Thermal roof survey in Highgate: what you get
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. Typical surveys look at areas losing heat at the eaves and junctions and damp around roof outlets and upstands, on loft conversions, flat roofs and pitched roof slopes.
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 when you book. The extra view helps most on steep slopes, tall stacks and rear additions.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put by urgency where it matters.

Thermal roof surveys in Highgate: local notes
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Steep or complicated roofs are often hard to see from ground level, which is where photos from the air and thermal images help. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
For site and facilities teams at buildings such as St Michael's Church of England Primary School, a drone or thermal camera can show a large roof in a single visit. If you own one of the older houses in the streets near Highgate United Reformed Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Highgate is about 2 miles north-east of Hampstead, in Greater London. If you are in Highgate, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Our area takes in places right across Greater London.

What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Which survey package you book
- Building height and the viewpoints available
- The type of building, from a house to a block or an office
- Extra roofs, like extensions, dormers or garages
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.
What we need to know
A few details help us suggest the right survey and price. When you contact us, tell us:
- How the loft is reached, if there is one
- Your postcode, so we can check access and travel
- Any stains, drips or damp patches you’ve seen indoors
- The kind of building and roof involved
Getting a price is simple: just phone 07833 053749 or drop us an email, tell us about the property and we will explain which survey suits. We confirm the price before anything is booked.
How it works
After the inspection, everything we found is written up in a report with photographs. On timing, most surveys take an hour or two for most homes, plus time to check any thermal findings with moisture readings. From the street, a London terrace normally shows only its front slope or parapet, so in Highgate we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- 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 we arrive
- For a flat or shared roof, check access with the freeholder or managing agent
- Make sure pets are kept safely away
- Clear the way to the loft hatch
Booking a survey

Useful tips for Highgate property owners
Here are a few things we’d tell any owner, before and after a survey:
- Keep the report to compare against after any repair
- Check outlets after heavy rain
- Keep the heating on as usual before a heat loss survey
- Note where damp appears and after what weather
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
Landlords, agents and block managers in Highgate
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, and they’re priced for the size.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
When to book a survey in Highgate
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, especially when it’s warm inside and cold outside.
Here are some of the things we see frequently:
- Possible trapped moisture under a flat roof covering
- Water getting in at parapets and stacks
- Missing or slipped insulation
- Leaks far from where the stain appears
If you look after a shop, office or commercial unit, for instance near The Mall Wood Green, large commercial roofs are often easiest to see from the air or with a thermal camera.
Before booking any roof surveyor

- Which limits apply to the survey
- How long they’ve been surveying roofs
- What the report includes, and whether it has photos

How the survey changes by roof type
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. Thermal images, checked with moisture readings, can help trace it.
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Questions from Highgate
Are there drone restrictions around Highgate?
The answer turns on the exact location and the conditions on the day. 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. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. Strong wind or a downpour also stops a small drone flying.
Is my home in Highgate listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
