Airspace, weather and Underriver roofs
Knole House, about 1.6 miles north-west, is one of the historic houses in the wider area around Underriver. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons.
If you look after a building like Sevenoaks Preparatory School, big roofs are where aerial photos and thermal images show the most at once. The streets around a church like Church of St Margaret are often among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps.
Underriver is about 3 miles south-east of Sevenoaks, in Kent. Houses, flats, blocks and commercial buildings in Underriver can all book drone roof surveys, with a written report and photographs every time. Underriver is one of the towns and villages in Kent where we work for drone roof surveys. We also survey roofs in Maidstone.

About our drone roof survey in Underriver
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, such as old slate, clay tiles or cement sheets. The roof is photographed without being disturbed. We check the airspace for your address before the visit. We will tell you if another approach would work better. We survey chimney stacks, flat roofs on upper floors and tall and steep roofs, and people most often book us about lifted or split lead flashings and cracked mortar along the ridge.
Somewhere as small as Underriver, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
If any part of the roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Roof by roof
Steep slate and tile slopes
Steep slopes are hard to inspect safely on foot. From the air, every course of slates or tiles can be seen.
Chimney stacks
Chimney tops are hard to see from the ground. A drone gets close to the pots, flaunching, pointing and flashings, so cracks and gaps are clear.

Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Tell us about it when booking and we’ll plan the survey around it.
Landlords and agents in Underriver book surveys as well as householders. A photo-illustrated written report gives you a clear record of the roof, useful for planning maintenance.
What a drone roof survey does not cover
To be straight with you, a roof survey has limits:
- Whether the roof structure meets design loads
- Flying in a flight restriction zone without the airport’s permission
- Neighbouring roofs the owner hasn’t asked us to survey
If in doubt, ring 07833 053749 or use the contact form and we’ll suggest the right survey before booking. The full list of what we check.
Roofs we survey in Underriver
- Flat roofs on upper floors
- Valleys and parapet gutters
- Tall and steep roofs
- Fragile roofs
- Chimney stacks
- Large and complex roofs
How it works
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes roughly 1–2 hours at most homes, while a commercial roof takes nearer three to four hours. For a village or hamlet like Underriver, the journey is planned in advance: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- First comes the address, plus a note of what worries you about the roof.
- We check the airspace and seek any permission needed.
- On the day, we check the wind, weather and site before flying.
- The drone photographs the roof closely, kept in sight throughout.
- You receive a written report with the photos and our recommendations.
How to prepare
- For a flat or shared roof, check access with whoever owns or manages the building
- Find any records of previous roof work
- Clear the way to the loft hatch
How to book

Advice
Leave it or get it looked at?
From the ground, you’re guessing about most of a tall roof. A drone replaces that guesswork with clear photos. Seeing the problem makes it easier to decide what to do. Outbuildings and barns around Underriver are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

Underriver: your questions answered
Are there drone restrictions around Underriver?
That depends on where the roof is and on the weather. Before any flight, we check the Drone Safety Map for airspace restrictions. The flight also waits for calm, dry weather.
Is my home in Underriver listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
What do I do with the report?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you walk on the roof?
Only where it’s safe to do so. We inspect whatever is safely visible: from ground level, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. Anything we cannot see is noted in the report.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Does the weather affect the survey?
A survey can usually go ahead in light rain. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions aren’t right we’ll arrange another day with you.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
