Thermal roof survey in Chorleywood
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. It is important to know that the camera shows temperature, not water, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’ve noticed cold spots on ceilings under the roof and areas losing heat at the eaves and junctions, a survey will tell you what’s going on, whatever the roof.
Even in a smaller place like Chorleywood, 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, while thermal imaging also works best with little wind. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Why act early in Chorleywood
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Looking now, while the damage may still be limited, keeps more options open. In a smaller place like Chorleywood, wherever a roof is exposed, a loose ridge or flashing doesn’t stay loose for long. Wind gets under it and lifts more, and water follows.
Every price we give includes VAT, and the report is not charged as an extra. Prices start from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Chorleywood: your questions answered
Do you cover Chorleywood?
We do. Every survey there gets the same written report with photos.
How do I find out if my home in Chorleywood is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will the survey show heat loss through my roof?
The camera can point to heat loss and gaps in insulation. We do not give energy ratings or heat loss calculations, but the report shows where to look more closely.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and cannot tell you, and we check them with a visual inspection and moisture readings.
What can thermal imaging tell me about my roof?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
Which days do you carry out surveys?
Surveys run seven days a week. To find a day that suits you, phone 07833 053749 or send us an email.
When you need someone else
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- A formal energy assessment
- What’s inside walls or under coverings, without opening up
- Seeing water directly, as the camera shows temperature, not moisture
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we will tell you before you book. What our survey covers.

How the survey changes by roof type
Felt and asphalt flat roofs
Felt and asphalt roofs frequently show wet areas as patches that differ from the rest. We check those patches with moisture readings.
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there is a pattern around them.
Thermal roof surveys in Chorleywood: local notes
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. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
Chenies Manor House, about 2.1 miles north-west, is one of the historic houses in the wider area around Chorleywood. Aerial photos and thermal images let an old roof be checked without anyone disturbing it. If you look after a building such as Christ Church Chorleywood CofE School, thermal images can show where wet insulation sits under a big flat roof. If you own one of the older houses in the streets near Christ Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

How we price thermal roof surveys
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Whether thermal imaging or a drone is needed
- The size of the roof
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
Every price we give includes VAT. Thermal roof survey starts from £400, including VAT. We confirm the price for the job before booking.
Booking your survey
A little information up front helps. Please include:
- Where water is showing inside, if it is
- What made you get in touch
- Any photos you have, taken from the ground or a window
- Whether there’s a loft hatch, a shared roof or tricky access
Once you know what you need, phone 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.
How it works
After the inspection, everything we found is written up as a written report with photos, emailed to you. As for time on site, it normally takes about one to two hours for a house, rising to roughly 3–4 hours on a commercial building. Some parts of a survey depend on the weather, so a visit to Chorleywood is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- First we discuss the roof, any damp and the forecast for the visit.
- 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.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Keep pets out of the way during the survey
- Make a note of anything you’d like us to look at
- Let us know where we can park nearby
Book a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine. To send them or to book, ring 07833 053749 or send us an email.

Tips that help
These tips come from what we see on roofs every week:
- File the images with your roof records
- Do not switch the heating off ahead of the visit
- Keep a record of when stains appear
- Check outlets after heavy rain
After the visit, we put the thermal images, photographs and moisture readings into one report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
