Thermal imaging roof survey in Colnbrook, Slough
Thermal imaging to find moisture and heat loss patterns in a roof for Colnbrook, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Cold spots on ceilings under the roof
- Gaps in loft insulation
- Water that travels before it shows
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Thermal roof surveys for homes and businesses in Colnbrook
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. If you’ve noticed possible trapped moisture under a flat roof covering and water that travels before it shows, a survey will tell you what’s going on, whatever the roof.
Some older homes in villages like Colnbrook are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care. Check with the council before planning any work on a listed building or one in a conservation area.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Common questions in Colnbrook
Do you cover smaller places like Colnbrook?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Are there drone restrictions around Colnbrook?
It depends on the exact address and the weather on the day. Colnbrook is inside, or right on the edge of, the flight restriction zone around Heathrow Airport. Before any flight there, we ask the airport for permission, and the flight only goes ahead if it’s given. A small drone can’t fly safely in high wind or heavy rain.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
How experienced are you?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
What happens after the survey?
You will get the report by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep a record of when stains appear
- Move stored items away from the loft hatch
- Don’t climb onto the roof to look for leaks yourself
- Use the report as a baseline for later checks
Buyers can use the findings when talking to the seller or agent. What you do with it is up to you, whether you ask for work before completion or discuss the price.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Why act early in Colnbrook
Thermal images can suggest the extent of wet areas without cutting into the roof. That helps you and your roofer decide what really needs replacing. Where a roof is exposed, as many are in small places like Colnbrook, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.

What we do, step by step
We check the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes roughly 1–2 hours for a house, and longer for a large or complex roof. Somewhere like Colnbrook needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We check the roof from ground level, from windows and from the roof itself where it is safe.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- You get a report with thermal images, photos and our recommendations.
Before the survey
- Check the loft hatch can be reached
- Dig out any old roof reports or invoices
- Tell us about parking before the day

Thermal roof surveys around Colnbrook
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help. Frogmore House, about 3 miles west, is one of the historic houses in the wider area around Colnbrook. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you look after a building like Colnbrook Church of England Primary School, big roofs are where photos from the air and thermal images show the most at once. Take an older house close to Church of St Thomas: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
