Thermal Roof Survey in North Sheen
Not sure what state the roof is in? You can book a thermal roof survey in North Sheen and across Greater London, with plain-English findings.
- Wet insulation beneath the membrane
- Damp around chimneys and parapets
- Areas losing heat at the eaves and junctions
How a thermal roof survey works in North Sheen
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, something you cannot usually tell from the surface. We then check those areas with moisture readings. If you’ve noticed areas losing heat at the eaves and junctions and areas of a flat roof that may hold water, we can find out what’s behind it, whatever the roof.
London’s roofs are frequently hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That’s 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 North Sheen as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
If any part of the roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

What affects the price in North Sheen
When we price a survey, we consider:
- How many separate roofs there are, like extensions, dormers and garages

- Basic, Standard or Premium
Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we’ll tell you which fits.
What to tell us when you contact us
We’ll usually ask about:
- Where the property is, with the postcode
- What kind of property and roof it is
- Any marks or damp showing indoors
- Any deadline, such as an exchange date
We confirm the price for your survey before you book, so you know the cost up front. Thermal roof survey starts from £400, including VAT. To book, ring 07833 053749 or send us an email.
Common roof problems in North Sheen
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
Typical things we’re asked to look at include:
- Stains that keep coming back
- Missing or slipped insulation
- Wet insulation beneath the membrane
- Patches of heat loss across the roof
For hotels and guest houses around North Sheen, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- What’s outside the scope of the survey
- What follow-up you get after the report
- What the report includes, and whether it has photographs

Useful tips for North Sheen property owners
Small things make a difference. Our tips:
- Do not climb onto the roof to look for leaks yourself
- Clear leaves from outlets and gutters each autumn
- Photograph damp patches with the date
- Keep the heating on as usual before a heat loss survey
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
Airspace, weather and North Sheen roofs
Within a mile and a half or so of North Sheen there are several hotels. For hotels and other commercial buildings, large roofs are where close-up aerial shots and thermal images show the most at once. North Sheen is about 2 miles from the edge of the flight restriction zone around London Heliport in Battersea. If the drone is used for your survey, the exact boundary is checked for the address first.
If you look after a shop, office or commercial unit, for instance near Livat Hammersmith, thermal images can show trapped moisture across a wide commercial roof. Anyone responsible for a site like Kew Riverside Primary School will know that big roofs are where photos from the air and thermal images show the most at once.

Why it’s worth a survey now in North Sheen
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Any roof job in North Sheen means planning around parking, neighbours and access. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.

Common questions in North Sheen
Are there drone restrictions around North Sheen?
It depends on the exact address and the weather on the day. North Sheen is about 2 miles from the edge of the flight restriction zone around London Heliport in Battersea. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. 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. The flight also waits for calm, dry weather, and the rest of the survey doesn’t depend on the drone.
How do I find out if my home in North Sheen is listed?
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.
What can thermal imaging tell me about my roof?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years, with 98% customer satisfaction.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so the building owner or managing agent needs to agree access. We can only inspect what we’re given access to.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. We look from the loft as well, where there is safe access.
How do I arrange a thermal roof survey in North Sheen?
Simply ring 07833 053749 or drop us an email. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
What happens on the day
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take about one to two hours at most homes, and longer for a large or complex roof. London terraces rarely offer a view of the whole roof from one spot, so in North Sheen we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s safe.
- 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.
Preparing for the visit
- Show us where any leaks or stains appear
- If the roof is shared, arrange access with whoever manages the building
- Have any questions written down, so nothing gets missed
