About our thermal roof survey in Bexley
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’re worried about damp patches with no obvious cause and damp where roofs meet walls and chimneys, we can find out what’s behind it.
Many London roofs are hidden from the pavement: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Tips from our surveys
From years of surveys, a few habits stand out:
- Keep outlets and gutters clear to stop water sitting
- Keep the heating on as usual before a heat loss survey
- Keep dated photos of any marks on ceilings
- Keep the report to compare against after any repair
After the visit, we put the thermal images, photos and moisture readings into one report. We explain what each image may mean, with our recommendations. With a Premium Survey, you get the report the same day.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.

What we look for on each type of roof
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
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.
How the survey works
The visit has one job: to see as much of the roof as can be seen safely and record it clearly. Notes and photographs go into the written report. It usually takes an hour or two for a house, and longer for a large or complex roof. For a visit in Bexley, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- The roof is inspected visually from safe viewpoints.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Before the survey
- Have any questions written down, so nothing gets missed
- Check pets are kept safely away
- Tell us where we can park nearby

Thermal roof surveys in Bexley: local notes
Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. Historic houses like Red House, about 0.9 miles north, show how far back building in the area around Bexley goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings such as Old Bexley Church of England School, a drone or thermal camera can show a large roof in a single visit. If your house is among the older ones in the streets near Parish Church of St John the Evangelist, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

What affects the cost of thermal roof surveys
Every roof is different, so prices are confirmed before booking. This is what makes a difference:

- How many separate roofs there are, like extensions, dormers and garages
- The roof’s overall size
Every price we give includes VAT, and the report is not charged as an extra. Our price is from £400, including VAT. Size, height and access decide where your roof falls.
What we need to know
Getting the details right at the start saves time. It helps to include:

- Your postcode, so we can check access and travel
- Anything about access we should know
- What kind of property and roof it is

Signs you need a thermal roof survey in Bexley
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
Signs worth acting on include:
- Leaks that are hard to trace
- Moisture around outlets and upstands
- Thin or uneven insulation in the roof
- Ceilings that feel colder in places
For a London address like Bexley, it’s useful to know about controlled parking before the day.

Questions from Bexley
Can parking be tricky for a visit in Bexley?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Is my home in Bexley listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What’s the best way to book?
It is easiest to phone 07833 053749 or use the contact form. Let us know the address and a little about the roof. Surveys run on weekdays, Saturdays and Sundays.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
What does a thermal roof survey show?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
