Drone roof survey in Knockholt: what you get
From the air, the outer surfaces are clear, but it cannot see inside. Where there’s safe access, we look in the roof space too, since that’s where leaks and condensation frequently show first. Together, the two give a fuller picture. Your report shows the drone photos alongside what we saw in the loft. Where the loft cannot be reached safely, we note it. If you’re worried about cracked flaunching or loose chimney pots and slates or tiles shifted by high winds, we can find out what’s behind it.
In a village or hamlet like Knockholt, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Both the forecast and the airspace are checked first. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You will see the good as well as the bad.

Drone roof surveys in Knockholt: local notes
The drone we use is under 250g, flown by a CAA-registered operator with a Flyer ID and Operator ID. In the open category, flights stay below 120 m (400 ft) and within sight. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. You will also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help.
Historic houses like Down House, about 2.7 miles north-west, show how far back building around Knockholt goes. For older roofs nearby, a look from the air or with a thermal camera is a hands-off way to check condition. For an older house near a landmark such as St Katharine's Church, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from above or with a thermal imager helps.
Knockholt is about 4 miles north-west of Sevenoaks, in Kent. We survey roofs in Knockholt and the rest of Kent, as part of our work across London and South East England. Knockholt is one of the places in Kent we cover. Our London page covers surveys nearby.
Surveys in TN14 are booked the same way as anywhere else. Whether your property is on Main Road and Blueberry Lane or anywhere close by, we can help. Neighbouring places we cover for drone roof surveys include Knockholt Pound (1 mile north-east), Halstead (2 miles north-east), Sepham Heath (2 miles north-east), Pratt's Bottom (2 miles north) and Twitton (3 miles east). Larger places within reach include Dartford (11 miles north-east), Sevenoaks (4 miles south-east), Royal Tunbridge Wells (14 miles south-east), Gravesend (14 miles north-east), Tonbridge (11 miles south-east) and Northfleet (13 miles north-east).
What’s near Knockholt
We work in homes and buildings around The Three Horseshoes pub, among other places. For rail, the closest station is Knockholt station, roughly 2.7 miles north-east. Other landmarks nearby include Orpington Hospital (3.6 miles north) and Otford Heritage Centre (3.9 miles east). The countryside around Knockholt includes Betsom's Hill and Downe Bank.
Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

Landlord and commercial surveys in Knockholt
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
What a survey costs
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Commercial roofs and larger buildings
- The use of thermal imaging or a drone
- The number of roofs, including extensions and garages
- Which survey package you book
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, including VAT. We will tell you which package suits the questions you have.
Getting in touch
We’ll usually ask about:
- What’s prompted the survey
- The kind of building and roof involved
- Access details, such as a loft hatch or a shared roof
- Where water is showing inside, if it is
Not sure which survey you need? It’s easiest to call 07833 053749 or send us an email and describe the roof and why you want it surveyed. We’ll talk you through the options and what they cost.
Different roofs, different checks
Flat roofs on tall buildings
Felt often lasts around 15 to 20 years, EPDM rubber around 30 to 50 and GRP up to about 30. We record the signs of age we can see.
Chimney stacks
The drone shows the outside of the stack, and it is not a flue or gas safety check. We’ll say if a specialist is needed.
How the survey works
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours at a house, including the airspace and weather checks before take-off. For a village or hamlet like Knockholt, the journey is planned beforehand: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- You give us the address so we can check the airspace.
- Where a flight restriction zone or restricted area applies, we seek permission first.
- We assess the wind, the weather and the surroundings before take-off.
- The drone captures close-up photos of the coverings, chimneys, valleys and gutters.
- We email a written report with the photos and our recommendations.
Before we arrive
- Check the loft hatch can be reached
- Have any questions written down, so nothing gets missed
- Have keys ready for side gates, garages or roof access doors
Getting a price
Booking is simple: just ring 07833 053749 or email us and give us some details about the property and we will point you to the right survey. We confirm the price before anything is booked.
Advice
Why get it checked now?
Close-up photos make conversations with roofers clearer. You can show exactly where the problem is, which helps when you ask for quotes. Older cottages and farmhouses around Knockholt can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.

Common questions in Knockholt
Is Knockholt within the area you cover?
Yes. Knockholt is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Can you fly a drone over a roof in Knockholt?
It depends on the exact address and the weather on the day. Every flight is checked against the Drone Safety Map first. The flight also waits for calm, dry weather.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Will I get photos?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Does the weather affect the survey?
It can, depending on the survey. Drones can’t fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.
