About our thermal roof survey in Knotty Green
A thermal survey isn’t a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. Where something cannot be confirmed, we say what would help next. If you are worried about damp that repairs haven’t cured and wet areas near outlets and upstands, a survey will tell you what’s going on, on insulated roof spaces, loft conversions and pitched roof slopes alike.
In a small place like Knotty Green, open ground can mean strong wind. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

What this survey cannot tell you
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- A formal energy assessment
- Hidden layers that need to be opened up to check
- Readings unaffected by sun, shade or reflections

FAQs for Knotty Green
Do you carry out roof surveys in Knotty Green?
Yes, Knotty Green is one of the places we work. The survey and report are the same in Knotty Green as anywhere else, and visits run on weekdays and weekends.
Will you come out to Knotty Green?
Yes, we do. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Does thermal imaging detect leaks directly?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
What does the report include?
Written findings with photographs, explaining the condition of the roof, any defects and our recommendations, by urgency where it matters. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Common roof problems in Knotty Green
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, especially when it’s warm inside and cold outside.
People normally book a survey when they’ve noticed something like this:
- Areas losing heat at the eaves and junctions
- Water getting in at parapets and stacks
- Leaks that are hard to trace
- Gaps in loft insulation
For site and facilities teams at buildings such as St Mary and All Saints CofE Primary School, thermal images can show where wet insulation sits under a big flat roof.
Before booking anyone
- Whether the roof space is looked at, where there is one
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Are they insured for the work?
- How they’ll see the roof: from the ground, the loft, the roof or by drone
For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant, which helps with budgets and planning.
Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Check from ground level or a window, never by climbing
- Keep the report to compare against after any repair
- Tell us where and when you’ve seen damp or stains
- Photograph damp patches with the date
If you’re buying, the report gives you specific points to raise with the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. The less water sits, the less can find its way beneath.
Thermal roof surveys in Knotty Green: local notes
With Cliveden about 4.6 miles south, Knotty Green sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Some villages in Buckinghamshire still have thatched roofs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help.
If your home is one of the older ones in the streets near Church of St Michael and All Angels, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

What happens on the day
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes roughly 1–2 hours for a house, though large, tall or awkward roofs take more time. Older rural homes like those around Knotty Green can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Jot down any questions you want answered
- Dig out any old roof reports or invoices
- Keep pets out of the way during the survey

Advice
Different roofs, different checks
GRP fibreglass roofs
Glossy GRP can reflect heat. We take that into account and check findings with moisture readings.
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We combine the images with an inspection from the loft where there is safe access.
