Drone Roof Survey in Welwyn
A careful look at the roof at your property in Welwyn, and put it all in a report with photographs.
- Standing water on a flat roof
- Vegetation in valleys and gutters
- Gaps where slates or tiles have gone
How a drone roof survey works in Welwyn
Some roofs are hard or unsafe to reach. A drone takes close-up photographs of those roofs from the air. It shows coverings, ridges, chimneys, valleys and gutters clearly. Everything we find goes into a report with photographs. It’s also a good option where walking on the roof could break slates or tiles. If we cannot fly, we tell you why. We are often asked to look into debris building up in hidden gutters and ridge pieces that have lifted, across flat roofs on upper floors, large and complex roofs and tall and steep roofs.
Even in a smaller place like Welwyn, there may be airfields or restrictions nearby, so the Drone Safety Map is checked before any flight. Exposed sites can be windy, and a small drone can’t fly safely in strong wind, while thermal imaging also works best with little wind. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Practical tips
These tips come from what we see on roofs every week:
- Tell next door if the drone will be near their property
- Share the postcode so we can check for restrictions
- Book early if you are near an airport
- Mention anything you’ve noticed on the roof
Your report arrives by email, including the close-up photos taken by the drone. Findings are set out in plain English, with recommendations prioritised by urgency where relevant.
Plan a drone survey every few years for tall or large roofs. Regular photos make changes easy to spot, and early repairs keep water out.
Prices for drone roof surveys in Welwyn
A few things affect what a survey costs:
- The height of the building and how the roof can be seen safely
- Whether it’s a home or a commercial building
- Whether thermal imaging or a drone is needed
- Extra roofs, like extensions, dormers or garages
All our prices include VAT. Our price is from £400, including VAT. You’ll know the price for your roof before booking.
What we need to know
To price your survey accurately, we will ask about:
- Any photos you have, taken from ground level or a window
- Your timetable, like an exchange date
- Any marks or damp showing indoors
- What made you get in touch

What a drone roof survey looks like in Welwyn
The drone we use is under 250g, flown by a CAA-registered operator with a Flyer ID and Operator ID. Flights in the open category stay under 120 m (400 ft), with the drone kept in sight. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
For businesses in and around places such as Howard Centre, large commercial roofs are often easiest to see by drone or thermal camera. For site and facilities teams at buildings such as Monk's Walk School, big roofs are where aerial photos and thermal images show the most at once. The streets around a church like Parish Church of St Mary are often among the oldest in a place, and if yours is one of the older homes nearby, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.

What we look for on each type of roof
Flat roofs on tall buildings
Outlets, edges and roof plant are common problem areas. They’re all captured in close-up.
Chimney stacks
The drone shows the outside of the stack, not a flue, gas or sweep inspection. We’ll say if a specialist is needed.
What we do, step by step
The visit has one job: to see as much of the roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. The visit normally takes about 1–2 hours for most homes, with the pre-flight checks included, and longer for big commercial roofs. A visit to a smaller place like Welwyn is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We start with the address and what you’d like checked.
- We check the airspace and seek any permission needed.
- Before take-off, the wind, the weather and the launch spot are checked.
- The drone photographs the roof closely, kept in sight throughout.
- We email the report with close-up photos and recommendations.
Preparing for the visit
- Leave a clear route to the loft
- Keep pets inside or away from the areas we’re looking at
- Find any records of previous roof work

Leave it or get it looked at?
Planning roof work without seeing the roof is a gamble. You get photographs of every part we can see, with recommendations prioritised by urgency where relevant. That helps you put the work in order. On a bungalow or cottage around Welwyn, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. You’ll know the price for your survey before booking.
What you get with us

Questions from Welwyn
Is Welwyn within the area you cover?
Yes. Welwyn 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.
Does a conservation area affect roof work in Welwyn?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Can you fly a drone near an airport?
Flight restriction zones around protected airports need permission from the airport or air traffic control before any flight. We check the airspace for your address and seek permission where it is needed. If it is not given, we inspect by other means.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Let us know about it when booking and we will explain what’s needed.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when you book.
What happens if the weather is bad?
Bad weather means no flight. A small drone cannot fly safely in strong wind or heavy rain, so we’d move the date with you.
