Drone roof survey in Tonwell
Tall, steep, large or fragile roofs can’t always be inspected up close. A drone takes close-up photos of those roofs from the air. It shows coverings, ridges, chimneys, valleys and gutters clearly. Everything we find goes into a photo-illustrated written report. It also suits roofs that would be damaged by someone walking on them. Where a flight is not possible, we explain why. We survey flat roofs on upper floors, large and complex roofs and chimney stacks, and common reasons people get in touch are lead work pulling away at abutments and tired mortar and pots at the top of a stack.
Somewhere as small as Tonwell, 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. Weather and airspace are checked ahead of the visit, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the roof, the defects we found and what we recommend.

Airspace, weather and Tonwell roofs

What happens on the day
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect about 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. Rural addresses near Tonwell can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First, we check whether a drone is the right tool.
- A date is fixed, with a fallback in case the weather turns.
- Aerial photos are taken of your roof only, not the neighbours’.
- If the loft can be reached safely, it’s checked too.
- You get photos, findings and clear recommendations.
Before the survey
- Tell us about any leaks, stains or damp patches you know of
- Check the loft hatch can be reached
- For flats, make sure roof access has been agreed
Booking a survey
Not sure which survey you need? It’s easiest to ring 07833 053749 or send us an email and describe the roof and why you want it surveyed. We will explain the options and the price.

What we look for on each type of roof
Flat roofs on tall buildings
Leaks often start at outlets, edges and around plant. They’re all captured in close-up.
Chimney stacks
Leaning stacks and loose pots are easier to judge from above. Each defect is photographed for the report.
When to book a survey in Tonwell
Many roofs are never seen properly from ground level. Rear slopes, valleys and the tops of chimneys are hidden. Problems in those places frequently go unseen until they leak.
People usually book a survey after spotting something like this:
- Eroded pointing on a chimney stack
- Flat roofs on upper floors that hold water
- Lifted or split lead flashings
- Outlets choked with leaves and silt
For site and facilities teams at buildings like Tonwell St Mary's Church of England Primary School, big roofs are where photos from the air and thermal images show the most at once.
Questions to ask before you book
- Which parts of the roof they’ll actually see
- Whether the roof space is looked at, where there is one
- Their insurance cover
- What they will not be able to tell you
Practical tips
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Allow for a change of day in poor weather
- Make sure there’s room outside for the drone to take off
- Allow time for permission if you’re in a flight restriction zone
- Share the postcode so we can check for restrictions
The report gives any roofer you ask to quote a clear brief. The photos show the location and extent of every problem, so their quotes cover the same ground.
Check the loft now and then, with care and a good torch. A drone sees the outside, but the loft shows leaks and condensation from below. Take photos of any changes.
Your questions about drone roof surveys in Tonwell
Are there drone restrictions around Tonwell?
Usually it comes down to two things: the airspace at the address and the weather. Every flight is checked against the Drone Safety Map first. The flight also waits for calm, dry weather.
How do I find out if my home in Tonwell is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Does the weather affect the survey?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so we will agree a new date if the weather is not suitable.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps.
Is Tonwell in your area?
Yes. We cover Tonwell and the rest of Hertfordshire, as part of our work across London and the South East. For a price, ring 07833 053749 or drop us an email.
