Thermal imaging roof survey in Windsor, Windsor and Maidenhead
Not sure what state the roof is in? We carry out thermal roof surveys in Windsor and across Windsor and Maidenhead.
- Water that travels before it shows
- Damp around chimneys and parapets
- Possible trapped moisture under a flat roof covering
Why get it checked now?
Buyers get extra information from thermal images that the eye can miss. Hidden problems found before exchange can be raised with the seller or agent. Extensions and dormers on homes around Windsor often hide the first signs of trouble at their joints with the main roof. Left for a few seasons, it can spoil plaster, skirting and flooring inside.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
Why book with us
- Packages from £150, with VAT included
- Customer satisfaction of 98%
- Drone and thermal imaging surveys available
- Two decades and more of roof surveys

Thermal roof survey in Windsor
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. The camera does not see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’re worried about areas of a flat roof that may hold water and damp around chimneys and parapets, we can find out what’s behind it, whatever the roof.
Before any drone flight in a town like Windsor, the airspace is checked on the Drone Safety Map, including zones around airports and prisons. Our drone weighs under 250g, and we are a CAA-registered drone operator (Flyer ID and Operator ID). Neighbours’ privacy is part of planning every flight. In the open category, flights stay under 120 m (400 ft) with the drone in sight.
Where we can’t see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t.

Questions from Windsor
How do I find out if my home in Windsor is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How should I get ready for a visit in Windsor?
The main thing is access, inside and out, plus somewhere to park in Windsor. Tell us about known leaks or past repairs as well.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
Can a thermal survey trace a roof leak?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings because the camera can’t confirm water on its own.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
What affects the cost of thermal roof surveys
All our prices include VAT. What changes the price is:
- Commercial roofs and larger buildings
- Features like valleys, chimneys, dormers and parapets
- If the survey needs thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
To find out what your survey will cost, ring 07833 053749 or drop us an email and let us know about the roof. We’ll confirm the figure before booking.
What we need to know
A little information up front helps. Please include:
- Whether there is a loft hatch, a shared roof or tricky access
- Any photos you have, taken from ground level or a window
- Where any leaks, stains or damp patches show inside
- What made you get in touch
To arrange a survey, ring 07833 053749 or email us with the address and what you’d like to know about the roof. We will confirm the price before booking.
Useful tips for Windsor property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Leave the roof to people with safe access
- Heat the home normally on the days before
- Tell us where and when you’ve seen damp or stains
- Check outlets after heavy rain
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it’s easy to find each area on the roof.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.
Roof by roof
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. The camera can help show where to look.
What a thermal roof survey does not cover
Every survey has limits, and it is better to know them up front. Bear these in mind:
- Confirming water without moisture readings
- What’s inside walls or under coverings, without opening up
- Insulation values or heat loss calculations
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer before booking. What our survey covers.
What we look at
- Loft conversions
- Insulated roof spaces
- Flat roofs
- Ceilings below the roof

What else we do in Windsor
How the survey works
The aim of the visit is simple: to see as much of the roof as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It normally takes between one and two hours for most houses, though large, tall or awkward roofs take more time. For a visit in Windsor, we need access to the loft, any rooms with leaks or stains, and the outside of the building. Mention gates, side passages and anything at the back. Visits can be on weekdays, Saturdays or Sundays.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- 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.
- You get a report with thermal images, photographs and our recommendations.
How to prepare
- Keep pets inside or away from the areas we are looking at
- Gather any invoices or paperwork from past roof work
- Show us where any leaks or stains appear
Getting a price
Thermal roof survey starts from £400, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or use the contact form with the details.
Advice
Flying and imaging in Windsor
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Steep or complicated roofs are frequently hard to see from ground level, which is where close-up aerial shots and thermal images help. The wider area around Windsor has a long history of building, with St Leonard's Hill about 1 mile south-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Anyone responsible for a site like St Edward's Catholic First School will know that big roofs are where photos from the air and thermal images show the most at once. For hotels and guest houses around Windsor, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. For an older house near a landmark such as All Saints Church, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
