Thermal roof survey in St Margarets: what you get
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. There’s a 12-month follow-up as well. We survey commercial roofs, ceilings below the roof and pitched roof slopes, and the problems we are asked to look at most are moisture around outlets and upstands and heat escaping through the roof.
In a small place like St Margarets, open ground can mean strong wind. 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.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Roof by roof
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, when the conditions allow.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
Honest limits
We only report everything that’s safely in view on the day, so there are some things a survey cannot cover:
- A formal energy assessment
- The condition of timbers we can’t see
- Clear results when the conditions on the day are poor
If you are not sure which survey you need, call 07833 053749 or email us and we’ll give you a straight answer. The full list of what we check.

Flying and imaging in St Margarets
The wider area around St Margarets has a long history of building, with Lullingstone Castle about 4.5 miles south-west. 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 any change of roofing material on a listed home needs checking with the council first. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
If you look after a building such as Greenlands Primary School, a drone or thermal camera can show a large roof in a single visit. For businesses in and around places such as Bluewater, a commercial roof can be photographed from above without anyone walking on it.

Useful tips for St Margarets property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Use the report as a baseline for later checks
- Note where damp appears and after what weather
- Ask us about the forecast if rain is expected
- Check the loft can be reached safely
After the visit, we put the thermal images, photographs and moisture readings into one report. We explain what each image may mean, alongside what we recommend. Premium reports are sent the same day.
After repairs or a new covering, a later survey can confirm things are dry in suitable weather.
Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Common questions in St Margarets
Will you come out to St Margarets?
Yes, we do. We survey roofs across London and the South East, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
How do I find out if my home in St Margarets is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is this an asbestos survey?
No. We do not sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance.
Can a thermal camera see water?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
How long does the survey take?
It normally takes roughly 1–2 hours for a house, and about three to four hours for a commercial roof. You’ll then get the report by email, on the timescale of your package.
What happens after the survey?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you need a thermal roof survey in St Margarets?
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
We are frequently asked to look at:
- Wet insulation beneath the membrane
- Water that travels before it shows
- Ceilings that feel colder in places
- Gaps in loft insulation
The streets around a church such as Church of St Margaret of Antioch are often among the oldest in a place, and if your home is one of the older ones nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Questions to ask before you book
- Which viewpoints they use to see the roof
- Whether any drone flown is registered with the CAA
- What experience they bring
- What follow-up you get after the report
How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely, from ground level, from windows, in the roof space and by drone where applicable. The survey typically takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. For a village or hamlet like St Margarets, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can be seen safely, inside and out.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- 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.
- We check the patterns that stand out with moisture readings where there is safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Make a note of anything you’d like us to look at
- Let us know where we can park nearby
