Thermal imaging roof survey in Flaunden, Hertfordshire
Thermal imaging to find moisture and heat loss patterns in a roof for Flaunden, from an experienced roof surveyor. You get a clear written report with photos.
- Heat escaping through the roof
- Water getting in at parapets and stacks
- Leaks far from where the stain appears
How we price thermal roof surveys
To price your survey, we look at:
- Basic, Standard or Premium
- How tall the building is and how easy the roof is to see
- The roof’s overall size
- The use of thermal imaging or a drone
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, inc. VAT. We will tell you which package suits the questions you have.
What to let us know when you get in touch
Before you get in touch, it’s useful to have:
- Pictures from the garden or a window, if you have them
- What’s prompted the survey
- Dates you are working to, such as exchange
- Where the property is, with the postcode
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.
How a thermal roof survey works in Flaunden
Thermal imaging works best in the right conditions. A sunny day before the survey, a dry roof surface and little wind all help. Rain, a strong wind or heavy cloud can make the images less clear. We’ll discuss the weather with you when booking, and our report notes the conditions and how they affected what we saw. Common reasons to book are water getting in at parapets and stacks and possible trapped moisture under a flat roof covering, on flat roofs, commercial roofs and ceilings below the roof.
In a village or hamlet like Flaunden, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what cannot be reached safely. Weather and airspace are looked at ahead of the visit, and the journey is planned ahead of time. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

DIY checks: what’s safe
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.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
The survey, step by step
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes about one to two hours on an ordinary house, and about three to four hours for a commercial roof. For a village or hamlet like Flaunden, the journey is planned ahead of time: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s safe.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- For a flat or shared roof, check access with whoever owns or manages the building
- Note where any stains or damp appear

Thermal roof surveys in Flaunden: local notes
The wider area around Flaunden has a long history of building, with Chenies Manor House about 1.6 miles south. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If you live in an older home near Church of St Mary Magdalene (Church of England), steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from the air or with a thermal camera helps. For site and facilities teams at buildings such as St Clement Danes School, thermal images can show where wet insulation sits under a big flat roof.

What happens if roof problems are left?
A poorly insulated roof loses heat year after year. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. Older and listed buildings around Flaunden may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We will give you the figure before anything is booked.
