Thermal imaging roof survey in Great Thorness, Isle of Wight
Thermal imaging to find moisture and heat loss patterns in a roof for Great Thorness, from an experienced roof surveyor. Every survey comes with a written report and photographs.
- Wet insulation beneath the membrane
- Water getting in at parapets and stacks
- Damp around roof outlets and upstands
About our thermal roof survey in Great Thorness
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging frequently helps most. Patterns can suggest where water is trapped under the covering. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we also look from the loft where we can reach it safely. If you’ve noticed wet areas near outlets and upstands and thin or uneven insulation in the roof, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Great Thorness may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof, 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.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What a thermal roof survey looks like in Great Thorness
Great Thorness is within about 1 mile of the coast, and wind off the sea can be strong. Clear thermal results need a dry roof and little wind after a sunny day, so the date depends on the forecast. Thatch survives on some older Isle of Wight buildings, and sea air and wind reach every part of the island. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
Around Great Thorness, as everywhere, small roof faults are simplest to sort before they let water in.
Great Thorness is about 3 miles south-west of Cowes, in the Isle of Wight. Great Thorness is one of many places we visit across the Isle of Wight, for homes and businesses alike. Across the Isle of Wight, we cover Great Thorness. Our Southampton page covers surveys nearby.

DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
How we price thermal roof surveys
What a survey costs depends on the time and equipment it needs. That comes down to:
- Features like valleys, chimneys, dormers and parapets
- How many separate roofs there are, such as extensions, dormers and garages
- House, block, shop or office
- Whether thermal imaging or a drone is needed
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we can help you choose.
Helping us price your survey
If you can, have these to hand when you get in touch:
- Any stains, drips or damp patches you’ve seen indoors
- The reason for the survey, such as buying, a leak or storm damage
- What kind of property and roof it is
- The address and postcode of the property
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.
What we look for on each type of roof
Loft insulation
In the roof space, the camera can pick up gaps and thin areas of insulation. We inspect the loft where it can be reached safely.
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.
What we are asked to look at in Great Thorness
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. A thermal survey, checked with moisture readings, can give a much clearer picture.
Most people get in touch after spotting one of these:
- Wet areas near outlets and upstands
- Areas of a flat roof that may hold water
- Areas losing heat at the eaves and junctions
- Missing or slipped insulation
With Swainston Manor about 3 miles south, the area around Great Thorness has a long history. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition.

FAQs for Great Thorness
Is Great Thorness within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Is my home in Great Thorness listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
How long does the survey take?
Time on site depends on the roof; most visits take an hour or two at most homes, or half a day or so for a commercial building. The written report follows by email.
Are you insured?
We hold professional indemnity and public liability insurance.
Can you use a thermal camera on a sloping roof?
It can be useful, though pitched roofs are usually harder to read. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it is safe.
Is thermal imaging good for finding leaks?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It’s used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.
The survey, step by step
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Around Great Thorness, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We go through the roof, the problem and the weather expected on the day.
- 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.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Find any records of previous roof work
- Clear the way to the loft hatch

Why it’s worth a survey now in Great Thorness
Wet insulation under a flat roof does not dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. For an older or listed building in a place like Great Thorness, 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 the price reflects that. The price is confirmed before booking.
