Thermal imaging roof survey in Codicote, Hertfordshire

Thermal roof survey in Codicote: what you get
What a thermal camera can show depends a lot on the weather. A sunny day before the survey, a dry roof surface and little wind all help. Rain, wind and cloud can all make the patterns weaker. We talk through the forecast when booking, and our report notes the conditions and how they affected what we saw. We survey pitched roof slopes, loft conversions and ceilings below the roof, and the problems we’re asked to look at most are leaks far from where the stain appears and possible trapped moisture under a flat roof covering.
Even in a smaller place like Codicote, there may be airfields or restrictions nearby, so every drone flight starts with a check of the Drone Safety Map. Open ground can mean stronger wind, which also affects whether a small drone can fly. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Airspace, weather and Codicote roofs
Shaw's Corner, about 1.7 miles south-west, is one of the historic houses in the wider area around Codicote. If you own one of the older houses, expect a mix of original materials and later repairs on the roof. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
The streets around a church such as Parish Church of St Giles 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 often shows up clearly on a thermal image. If you look after a shop, office or commercial unit, for example near Howard Centre, large commercial roofs are often easiest to see by drone or thermal camera. If you look after a building such as Codicote Church of England Primary School, big roofs are where close-up aerial shots and thermal images show the most at once.
Codicote is about 4 miles north-west of Welwyn Garden City, in Hertfordshire. Houses, flats, blocks and commercial buildings in Codicote can all book thermal roof surveys, with a written report and photographs every time. We cover towns and villages across Hertfordshire, large and small. Our London page covers surveys nearby.

What we do, step by step
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely. Most surveys take roughly 1–2 hours at most homes; commercial roofs usually need 3–4 hours. In a smaller place like Codicote, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside, while taller roofs may need other vantage points or the drone where it applies.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Mention any parking restrictions on your street
- Leave side gates unlocked
- Agree roof access with the managing agent if it’s shared
Arrange a survey
Not sure which survey you need? The easiest way is to call 07833 053749 or email us and describe the roof and why you want it surveyed. We will talk you through the options and what they cost.
Related advice
What we look for on each type of roof
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Why act early in Codicote
Wet insulation under a flat roof does not dry out on its own while the covering stays on. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. On a bungalow or cottage around Codicote, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
Prices start from £400, including VAT. The final price depends on the size and height of the roof, how it can safely be seen and which survey you book.

Practical tips
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Ask us about the forecast if rain is expected
- Keep outlets and gutters clear to stop water sitting
- Check from the ground or a window, never by climbing
- Tell us where and when you’ve seen damp or stains
We note the weather and surface conditions, and how they may have affected the results. That way you know how much weight to give each finding.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.

What affects the cost of thermal roof surveys
What a survey costs depends on the time and equipment it needs. That comes down to:
- The shape of the roof and its details
- Extensions, dormers and garages with roofs of their own
- Roof area
- Which survey package you book
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.
Helping us price your survey
What helps most when you contact us:
- How the loft is reached, if there is one

- What kind of property and roof it is
- What made you get in touch

Common questions in Codicote
Do you cover smaller places like Codicote?
We do. Villages and rural addresses get the same survey as a town house.
Is Codicote in the area you cover?
Yes. We work right across London and South East England, and Codicote is part of that. Just call 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
Does thermal imaging work on slate and tile roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
Does thermal imaging detect leaks directly?
The camera does not see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
How many surveys have you done?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of clients are satisfied.
