Thermal roof surveys for homes and businesses in Burnham Green
What a thermal camera can show depends a lot on the weather. A sunny day before the survey, a dry roof surface and little wind all help. Rain, wind and cloud can all make the patterns weaker. We will discuss the weather with you when booking, and the report explains how the conditions on the day affected the results. Common reasons to book are cold spots on ceilings under the roof and leaks far from where the stain appears, across flat roofs, insulated roof spaces and ceilings below the roof.
Villages like Burnham Green often stand in open country, where wind can be strong. 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. A change in the forecast can mean moving the visit to another day.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What we look for on each type of roof
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. The camera can give clues to where it is sitting, when the conditions allow.

What else we do in Burnham Green
What a thermal roof survey looks like in Burnham Green
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
Historic houses like Digswell House, about 1.9 miles south-west, show how far back building around Burnham Green goes. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. Anyone responsible for a site like Monk's Walk School will know that big roofs are where photos from the air and thermal images show the most at once.

Why get it checked now?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Older cottages and farmhouses around Burnham Green can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
Thermal roof survey starts from £400, including VAT. What you pay depends on how big and how high the roof is, how it can safely be seen and which survey you book.

The survey, step by step
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, it typically takes about 1–2 hours at most homes, and more on a big or complicated roof. Cottages and farmhouses around Burnham Green often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Let us know about parking near the property
- For flats, check roof access has been agreed
- Keep pets out of the way during the survey
Booking a survey
Photos help, if you have them. Take them safely from the ground or a window, and please do not climb up for a closer look. To send them or to book, phone 07833 053749 or email us.
Related advice
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Burnham Green questions
Do you carry out roof surveys in Burnham Green?
Yes, Burnham Green is one of the places we work. The survey and report are the same in Burnham Green as anywhere else.
Does a conservation area affect roof work in Burnham Green?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you as you book.
Is thermal imaging good for finding leaks?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It is used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.
Will the survey show heat loss through my roof?
Gaps and thin areas of insulation can show up on the camera. It shows most clearly when it’s warm inside and cold outside. Where we can reach the loft safely, we check there too.
Will the camera show exactly where the water is?
The camera doesn’t see water itself. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Does thermal imaging work on slate and tile roofs?
It can help, but the results are often less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it is safe.
Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer.
Signs you need a thermal roof survey in Burnham Green
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Signs worth acting on include:
- Damp where roofs meet walls and chimneys
- Patches of heat loss across the roof
- Cold areas below the roof
- Wet areas near outlets and upstands
If you run a business near Howard Centre, thermal images can show trapped moisture across a wide commercial roof.
