How a thermal roof survey works in High Barnet
A thermal survey is not a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. That’s why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they don’t. If a finding cannot be confirmed, the report suggests a next step. We survey commercial roofs, flat roofs and pitched roof slopes, and the problems we are asked to look at most are ceilings that feel colder in places and damp patches with no obvious cause.
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. Let us know about the building and access as you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
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.

Do you need a thermal roof survey in High Barnet?
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
We are often asked to look at:
- Thin or uneven insulation in the roof
- Wet areas near outlets and upstands
- Patches of heat loss across the roof
- Wet insulation beneath the membrane
Shop and office owners around Spires Shopping Centre may find that thermal images can show trapped moisture across a wide commercial roof.
Choosing a roof surveyor
- Whether VAT is added on top
- Whether you can ask questions once you have the report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included

Airspace, weather and High Barnet roofs
The wider area around High Barnet has a long history of building, with Wyllyotts Manor about 2.9 miles north. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
Take a building like Foulds School: thermal images can show where wet insulation sits under a big flat roof. Controlled parking zones are common in London, so mention any permit rules for High Barnet.

What a survey costs
To price your survey, we look at:
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
- Building height and the viewpoints available
- The type of building, from a house to a block or an office
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Getting in touch
What helps most when you contact us:
- What made you get in touch
- Where any leaks, stains or damp patches show inside
- The type of building and roof, like pitched or flat
- Any deadline, like an exchange date
Our price is from £400, including VAT. The exact figure depends on the roof and the package, and you can phone 07833 053749 or email us to find out.
Before and after the survey
Some practical points come up on survey after survey. They apply to most roofs:
- Keep a record of when stains appear
- Leave the roof to people with safe access
- Heat the home normally on the days before
- File the images with your roof records
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, with our recommendations. With a Premium Survey, you get the report the same day.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
Your questions about thermal roof surveys in High Barnet
Will parking be an issue for a roof survey in High Barnet?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. That way the visit can be planned around it.
Are there drone restrictions around High Barnet?
That depends on where the roof is and on 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. 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. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Is thermal imaging useful on pitched roofs?
It can help, but the results are often less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we combine it with an inspection from the loft where there’s safe access.
How do I arrange a thermal roof survey in High Barnet?
Just phone 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We look at the parts we’re given access to, and the report makes that clear.
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, take photos as we go and make notes for the report. Most visits take between one and two hours on an ordinary house, and longer for a large or complex roof. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in High Barnet runs like any other.
- 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.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Jot down any questions you want answered
- Have keys ready for side gates, garages or roof access doors
Book a survey
Most bookings start with a short call: phone 07833 053749 or send us an email and we will ask a few questions about the roof. You will have a price before anything is arranged.

How the survey changes by roof type
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.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We inspect the loft where it can be reached safely.
What this survey cannot tell you
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Confirming water without moisture readings
- An energy rating for the building
- Clear results when the conditions on the day are poor
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey before you book. What a survey covers and doesn’t.
What we check
- Insulated roof spaces
- Commercial roofs
- Ceilings below the roof
- Pitched roof slopes
- Loft conversions
- Flat roofs
