Clothall Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof for Clothall, from an experienced roof surveyor. You get a clear written report with photographs.
- Heat escaping through the roof
- Moisture around outlets and upstands
- Damp where roofs meet walls and chimneys
About our thermal roof survey in Clothall
A thermal camera can help when the cause of damp isn’t obvious. Leaks frequently run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. The images are used alongside a visual inspection and moisture readings, so the findings do not rely on the camera alone. We survey insulated roof spaces, flat roofs and ceilings below the roof, and the problems we’re asked to look at most are water that travels before it shows and damp around chimneys and parapets.
Somewhere as small as Clothall, older roofs are frequently steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Your questions about thermal roof surveys in Clothall
Do you carry out roof surveys in Clothall?
We do. The survey and report are the same in Clothall as anywhere else.
Is Clothall within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Will the camera show exactly where the water is?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
What’s the best way to book?
The quickest way is to phone 07833 053749 or use the contact form. Give us the address and some details about the roof. We survey on weekdays, Saturdays and Sundays.
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.
What happens next?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Roof by roof
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We allow for reflections and confirm findings with moisture readings.
Loft insulation
Heat loss shows most clearly when it is warm inside and colder outside. We explain in the report how the conditions on the day affected what we saw.
What we do, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Older roofs in small places like Clothall can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Before the survey
- If you are buying, check with the agent that we can get in
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or email us.

Thermal roof surveys in Clothall: local notes
If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
For site and facilities teams at buildings such as Weston Primary School, thermal images can show where wet insulation sits under a big flat roof.
Clothall is about 3 miles east of Letchworth, in Hertfordshire. Anywhere in Clothall, we can come and survey your property. Our Hertfordshire coverage includes Clothall and the places around it. For surveys nearby, see our Milton Keynes page.

Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Structural calculations, which need a structural engineer
- The condition of timbers we can’t see
- An energy rating for the building

What else we do in Clothall
Do you need a thermal roof survey in Clothall?
Some buyers want extra detail before they commit to a purchase. The Premium Survey brings thermal imaging and a drone inspection where applicable, with a report the same day, which suits a purchase that is moving quickly.
A survey can pick up problems such as:
- Damp where roofs meet walls and chimneys
- Areas losing heat at the eaves and junctions
- Water that travels before it shows
- Damp patches with no obvious cause
Take an older house close to Church of St Mary: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
What to check before booking
- Will the report include photos?
- Whether VAT is added on top
- What insurance they carry
- What they won’t be able to tell you
What happens if roof problems are left?
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. That helps you and your roofer decide what really needs replacing. For older village homes like those around Clothall, the right replacement materials aren’t always easy to find quickly. That is one more reason to find defects before they become urgent.
For a price for your roof in Clothall, ring 07833 053749 or use the contact form and let us know about the roof. We will confirm the figure before booking.

What affects the cost of thermal roof surveys
When we price a survey, we consider:
- The type of building, from a house to a block or an office
- Basic, Standard or Premium
- Whether thermal imaging or a drone is needed
- Building height and the viewpoints available
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.
Getting in touch
You don’t need to know any roofing terms. Just let us know:
- The reason for the survey, such as buying, a leak or storm damage
- Any photos you have, taken from the ground or a window
- How the loft is reached, if there is one
- The address and postcode of the property
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
