Thermal roof surveys for homes and businesses in Charlwood
A thermal camera can help when the cause of damp isn’t obvious. Leaks often run along a roof before they appear on a ceiling, and temperature patterns can help us trace where it may have come from. The images are used alongside a visual inspection and moisture readings, so the findings don’t rely on the camera alone. If you’ve noticed water getting in at parapets and stacks and moisture around outlets and upstands, a survey will tell you what’s going on.
In a village or hamlet like Charlwood, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you cannot get from ground level. 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.
If any part of the roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

What we look for on each type of roof
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
How it works
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely. The survey typically takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. For a village or hamlet like Charlwood, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photos and our recommendations.
Before the survey
- Point out any leaks or damp patches
- If you are buying, check with the agent that we can get in
- Make sure pets are kept safely away

Advice
Why it is worth a survey now in Charlwood
Heat lost through a roof costs money every winter. The camera can point to gaps and thin areas in the insulation, so improvements can go where they’re needed. For older village homes like those around Charlwood, the right replacement materials aren’t always easy to find quickly. That’s one more reason to find defects before they become urgent.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
What you get with us
- Two decades and more of roof surveys

Questions from Charlwood
Does a conservation area affect roof work in Charlwood?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Are there drone restrictions around Charlwood?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around Gatwick Airport covers Charlwood, or comes right up to its edge. We ask the airport for permission before flying there, and only fly if it is given. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
Can you use a thermal camera on a sloping roof?
It can show heat loss and some damp, but it has more limits there. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
What conditions are best for thermal imaging?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain, wind and heavy cloud can weaken the patterns, so we talk through the forecast when you book.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
What does a thermal roof survey show?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.

What a thermal roof survey looks like in Charlwood
Charlwood is inside, or right on the edge of, the flight restriction zone around Gatwick Airport. Where the drone is part of the survey, permission from the airport is needed first, and the flight only goes ahead if it is given. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask.
A roof leak in a hotel or guest house around Charlwood means lost rooms as well as repairs, so it pays to find faults before guests do. Shop and office owners around County Mall may find that a commercial roof can be photographed from above without anyone walking on it.

Common roof problems in Charlwood
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Look out for signs like these:
- Areas of a flat roof that may hold water
- Water that travels before it shows
- Gaps in loft insulation
- Water getting in at parapets and stacks
If you live in an older home near Church of St Nicholas, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps.
Before you book any roof surveyor
- Will the report include photos?
- Their report turnaround times
- How they plan to inspect the roof safely
- What the survey won’t cover
Can I check my roof myself?
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
