Thermal imaging roof survey in Alfold Bars, West Sussex
Thermal imaging to find moisture and heat loss patterns in a roof for Alfold Bars, from an experienced roof surveyor. You get a clear written report with photographs.
- Thin or uneven insulation in the roof
- Damp that repairs haven’t cured
- Wet areas near outlets and upstands
Tips from our surveys
Nothing here needs a ladder. Our suggestions:
- Take photos of stains as they appear, so we can compare
- Remember the conditions on the day affect the results
- Move stored items away from the loft hatch
- Note where damp appears and after what weather
After the visit, we put the thermal images, photographs and moisture readings into one report. We explain what each image may mean, with our recommendations. Premium reports are sent the same day.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
Thermal roof survey in Alfold Bars
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you can’t normally tell from the surface. Moisture readings are then used to check what the camera suggests. If you are worried about areas of a flat roof that may hold water and water getting in at parapets and stacks, a survey will tell you what’s going on.
In a village or hamlet like Alfold Bars, 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. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photo. It records what’s sound as well as what isn’t.

Leave it or get it looked at?
Repeated repairs that do not stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, rather than more guesswork. Where a roof is exposed, as many are in small places like Alfold Bars, driving rain gets into any weakness, and damp in older walls is slow to dry out.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Thermal roof survey starts from £400, including VAT.

Roof by roof
Pitched slate and tile roofs
Slate and tile roofs are often harder to read with a thermal camera, because of the air space beneath. We combine the images with an inspection from the loft where there’s safe access.
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. The camera can give clues to where it is sitting, when the conditions allow.
Drones, thermal imaging and Alfold Bars roofs
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
For an older house near a landmark such as Church of St Nicholas, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Anyone responsible for a site like Loxwood Primary School will know that a view from above covers a wide roof far faster than walking it.

The survey, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. Most visits take an hour or two for most houses; commercial roofs usually need 3–4 hours. Somewhere like Alfold Bars needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, 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 is safe.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- If you are buying, check with the agent that we can get in
- Keep pets out of the way during the survey
- Check the loft hatch can be reached
