The Chart Thermal Roof Survey
Thermal roof surveys in The Chart and the rest of Surrey. Surveys run on weekdays and at weekends.
- Damp around chimneys and parapets
- Moisture around outlets and upstands
- Areas losing heat at the eaves and junctions
Thermal roof survey in The Chart
A thermal survey isn’t a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. If a finding can’t be confirmed, the report suggests a next step. If you’ve noticed water getting in at parapets and stacks and missing or slipped insulation, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as The Chart, older roofs are often steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you cannot get from ground level. Weather and airspace are checked ahead of the visit. 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.

What a thermal roof survey looks like in The Chart
Historic houses like Chartwell, about 1.9 miles east, show how far back building in the area around The Chart goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
For site and facilities teams at buildings like Limpsfield CofE Infant School, a view from above covers a wide roof far faster than walking it.
The Chart is about 6 miles south-east of Caterham, in Surrey. The Chart is part of the area we cover and the surrounding area across London and South East England. The Chart is one of the places in Surrey where we work. We also survey roofs in Crawley.
All of RH8 is within our area for thermal roof surveys. Whether your property is on Stoneleigh Road, St Andrews Way and Ridlands Lane or a nearby road, we can survey it. We also cover Pains-Hill (1 mile west), Moorhouse Bank (1 mile north-east), Goodley Stock (1 mile east), Limpsfield (1 mile north-west) and Crockham Hill (1 mile south-east). Further out, we also cover Epsom (15 miles north-west), Horley (10 miles south-west), Redhill (9 miles west), Ewell (15 miles north-west), Reigate (10 miles west) and Caterham (6 miles north-west).
Near you in The Chart

Not far away are Botley Hill and Bay Pond.
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Why it is worth a survey now in The Chart
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. Older cottages and farmhouses around The Chart can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your roof before booking.

Read what a roof survey costs and what we found on two real jobs.
How the survey works
The visit has one job: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Cottages and farmhouses around The Chart often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photographs and our recommendations.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Keep pets inside or away from the areas we are looking at
- Tell us where we can park nearby

Advice
Roof by roof
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. The report explains what the images can tell you and what they cannot.
The Chart: your questions answered
Do you carry out roof surveys in The Chart?
Yes. We survey roofs across London and South East England, and The Chart is part of that. You can ring 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
Does a conservation area affect roof work in The Chart?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
Does someone need to be in?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access.
Does thermal imaging work on slate and tile 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.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
When to book a survey in The Chart
Not every roof problem shows on the surface. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. A thermal camera adds another way of finding them.
These are some of the problems a survey can pick up:
- Possible trapped moisture under a flat roof covering
- Areas losing heat at the eaves and junctions
- Wet areas near outlets and upstands
- Damp around chimneys and parapets
Take an older house close to St Andrew's: older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Before you book any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What they won’t be able to tell you
- Whether they hold professional indemnity and public liability insurance
- How long the report takes to arrive
What a thermal roof survey doesn’t cover
It is a careful look at the roof, not the whole story. The main limits are:
- A structural engineer’s assessment
- A formal energy assessment
- Reliable images in rain, strong wind or on a wet roof surface
