Thermal roof surveys for homes and businesses in St John's Wood
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves frequently show up as temperature differences. 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 don’t give energy ratings or heat loss calculations. We survey insulated roof spaces, ceilings below the roof and commercial roofs, and the problems we are asked to look at most are gaps in loft insulation and damp around roof outlets and upstands.
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 cannot be reached safely. Weather on the day decides whether it goes ahead, in St John's Wood as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Honest limits
A survey is a close look at the roof, but it can’t do everything. Its limits include:
- Structural calculations, which need a structural engineer
- Clear results when the conditions on the day are poor
- Confirming water without moisture readings

FAQs for St John's Wood
Can you fly a drone over a roof in St John's Wood?
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, including zones around airports and prisons. A small drone cannot fly safely in strong wind or heavy rain, though the rest of the survey goes ahead either way.
Can parking be tricky for a visit in St John's Wood?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
What happens after the survey?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you take photos of the roof?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
How fast do I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Can a thermal camera see water?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
Why get it checked now?
For buyers, a thermal survey adds detail that a visual inspection can’t give. Finding hidden moisture before exchange gives you facts to raise with the seller. In St John's Wood, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
Our price is from £400, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.
What you get with us
- Satisfaction rate of 98%

Different roofs, different checks
Felt and asphalt flat roofs
Felt and asphalt roofs frequently show wet areas as patches that differ from the rest. Moisture readings are used to check them.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.

What a thermal roof survey looks like in St John's Wood
About 0.6 miles south-east lies Winfield House, a reminder of how long the area around St John's Wood has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
For hotels and guest houses around St John's Wood, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. If you look after a shop, office or commercial unit, for instance near O2 Centre, a commercial roof can be photographed from above without anyone walking on it.

What we do, step by step
We will ask a few questions first, such as when any problem began and what work has been done before. The inspection then takes between one and two hours at most homes, and more on a big or complicated roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in St John's Wood moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. 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.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Getting ready for the survey
- Check the loft hatch can be reached
- Keep pets out of the way during the survey
- Let us know where we can park nearby
Getting a price
Our price is from £400, including VAT. The exact figure depends on the roof and the package, and you can phone 07833 053749 or use the contact form to find out.

Practical tips
You don’t need to be a roofer to help. Here’s what helps most:
- Don’t switch the heating off ahead of the visit
- Keep dated photos of any marks on ceilings
- Move stored items away from the loft hatch
- Clear leaves from outlets and gutters each autumn
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There’s a 12-month follow-up too.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.
Signs you need a thermal roof survey in St John's Wood
Some buyers want extra detail before they commit to a purchase. A Premium Survey adds thermal imaging, a drone inspection where applicable and a same-day report, which helps when timescales are tight.
Signs worth acting on include:
- Ceilings that feel colder in places
- Wet insulation beneath the membrane
- Leaks far from where the stain appears
- Patches of heat loss across the roof
If you own one of the older houses in the streets near Church of All Souls, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view by drone or thermal camera helps.
