How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take an hour or two for most houses; commercial roofs usually need 3–4 hours. Somewhere like Old Knebworth needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We start by checking the airspace and any restrictions at your address.
- We arrange any permission that’s needed before we fly.
- On the day, we check the weather and the site before flying.
- We fly the drone close to the roof to photograph it in detail, always in sight.
- We email a written report with the photos and our recommendations.
Before we arrive
- Check we can get to the back of the property
- If you are buying, check with the agent that we can get in
- For a flat or shared roof, check access with the building owner or managing agent
Book a survey
A quick phone call is typically the easiest start: call 07833 053749 or send us an email and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
Advice
Drone roof survey in Old Knebworth: what you get
Drone roof survey starts from £400, including VAT. A drone inspection, where applicable, is also part of our Premium Survey, with a same-day report, structural analysis and an in-person consultation. It also includes a follow-up after 12 months. If a drone will not help on your roof, we’ll say so. You get a written report with the close-up photos from the flight. Common reasons to book are blistered or cracked flat roof coverings and lead work pulling away at abutments, on valleys and parapet gutters, fragile roofs and large and complex roofs.
In a small place like Old Knebworth, open ground can mean strong wind. A small drone can’t fly safely in strong wind or a downpour, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
After the visit, you get a photo-illustrated written report, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

What we are asked to look at in Old Knebworth
Not every roof can take a person’s weight. Old slates and clay tiles crack underfoot, and some sheet roofs are fragile. A drone lets us see them closely without touching them.
We’re often asked to look at:
- Hidden gutters full of leaves
- Tired mortar and pots at the top of a stack
- Coverings that have slipped high up on the roof
- Standing water on a flat roof
For site and facilities teams at buildings such as Barnwell School, a drone or thermal camera can show a large roof in a single visit.
Choosing a roof surveyor
- Their drone registration, if they fly one
- Whether you get a written report with photos
- Whether the inside of the roof is included
- Which parts of the roof they’ll actually see
Your questions about drone roof surveys in Old Knebworth
Is Old Knebworth within the area you cover?
Yes, we do. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Is drone flying allowed in Old Knebworth?
Normally 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 long is the visit?
Time on site depends on the roof, but most surveys take about 1–2 hours at most homes, and more on a big or complicated roof. The written report follows by email.
What’s in the survey report?
Written findings with photos, covering the condition of the roof, the defects we found and what we recommend, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Will you walk on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where it applies.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Can you survey at the weekend?
Surveys run on any day of the week. To arrange a date, call 07833 053749 or drop us an email.

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
