Thermal imaging roof survey in Queensbury, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof in Queensbury, carried out by an experienced roof surveyor. Every survey comes with a written report and photos.

Queensbury: your questions answered
Is drone flying allowed in Queensbury?
Typically it comes down to two things: the airspace at the address and the weather. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. A small drone can’t fly safely in strong wind or a downpour, though the rest of the survey goes ahead either way.
Can parking be tricky for a visit in Queensbury?
Usually it’s manageable with a little notice. Let us know the parking rules on your street and we will work around them.
How long will you be at the property?
Most surveys take between one and two hours at most homes, or half a day or so for a commercial building. We’ll confirm the timing when booking.
What happens after the survey?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. The survey is not an energy rating or a heat loss calculation, but the report shows where to look more closely.
Thermal roof survey in Queensbury
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a 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. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’ve noticed possible trapped moisture under a flat roof covering and cold spots on ceilings under the roof, a survey will tell you what’s going on, on pitched roof slopes, insulated roof spaces and commercial roofs alike.
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, in Queensbury as anywhere. Let us know about the building and access when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What we look for on each type of roof
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Tips from our surveys
You don’t need to be a roofer to help. Here’s what helps most:
- Remember the conditions on the day affect the results
- Do not climb onto the roof to look for leaks yourself
- Keep the heating on as usual before a heat loss survey
- Clear leaves from outlets and gutters each autumn
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is frequently moved when people work in the loft space.
Landlords, agents and block managers in Queensbury
Businesses and commercial landlords can book us too. Larger roofs take longer, and they’re priced for the size.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
The survey, step by step
The aim of the visit is simple: to see as much of the roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. The visit usually takes about 1–2 hours for a house, and longer for a large or complex roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in Queensbury moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. 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 is safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Before the survey
- Point out any leaks or damp patches
- If you are buying, check with the agent that we can get in
- Leave side gates unlocked

Any roof job in Queensbury means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.

Thermal roof surveys in Queensbury: local notes
About 2.7 miles west lies Headstone Manor, a reminder of how long the area around Queensbury has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
For businesses in and around places like Broadwalk Centre, thermal images can show trapped moisture across a wide commercial roof. If you live in an older home near All Saints Church, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Take a building like Glebe Primary School: thermal images can show where wet insulation sits under a big flat roof.

- The condition of timbers we cannot see
- Whether the deck or roof structure is strong enough
- Proving moisture from the images alone
