Thermal roof surveys for homes and businesses in Chaldon
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 talk through the forecast as you book, and our report notes the conditions and how they affected what we saw. We survey ceilings below the roof, insulated roof spaces and commercial roofs, and the problems we are asked to look at most are water that travels before it shows and damp that repairs haven’t cured.
Somewhere as small as Chaldon, 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. Both the forecast and the airspace are checked first, and the journey is planned ahead of time. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, and recommendations are put by urgency where it matters.

Useful tips for Chaldon property owners
These tips come from what we see on roofs every week, before and after a survey:
- Heat the home normally on the days before
- File the images with your roof records
- Talk to us about the weather when booking
- Note where damp appears and after what weather
We note the weather and surface conditions, and how they may have affected the results. That way you know how much weight to give each finding.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Why it’s worth a survey now in Chaldon
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Older and listed buildings around Chaldon may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.

Thermal roof surveys around Chaldon
An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
Anyone responsible for a site like St Peter and St Paul CofE Infant School will know that a view from above covers a wide roof far faster than walking it. If you live in an older home near Church of St Peter and St Paul, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Chaldon is about 1 mile south-west of Caterham, in Surrey. In Chaldon, as across Surrey, every roof gets the same careful survey. Our area takes in places right across Surrey, from the larger towns to small villages. We also survey roofs in Crawley.

How it works
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Older roofs in small places like Chaldon can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- 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.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Make sure we can get to the back of the property
- If the roof is shared, arrange access with whoever manages the building
- Note where any stains or damp appear

FAQs for Chaldon
Will you come out to Chaldon?
We do. Villages and rural addresses get the same survey as a town house.
Is Chaldon in the area you cover?
Yes, Chaldon is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
What does a thermal roof survey show?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, so you can see what we mean.
Can a thermal survey trace a roof leak?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. Where it can’t be pinned down, the report suggests a next step, such as electronic leak detection.
Rented homes, blocks and businesses
Letting agents and landlords in Chaldon book surveys as well as householders. The report gives you a dated record of the roof, with photographs.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we will plan the visit with that in mind.
Roof by roof
Pitched slate and tile roofs
Thermal images of a pitched roof can still show heat loss patterns and some damp areas. We explain what can and can’t be read from them.
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We combine a visual check of cracks with the thermal images around them.
Common roof problems in Chaldon
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
It’s worth booking a survey if you’ve seen:
- Damp that repairs haven’t cured
- Wet areas near outlets and upstands
- Water that travels before it shows
- Gaps in loft insulation
If you run a business near The Belfry, thermal images can show trapped moisture across a wide commercial roof.
