Thermal roof survey in Gosmore
A thermal survey is not a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That is why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. Where something cannot be confirmed, we say what would help next. If you’re worried about water that travels before it shows and cold spots on ceilings under the roof, we can find out what’s behind it.
Villages like Gosmore often stand in open country, where wind can be strong. A small drone cannot fly safely in high wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The report records the roof as we found it on the day. It’s useful straight away, and a good reference for later, such as when you want to compare after future work.

What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
How it works
The visit has one job: to look at the roof as closely as is safe and record what we find. Notes and photos go into the written report. It normally takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older roofs in small places like Gosmore can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there is safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- Jot down any questions you want answered
- Let us know where we can park nearby
Arrange a survey
Booking is simple: just phone 07833 053749 or email us, let us know about the property and we will point you to the right survey. We confirm the price before anything is booked.

When you need someone else
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Reliable images in rain, strong wind or on a wet roof surface
- The condition of timbers we can’t see
- Seeing water directly, as the camera shows temperature, not moisture
If you’re not sure which survey you need, ring 07833 053749 or drop us an email and we’ll give you a straight answer before booking. The full list of what we check.
What we check
- Flat roofs
- Ceilings below the roof
- Commercial roofs
- Pitched roof slopes
- Insulated roof spaces
- Loft conversions
What we look for on each type of roof
Parapets, valleys and junctions
Problems where roof slopes and walls meet are often hidden. We combine a close visual check with the thermal images.
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences often show through. We confirm any patterns with moisture readings.
What affects the price in Gosmore
What a survey costs depends on the time and equipment it needs. The main factors are:
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
- Whether you choose the Basic, Standard or Premium Survey
Prices start from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.
Booking your survey
A little information up front helps. It helps to include:
- Any photos you have, taken from the ground or a window
- Access details, such as a loft hatch or a shared roof
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
Every survey is priced before it’s booked, so you know the cost up front. Our price is from £400, including VAT. To book, phone 07833 053749 or drop us an email.

Gosmore: your questions answered
Do you carry out roof surveys in Gosmore?
Yes, Gosmore is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or send us an email and let us know about the property, and we will talk through which survey suits.
Will you come out to Gosmore?
Yes, Gosmore is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. We will recommend an engineer if we see signs that call for one.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
How long will you be at the property?
That depends on the size and shape of the roof, but most surveys take about one to two hours for most homes, plus time to check any thermal findings with moisture readings. The report is sent afterwards by email.
Can a thermal survey trace a roof leak?
It often helps show where to look. Patterns can suggest where trapped water has spread. It’s used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
Will you go up on the roof?
Only if it is safe. We inspect what can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Do you need a thermal roof survey in Gosmore?
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.
These are some of the problems a survey can pick up:
- Gaps in loft insulation
- Cold areas below the roof
- Moisture around outlets and upstands
- Leaks far from where the stain appears
If your house is among the older ones in the streets near Church of St Ippolyts (church of England), older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

Drones, thermal imaging and Gosmore roofs
Within a mile and a half or so of Gosmore there are several hotels. If you look after one, a large roof can be surveyed without guests having anyone working above them. 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. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
For hotels and guest houses around Gosmore, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. Knebworth House lies about 4.7 miles south-east, so building around Gosmore goes back a long way. Older roofs nearby can be steep and hard to see from the ground, and a survey from above or with a thermal imager does not touch the roof itself.
