Thermal imaging roof survey in Charlton, Hertfordshire
Thermal roof surveys in Charlton and the rest of Hertfordshire. Surveys run on weekdays, Saturdays and Sundays.
- Patches of heat loss across the roof
- Thin or uneven insulation in the roof

Thermal roof surveys for homes and businesses in Charlton
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. Our report points out what the images suggest and where to look more closely. We don’t give energy ratings or heat loss calculations. We survey ceilings below the roof, insulated roof spaces and flat roofs, and the problems we’re asked to look at most are areas of a flat roof that may hold water and missing or slipped insulation.
Villages like Charlton often stand in open country, where wind can be strong. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
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.

Useful tips for Charlton property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where damp appears and after what weather
- Don’t switch the heating off before the visit
- Check outlets after heavy rain
- Leave the roof to people with safe access
After the visit, we put the thermal images, photographs and moisture readings into one report. We explain what each image may mean, alongside what we recommend. With a Premium Survey, you get the report the same day.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
How the survey changes by roof type
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. We explain in the report how the conditions on the day affected what we saw.

Your questions about thermal roof surveys in Charlton
Will you come out to Charlton?
Yes, Charlton is on our map. A small place gets exactly the same survey as a big one.
Is Charlton in the area you cover?
Yes, Charlton is one of the places we work. The survey and report are the same in Charlton as anywhere else.
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 cannot be pinned down, the report suggests a next step, such as electronic leak detection.
Is thermal imaging useful on pitched 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 back them up with a visual inspection and moisture readings.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when you book.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Does the report include photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
What a thermal roof survey looks like in Charlton
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there.
If you look after a building such as Highbury Infant School and Nursery, a view from above covers a wide roof far faster than walking it. For an older house near a landmark such as St Mary's Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Charlton is about 1 mile south-west of Hitchin, in Hertfordshire. We carry out thermal roof surveys in Charlton for houses, flats, blocks and commercial buildings. Charlton is one of the towns and villages in Hertfordshire we cover. You can also see our page for Milton Keynes.

How it works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. For a village or hamlet like Charlton, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s 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.
Preparing for the visit
- Agree roof access with the managing agent if it’s shared
- If you are buying, let the agent know when we are coming
- Find any records of previous roof work

Surveys for landlords and agents in Charlton
Landlords, agents and building managers in Charlton and across Hertfordshire can book any of our surveys. For a price for a let property or a block, call 07833 053749 or use the contact form.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
What you can safely check yourself
What you cannot do safely is get up close. Roofs are fragile and slippery. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
What a survey costs
Prices always include VAT. The things that change the price are:
- The height of the building and how the roof can be seen safely
- The type of building, from a house to a block or an office
- Extra roofs, like extensions, dormers or garages
- If the survey needs thermal imaging or a drone
Thermal roof survey starts from £400, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.
Getting in touch
A little information up front helps. Please include:
- Where the property is, with the postcode
- The type of building and roof, like pitched or flat
- Your timetable, like an exchange date
- Any photos you have, taken from the ground or a window
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, phone 07833 053749 or send us an email.
