Barnsbury Thermal Roof Survey
Not sure what state the roof is in? We carry out thermal roof surveys in Barnsbury and across Greater London, with plain-English findings.
- Heat escaping through the roof
- Cold areas below the roof
- Damp patches with no obvious cause
Why act early in Barnsbury
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. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 with VAT included. We’ll tell you which package suits the questions you have.
Why book us in Barnsbury
- Every finding written up with photos
- Two decades and more of roof surveys
- Drones and thermal imaging where it applies
- CAA-registered drone operator (Flyer ID and Operator ID)

Thermal roof survey in Barnsbury: what you get
A thermal survey can point to places where heat is escaping through the roof. Missing or slipped insulation and gaps at the eaves frequently show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. We survey ceilings below the roof, loft conversions and commercial roofs, and the problems we’re asked to look at most are cold areas below the roof and damp where roofs meet walls and chimneys.
Flying in London takes more checking than most places: 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. Before a drone goes up in Barnsbury, the address is checked against all of them, and permission is never taken for granted.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Thermal roof surveys around Barnsbury
Barnsbury has a number of hotels within about a mile and a half. If you look after one, a large roof can be surveyed without guests having anyone working above them. About 2.1 miles south lies Dr Johnson's House, a reminder of how long the area around Barnsbury has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you run a business near Brunswick Centre, big, flat commercial roofs are where close-up aerial shots and thermal images help most. If you run a hotel or guest house in or near Barnsbury, a roof problem can mean rooms out of use, so it pays to find faults before guests do. Anyone responsible for a site like Robert Blair School will know that thermal images can show where wet insulation sits under a big flat roof.

What you can safely check yourself
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
What happens on the day
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take about 1–2 hours on an ordinary house, and more on a big or complicated roof. In a London conversion, the way into the roof space is frequently from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Find any records of previous roof work
- Tell us where we can park nearby
- If you are buying, check with the agent that we can get in

Prices for thermal roof surveys in Barnsbury
We confirm the price for your survey before booking. This is what makes a difference:
- The height of the building and how the roof can be seen safely
- Chimneys, valleys, parapets and other details
- Whether thermal imaging or a drone is needed
- Basic, Standard or Premium
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Prices start from £400, including VAT.
Getting in touch
You do not need to know any roofing terms. Just let us know:
- Where any leaks, stains or damp patches show inside
- What kind of property and roof it is
- Pictures from the garden or a window, if you have them
- What made you get in touch
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or email us.
How the survey changes by roof type
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. We use the camera and moisture readings to help follow it.
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there is a pattern around them.
For landlords and managing agents
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
FAQs for Barnsbury
Does a conservation area affect roof work in Barnsbury?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Can parking be tricky for a visit in Barnsbury?
It depends on the street. If Barnsbury has controlled parking where you are, a visitor permit is the easiest answer.
How much does a thermal roof survey cost?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where applicable, structural analysis and a report on the same day.
Do you work in Barnsbury?
Yes. We survey roofs across London and South East England, Barnsbury included.
What’s the best way to book?
The quickest way is to call 07833 053749 or drop us an email. Tell us the address and a little about the roof, and we’ll point you to the right survey. We survey on weekdays and at weekends.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
How long does the survey take?
Expect it to take an hour or two for most homes, plus time to check any thermal findings with moisture readings. You will then get the report by email, on the timescale of your package.
