About our thermal roof survey in Codicote Bottom
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there is safe access. Typical surveys look at ceilings that feel colder in places and damp around roof outlets and upstands, on commercial roofs, pitched roof slopes and loft conversions.
Somewhere as small as Codicote Bottom, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what can’t be reached safely. Weather and airspace are looked at ahead of the visit. Steep slopes and tall chimney stacks are where a close-up view adds the most.
If any part of the roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

Roof by roof
Felt and asphalt flat roofs
Felt and asphalt sit tight to the layers below, which frequently helps the camera pick up differences. Any patterns are checked with moisture readings.
GRP fibreglass roofs
Glossy GRP can reflect heat. We allow for reflections and confirm findings with moisture readings.
Codicote Bottom questions
Is my home in Codicote Bottom listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Will you come out to Codicote Bottom?
Yes, Codicote Bottom is on our map. Villages and rural addresses get the same survey as a town house.
Will you go up on the roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. We record the conditions in the report, so you know how much weight to give the images.
How do I arrange a thermal roof survey in Codicote Bottom?
It is easiest to ring 07833 053749 or drop us an email. Let us know the address and a little about the roof. Surveys run on weekdays, Saturdays and Sundays.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
How the survey works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older rural homes like those around Codicote Bottom can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- If it is not your property yet, arrange access through the agent
- Mention any parking restrictions on your street
- Check pets are kept safely away

Tips that help
There is plenty you can do without going near the roof. What helps most:
- Keep dated photos of any marks on ceilings
- Move stored items away from the loft hatch
- Clear leaves from outlets and gutters each autumn
- Tell us where and when you’ve seen damp or stains
Where a pattern can’t be confirmed, the report says what could help, for example electronic leak detection or a roofer opening up a small section.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.

What else we do in Codicote Bottom
Flying and imaging in Codicote Bottom
If your survey includes the drone, the flight is checked against the Drone Safety Map first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
Take a building like Codicote Church of England Primary School: a drone or thermal camera can show a large roof in a single visit. If you run a business near Howard Centre, large commercial roofs are often easiest to see by drone or thermal camera.
Codicote Bottom is about 4 miles north-west of Welwyn Garden City, in Hertfordshire. We survey roofs in Codicote Bottom and the rest of Hertfordshire, as part of our work across London and South East England. Our area takes in places right across Hertfordshire. London is in our area too.

When to book a survey in Codicote Bottom
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
Typical things we’re asked to look at include:
- Damp that repairs haven’t cured
- Wet areas near outlets and upstands
- Damp where roofs meet walls and chimneys
- Ceilings that feel colder in places
Historic houses such as Shaw's Corner, about 1.3 miles south-west, show how far back building around Codicote Bottom goes. Aerial photos and thermal images let an old roof be checked without anyone disturbing it.
Before you book any roof surveyor

DIY checks: what’s safe
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
