How a thermal roof survey works in Old Windsor
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. 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 combine the camera with an inspection from the loft where there’s safe access. Common reasons to book are missing or slipped insulation and leaks that are hard to trace, on ceilings below the roof, loft conversions and pitched roof slopes.
In smaller places like Old Windsor, many homes are bungalows and houses with roofs you can partly see from the ground. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. Both depend on the weather on the day. Even so, a close-up image frequently shows wear on ridges and flashings that a view from ground level misses.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

What happens if roof problems are left?
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding the wet areas sooner keeps the work smaller. Homes in smaller places like Old Windsor can face more weather, so a loose ridge or verge soon lets rain in. Each storm lifts it a little further.
Prices quoted always include VAT, and the written report is part of the package. Thermal roof survey starts from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Old Windsor questions
Is my home in Old Windsor listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Will you come out to Old Windsor?
Yes. Old Windsor is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
How long will you be at the property?
Most surveys take between one and two hours on an ordinary house, or half a day or so for a commercial building. We’ll confirm the timing when booking.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
Thermal roof surveys around Old Windsor
Old Windsor is about 1 mile from the edge of the flight restriction zone around Heathrow Airport. Where the drone is part of the survey, we check the exact boundary for the address before flying. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
Frogmore House, about 1.3 miles north-west, is one of the historic houses in the wider area around Old Windsor. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition. For site and facilities teams at buildings such as King's Court First School, big roofs are where aerial photos and thermal images show the most at once. If you live in an older home near St Luke, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from above or with a thermal imager helps.

- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.

What else we do in Old Windsor
Different roofs, different checks
Parapets, valleys and junctions
Water frequently gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, given suitable conditions on the day.
