Thermal roof survey in Coldharbour
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it’s warm inside and cold outside. The report shows the images and explains what they may mean. We do not give energy ratings or heat loss calculations. We are often asked to look into damp that repairs haven’t cured and patches of heat loss across the roof, on commercial roofs, loft conversions and insulated roof spaces.
In a village or hamlet like Coldharbour, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Both the forecast and the airspace are checked first. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put by urgency where it matters.

What a thermal roof survey looks like in Coldharbour
If your survey includes the drone, the flight is checked against the Drone Safety Map first. Older houses across Surrey frequently have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
Around Coldharbour, as everywhere, small roof faults are simplest to sort before they let water in. For an older house near a landmark like Christ Church, older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

- Ceilings below the roof
- Pitched roof slopes
- Loft conversions
- Flat roofs
- Commercial roofs
- Insulated roof spaces
What we do, step by step
We look at the roof from outside and, where it is relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes an hour or two at a typical home, rising to roughly 3–4 hours on a commercial building. Somewhere as small as Coldharbour, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- 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.
Preparing for the visit
- Make sure we can get to the back of the property
- Buyers: confirm access with the estate agent or seller
- Agree roof access with the managing agent if it’s shared
Booking a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.
Advice
Coldharbour questions
Do you cover smaller places like Coldharbour?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Is Coldharbour in the area you cover?
Yes. Our area covers London and the South East, and Coldharbour is part of that. You can ring 07833 053749 or drop us an email with the address and a few details, and we will talk through which survey suits.
How long does the survey take?
That depends on the size and shape of the roof, but most surveys take between one and two hours on an ordinary house, and more on a big or complicated roof. The written report follows by email.
What’s the best way to book?
It’s easiest to call 07833 053749 or use the contact form. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run on weekdays and at weekends.
Is thermal imaging useful on pitched roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we’ll agree the details when you book.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Roof by roof
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. That makes the survey more focused.
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. We check those patches with moisture readings.

For landlords and managing agents
If you own several properties, you can book surveys for several addresses. To arrange surveys for several addresses, ring 07833 053749 or email us.
Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the visit with that in mind.
Why it’s worth a survey now in Coldharbour
Thermal images can suggest the extent of wet areas without cutting into the roof. That helps you and your roofer decide what really needs replacing. In a place like Coldharbour, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Prices start from £400, including VAT.
