Thermal roof surveys for homes and businesses in Marylebone
We present each thermal image next to a normal photo of the same area, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. You can talk the findings through with us at the in-person consultation. There is a 12-month follow-up as well. Common reasons to book are wet areas near outlets and upstands and possible trapped moisture under a flat roof covering, on insulated roof spaces, pitched roof slopes and loft conversions.
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. Weather on the day decides whether it goes ahead, in Marylebone as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take about one to two hours for most homes, plus time to check any thermal findings with moisture readings. In a London area like Marylebone, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can be seen safely from the ground, windows, the loft and, where it’s safe, the roof itself.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Before the survey
- Check pets are kept safely away
- Make a note of anything you’d like us to look at
- If it is not your property yet, arrange access through the agent

Surveys for landlords and agents in Marylebone
We survey roofs for landlords and agents as well as householders. A report with photos gives you a clear record of the roof, which helps you plan work between tenancies.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
Why get it checked now?
For buyers, a thermal survey adds detail that a visual inspection can’t give. Hidden problems found before exchange can be raised with the seller or agent. In Marylebone, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we will tell you which fits.
Why book with us

What a thermal roof survey looks like in Marylebone
Marylebone has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a large roof can be surveyed without guests having anyone working above them. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place.
If you live in an older home near Russian chapel on Welbeck Street, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Hotels and guest houses near Marylebone cannot easily close rooms for a leak. Take a building like St Vincent's Catholic Primary School: big roofs are where aerial photos and thermal images show the most at once.
Marylebone is about 3 miles north-west of London, in Greater London. Houses, flats, blocks and commercial buildings in Marylebone can all book thermal roof surveys. Our Greater London coverage includes Marylebone and the places around it.
We cover every part of W1U, W1T and W1K for thermal roof surveys and the streets around it. If you need a thermal roof survey at a property on Park Lane, Duck Lane and Bruton Lane or a nearby road, we can help. Marylebone sits on or near the A400 and A401, which makes travel easy. Nearby, we also carry out thermal roof surveys in City of Westminster (1 mile south-west), Mayfair (1 mile south), Fitzrovia (1 mile north-east), Burlington Estate (1 mile south-east) and Soho (1 mile south-east). Within a short drive, we also cover London (3 miles south-east), Kensington (3 miles south-west), Shoreditch (3 miles east), Walthamstow (7 miles north-east), Hoxton (3 miles north-east) and Whitechapel (3 miles east).

Nearby too are The St Marylebone CofE School (under half a mile north-west) and The Phoenix pub (under half a mile south-east). There’s a railway station in Marylebone itself: Bond Street station.

The countryside around Marylebone includes Adelaide Nature Reserve and St. James's Park Lake.
Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Marylebone questions
Will parking be an issue for a roof survey in Marylebone?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Are there drone restrictions around Marylebone?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around London Heliport in Battersea comes within about 2 miles of Marylebone. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. Marylebone is about 2 miles from the restricted area over Hyde Park, where drone flights need permission from NATS. We check whether the address falls inside it, and if it does we apply for permission, which is not always given. 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. Strong wind or a downpour also stops a small drone flying.
Will thermal imaging find my leak?
It often helps show where to look. Patterns can suggest where trapped water has spread. We combine it with a visual inspection and moisture readings because the camera cannot confirm water on its own.
Do you cover Marylebone?
Yes. Our area covers London and South East England, Marylebone included.
Is thermal imaging included in your surveys?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
What happens next?
You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
What conditions are best for thermal imaging?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Talk to us about the weather when booking
- Check from ground level or a window, never by climbing
- Let us know where and when you’ve seen damp or stains
- File the images with your roof records
We note the weather and surface conditions, and how they may have affected the results. That way you know how much weight to give each finding.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
