Thermal imaging roof survey in Chorleywood West, Hertfordshire
Thermal imaging to find moisture and heat loss patterns in a roof in Chorleywood West, carried out by an experienced roof surveyor. Every survey comes with a written report and photographs.
- Heat escaping through the roof
- Water getting in at parapets and stacks
- Damp around roof outlets and upstands
How we price thermal roof surveys
Several things affect the price of a survey:
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether you choose the Basic, Standard or Premium Survey
- Commercial roofs and larger buildings
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all with VAT included. What your roof costs depends on its size, access and what you want to find out.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- Anything about access we should know
- The type of building and roof, such as pitched or flat
- What’s prompted the survey
- Where the property is, with the postcode
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.
Thermal roof surveys for homes and businesses in Chorleywood West
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. The report shows the images and explains what they may mean. We don’t give energy ratings or heat loss calculations. Typical surveys look at cold areas below the roof and water that travels before it shows, on insulated roof spaces, commercial roofs and loft conversions.
Older buildings in small places like Chorleywood West may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
We keep jargon out of it: where something needs attention, it says so plainly.

What a thermal roof survey doesn’t cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Seeing water directly, as the camera shows temperature, not moisture
- A formal energy assessment
- What’s inside walls or under coverings, without opening up
If in doubt, ring 07833 053749 or email us and we will recommend the right survey before you book. What a survey covers and does not.
What we check
- Commercial roofs
- Pitched roof slopes
- Insulated roof spaces
- Loft conversions
- Flat roofs
- Ceilings below the roof
Thermal roof surveys in Chorleywood West: local notes
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. Steep or complicated roofs are frequently hard to see from the ground, which is where aerial photos and thermal images help. About 2.8 miles north-west lies Chenies Manor House, a reminder of how long the area around Chorleywood West has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Arnett Hills Junior Mixed and Infant School will know that big roofs are where photos from the air and thermal images show the most at once. If you run a business near Charter Place, big, flat commercial roofs are where aerial photos and thermal images help most.

Roof by roof
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Shiny surfaces can reflect heat, so we take care reading the images.
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. We check those patches with moisture readings.
Common questions in Chorleywood West
Do you cover Chorleywood West?
Yes. We cover the whole of London and South East England, and Chorleywood West is part of that. You can call 07833 053749 or drop us an email with the address and some details.
Will you come out to Chorleywood West?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Can you survey at the weekend?
We carry out surveys seven days a week. To arrange a date, ring 07833 053749 or use the contact form.
What can thermal imaging tell me about my roof?
The images show how warm or cool each part of the surface is. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. It works best after a sunny day, with a dry roof surface and little wind. Rain and strong wind can make the images less clear, so we talk through the forecast when you book.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What we do, step by step
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey typically takes between one and two hours on an ordinary house, and about three to four hours for a commercial roof. For a village or hamlet like Chorleywood West, 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 is safe access and from the roof where it’s safe.
- You tell us about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- If it isn’t your property yet, arrange access through the agent
- If the roof is shared, arrange access with whoever manages the building
- Keep pets out of the way during the survey
How to book
Photos help, if you have them. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To send them or to book, ring 07833 053749 or send us an email.
Advice
Common roof problems in Chorleywood West
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Problems we come across frequently include:
- Heat escaping through the roof
- Ceilings that feel colder in places
- Wet insulation beneath the membrane
- Water that travels before it shows
Take an older house close to Church of St Peter: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.
What to check before booking
- Will the report include photos?
- Are they insured for the work?
- Whether VAT is added on top
- Whether any drone flown is registered with the CAA
Leave it or get it looked at?
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Outbuildings and barns around Chorleywood West are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
