey on weekdays and at weekends, which helps when a sale is moving quickly. The report comes within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. Typical surveys look at gutters choked with leaves and moss and worn or lifted lead flashings, on clay and concrete tiles, flat-roofed extensions and dormers and natural slate.
Around Thornhill, you will mostly find houses and bungalows of different ages. Older roofs may still have their original slates or clay tiles, with fixings and underlay that have done a long stint. Whether you’re buying or have just had the roof replaced, that hidden layer is worth knowing about. Older roofs often have bitumen felt under the coverings, as breathable membranes only arrived in the late 1990s.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

Common questions in Thornhill
Is my home in Thornhill listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is the coastal weather around Thornhill hard on roofs?
Frequently, yes. Thornhill is within about 3 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
When will the report arrive?
That depends on which survey you choose: Basic within 48 hours, Standard within 24 to 48 hours and Premium the same day. Let us know your timetable when booking.
Is this the same as a RICS Level 2 or Level 3 survey?
No. We survey the roof, not the whole building, and it’s not a RICS Level 2 or Level 3 survey. It works alongside a home survey.
Can I take the findings back to the seller?
Yes. You’ll have photos and a written description of each defect, which you can share with the seller or agent. We can’t promise how the seller will respond.
Do I need a roof survey if I’m having a RICS survey?
That depends on how much you want to know about the roof. A home survey may recommend further investigation of the roof, and our survey gives you that closer look. It doesn’t stand in for a RICS survey.
How do I book a survey in Thornhill?
To arrange a survey, ring 07833 053749 or use the contact form and tell us the address and what you want to find out. We’ll confirm the price and agree a day with you.
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
Why act early in Thornhill
Small roof defects let water in slowly. 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 an older home around Thornhill, water from a roof defect can get into timber and plaster, and that’s a much bigger job than the original defect.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 with VAT included. We’ll tell you which package suits the questions you have.

What we are asked to look at in Thornhill
The fixings and underlay often fail before good slates or tiles do. Natural slate can last 100 years or more, yet the nails holding it rust and let slates slide. That kind of wear is common on older roofs and easy to miss from ground level.
Problems we come across often include:
- Worn or lifted lead flashings
- Chimney mortar that has eroded
- Quick fixes on flashings and valleys
- Gutters choked with leaves and moss
Take an older house close to St Christopher: the roof’s history matters as much as its looks, and a survey brings the past repairs to light.
Choosing a roof surveyor
- What exactly goes into their report
- Which parts of the roof they’ll actually see
- Whether the loft is part of the inspection
- Do they have a CAA Flyer ID and Operator ID for drone work?
Pre-purchase roof surveys in Thornhill: local notes
Thornhill lies within about 3 miles of the sea, and wind near the sea can be strong. The weather on the day decides whether a flight goes ahead, as a small drone can’t fly safely in strong wind or heavy rain. Thatch survives on some older buildings in Hampshire’s villages. 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.
Historic houses such as South Stoneham House, about 2.4 miles north-west, show how far back building around Thornhill goes. Buying a period property here means asking about the roof’s age and repairs, and about any listing or conservation area. If you own a rental within reach of Sholing station, a written report helps before buying a rental or paying for a new roof on one.

How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes an hour or two at the house you’re buying, depending on its size and how much of the roof can be seen. You are welcome to ask questions while we are there. Being in a smaller place like Thornhill does not change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- After your offer is agreed, you book and share your timetable.
- We arrange access with you, the agent or the seller, including the loft.
- The visit begins outside, from ground level and any safe vantage points.
- Inside, we check the loft space and look at the roof from windows.
- You get a photo-illustrated written report and recommendations before you exchange.
How to prepare
- Check we can get to the back of the property
- Have any questions written down, so nothing gets missed
- Make sure pets are kept safely away
Arrange a survey
A quick phone call is normally the easiest start: ring 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.

How the survey changes by roof type
Natural slate
Many older homes in London and South East England have slate roofs. We look for slates that have slid, cracked or gone, and for clips or tingles that show past repairs.
Flat roofs
Repeated coatings on a flat roof can mask what’s underneath. We say when the covering would need opening up to know more.
Rented homes, blocks and businesses
Landlords, agents and building managers in Thornhill and across Southampton can book any of our surveys. For a price for a let property or a block, call 07833 053749 or drop us an email.
