Thermal imaging roof survey in Chislehurst, Greater London
Know where you stand with the roof before you spend money on it. Thermal roof surveys in Chislehurst, with photos and a clear written report.
- Damp that repairs haven’t cured
- Wet insulation beneath the membrane
- Water getting in at parapets and stacks
What we’re asked to look at in Chislehurst
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
People normally book a survey after spotting one of these:
- Wet areas near outlets and upstands
- Ceilings that feel colder in places
- Areas of a flat roof that may hold water
- Leaks far from where the stain appears
Historic houses such as Bromley Palace, about 2 miles south-west, show how far back building around Chislehurst goes. Aerial photos and thermal images let an old roof be checked without anyone disturbing it.
Before booking any roof surveyor
- What the report includes, and whether it has photos
- How long they’ve been surveying roofs
- Whether the loft space is looked at, where there is one
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
How a thermal roof survey works in Chislehurst
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging frequently helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. Typical surveys look at leaks far from where the stain appears and heat escaping through the roof, across flat roofs, pitched roof slopes and ceilings below the roof.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Every address in Chislehurst is checked before any drone flight, and permission is never taken for granted.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend.

What happens if roof problems are left?
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Any roof job in Chislehurst means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan.
Prices start from £400, including VAT. The final price depends on how big and how high the roof is, access and the package you choose.

What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Other services in Chislehurst
Landlord and commercial surveys in Chislehurst
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant ahead of time.
Different roofs, different checks
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.
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. We use the camera and moisture readings to help follow it.
What a thermal roof survey looks like in Chislehurst
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
If you live in an older home near Parish Church The Annunciation Of Blessed Virgin Mary, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from the air or with a thermal camera helps. Take a building like Red Hill Primary School: a view from above covers a wide roof far faster than walking it.

Chislehurst questions
Are there drone restrictions around Chislehurst?
The answer turns on the exact location and the conditions on the day. 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. Each address is checked against all of them before the drone goes up. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
Is my home in Chislehurst listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
Do you work in Chislehurst?
Yes. We survey roofs across London and South East England, and that includes Chislehurst.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we will plan the survey around it.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Is thermal imaging included in your surveys?
It’s part of the Premium Survey, from £400. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
What we do, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a London area like Chislehurst, the main things to sort out are parking and access: 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 everything that’s safely in view from the ground, windows, the loft and, where it’s safe, the roof itself.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- If it is not your property yet, arrange access through the agent
- Dig out any old roof reports or invoices
- Keep pets inside or away from the areas we are looking at
