Thermal imaging roof survey in Lower Morden, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof for Lower Morden, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Damp around roof outlets and upstands
- Damp where roofs meet walls and chimneys
- Water that travels before it shows
How a thermal roof survey works in Lower Morden
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. It is important to know that the camera shows temperature, not water, 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. If you’re worried about areas of a flat roof that may hold water and missing or slipped insulation, a survey will tell you what’s going on, on ceilings below the roof, pitched roof slopes and commercial roofs alike.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Before a drone goes up in Lower Morden, the address is checked against all of them, and where permission is needed, the flight waits for it.
Where we can’t see part of the roof, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

When you need someone else
A survey is a careful look at the roof, but it cannot do everything. Its limits include:
- A formal energy assessment
- Reliable images in rain, strong wind or on a wet roof surface
- Hidden layers that need to be opened up to check

Drones, thermal imaging and Lower Morden roofs
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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
As a London address, Lower Morden can be tricky for parking: a visitor permit or a nearby bay makes the day easier. Historic houses such as Southside House, about 2 miles north, show how far back building around Lower Morden goes. Older roofs nearby can be steep and hard to see from the ground, and a survey from above or with a thermal imager does not touch the roof itself.
Lower Morden is about 2 miles north-west of Sutton, in Greater London. We survey roofs in Lower Morden across London and South East England. Our area takes in places right across Greater London, from the larger towns to small villages. London is in our area too.
We cover every part of the SM4, SM3 and KT4 postcode area for thermal roof surveys and the streets around it. If you need a thermal roof survey at a property on Ash Road, Bow Lane and Garth Road or a nearby road, we can survey it. Other places close to Lower Morden include Morden (1 mile north-east), Sutton Common (1 mile east), North Cheam (1 mile south), Worcester Park (2 miles south-west) and Stoneleigh (2 miles south-west). Further out, we also cover London (9 miles north-east), City of Westminster (9 miles north), Marylebone (9 miles north), Kensington (8 miles north), St Pancras (10 miles north-east) and Shoreditch (11 miles north-east).

Signs you need a thermal roof survey in Lower Morden
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when it’s warm inside and cold outside.
Look out for signs like these:
- Ceilings that feel colder in places
- Heat escaping through the roof
- Damp where roofs meet walls and chimneys
- Damp patches with no obvious cause
Take a building like Aragon Primary School: thermal images can show where wet insulation sits under a big flat roof.
Before you book any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What follow-up you get after the report
- Whether they hold professional indemnity and public liability insurance
- Whether the inside of the roof is included
Useful tips for Lower Morden property owners
You do not need to be a roofer to help. What helps most:
- Clear a path to the loft hatch before we arrive
- Use the report as a baseline for later checks
- Leave the roof to people with safe access
- Talk to us about the weather when booking
Where a pattern can’t be confirmed, the report says what could help, like electronic leak detection or opening up a small area.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.

Loft insulation
The difference is clearest when the home is heated and it is cold out. We explain in the report how the conditions on the day affected what we saw.
FAQs for Lower Morden
Are there drone restrictions around Lower Morden?
It depends on the exact address and the weather on the day. 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, and the rest of the survey does not depend on the drone.
Will parking be an issue for a roof survey in Lower Morden?
Sometimes, yes. If Lower Morden has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
What conditions are best for thermal imaging?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. Our report notes the conditions and how they affected the findings.
Can you use a thermal camera on a sloping roof?
It can help, but the results are frequently less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there is safe access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
What happens next?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Leave it or get it looked at?
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. That helps you and your roofer decide what really needs replacing. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

What we do, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photographs as we go and record our findings for the written report. It usually takes about 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. In Lower Morden, as in much of London, lots of properties are flats or terraces without 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 booking.
- First we discuss the roof, any damp and the forecast for the visit.
- 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
- If you are buying, let the agent know when we are coming
- Clear the way to the loft hatch
- Tell us where we can park nearby
