Thermal imaging roof survey in Barnehurst, Greater London
We take a careful look at the roof at your property in Barnehurst, and put it all in a photo-illustrated written report.
- Damp where roofs meet walls and chimneys
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
Thermal roof survey in Barnehurst
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it’s warm inside and cold outside. The report shows the images and explains what they may mean. It is not an energy rating or a heat loss calculation. We’re often asked to look into moisture around outlets and upstands and leaks far from where the stain appears, on insulated roof spaces, pitched roof slopes and loft conversions.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. We take care to focus on the roof we’ve been asked to look at. Mention access, height and anything unusual about the building when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, with the urgent items made clear.

Do you need a thermal roof survey in Barnehurst?
People often book a thermal survey when a damp patch has no obvious cause. Water can travel under a roof covering or along timbers before it shows inside. Temperature patterns can help narrow down where to look.
Things that often lead to a survey include:
- Possible trapped moisture under a flat roof covering
- Cold areas below the roof
- Damp where roofs meet walls and chimneys
- Damp around roof outlets and upstands
Hall Place and Gardens, about 1 mile south-west, is one of the historic houses in the wider area around Barnehurst. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings.

Questions from Barnehurst
Will parking be an issue for a roof survey in Barnehurst?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
How do I find out if my home in Barnehurst is listed?
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.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we’ll agree the details as you book.
Does thermal imaging detect leaks directly?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Note where damp appears and after what weather
- Keep outlets and gutters clear to stop water sitting
- Ask us about the forecast if rain is expected
- Photograph damp patches with the date
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
What this survey can’t tell you
It is a careful look at the roof, not the whole story. Its limits include:
- What’s inside walls or under coverings, without opening up
- A structural engineer’s assessment
- Reliable images in rain, strong wind or on a wet roof surface

What this survey covers

- Loft conversions
- Ceilings below the roof
- Pitched roof slopes
How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. That makes the survey more focused.
Why act early in Barnehurst
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, rather than more guesswork. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, including VAT. We can help you choose the package that fits what you’d like to know.

Thermal roof surveys around Barnehurst
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
For site and facilities teams at buildings such as Mayplace Primary School, a drone or thermal camera can show a large roof in a single visit. As a London address, Barnehurst can be tricky for parking: let us know about parking bays, permits or a driveway as you book, as a space near the door can’t be promised.

What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely. Most surveys take about one to two hours at a typical home, though large, tall or awkward roofs take more time. London terraces rarely offer a view of the whole roof from one spot, so a visit in Barnehurst moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- 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.
- A thermal camera records how the surface temperature varies across the roof.
- 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.
Getting ready for the survey
- If the roof is shared, arrange access with whoever manages the building
- Let us know about parking near the property
- Point out any leaks or damp patches
