How a thermal roof survey works in Thorney Island
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. If you are worried about patches of heat loss across the roof and gaps in loft insulation, a survey will tell you what’s going on, whatever the roof.
Some older homes in villages like Thorney Island are listed or in a conservation area. A look from above or with a thermal imager does not touch 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 it applies, structural analysis and an in-person consultation.

Why get it checked now?
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, rather than more guesswork. Where a roof is exposed, as many are in small places like Thorney Island, driving rain gets into any weakness, and damp in older walls is slow to dry out.
A Basic Survey starts from £150, including VAT. Standard is from £250 and Premium from £400. We confirm the price for your roof before you book.

What we cannot see
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Clear results when the conditions on the day are poor
- A structural engineer’s assessment
- Proving moisture from the images alone

For landlords and managing agents
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
Should I look at the roof myself first?
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.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
The survey, step by step
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Rural addresses near Thorney Island can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
Getting ready for the survey
- Jot down any questions you want answered
- Move anything stored under the loft hatch
- Mention any parking restrictions on your street
Booking a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.

Thermal roof surveys around Thorney Island
The coast is about 1 mile or less from Thorney Island, and coastal wind can be strong. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
If you look after a building such as Thorney Island Community Primary School, big roofs are where aerial photos and thermal images show the most at once. For an older house near a landmark such as The Parish Church of St Nicholas, older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

What we’re asked to look at in Thorney Island
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
A survey can pick up problems such as:
- Areas of a flat roof that may hold water
- Leaks that are hard to trace
- Damp patches with no obvious cause
- Heat escaping through the roof

Before booking any roof surveyor
- Are they insured for the work?
- Whether the loft is part of the inspection
- Their drone registration, if they fly one
- How they’ll see the roof: from ground level, the loft, the roof or by drone
Thorney Island questions
Is Thorney Island within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Do you cover Thorney Island?
We do. The survey and report are the same in Thorney Island as anywhere else.
How long is the visit?
Most surveys take about one to two hours at most homes; commercial roofs usually need 3–4 hours. The report follows by email.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Is thermal imaging good for finding leaks?
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 because the camera can’t confirm water on its own.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
