New Barn Thermal Roof Survey
Thermal roof surveys for homes and businesses in New Barn. We’ve completed more than 5,000 surveys across London and the South East.
- Wet insulation beneath the membrane
- Damp around chimneys and parapets
- Damp that repairs haven’t cured
Tips from our surveys
Here are a few things we’d tell any owner:
- Ask us about the forecast if rain is expected
- File the images with your roof records
- Clear leaves from outlets and gutters each autumn
- Check the loft can be reached safely
Where a pattern can’t be confirmed, the report says what could help, such as electronic leak detection or opening up a small area.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
How a thermal roof survey works in New Barn
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. Common reasons to book are cold areas below the roof and water getting in at parapets and stacks, on pitched roof slopes, insulated roof spaces and flat roofs.
Places like New Barn can be near small airfields or other airspace restrictions, so the Drone Safety Map is checked before any flight. Exposed sites can be windy, and a small drone can’t fly safely in strong wind, while thermal imaging also works best with little wind. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

What we cannot see
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- A formal energy assessment
- Hidden layers that need to be opened up to check
- A structural engineer’s assessment

DIY checks: what’s safe
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
For landlords and managing agents
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
What we look for on each type of roof
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Airspace, weather and New Barn roofs
The coast is about 5 miles or less from New Barn. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
If you live in an older home near Church of Saint Mary Magdalene, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. Historic houses like Cobham College, about 3.1 miles east, show how far back building around New Barn goes. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. If you run a business near Bluewater, big, flat commercial roofs are where photos from the air and thermal images help most.

How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes about 1–2 hours on an ordinary house, though large, tall or awkward roofs take more time. Homes around New Barn often have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- Agree roof access with the managing agent if it’s shared
- If you’re buying, let the agent know when we are coming

Questions from New Barn
Is my home in New Barn listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Is New Barn in the area you cover?
Yes. We survey roofs across London and South East England, and New Barn is part of that. You can phone 07833 053749 or send us an email with the address and a few details.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Will thermal imaging find my leak?
It frequently helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It’s used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.
How much does a thermal roof survey cost?
It comes with our Premium Survey, which starts from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
