Thermal imaging roof survey in West Hendon, Greater London
A careful look at the roof at your property in West Hendon, with photos and a written report.
- Damp around roof outlets and upstands
- Missing or slipped insulation
- Ceilings that feel colder in places
When to book a survey in West Hendon
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
These are some of the problems a survey can pick up:
- Cold areas below the roof
- Leaks that are hard to trace
- Damp patches with no obvious cause
- Areas losing heat at the eaves and junctions
Parking in West Hendon, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway as you book.
Choosing a roof surveyor
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Will the report include photos?
- Their report turnaround times
- Whether the inside of the roof is included
About our thermal roof survey in West Hendon
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. Moisture readings are then used to check what the camera suggests. We survey pitched roof slopes, commercial roofs and flat roofs, and the problems we’re asked to look at most are damp patches with no obvious cause and cold areas below the roof.
London’s roofs are often hard to see from the street: 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. Weather on the day decides whether it goes ahead, in West Hendon as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
What you get is a clear record of the roof on the day we saw it. It is useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

How we price thermal roof surveys
A few things affect what a survey costs:
- Roof area
- How tall the building is and how easy the roof is to see
- The number of roofs, including extensions and garages
- How complicated the roof is, with its valleys, chimneys and parapets
To find out what your survey will cost, ring 07833 053749 or drop us an email with the address and some details. We will confirm the figure before booking.
What to let us know when you get in touch
The more you tell us, the easier it is to price the survey. When you get in touch, it is useful to mention:
- When you need the report by
- Any stains, drips or damp patches you’ve seen indoors
- Access details, such as a loft hatch or a shared roof
- The type of building and roof, like pitched or flat
For a price for thermal roof surveys in West Hendon, ring 07833 053749 or email us. The address, the type of property and what you’d like to know help us give you an accurate price.
Roof by roof
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. Wet boards can show as temperature differences on the images.
Flying and imaging in West Hendon
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. 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 the drone is used for your survey, the flight is checked against the Drone Safety Map first.
Heath House lies about 3.2 miles south-east, so building around West Hendon goes back a long way. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition. Shop and office owners around Brent Cross Shopping Centre may find that big, flat commercial roofs are where aerial photos and thermal images help most.

Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Landlords, agents and building managers in West Hendon and across Greater London can book any of our surveys. To discuss a property or a block, ring 07833 053749 or email us.
How the survey works
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Point out any leaks or damp patches
- Make a note of anything you’d like us to look at
- Leave a clear route to the loft
Booking a survey

Related advice
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking.
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. Leave anything above ground level to a survey.
Your questions about thermal roof surveys in West Hendon
Does a conservation area affect roof work in West Hendon?
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, and councils can also use Article 4 directions.
Will parking be an issue for a roof survey in West Hendon?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Does this replace a RICS home survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Will you photograph what you find?
Yes, plenty. Pictures sit next to the findings they show.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access as you book.
Are you structural engineers?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. We do not give energy ratings or heat loss calculations, but the images show where improvements may help.
