We carry out thermal roof surveys in New Barnet and the rest of Greater London. Surveys run seven days a week.
- Ceilings that feel colder in places
- Heat escaping through the roof
- Possible trapped moisture under a flat roof covering
Thermal roof surveys for homes and businesses in New Barnet
Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where applicable, structural analysis and a report on the same day. There is an in-person consultation as well, plus a follow-up 12 months later. You can ring 07833 053749 or use the contact form with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We are often asked to look into cold areas below the roof and moisture around outlets and upstands, on insulated roof spaces, pitched roof slopes and commercial roofs.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. Images are taken to show the roof we are surveying, with care for neighbours’ privacy, in New Barnet 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.
The report records the roof as we found it on the day. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

Flying and imaging in New Barnet
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. 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 aerial photos and thermal images help. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
Wyllyotts Manor lies about 3.8 miles north, so building around New Barnet goes back a long way. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. Anyone responsible for a site like St Mary's CofE Primary School will know that big roofs are where close-up aerial shots and thermal images show the most at once.
New Barnet is about 1 mile east of Barnet, in Greater London. From houses to flats and shops in New Barnet, the roof can be surveyed. New Barnet is one of the places in Greater London we cover for thermal roof surveys. For surveys nearby, see our London page.

When you need someone else
A survey is a careful look at the roof, but it can’t do everything. Its limits include:
- Seeing water directly, as the camera shows temperature, not moisture
- Reliable images in rain, strong wind or on a wet roof surface
- A formal energy assessment
If in doubt, call 07833 053749 or email us and we’ll recommend the right survey. What our survey covers.

Questions from New Barnet
How do I find out if my home in New Barnet is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can you fly a drone over a roof in New Barnet?
It depends on the exact address and the weather 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. Strong wind or a downpour also stops a small drone flying.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Will you walk on the roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.

What happens on the day
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. Most surveys take an hour or two for most houses, and more on a big or complicated roof. Surveys in New Barnet can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Make sure we can get to the back of the property
- Leave a clear route to the loft
- For a flat or shared roof, check access with the building owner or managing agent
Arrange a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.
Advice
What we look for on each type of roof
Pitched slate and tile roofs
Thermal images of a pitched roof can still show heat loss patterns and some damp areas. We explain what can and can’t be read from them.
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. The camera can help show damp around these junctions.
For landlords and managing agents
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer.
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or send us an email.
Common roof problems in New Barnet
Some owners book because the rooms under the roof feel cold. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
Here are some of the things we see frequently:
- Possible trapped moisture under a flat roof covering
- Damp patches with no obvious cause
- Damp where roofs meet walls and chimneys
- Wet areas near outlets and upstands
As a London address, New Barnet can be tricky for parking: a visitor permit or a nearby bay makes the day easier.
Before booking any roof surveyor
- Whether the loft is part of the inspection
- What the survey will not cover
- Whether VAT is added on top
- Their track record with similar roofs
