Mortlake Thermal Roof Survey
We take a careful look at the roof at your property in Mortlake, and put it all in a report with photos.
- Leaks far from where the stain appears
- Thin or uneven insulation in the roof
- Damp that repairs haven’t cured
Why it is worth a survey now in Mortlake
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Any roof job in Mortlake means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
Why us?
- Professional indemnity and public liability insurance
- Photos and a written report every time
- An independent look at the roof
- Prices that include VAT

How a thermal roof survey works in Mortlake
A thermal survey isn’t a quick fix for every roof problem. 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. Our report says plainly what the camera picked up and how sure we can be. If a finding can’t be confirmed, the report suggests a next step. We survey flat roofs, commercial roofs and insulated roof spaces, and people most often book us about missing or slipped insulation and cold areas below the roof.
Flying in London takes more checking than most places: 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. Every address in Mortlake is checked before any drone flight, and where permission is needed, the flight waits for it.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

When to book a survey in Mortlake
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. A thermal survey, checked with moisture readings, can give a much clearer picture.
Look out for signs like these:
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
- Patches of heat loss across the roof
- Areas of a flat roof that may hold water
Mortlake is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
Choosing a roof surveyor
- Whether the loft space is looked at, where there is one
- Their insurance cover
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you can ask questions once you have the report
For landlords and managing agents
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Thermal roof surveys around Mortlake
Chiswick House, about 1.3 miles north, is one of the historic houses in the wider area around Mortlake. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. 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.
Shop and office owners around Putney Exchange may find that a commercial roof can be photographed from above without anyone walking on it. If you live in an older home near All Saints' Church, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Mortlake is about 3 miles west of Fulham, in Greater London. We survey roofs in Mortlake and the surrounding area as part of our work across London and South East England. Mortlake is one of the places in Greater London where we work for thermal roof surveys. We also survey roofs in London.
All of SW14, SW13 and SW15 is covered for thermal roof surveys. Whether your property is on Elm Road, Well Lane and Coval Road or a nearby road, we can help. Mortlake sits on or near the A3003. We also cover East Sheen (1 mile south-west), North Sheen (1 mile north-west), Barnes (1 mile north-east), Grove Park (1 mile north) and Roehampton (1 mile south-east). We also work in nearby towns like London (8 miles east), City of Westminster (6 miles north-east), Marylebone (6 miles north-east), Kensington (4 miles north-east), St Pancras (8 miles north-east) and Shoreditch (9 miles north-east).
What’s near Mortlake
Around Mortlake, our work takes us to homes and buildings near Richmond Park Academy, Hare and Hounds pub and Palewell Park, among other places. There is a railway station in Mortlake itself: Mortlake station. A little further out are Ubuntu Museum: African Museum of Humanity (1.1 miles south-east) and Barnes Hospital (less than half a mile east). Green spaces nearby include Richmond Hill and Kew Gardens Lake.
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes between one and two hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. If you have questions on the day, just ask. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- 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.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- Move anything stored under the loft hatch
- Buyers: confirm access with the estate agent or seller
- For flats, check roof access has been agreed

Useful tips for Mortlake property owners
There is plenty you can do without going near the roof. Here’s what helps most:
- Talk to us about the weather when booking
- Use the report as a baseline for later checks
- Keep a record of when stains appear
- Move stored items away from the loft hatch
Where a pattern can’t be confirmed, the report says what could help, for example electronic leak detection or a roofer opening up a small section.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the roof space.

Common questions in Mortlake
Is drone flying allowed in Mortlake?
It depends on the exact address and the weather on the day. Mortlake is about 2 miles from the edge of the flight restriction zone around London Heliport in Battersea. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. 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. Each address is checked against all of them before the drone goes up. The flight also waits for calm, dry weather.
Can parking be tricky for a visit in Mortlake?
It can be, so it is useful to let us know about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How long does the survey take?
Expect it to take roughly 1–2 hours for a house; commercial roofs usually need 3–4 hours. The written report follows by email, on the timescale of your package.
How do I arrange a thermal roof survey in Mortlake?
The quickest way is to ring 07833 053749 or send us an email. Let us know the address and a little about the roof. Surveys run on weekdays and at weekends.
Do you climb onto every roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. Anything we cannot see is noted in the report.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it is warm inside and cold outside. Where we can reach the loft safely, we check there too.
How the survey changes by roof type
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We check cracks by eye and use the images to see whether there is a pattern around them.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Reflections from shiny surfaces can affect readings, which we allow for.
