Drone roof surveys for homes and businesses in Harmer Green
Tall, steep, large or fragile roofs can’t always be inspected up close. Our drone roof survey gets a camera close to them without anyone climbing. You see slates, ridges, chimneys, valleys and gutters in detail, including slopes that cannot be seen from the street. Everything we find goes into a written report with photos. It’s also a good option where walking on the roof could break slates or tiles. If we can’t fly, we tell you why. We survey valleys and parapet gutters, tall and steep roofs and flat roofs on upper floors, and common reasons people get in touch are worn lead at chimneys and walls and blistered or cracked flat roof coverings.
Villages like Harmer Green frequently stand in open country, where wind can be strong. A small drone can’t fly safely in high wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What affects the cost of drone roof surveys
Several things affect the price of a survey:
- Which survey package you book
- Roof area
- Commercial roofs and larger buildings
- Chimneys, valleys, parapets and other details
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Helping us price your survey

Questions from Harmer Green
Does a conservation area affect roof work in Harmer Green?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover smaller places like Harmer Green?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will you go up on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
What happens if the weather is bad?
The flight waits for better weather. Wind and heavy rain are the two things that ground a small drone, so a new date is agreed with you, or look from other safe viewpoints if you’d rather.
What’s the best way to book?
To book, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Do drone rules differ 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 the airspace for your address and apply where needed.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Leave it or get it looked at?
A drone survey disturbs nothing on the roof. Nothing is cracked or dislodged by footsteps, so you see the roof exactly as it is. In a small place like Harmer Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
For a price for your roof in Harmer Green, ring 07833 053749 or drop us an email with the address and some details. The price is agreed before a date is set.

What we do, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes roughly 1–2 hours for most homes, with the pre-flight checks included, and longer for big commercial roofs. Cottages and farmhouses around Harmer Green frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- First comes the address, plus a note of what worries you about the roof.
- Airspace restrictions are checked and permission sought where needed.
- We assess the conditions and the take-off spot first.
- We fly the sub-250g drone close to the roof and photograph each area.
- You receive a written report with the photos and our recommendations.
Before we arrive
- Tell us about parking before the day
- For a flat or shared roof, check access with whoever owns or manages the building
- Jot down any questions you want answered

Advice
Airspace, weather and Harmer Green roofs
Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. We fly a sub-250g drone and are a CAA-registered drone operator (Flyer ID and Operator ID). Open category rules keep flights below 120 m (400 ft) and the drone within sight at all times.
Digswell House, about 1.5 miles south-west, is one of the historic houses in the wider area around Harmer Green. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. If you run a business near Howard Centre, thermal images can show trapped moisture across a wide commercial roof. The streets around a church like Digswell Village Church are often among the oldest in a place, and if you own one of the older houses nearby, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Harmer Green is about 2 miles north of Welwyn Garden City, in Hertfordshire.

How the survey changes by roof type
Flat roofs on tall buildings
Flat roof coverings wear out at different rates. We record the signs of age we can see.
Large commercial roofs
Big roofs on offices, warehouses and units take time to inspect. The drone covers the roof area by area, so nothing is skipped.

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
