Thermal roof survey in Morden: what you get
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. We back up the images with moisture readings and a careful look at the roof. The report is clear about what the images show and what they don’t. Where something can’t be confirmed, we say what would help next. We are often asked to look into damp around chimneys and parapets and damp patches with no obvious cause, on flat roofs, pitched roof slopes and loft conversions.
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. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

What we can’t see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- What’s inside walls or under coverings, without opening up
- Proving moisture from the images alone
- Readings unaffected by sun, shade or reflections
If in doubt, ring 07833 053749 or send us an email and we’ll suggest the right survey before booking. The full list of what we check.

What a survey costs
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- How many separate roofs there are, such as extensions, dormers and garages
- The package you choose: Basic, Standard or Premium
- Chimneys, valleys, parapets and other details
- The height of the building and how the roof can safely be seen
For a price for your roof in Morden, call 07833 053749 or use the contact form and let us know about the roof. The price is agreed before a date is set.
Getting in touch
When you call or email, these details help:
- Anything about access we should know
- When you need the report by
- Why you want a survey: buying, a leak, a storm or new work
- Pictures from the garden or a window, if you have them
Not sure which survey you need? The easiest way is to phone 07833 053749 or use the contact form and describe the roof and why you want it surveyed. We will explain the options and the price.
Airspace, weather and Morden roofs
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. Southside House, about 1.9 miles north-west, is one of the historic houses in the wider area around Morden. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church such as St Lawrence Church are frequently among the oldest in a place, and if you own one of the older houses nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image. For site and facilities teams at buildings like Morden Primary School, big roofs are where photos from the air and thermal images show the most at once.
Morden is about 2 miles south of Wimbledon, in Greater London. Surveys in Morden work the same way as everywhere we cover: a careful inspection, photos and a written report. Morden is one of the places in Greater London where we work for thermal roof surveys. You can also see our page for London.
Surveys in SM4, SM3 and SW20 work the same way as everywhere else we cover. If you need a thermal roof survey at a property on London Road, Epsom Road and Holne Chase or anywhere close by, we can help. Morden is on the B279, so it’s easy for us to get to. Other places close to Morden include Lower Morden (1 mile south-west), Sutton Common (1 mile south-east), North Cheam (2 miles south), Worcester Park (2 miles south-west) and Stoneleigh (3 miles south-west).

Common questions in Morden
Can you fly a drone over a roof in Morden?
That depends on where the roof is and on 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. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Can parking be tricky for a visit in Morden?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
What happens next?
You will get the report by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Does the report include photographs?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take between one and two hours for most houses, or half a day or so for a commercial building. The report is sent afterwards by email.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when booking.
What conditions are best for thermal imaging?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Signs you need a thermal roof survey in Morden
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Here are some of the things we see often:
- Thin or uneven insulation in the roof
- Possible trapped moisture under a flat roof covering
- Damp around roof outlets and upstands
- Damp patches with no obvious cause
For a London address like Morden, it helps to know about controlled parking before the day.
Before booking any roof surveyor
- What exactly goes into their report
- How long they’ve been surveying roofs
- What they will not be able to tell you
- Which viewpoints they use to see the roof
Why get it checked now?
Wet insulation under a flat roof does not dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there is time to plan.
Prices start from £400, including VAT. The final price depends on how big and how high the roof is, how it can be seen safely and the package you choose.

The survey, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. If you have questions on the day, just ask. In a London area like Morden, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from the ground, windows, the loft and, where it is safe, the roof itself.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- We take thermal images of the roof to pick up temperature patterns.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Note where any stains or damp appear
- Check pets are kept safely away
How to book
Booking is simple: just ring 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
Advice
Different roofs, different checks
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are frequently laid over insulation boards. Wet boards can show as temperature differences on the images.
