Drone roof surveys for homes and businesses in Cannon Hill
A drone can see more than your roof, so we take care. We keep the camera on the roof we’re surveying, not on neighbouring homes and gardens. If your roof is shared, a word with next door beforehand helps. We inspect only what the owner has asked us to. Each flight is kept short and stays focused on the roof we are there to survey. We’re often asked to look into ridge pieces that have lifted and lifted or split lead flashings, across flat roofs on upper floors, chimney stacks and fragile roofs.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. Images are taken to show the roof we are surveying, with care for neighbours’ privacy, in Cannon Hill as anywhere. Let us know about the building and access when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Cannon Hill: your questions answered
Is drone flying allowed in Cannon Hill?
It depends on the exact address and the weather on the day. 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. Before any flight, we check the Drone Safety Map for airspace restrictions. The flight also waits for calm, dry weather.
Is parking a problem for a survey in Cannon Hill?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How long is the visit?
It normally takes about one to two hours at a house, including the airspace and weather checks before take-off. You will then get the report by email, on the timescale of your package.
What happens after the survey?
You will get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.

Drone roof surveys in Cannon Hill: local notes
We fly a sub-250g drone and are a CAA-registered drone operator (Flyer ID and Operator ID). Open category rules keep flights below 120 m (400 ft) and the drone within sight at all times. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
Southside House lies about 1.2 miles north-west, so building around Cannon Hill goes back a long way. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. If your house is among the older ones in the streets near St James Merton, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Cannon Hill is about 1 mile north-west of Morden, in Greater London. Roofs in Cannon Hill get the same thorough look as anywhere else in Greater London. Cannon Hill is one of the towns and villages in Greater London where we work for drone roof surveys. You can also see our page for London.

What a survey costs
Prices always include VAT. The things that change the price are:
- The shape of the roof and its details
- The roof’s overall size
- How tall the building is and how easy the roof is to see
- The type of building, from a house to a block or an office
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 need to know.
What to let us know when you contact us
Before you get in touch, it helps to have:
- The reason for the survey, like buying, a leak or storm damage
- Any marks or damp showing indoors
- Whether there’s a loft hatch, a shared roof or tricky access
- Pictures from the garden or a window, if you have them
To arrange a survey, ring 07833 053749 or send us an email with the address and what you’d like to know about the roof. We will confirm the price before you book.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Common roof problems in Cannon Hill
Chimney tops take the worst of the weather. From ground level, you rarely see cracked flaunching or loose pots. A drone gets close enough to see them in detail.
It is worth booking a survey if you’ve seen:
- Flashings that have come away
- Damage after a storm that cannot be seen from below
- Vegetation in valleys and gutters
- Coverings that have slipped high up on the roof
Take a building like Hillcross Primary School: thermal images can show where wet insulation sits under a big flat roof.
Choosing a roof surveyor
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Are they insured for the work?
- When you will get the report
- Whether you get a written report with photos
Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Share the postcode so we can check for restrictions
- Check the loft can be reached
- Let neighbours know about the flight if your roof is shared
- Be ready to move the date if the weather turns
Keep the photos with your property records. They’re a useful baseline for future surveys.
Keep the roof space ventilated. Poor airflow lets condensation build up, and it is something only an inside check will show. Make sure insulation does not block the airflow.
How it works
The visit has one job: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit typically takes roughly 1–2 hours at a house, including the airspace and weather checks before take-off. In a London area like Cannon Hill, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- First, we check whether a drone is the right tool.
- A visit is booked for a weekday, Saturday or Sunday, weather permitting.
- The roof is photographed from the air, with the camera kept on your property.
- Where there’s safe access, we check the loft as well.
- Everything is written up, with the aerial photos and our advice.
Getting ready for the survey
- Find any records of previous roof work
- Tell us about any leaks, stains or damp patches you know of
- If the roof is shared, arrange access with whoever manages the building
How to book
Booking is simple: just call 07833 053749 or send us an email and give us some details about the property and we’ll recommend the right survey. The price is agreed up front.
