Thermal imaging roof survey in Sunbury-on-Thames, Surrey
Thermal roof surveys across Sunbury-on-Thames, with over 20 years’ experience behind it. You get a clear report with photographs.
- Damp around roof outlets and upstands
- Cold spots on ceilings under the roof
- Stains that keep coming back
Should I look at the roof myself first?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
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.
Thermal roof survey in Sunbury-on-Thames
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That’s why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. Where something can’t be confirmed, we say what would help next. If you’ve noticed damp patches with no obvious cause and cold areas below the roof, we can find out what’s behind it.
In older houses around Sunbury-on-Thames, loft insulation can be thin, patchy or missing in places. A thermal camera shows those cold and warm patches, and some of them can point to moisture. It shows temperature, so anything that looks like moisture is checked with a meter. Results depend on conditions, so the timing of the visit matters.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Airspace, weather and Sunbury-on-Thames roofs
In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Sunbury-on-Thames is about 2 miles from the edge of the flight restriction zone around Heathrow Airport. Where the drone is part of the survey, the exact boundary is checked for the address first.
Hampton Court Palace lies about 3.5 miles east, so building around Sunbury-on-Thames goes back a long way. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition. Anyone responsible for a site like St Ignatius RC Primary School will know that a drone or thermal camera can show a large roof in a single visit. Take an older house close to St Saviour: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

What we can’t see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Proving moisture from the images alone
- Hidden layers that need to be opened up to check
- A structural engineer’s assessment
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before you book. The full list of what we check.
What we look at
- Ceilings below the roof
- Insulated roof spaces
- Loft conversions
- Pitched roof slopes
- Flat roofs
- Commercial roofs
How it works
Every roof is different; as a rough guide, the survey takes between one and two hours at most homes, while a commercial roof takes nearer three to four hours. If you have questions on the day, just ask. For a home in Sunbury-on-Thames, the main things we need are a way into the loft, a route to the back garden and somewhere to park. Someone needs to let us in, so let us know who that will be.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- Have any paperwork from past roof work to hand
- Buyers: confirm access with the estate agent or seller
- Have keys ready for side gates, garages or roof access doors
Book a survey
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. For any other survey, just phone 07833 053749 or email us when you’re ready.
Related advice
Leave it or get it looked at?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Around Sunbury-on-Thames, water from a roof defect often goes unseen for a while, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
To find out what your survey will cost, phone 07833 053749 or use the contact form and let us know about the roof. The price is agreed before a date is set.

FAQs for Sunbury-on-Thames
Are there drone restrictions around Sunbury-on-Thames?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around Heathrow Airport comes within about 2 miles of Sunbury-on-Thames. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. A small drone can’t fly safely in high wind or heavy rain.
Is Sunbury-on-Thames in the area you cover?
Yes, Sunbury-on-Thames is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or send us an email and let us know about the property, and we will talk through which survey suits.
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, and moisture readings are used to check it.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. The survey is not an energy rating or a heat loss calculation, but the images show where improvements may help.
Can you use a thermal camera on a sloping roof?
It can be useful, though pitched roofs are typically harder to read. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there is safe access.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Practical tips
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Use the report as a baseline for later checks
- Check from ground level or a window, never by climbing
- Check the loft can be reached safely
- Note where damp appears and after what weather
Where a pattern can’t be confirmed, the report says what could help, such as electronic leak detection or opening up a small area.
Consider a repeat survey after major work on the roof, when the conditions are suitable.
Prices for thermal roof surveys in Sunbury-on-Thames
All our prices include VAT. What changes the price is:
- The use of thermal imaging or a drone
- Height and safe access
- The size of the roof
- House, block, shop or office
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
Booking your survey
To price your survey accurately, we will ask about:
- The kind of building and roof involved
- Whether there is a loft hatch, a shared roof or tricky access
- Photos of the roof, taken safely from the ground or a window
- What’s prompted the survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.
