Pre-purchase roof survey in Greenhill, Greater London
A roof survey before you buy a house or flat in Greenhill, using drones and thermal imaging where applicable. Get in touch for a price.
- Loose pots and cracked flaunching
- Damp timbers or stains in the loft
- Sagging ridge lines or uneven roof slopes
Different roofs, different checks
Lead flashings and valleys
Many older houses have lead in their valleys and hidden gutters. Worn or cracked lead lets water straight into the roof, and missing lead is not unknown, as it is a target for thieves.
Clay and concrete tiles
Older homes in the South East often have handmade clay tiles, including Kent peg tiles on some. Rotten pegs let tiles slide.
Pre-purchase roof survey in Greenhill
Many older houses carry decades of roof repairs. Corroded nails let slates slide, valley linings wear thin and chimney mortar erodes. Little of that is easy to judge from the pavement on a viewing. We look closely and record what we see, with photographs that show you exactly where. Each finding is explained in plain words, so it’s clear what it means for your purchase. We survey the roof space, gutters and downpipes and natural slate, and the problems we’re asked to look at most are cracked flaunching or crumbling chimney pointing and bitumen or mortar used in place of proper repairs.
London terraces and converted houses frequently share a roof line, chimney stacks and gutters with the house next door. For a purchase or a new roof in Greenhill, that shapes what can be checked: we inspect what we’re given access to and can see safely, which may not include a neighbour’s side. If it’s a flat, the lease typically sets out who is responsible for the roof.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What a pre-purchase roof survey looks like in Greenhill
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. About 1.1 miles north-west lies Headstone Manor, a reminder of how long the area around Greenhill has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
For a London address like Greenhill, it helps to know about controlled parking before the day, along with any off-street space. The streets around a church such as Church of St John the Baptist are often among the oldest in a place, and if you own one of the older houses nearby, older patch repairs can hide behind a tidy front slope, and the survey looks past them. If you own a rental within reach of Harrow-on-the-Hill station, a written report helps before buying a rental or paying for a new roof on one.
Greenhill is about 1 mile north-east of Harrow, in Greater London. We survey roofs in Greenhill and the rest of Greater London, as part of our work across London and the South East. Our area takes in places right across Greater London, large and small. Our London page covers surveys nearby.

Tips from our surveys
Some practical points come up on survey after survey. They apply to most roofs:
- Find out whether the roof has been replaced or patched
- Book once your offer is accepted
- Notice patches of new decoration in top-floor rooms
- Check the lease for roof repair responsibilities
It’s worth sharing the report with your solicitor so they can raise enquiries with the seller’s side. Past repairs, re-roofing and any records of that work are all fair questions.
Look in the loft now and then, with care and a good torch. Watch for stains, damp timbers and chinks of daylight. Take photos so you can show whoever looks at it.
Your questions about pre-purchase roof surveys in Greenhill
Is parking a problem for a survey in Greenhill?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we’ll work around them.
Are there drone restrictions around Greenhill?
Typically it comes down to two things: the airspace at the address and the weather. 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. Before any flight, we check the Drone Safety Map for airspace restrictions. Strong wind or heavy rain also stops a small drone flying.
At what stage of buying should I get the roof surveyed?
After your offer is accepted and before you exchange contracts. That way you can still act on what we find, whether that means asking questions or negotiating.
Is your roof survey a RICS survey?
No. We survey the roof, not the whole building, and it is not a RICS home survey. It complements one rather than replacing it.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Is Greenhill in your area?
Yes. We survey roofs across London and South East England, and that includes Greenhill.
Will you climb onto the roof?
Only where it’s safe to do so. We inspect from the ground, from windows and vantage points, from the loft and from the roof itself where safe. On Premium, a drone is used where it applies.
Can I check my roof myself?
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How it works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes between one and two hours at the house you’re buying, depending on its size and how much of the roof can be seen. For a visit in Greenhill, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it is safe, the roof itself.
- You book once your offer is accepted and let us know the address and your timetable.
- We agree a time and how we will get in, including the loft.
- We inspect the roof from ground level, windows, the loft and the roof itself where it is safe.
- Coverings, ridges, valleys, flashings, chimneys and gutters are checked and photographed.
- Your report arrives by email, with photos and recommendations prioritised by urgency.
Preparing for the visit
- If you’re buying, check with the agent that we can get in
- For a flat or shared roof, check access with the freeholder or managing agent
- Note where any stains or damp appear
