Bermondsey Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof around Bermondsey, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Damp around chimneys and parapets
- Thin or uneven insulation in the roof
- Damp patches with no obvious cause
How a thermal roof survey works in Bermondsey
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. We back up the images with moisture readings and a careful look at the roof. The report is clear about what the images show and what they do not. If a finding cannot be confirmed, the report suggests a next step. We are frequently asked to look into ceilings that feel colder in places and missing or slipped insulation, on insulated roof spaces, commercial roofs and pitched roof slopes.
Flying in London takes more checking than most places: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every address in Bermondsey is checked before any drone flight, and where permission is needed, the flight waits for it.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
What a survey costs
A few things affect what a survey costs:
- Any need for thermal images or a drone flight
- Which survey package you book
- Features like valleys, chimneys, dormers and parapets
- House, block, shop or office
To find out what your survey will cost, phone 07833 053749 or drop us an email with the address and some details. We will confirm the figure before booking.
Booking your survey
To price your survey accurately, we’ll ask about:
- Where any leaks, stains or damp patches show inside
- Dates you are working to, such as exchange
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
Prices start from £400, including VAT. The exact figure depends on the roof and the package, so phone 07833 053749 or send us an email with the details.
What we are asked to look at in Bermondsey
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
A survey makes sense if you’ve noticed:
- Wet areas near outlets and upstands
- Damp that repairs haven’t cured
- Wet insulation beneath the membrane
- Heat escaping through the roof
Anyone responsible for a site like Boutcher Church of England Primary School will know that a drone or thermal camera can show a large roof in a single visit.
Before you book any roof surveyor
- What experience they bring
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What exactly goes into their report
- Whether VAT is in the quoted price
The survey, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. London terraces rarely offer a view of the whole roof from one spot, so in Bermondsey we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s 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.
Before we arrive
- For a flat or shared roof, check access with whoever owns or manages the building
- Leave a clear route to the loft
- Tell us about any leaks, stains or damp patches you know of
Book a survey
A quick phone call is usually the easiest start: ring 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.

What else we do in Bermondsey
Different roofs, different checks
GRP fibreglass roofs
Glossy GRP can reflect heat. We allow for reflections and confirm findings with moisture readings.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
Drones, thermal imaging and Bermondsey roofs
The restricted area over the City of London, where drone flights need permission from NATS, is about 2 miles from Bermondsey. Where the drone is part of the survey, we check whether the address falls inside it before flying. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
Shop and office owners around Surrey Quays Shopping Centre may find that big, flat commercial roofs are where aerial photos and thermal images help most. For a London address like Bermondsey, it is useful to know about controlled parking before the day.

Your questions about thermal roof surveys in Bermondsey
Can you fly a drone over a roof in Bermondsey?
It depends on the exact address and the weather on the day. Bermondsey is about 2 miles from the restricted area over the City of London, where drone flights need permission from NATS. If a roof falls inside it, we apply for permission before flying, and the flight only goes ahead if it’s granted. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Strong wind or a downpour also stops a small drone flying, though the rest of the survey goes ahead either way.
Is parking a problem for a survey in Bermondsey?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the building owner or managing agent. We can only inspect what we’re given access to.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
Which survey includes thermal imaging?
Thermal imaging is included in our Premium Survey, from £400. The Premium Survey also covers a full inspection, drone inspection where it applies, structural analysis and a report on the same day.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access.
