Thermal imaging roof survey in Winchmore Hill, Greater London
Find out the condition of the roof at your property in Winchmore Hill from an independent roof surveyor. Visits run on weekdays and weekends, in the daytime.
- Patches of heat loss across the roof
- Leaks that are hard to trace
- Cold spots on ceilings under the roof
Leave it or get it looked at?
For buyers, a thermal survey adds detail that a visual inspection cannot give. Hidden problems found before exchange can be raised with the seller or agent. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is often older than it looks.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
Why us?
- An independent look at the roof
- Plain-English reports with photos
- Surveys seven days a week
- Professional indemnity and public liability insurance

Thermal roof surveys for homes and businesses in Winchmore Hill
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. The report shows the images and explains what they may mean. We do not give energy ratings or heat loss calculations. We survey ceilings below the roof, pitched roof slopes and commercial roofs, and common reasons people get in touch are damp where roofs meet walls and chimneys and areas of a flat roof that may hold water.
Many London roofs are hidden from the pavement: valley gutters behind parapets, dormers and flat-roofed rear additions. That is where a view from the air or a thermal camera helps, by showing what can’t be reached safely. The weather decides the day: both drones and thermal cameras need the right conditions. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Common questions in Winchmore Hill
Will parking be an issue for a roof survey in Winchmore Hill?
Normally it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Are there drone restrictions around Winchmore Hill?
Typically 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. 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, and the rest of the survey doesn’t depend on the drone.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Does thermal imaging work on slate and tile roofs?
It can be useful, though pitched roofs are usually harder to read. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it is safe.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Common roof problems in Winchmore Hill
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
Look out for signs like these:
- Damp that repairs haven’t cured
- Gaps in loft insulation
- Areas losing heat at the eaves and junctions
- Cold spots on ceilings under the roof
Take an older house close to Holy Trinity: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
What to check before booking
- How they plan to inspect the roof safely
- How much experience they have with roofs like yours
- Their report turnaround times
- What happens after the report arrives
How we price thermal roof surveys
When we price a survey, we consider:
- Height and safe access
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether you choose the Basic, Standard or Premium Survey
- Any need for thermal images or a drone flight
Prices quoted always include VAT, and the written report is part of the package. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.
Booking your survey
To price your survey accurately, we will ask about:
- Where water is showing inside, if it is
- Access details, such as a loft hatch or a shared roof
- Pictures of the roof from a safe spot, if you have them
- Where the property is, with the postcode
Once you know what you need, call 07833 053749 or email us. From there it’s a case of choosing a package, agreeing the price and fixing a day.
Thermal roof surveys in Winchmore Hill: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place. The wider area around Winchmore Hill has a long history of building, with Bruce Castle about 2.6 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
Shop and office owners around Edmonton Green Shopping Centre may find that thermal images can show trapped moisture across a wide commercial roof. For a London address like Winchmore Hill, it helps to know about controlled parking before the day, along with any off-street space.

How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two for most houses, and more on a big or complicated roof. In Winchmore Hill, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Let us know where we can park nearby
- Make sure the loft hatch can be reached
- Have any questions written down, so nothing gets missed

Useful tips for Winchmore Hill property owners
There’s plenty you can do without going near the roof. What helps most:
- Heat the home normally on the days before
- Keep dated photos of any marks on ceilings
- Clear leaves from outlets and gutters each autumn
- Remember the conditions on the day affect the results
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Consider a repeat survey after major work on the roof, when the conditions are suitable.
How the survey changes by roof type
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
