Thermal roof survey in Cheam
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. You can ring 07833 053749 or drop us an email with the address and a note of what you’ve noticed. For big commercial roofs, we quote on size and access. Typical surveys look at patches of heat loss across the roof and wet insulation beneath the membrane, on loft conversions, flat roofs and insulated roof spaces.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. Images are taken to show the roof we are surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What a thermal roof survey does not cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Seeing water directly, as the camera shows temperature, not moisture
- The condition of timbers we cannot see
- Whether the deck or roof structure is strong enough
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before you book. What a survey covers and doesn’t.
Roof types and parts we check
- Flat roofs
- Loft conversions
- Pitched roof slopes
- Insulated roof spaces
- Commercial roofs
- Ceilings below the roof
What we look for on each type of roof
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. We check those patches with moisture readings.
Pitched slate and tile roofs
Inside the roof space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
What affects the price in Cheam
A few things affect what a survey costs:
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- House, block, shop or office
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We’ll give you the figure before anything is booked.
Booking your survey
When you call or email, these details help:
- Where water is showing inside, if it is
- The property’s address and postcode
- The reason for the survey, like buying, a leak or storm damage
- Access details, like a loft hatch or a shared roof
To get a price for thermal roof surveys in Cheam, call 07833 053749 or drop us an email. The address, the type of property and what you need to know help us give you an accurate price.
Surveys for landlords and agents in Cheam
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, so they’re priced to suit.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when booking and we will plan the visit with that in mind.
Common roof problems in Cheam
Once a leak has been fixed, people frequently ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain, given suitable conditions on the day.
We are frequently asked to look at:
- Areas of a flat roof that may hold water
- Patches of heat loss across the roof
- Water that travels before it shows
- Stains that keep coming back
If yours is one of the older homes in the streets near Church of St Andrew, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Choosing a roof surveyor
- How long the report takes to arrive
- How much experience they have with roofs like yours
- Which parts of the roof they’ll actually see
- Whether the loft is part of the inspection

What else we do in Cheam
Cheam: your questions answered
Will parking be an issue for a roof survey in Cheam?
Usually it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Is my home in Cheam listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Can you inspect my roof with a drone?
Yes, where applicable and safe. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). It is included in the Drone Roof Survey and, where applicable, the Premium Survey.
Will the survey show heat loss through my roof?
Thermal images can suggest where heat is escaping and where insulation may be missing. The survey isn’t an energy rating or a heat loss calculation, but the images show where improvements may help.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
Will I get photos?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Let us know about it when booking and we will explain what’s needed.
Airspace, weather and Cheam roofs
Nonsuch Mansion, about 1 mile north-west, is one of the historic houses in the wider area around Cheam. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help.
Shop and office owners around The Ashley Centre may find that a commercial roof can be photographed from above without anyone walking on it. For site and facilities teams at buildings such as Glaisdale School, a view from above covers a wide roof far faster than walking it.
Cheam is about 1 mile south-west of Sutton, in Greater London. In Cheam, as across Greater London, every roof gets the same careful survey. We cover towns and villages across Greater London, from the larger towns to small villages. You can also see our page for London.
All of SM2, SM3 and SM1 is covered for thermal roof surveys, from the main roads to the quietest streets. We cover properties on Wray Road, York Road and The Avenue. Close by, we survey roofs in Belmont (1 mile south-east), Cuddington (1 mile north-west), North Looe (1 mile south-west), North Cheam (2 miles north) and Nork (2 miles south). Larger places within reach include London (12 miles north-east), City of Westminster (12 miles north), Marylebone (12 miles north), Kensington (11 miles north), St Pancras (13 miles north) and Shoreditch (14 miles north-east).
Near you in Cheam
We work in homes and buildings around Avenue Primary Academy, Howell Hill and Overton Grange School and the streets around them. The closest station to Cheam is Cheam station, about 0.6 miles north of the centre. A little further out are The Ashley Centre (2.7 miles south-west) and Chessington Castle Hill (3.5 miles west). For a walk, there’s Duppas Hill and Belmont Pastures.
What we do, step by step
Every roof is different; as a rough guide, the survey takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. You’re welcome to ask questions while we are there. London terraces rarely offer a view of the whole roof from one spot, so a visit in Cheam moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- 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.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Have keys ready for side gates, garages or roof access doors
- Find any records of previous roof work
- Jot down any questions you want answered
