How a thermal roof survey works in Sacombe Green
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we also look from the loft where we can reach it safely. If you’ve noticed possible trapped moisture under a flat roof covering and thin or uneven insulation in the roof, a survey will tell you what’s going on, whatever the roof.
Villages like Sacombe Green frequently 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. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

How the survey changes by roof type
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences frequently show through. Any patterns are checked with moisture readings.
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We combine a visual check of cracks with the thermal images around them.

What else we do in Sacombe Green
The survey, step by step
The visit has one job: to look at the roof as closely as is safe and record what we find. Notes and photographs go into the written report. It usually takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older rural homes like those around Sacombe Green 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 can’t 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.
- We inspect the roof and take thermal images during the same visit.
- 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
- If it is not your property yet, arrange access through the agent
- Mention any parking restrictions on your street
- Find any records of previous roof work

Common roof problems in Sacombe Green
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there’s a clear difference between inside and outside.
People usually book a survey when they’ve noticed something like this:
- Areas of a flat roof that may hold water
- Ceilings that feel colder in places
- Damp where roofs meet walls and chimneys
- Water that travels before it shows
Take a building like Ralph Sadleir Middle School: thermal images can show where wet insulation sits under a big flat roof.
Questions to ask before you book

Questions from Sacombe Green
Is my home in Sacombe Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Sacombe Green within the area you cover?
Yes. Sacombe Green is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route as you book.
How does a thermal imaging roof survey work?
The camera records how the surface temperature varies. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
How experienced are you?
Over 20 years and more than 5,000 surveys.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The report is sent afterwards by email.
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
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. Do not go up yourself.

Airspace, weather and Sacombe Green roofs
The wider area around Sacombe Green has a long history of building, with Aston Bury about 4.4 miles west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place.
The streets around a church such as Church of St Katherine are often among the oldest in a place, and if yours is one of the older homes nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
