Thermal Roof Survey in Ashendon
Independent thermal roof surveys in Ashendon. We have completed more than 5,000 surveys across London and the South East.
- Possible trapped moisture under a flat roof covering
- Patches of heat loss across the roof
- Cold spots on ceilings under the roof
How a thermal roof survey works in Ashendon
We present each thermal image next to a normal photo of the same area, so it is easy to see which part of the roof each one shows. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. If you have questions, the in-person consultation gives you time to go through them. There is a 12-month follow-up as well. We survey flat roofs, ceilings below the roof and insulated roof spaces, and people most often book us about heat escaping through the roof and damp where roofs meet walls and chimneys.
Somewhere as small as Ashendon, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what can’t be reached safely. Both the forecast and the airspace are checked first. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
Where we can’t see part of the roof, the report says so. That way, it’s clear what was covered and what wasn’t.

Thermal roof surveys in Ashendon: local notes
A number of Buckinghamshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
With Waddesdon Manor about 2.3 miles north-east, the area around Ashendon has a long history. Older roofs nearby can be steep and hard to see from the ground, and a survey from above or with a thermal imager doesn’t touch the roof itself.
Ashendon is about 5 miles north of Thame, in Buckinghamshire. From houses to flats and shops in Ashendon, we can survey the roof on a weekday or at the weekend. Our Buckinghamshire coverage includes Ashendon and the places around it. Our Oxford page covers surveys nearby.
We survey roofs across HP18 for thermal roof surveys. You will find streets such as Main Street, Lower End and The Close. Neighbouring places we cover for thermal roof surveys include Nether Winchendon (2 miles south-east), Westcott (2 miles north-east), Upper Winchendon (2 miles east), Waddesdon (3 miles north-east) and Wormstone (3 miles north-east). We also work in nearby towns like Aylesbury (7 miles east), Buckingham (12 miles north), Elmhurst (7 miles east), Southcourt (7 miles east), Princes Risborough (9 miles south-east) and Haydon Hill (6 miles east).
Near you in Ashendon
The closest station to Ashendon is Haddenham & Thame Parkway station, about 3.9 miles south-east. Nearby you will also find Dinton Castle (4.1 miles south-east) and St John's Hospital (4.6 miles east). Green spaces nearby include Snakemoor.
What happens on the day
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older rural homes like those around Ashendon can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- 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.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- Let us know about parking near the property
- Keep pets inside or away from the areas we’re looking at
- Leave a clear route to the loft

Advice
Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the visit with that in mind.
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Your questions about thermal roof surveys in Ashendon
How do I find out if my home in Ashendon is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Ashendon?
Yes. We cover the whole of London and South East England, and Ashendon is part of that. Just ring 07833 053749 or use the contact form and let us know about the property.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report.
Does the weather affect a thermal survey?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. Our report notes the conditions and how they affected the findings.
What’s the best way to book?
The quickest way is to phone 07833 053749 or use the contact form. Give us the address and a few details about the roof, and we will take it from there. We survey on weekdays, Saturdays and Sundays.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Does thermal imaging work on slate and tile roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Roof by roof
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. The camera can help show damp around these junctions.
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We check cracks by eye and use the images to see whether there is a pattern around them.
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. Older and listed buildings around Ashendon may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, with VAT included. We will tell you which package suits the questions you have.
Why book with us
- Weekday and weekend surveys
- Photographs and a written report every time
- Two decades and more of roof surveys
- Packages from £150, with VAT included
Signs you need a thermal roof survey in Ashendon
Not every roof problem shows on the surface. Wet insulation, gaps in insulation and heat loss are often invisible from outside. Thermal imaging gives us another way to look for them.
A survey makes sense if you’ve noticed:
- Damp around roof outlets and upstands
- Areas losing heat at the eaves and junctions
- Damp where roofs meet walls and chimneys
- Gaps in loft insulation
Take an older house close to Parish Church of St Mary the Virgin: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from above or with a thermal imager helps.
Questions to ask before you book
- Are they insured for the work?
- What experience they bring
- Which parts of the roof they’ll actually see
- Will they check the loft as well as the outside?
