How a thermal roof survey works in Marehill
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It is important to know that the camera shows temperature, not water, so we check what it shows with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’ve noticed gaps in loft insulation and damp around roof outlets and upstands, a survey will tell you what’s going on, on loft conversions, flat roofs and ceilings below the roof alike.
In a small place like Marehill, open ground can mean strong wind. 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. A change in the forecast can mean moving the visit to another day.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Marehill questions
How do I find out if my home in Marehill is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Is Marehill within the area you cover?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we will agree the details as you book.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Can a thermal camera see water?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
What does the report include?
You get our findings in writing, part by part, with photos. Points are put by urgency where it matters.
When to book a survey in Marehill
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
Signs worth acting on include:
- Damp where roofs meet walls and chimneys
- Cold spots on ceilings under the roof
- Water that travels before it shows
- Possible trapped moisture under a flat roof covering
Take a building like St Mary's Church of England Primary School: thermal images can show where wet insulation sits under a big flat roof.
Questions to ask before you book
- What experience they bring
- Whether they hold professional indemnity and public liability insurance
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- When you will get the report

Prices for thermal roof surveys in Marehill

- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, inc. VAT. We’ll tell you which package suits the questions you have.

What we do, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit typically takes about 1–2 hours at a typical home, rising to roughly 3–4 hours on a commercial building. Somewhere as small as Marehill, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We check the roof from the ground, from windows and from the roof itself where it is safe.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- Tell us about parking before the day
- For a flat or shared roof, check access with the freeholder or managing agent
- Have keys ready for side gates, garages or roof access doors
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or send us an email.
Related advice
What happens if roof problems are left?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. That helps you and your roofer decide what really needs replacing. For older village homes like those around Marehill, the right replacement materials aren’t always easy to find quickly. That’s one more reason to find defects before they become urgent.
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. You will know the price for your roof before booking.
