Thermal Roof Survey in Coleman Green
Independent thermal roof surveys in Coleman Green. We’ve completed more than 5,000 surveys across London and the South East.
- Ceilings that feel colder in places
- Heat escaping through the roof
- Water getting in at parapets and stacks
Roof by roof
Loft insulation
In the loft space, the camera can pick up gaps and thin areas of insulation. We inspect the loft where it can be reached safely.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and cannot be read from them.
Thermal roof survey in Coleman Green
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. We combine the images with a visual inspection and moisture readings, so the findings do not rely on the camera alone. We are often asked to look into cold spots on ceilings under the roof and moisture around outlets and upstands, across ceilings below the roof, loft conversions and flat roofs.
In a village or hamlet like Coleman Green, 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 the ground. Weather and airspace are looked at ahead of the visit, and the journey is planned in advance. Steep slopes and tall chimney stacks are where a close-up view adds the most.
After the visit, you get a written report with photographs, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Why act early in Coleman Green
Wet insulation under a flat roof does not dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Where a roof is exposed, as many are in small places like Coleman Green, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Every price we give includes VAT, and the written report is part of the package. Prices start from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Drones, thermal imaging and Coleman Green roofs
If your survey includes the drone, the flight is checked against the Drone Safety Map first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
If you run a business near Howard Centre, thermal images can show trapped moisture across a wide commercial roof. Take a building like Beech Hyde Primary School and Nursery: big roofs are where aerial photos and thermal images show the most at once.

Do you need a thermal roof survey in Coleman Green?
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Common reasons to book include:
- Areas of a flat roof that may hold water
- Damp where roofs meet walls and chimneys
- Wet areas near outlets and upstands
- Patches of heat loss across the roof
Shaw's Corner, about 2.5 miles north, is one of the historic houses in the wider area around Coleman Green. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.
What to check before booking

Landlord and commercial surveys in Coleman Green
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we’ll plan the visit with that in mind.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
What affects the cost of thermal roof surveys
Our packages start from £150, with VAT included. What you pay for your roof depends on:
- The size of the roof
- The use of thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- How tall the building is and how easy the roof is to see
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Helping us price your survey
A few details help us suggest the right survey and price. When you contact us, it is useful to mention:
- Any stains, drips or damp patches you’ve seen indoors
- The address and postcode of the property
- Any photos you have, taken from the ground or a window
- The style of property, from a terrace to a block
To book a survey, phone 07833 053749 or send us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
Your questions about thermal roof surveys in Coleman Green
Do you carry out roof surveys in Coleman Green?
Yes, Coleman Green is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or email us and let us know about the property.
How do I find out if my home in Coleman Green is listed?
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. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
Will you photograph what you find?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
Is this an asbestos survey?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
How does a thermal imaging roof survey work?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours for most houses, though large, tall or awkward roofs take more time. You’re welcome to ask questions while we are there. Older rural homes like those around Coleman Green can have a main roof, lower lean-to roofs and outbuildings all joined together. 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 carry out a visual inspection of the roof from wherever it can safely be seen.
- A thermal camera records how the surface temperature varies across the roof.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- Mention any parking restrictions on your street
- If you’re buying, check with the agent that we can get in
- Jot down any questions you want answered
How to book
Photos help, if you have them. Pictures from the ground or a window are fine. To send them or to book, call 07833 053749 or send us an email.
