How a pre-purchase roof survey works in South Harrow
Buyers in South Harrow and right across London and the South East use our pre-purchase roof survey. From terraced and semi-detached homes to detached houses and flats, the roof gets the same careful look. We tell you what’s sound, what needs attention and how urgent it is. We’re insured for professional indemnity and public liability, with more than 20 years’ experience behind us. To arrange a survey, call 07833 053749 or drop us an email. We’re frequently asked to look into lead that has worked loose at a wall or chimney and blocked or leaking gutters, across flat-roofed extensions and dormers, clay and concrete tiles and lead flashings and valleys.
London’s housing runs from Victorian and Edwardian terraces to interwar semis, post-war estates and new blocks of flats, and a home in South Harrow could be any of them. Whether the roof is old or newly laid, the problem areas depend on how and when the building went up. Slates, hidden valley gutters, parapets and flat roofs over back additions all need checking in their own way.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Why get it checked now?
A seller may honestly not know the state of the roof. Their answers on the property forms only cover what they know about. Our survey shows you the roof as it is today. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
What you get with us
- Two decades and more of roof surveys
- A report with photos
- Thermal imaging and drones used where they help
- An independent view of the roof

Pre-purchase roof surveys around South Harrow
RAF Northolt is about 3 miles from South Harrow. If your survey includes the drone, the Drone Safety Map is checked for restrictions first. Northolt Manor, about 1.5 miles south-west, is one of the historic houses in the wider area around South Harrow. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If yours is one of the older homes in the streets near Parish Church of St Paul, older patch repairs can hide behind a tidy front slope, and the survey looks past them. Controlled parking zones are common in London, so mention any permit rules for South Harrow, along with any off-street space.

Common questions in South Harrow
Will parking be an issue for a roof survey in South Harrow?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Are there drone restrictions around South Harrow?
That depends on where the roof is and on the weather. RAF Northolt is about 3 miles away, so we check the Drone Safety Map for restrictions before any flight. 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. Each address is checked against all of them before the drone goes up. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Is your roof survey a RICS survey?
No. It is a dedicated roof survey, with a written report and photographs. It is not a RICS survey and does not cover the rest of the house.
When will the report arrive?
It depends on the package: within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. Let us know your exchange date and we will help you choose.
At what stage of buying should I get the roof surveyed?
The sooner after your offer is accepted, the better. The report is most useful before exchange, because after that the roof is yours to deal with.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
How we price pre-purchase roof surveys
Several things affect the price of a survey:
- The type of building, from a house to a block or an office
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
- The package you choose: Basic, Standard or Premium
Prices start from £150, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.
What to tell us when you contact us
Some details help us suggest the right survey and price. When you get in touch, it is useful to mention:
- Whether there is a loft hatch, a shared roof or tricky access
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- Where any leaks, stains or damp patches show inside
Unsure which package suits your roof? It’s easiest to ring 07833 053749 or send us an email and describe the roof and what’s worrying you. We will talk you through the options and what they cost.
What we are asked to look at in South Harrow
Viewings rarely include a proper look at the roof. You walk round the rooms, but the roof stays out of sight, and a quick glance from the street misses a lot. Fresh decoration can also cover the marks an old leak left behind, which is why buyers book a closer look before committing.
Look out for signs like these:
- Blistered or split felt on a flat roof
- Roof slopes that look uneven or sagging
- Gutters choked with leaves and moss
- Patch repairs that may hide an ongoing problem
If you own a rental within reach of Northolt Park station, it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it.
Before you book anyone
- What the report includes, and whether it has photos
- What happens after the report arrives
- Whether any drone flown is registered with the CAA
- Their track record with similar roofs

What else we do in South Harrow
How the survey works
On the day, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. Most surveys take an hour or two at a typical house, with time for the loft where it can be reached. In South Harrow, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We help you pick the package that suits the property.
- A date is booked on a weekday, Saturday or Sunday.
- 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.
- We send the report with recommendations ranked by urgency, ready for you to discuss with the seller or agent.
Getting ready for the survey
