About our thermal roof survey in Carshalton
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. The camera does not see water itself, so we check what it shows with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We survey pitched roof slopes, insulated roof spaces and ceilings below the roof, and the problems we are asked to look at most are wet insulation beneath the membrane and heat escaping through the roof.
Many London roofs are hidden from the pavement: 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. Weather on the day decides whether it goes ahead, in Carshalton as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

Why get it checked now?
Wet insulation under a flat roof does not dry out on its own while the covering stays on. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Every price we give includes VAT, and the report isn’t charged as an extra. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Carshalton questions
Is parking a problem for a survey in Carshalton?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Does a conservation area affect roof work in Carshalton?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Which days do you carry out surveys?
Surveys run on any day of the week. To find a day that suits you, ring 07833 053749 or drop us an email.
How long will you be at the property?
It typically takes about one to two hours on an ordinary house, while a commercial roof takes nearer three to four hours. You will then get the report by email, on the timescale of your package.
Will thermal imaging find my leak?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. If the source can’t be confirmed, we’ll say what could help next, like electronic leak detection.
How the survey works
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when booking.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- 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.
How to prepare
- Clear the way to the loft hatch
- Tell us about parking before the day
- Have keys ready for side gates, garages or roof access doors

Related advice
For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant in advance.
Practical tips
A little preparation and a few simple habits help. Our tips:
- Clear leaves from outlets and gutters each autumn
- Note where damp appears and after what weather
- Don’t climb onto the roof to look for leaks yourself
- Remember the conditions on the day affect the results
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.
Roof by roof
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. The camera can help show where to look.
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.

Airspace, weather and Carshalton roofs
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
If you look after a shop, office or commercial unit, for instance near Centrale Croydon, big, flat commercial roofs are where close-up aerial shots and thermal images help most. For site and facilities teams at buildings such as Carshalton High School for Girls, thermal images can show where wet insulation sits under a big flat roof. For a London address like Carshalton, it helps to know about controlled parking before the day.
