Thermal roof survey in North Cheam: what you get
Thermal imaging is part of our Premium Survey, which starts from £400. It also includes a drone inspection where it applies, a structural analysis and a same-day report. There’s an in-person consultation as well, plus a follow-up 12 months later. To book, just ring 07833 053749 or send us an email with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. We survey commercial roofs, flat roofs and loft conversions, and people most often book us about missing or slipped insulation and leaks far from where the stain appears.
London’s roofs are often hard to see from the street: butterfly roofs behind parapets, dormer tops and flat roofs over back 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. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

North Cheam: your questions answered
Can parking be tricky for a visit in North Cheam?
It depends on the street. If North Cheam has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Are there drone restrictions around North Cheam?
Normally it comes down to two things: the airspace at the address and the weather. 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. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. Strong wind or heavy rain also stops a small drone flying, and the rest of the survey doesn’t depend on the drone.
Is thermal imaging good for finding leaks?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings because the camera cannot confirm water on its own.
How long will you be at the property?
Most surveys take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. The report follows by email.
Can a thermal camera see water?
The camera doesn’t see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
What do I do with the report?
You will get the report by email, with photographs and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Thermal roof surveys in North Cheam: local notes
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
North Cheam is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door cannot be promised. For site and facilities teams at buildings such as Cheam Park Farm Primary Academy, big roofs are where aerial photos and thermal images show the most at once.
North Cheam is about 3 miles north-east of Epsom, in Greater London. North Cheam is one of many places we visit across Greater London, for houses, flats and commercial buildings. Our area takes in places right across Greater London, from the larger towns to small villages. London is in our area too.
Here we cover the SM3, KT4 and SM1 postcode area for thermal roof surveys. That includes homes and businesses on Glyn Road, Covey Road and Lloyd Road and the roads around them. We also cover Cuddington (1 mile south-west), Lower Morden (1 mile north), Sutton Common (1 mile north-east), Stoneleigh (1 mile south-west) and Morden (2 miles north). We also work in nearby towns like London (10 miles north-east), City of Westminster (10 miles north), Marylebone (11 miles north), Kensington (9 miles north), St Pancras (12 miles north) and Shoreditch (12 miles north-east).
Local landmarks in North Cheam
Around North Cheam, our work takes us to homes and buildings near The Nonsuch Inn, Sutton College of Learning for Adults and Nonsuch Park and the streets around them. The nearest railway station is West Sutton station, about 0.8 miles south-east of the centre. Well-known places in the area include Chessington Castle Hill (3.2 miles west) and St. Anthony's Hospital (0.6 miles north). For a walk, there is Henman Hill and Derwent Floodwash.
What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes about one to two hours at a typical home, and longer for a large or complex roof. Many London properties are flats or terraces with no 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 you book.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- 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.
Preparing for the visit
- Keep pets out of the way during the survey
- Tell us about any leaks, stains or damp patches you know of
- Move anything stored under the loft hatch

Advice
How the survey changes by roof type
Parapets, valleys and junctions
Problems where roof slopes and walls meet are often hidden. We combine a close visual check with the thermal images.
Pitched slate and tile roofs
Slate and tile roofs are often harder to read with a thermal camera, because of the air space beneath. We combine the images with an inspection from the loft where there is safe access.
What we are asked to look at in North Cheam
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.
A survey can pick up problems such as:
- Wet areas near outlets and upstands
- Damp where roofs meet walls and chimneys
- Damp patches with no obvious cause
- Areas of a flat roof that may hold water
Nonsuch Mansion lies about 1 mile south, so building around North Cheam goes back a long way. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager does not touch the roof itself.

Checking the roof from the ground
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What a survey costs
A few things affect what a survey costs:
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- Whether you choose the Basic, Standard or Premium Survey
- Whether thermal imaging or a drone is needed
Our price is from £400, including VAT. The final price depends on how big and how high the roof is, how it can safely be seen and the package you choose.
What to let us know when you get in touch
Here’s what helps us most when you contact us:
- Pictures from the garden or a window, if you have them
- What’s prompted the survey
- Where any leaks, stains or damp patches show inside
- Where the property is, with the postcode
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or send us an email.
Honest limits
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- Insulation values or heat loss calculations
- Proving moisture from the images alone
- Hidden layers that need to be opened up to check
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey before booking. What a survey covers and doesn’t.
