Finchley Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Finchley, using drones and thermal imaging where applicable. Call or email for a price.
- Moisture around outlets and upstands
- Water getting in at parapets and stacks
- Damp patches with no obvious cause
Landlords, agents and block managers in Finchley
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps when budgeting.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
How a thermal roof survey works in Finchley
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it’s colder 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. If you’re worried about cold areas below the roof and damp patches with no obvious cause, a survey will tell you what’s going on, on pitched roof slopes, insulated roof spaces and commercial roofs alike.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. We take care to focus on the roof we’ve been asked to look at. Mention access, height and anything unusual about the building when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Prices for thermal roof surveys in Finchley
Several things affect the price of a survey:
- If the survey needs thermal imaging or a drone
- Features like valleys, chimneys, dormers and parapets
- The size of the roof
- Whether it is a home or a commercial building
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What to tell us when you contact us
If you can, have these to hand when you contact us:
- Anything about access we should know
- Pictures from the garden or a window, if you have them
- What made you get in touch
- Any deadline, such as an exchange date
Once you know what you need, ring 07833 053749 or send us an email. We will suggest a package, agree the price and find a date.
The survey, step by step
After the inspection, everything we found is written up as a report with photos, sent to you by email. On timing, most surveys take about 1–2 hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. In Finchley, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when booking.
- You let us know about the roof and any damp, leaks or cold rooms.
- 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.
How to prepare
- Let us know where we can park nearby
- Keep pets in another room
- Have any paperwork from past roof work to hand

How the survey changes by roof type
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. The camera can give clues to where it is sitting, given suitable conditions on the day.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. We check any patterns with moisture readings.
What we are asked to look at in Finchley
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
Look out for signs like these:
- Thin or uneven insulation in the roof
- Damp patches with no obvious cause
- Moisture around outlets and upstands
- Wet insulation beneath the membrane
For a London address like Finchley, it is useful to know about controlled parking before the day.
Questions to ask before you book
- Is there a chance to talk the report through?
- Whether you get a written report with photos
- What experience they bring
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
When you need someone else
It is a careful look at the roof, not the whole story. The main limits are:
- Clear results when the conditions on the day are poor
- Insulation values or heat loss calculations
- Proving moisture from the images alone
If in doubt, ring 07833 053749 or email us and we will suggest the right survey before you book. What our survey covers.
What we look at
- Flat roofs
- Loft conversions
- Insulated roof spaces
- Commercial roofs
- Pitched roof slopes
- Ceilings below the roof
Drones, thermal imaging and Finchley roofs
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Finchley is one of them, bay roofs, hips and later dormers each have their own details. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
For businesses in and around places such as Grand Arcade, big, flat commercial roofs are where photos from the air and thermal images help most. For site and facilities teams at buildings such as Manorside Primary School, a drone or thermal camera can show a large roof in a single visit.

Finchley: your questions answered
Does a conservation area affect roof work in Finchley?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you fly a drone over a roof in Finchley?
Normally it comes down to two things: the airspace at the address and the weather. 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, though the rest of the survey goes ahead either way.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
Will you photograph what you find?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
What happens next?
You will get the report by email, with photos and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
What insurance do you have?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
