Thermal Roof Survey in Fernhurst
Thermal imaging to find moisture and heat loss patterns in a roof around Fernhurst, with a written report you can act on. Book a weekday or weekend visit.
- Water getting in at parapets and stacks
- Stains that keep coming back
- Cold spots on ceilings under the roof
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
How a thermal roof survey works in Fernhurst
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. If you’ve noticed thin or uneven insulation in the roof and wet insulation beneath the membrane, we can find out what’s behind it, on flat roofs, ceilings below the roof and commercial roofs alike.
In a village or hamlet like Fernhurst, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what can’t be reached safely. Weather and airspace are looked at ahead of the visit. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Why get it checked now?
For buyers, a thermal survey adds detail that a visual inspection cannot give. Finding hidden moisture before exchange gives you facts to raise with the seller. For an older or listed building in a place like Fernhurst, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Why book with us
- Over 5,000 surveys carried out
- An independent view of the roof
- Packages from £150, inc. VAT
- CAA-registered drone operator (Flyer ID and Operator ID)

Useful tips for Fernhurst property owners
Here are a few things we’d tell any owner, before and after a survey:
- Keep the heating on as usual before a heat loss survey
- Move stored items away from the loft hatch
- Keep a record of when stains appear
- Use the report as a baseline for later checks
Buyers can use the findings when talking to the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
What happens on the day
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. The whole visit normally takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. For a village or hamlet like Fernhurst, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from the ground, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Show us where any leaks or stains appear
- Unlock side gates and any roof access doors
- Mention any parking restrictions on your street

Flying and imaging in Fernhurst
With Cowdray House about 4.3 miles south, Fernhurst sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Steep or complicated roofs are frequently hard to see from ground level, which is where close-up aerial shots and thermal images help.
The streets around a church such as The Parish Church of St Margaret are frequently among the oldest in a place, and if you own one of the older houses nearby, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help. Take a building like Fernhurst Primary School: big roofs are where aerial photos and thermal images show the most at once.

What we look for on each type of roof
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We check cracks by eye and use the images to see whether there’s a pattern around them.
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. Thermal imaging can help show damp patterns around them.
Fernhurst: your questions answered
Do you cover Fernhurst?
Yes, Fernhurst is within the area we cover. We work right across London and South East England. You can call 07833 053749 or send us an email with the address and some details, and we’ll talk through which survey suits.
Do you cover smaller places like Fernhurst?
Yes. Fernhurst is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Is this a RICS 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 happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will I get photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
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 and suggest a specialist asbestos surveyor checks them before any work.
What conditions are best for thermal imaging?
The weather makes a real difference. 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 discuss the forecast when booking.
When you need someone else
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- An energy rating for the building
- Readings unaffected by sun, shade or reflections
- Proving moisture from the images alone
If in doubt, ring 07833 053749 or drop us an email and we will point you to the right survey. What our survey covers.
