Thermal roof survey in New Malden: what you get
Your report sets out the thermal images alongside ordinary photographs, 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. If you have questions, the in-person consultation gives you time to go through them. A follow-up 12 months later is included too. We survey loft conversions, flat roofs and pitched roof slopes, and people most often book us about leaks that are hard to trace and damp around chimneys and parapets.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. Images are taken to show the roof we are surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building as you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photograph. You’ll see the good as well as the bad.

What we look for on each type of roof
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. We use the camera and moisture readings to help follow it.
Loft insulation
Heat loss shows most clearly when it is warm inside and colder outside. Our report notes how the conditions affected the images.

How we price thermal roof surveys
We confirm the exact price before booking. This is what makes a difference:
- Basic, Standard or Premium
- Features like valleys, chimneys, dormers and parapets
- The type of building, from a house to a block or an office
- How big the roof is
For a price for your roof in New Malden, ring 07833 053749 or email us with the address and some details. We will confirm the figure before booking.
What we need to know
We will normally ask about:
- Why you want a survey: buying, a leak, a storm or new work
- The property’s address and postcode
- How the loft is reached, if there is one
- The style of property, from a terrace to a block
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or drop us an email.
Useful tips for New Malden property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Keep outlets and gutters clear to stop water sitting
- Talk to us about the weather when booking
- File the images with your roof records
- Keep the heating on as usual before a heat loss survey
If the images suggest moisture that cannot be confirmed, we’ll say what would help next, for example electronic leak detection or a roofer opening up a small section.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
How the survey works
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect about one to two hours for most homes, plus time to check any thermal findings with moisture readings. London terraces rarely offer a view of the whole roof from one spot, so a visit in New Malden 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 go through the roof, the problem and the weather expected on the day.
- 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 we arrive
- Keep pets inside or away from the areas we’re looking at
- Dig out any old roof reports or invoices
- Unlock side gates and any roof access doors
Arrange a survey
Once you know what you need, ring 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.

Thermal roof surveys in New Malden: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. 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. Historic houses such as Southside House, about 1.6 miles north-east, show how far back building in the area around New Malden goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
For a London address like New Malden, it helps to know about controlled parking before the day, along with any off-street space. If you run a business near Bentall Centre, big, flat commercial roofs are where aerial photos and thermal images help most. The streets around a church such as New Malden Baptist Church are often among the oldest in a place, and if you own one of the older houses nearby, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.

FAQs for New Malden
Is drone flying allowed in New Malden?
Normally it comes down to two things: the airspace at the address and the weather. 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. Each address is checked against all of them before the drone goes up. Every flight is checked against the Drone Safety Map first. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
Can parking be tricky for a visit in New Malden?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Can a thermal survey trace a roof leak?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. Where it cannot be pinned down, the report suggests a next step, such as electronic leak detection.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Is thermal imaging useful on pitched roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
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 is the visit?
Time on site depends on the roof, but most surveys take an hour or two for most homes, plus time to check any thermal findings with moisture readings. The report is sent afterwards by email.
