Your questions about thermal roof surveys in Charlwood
Is Charlwood within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Does a conservation area affect roof work in Charlwood?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
How does a thermal imaging roof survey work?
The camera records how the surface temperature varies. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
Does the weather affect a thermal survey?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Which days do you carry out surveys?
Surveys run seven days a week. To arrange a date, call 07833 053749 or email us.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
About our thermal roof survey in Charlwood
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera does not see water itself, so we check what it shows with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We survey commercial roofs, ceilings below the roof and loft conversions, and people most often book us about stains that keep coming back and gaps in loft insulation.
Somewhere as small as Charlwood, older roofs are often steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you can’t get from ground level. Weather and airspace are looked at before the visit, and the journey is planned in advance. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
Findings are set out part by part, from the main slopes down to the gutters and outlets. You’ll see the good as well as the bad.

Signs you need a thermal roof survey 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.
A survey makes sense if you’ve noticed:
- Cold spots on ceilings under the roof
- Gaps in loft insulation
- Wet insulation beneath the membrane
- Damp around roof outlets and upstands
If your home is one of the older ones in the streets near Monkwood Mission Church, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view by drone or thermal camera helps.
What to check before booking
- What follow-up you get after the report
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Is VAT included in the price?
- Whether the loft is part of the inspection
Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Keep outlets and gutters clear to stop water sitting
- Do not climb onto the roof to look for leaks yourself
- Note where damp appears and after what weather
- Remember the conditions on the day affect the results
Buyers can use the findings when talking to the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
The survey, step by step
On the day, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can be seen safely. The survey normally takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere as small as Charlwood, access is frequently 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.
- 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.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Clear the way to the loft hatch
- Jot down any questions you want answered
- Let us know where we can park nearby
How to book
Prices start from £400, including VAT. The exact figure depends on the roof and the package, and you can call 07833 053749 or drop us an email to find out.

What a thermal roof survey looks like in Charlwood
The wider area around Charlwood has a long history of building, with Bentworth Hall about 4.8 miles north. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.

How the survey changes by roof type
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. We use the camera and moisture readings to help follow it.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below frequently show. Reflections from shiny surfaces can affect readings, which we allow for.
