Drone roof survey in Cassiobury
They suit tall buildings, steep or large roofs and roofs that are hard to see from the ground. They’re useful where walking on the roof could damage it or is not safe, like old slate, clay tiles or cement sheets. You get close-up views without anyone setting foot on the roof. We check the airspace for your address before the visit. If a drone isn’t the right tool, we’ll say so. Typical surveys look at debris building up in hidden gutters and loose ridge and hip tiles, across large and complex roofs, fragile roofs and valleys and parapet gutters.
Around Cassiobury, older homes can have thin loft insulation and later additions with roofs of their own. A thermal image can show where heat is escaping or where moisture may be trapped, and drone photos show the roof surfaces themselves. Anything that looks like moisture is checked with a meter. Results depend on the weather, so the visit is planned around the forecast.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Landlords, agents and block managers in Cassiobury
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
When you need someone else
A survey is a careful look at the roof, but it cannot do everything. Its limits include:
- A flight where airspace permission is refused
- Roofs and gardens beyond the one we’re surveying
- Whether the roof structure meets design loads
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer. The full list of what we check.
Roof types and parts we check
- Tall and steep roofs
- Large and complex roofs
- Fragile roofs
- Chimney stacks
- Valleys and parapet gutters
- Flat roofs on upper floors
How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two at most homes, and more on a big or complicated roof. Some parts of a survey depend on the weather, so a visit to Cassiobury is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- First, we check whether a drone is the right tool.
- We agree a date, including weekends, subject to the weather.
- We fly over the roof, keeping the camera on the property we’re surveying.
- Where there’s safe access, we check the loft as well.
- You get photos, findings and clear recommendations.
Before the survey
- If it isn’t your property yet, arrange access through the agent
- Keep pets in another room
- Move anything stored under the loft hatch
Booking a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or email us.

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Why act early in Cassiobury
Photos from a drone survey show how the roof looks today. Comparing them with later photos shows what has changed. It is useful for planning maintenance over the years. With lower homes, common in places like Cassiobury, there is little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.
Prices start from £400, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.

Cassiobury: your questions answered
Does a conservation area affect roof work in Cassiobury?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover smaller places like Cassiobury?
Yes, we do. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest, and the report records anything we couldn’t see.
How long does a drone roof survey take?
The visit normally takes about 1–2 hours at a typical home, rising to roughly 3–4 hours on a commercial building. We will confirm what to expect when we arrange the visit.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so whoever owns or manages the building needs to agree access. We inspect only the parts we are allowed to reach.
Are there drone restrictions in central London?
Central London has restricted areas over Hyde Park, the City of London and the Isle of Dogs, where flights need permission from NATS. We check before every flight and seek permission where needed.

Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Move stored items away from the hatch
- Let us know about any leaks or concerns
- Keep a clear space in the garden or drive for take-off
- Allow time for permission if you are in a flight restriction zone
We email the report to you, including the close-up photos taken by the drone. Findings are set out in plain English, and recommendations are ranked by urgency where that helps.
Look at the roof from the ground after strong winds. Pieces of slate or tile on the ground mean something has moved. A drone can show exactly what has moved.
