Pre-purchase roof surveys for homes and businesses in Osterley
We survey roofs for buyers in Osterley and across London and South East England. Whether it is a terrace, a semi, a detached house or a flat, we follow the same careful process. We tell you what’s sound, what needs attention and how urgent it is. We hold professional indemnity and public liability insurance, and have 20+ years’ experience. To book, call 07833 053749 or use the contact form. We’re often asked to look into old water stains in the roof space and loose pots and cracked flaunching, on flat-roofed extensions and dormers, the roof space and clay and concrete tiles.
Many London homes have been converted into flats, extended at the back or given a loft conversion with a dormer. Every alteration brings new junctions, flashings and flat-roof areas to look at. If you are buying a flat or house in Osterley, or have just had new roofing work done, those junctions are frequently where problems start. Dormer cheeks, lead work and new flat roofs are worth checking closely, as faults there are easy to miss.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

Your questions about pre-purchase roof surveys in Osterley
Can parking be tricky for a visit in Osterley?
Normally it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Are there drone restrictions around Osterley?
Typically it comes down to two things: the airspace at the address and the weather. The flight restriction zone around Heathrow Airport comes within about 1 mile of Osterley. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. High wind or heavy rain also stops a small drone flying.
Do you need access inside the house?
If it can be arranged, yes. From the loft space we can see staining, timbers and underlay. If access is not possible, we note it in the report.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
When is the best time to have the roof checked when buying?
Book as soon as your offer is agreed. The report is most useful before exchange, while you can still ask questions and negotiate.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.

Do you need a pre-purchase roof survey in Osterley?
Many roofs have had quick fixes over the years. Bitumen over flashings, mortar fillets in place of lead and odd replacement tiles can point to a problem that keeps coming back. Our report records them so you can ask the seller what was done and when.
Typical things we are asked to look at include:
- Old water stains in the loft space
- Cracked flaunching or crumbling chimney pointing
- Sagging ridge lines or uneven roof slopes
- Slipped or missing slates and tiles
The streets around a church such as St Mary's Church are frequently among the oldest in a place, and if you own one of the older houses nearby, the roof’s history matters as much as its looks, and a survey brings the past repairs to light.
Before booking anyone
- Which limits apply to the survey
- Whether any drone flown is registered with the CAA
- What the report includes, and whether it has photos
- How much experience they have with roofs like yours
What affects the cost of pre-purchase roof surveys
Prices always include VAT. The things that change the price are:
- The roof’s overall size
- Commercial roofs and larger buildings
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
Prices quoted always include VAT, and the written report is part of the package. Our price is from £150, including VAT. Size, height and access decide where your roof falls.
What to let us know when you contact us
When you call or email, these details help:
- Access details, such as a loft hatch or a shared roof
- Where any leaks, stains or damp patches show inside
- Photos of the roof, taken safely from ground level or a window
- When you need the report by
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or send us an email when you are ready.
Rented homes, blocks and businesses
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Pre-purchase roof surveys around Osterley
The flight restriction zone around Heathrow Airport comes within about 1 mile of Osterley. Where the drone is part of the survey, the exact boundary is checked for the address first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new.
Controlled parking zones are common in London, so mention any permit rules for Osterley. Landlords with a home close to Isleworth station may find that the roof is worth checking before you add another property to a portfolio or pay a roofer in full.

Why it is worth a survey now in Osterley
Lots of buyers go ahead anyway, but with their eyes open. The report shows what needs doing first, so you can plan work before small faults get bigger. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

The survey, step by step
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit usually takes roughly 1–2 hours at a typical house, with time for the loft where it can be reached. Surveys in Osterley can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- After your offer is agreed, you book and share your timetable.
- We arrange access with you, the agent or the seller, including the loft.
- We start outside, looking at the roof from the ground and from vantage points.
- We then look from upstairs windows and inside the loft where it is safe.
- You get a written report with photos and recommendations before you exchange.
How to prepare
- Move anything stored under the loft hatch
- Agree roof access with the managing agent if it’s shared
- Mention any parking restrictions on your street
