About our thermal roof survey in West Barnes
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging frequently helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. Common reasons to book are cold areas below the roof and damp that repairs haven’t cured, across flat roofs, commercial roofs and insulated roof spaces.
Many London roofs are hidden from the pavement: valley gutters behind parapets, dormers and flat-roofed rear 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. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what is not.

What we look for on each type of roof
Loft insulation
In the roof space, the camera can pick up gaps and thin areas of insulation. We inspect the loft where it can be reached safely.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.

Checking the roof from ground level
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Thermal roof surveys in West Barnes: local notes
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help. Historic houses such as Southside House, about 1.1 miles north, show how far back building in the area around West Barnes 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.
Parking in West Barnes, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway as you book, as a space near the door cannot be promised. For an older house near a landmark such as Holy Cross, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from the air or with a thermal camera helps. If you look after a building such as Sacred Heart Catholic Primary School, big roofs are where aerial photos and thermal images show the most at once.

Tips that help
You don’t need to be a roofer to help. Here’s what helps most:
- Ask us about the forecast if rain is expected
- Use the report as a baseline for later checks
- Let us know where and when you’ve seen damp or stains
- Clear leaves from outlets and gutters each autumn
Buyers can use the findings when talking to the seller or agent. What you do with it is up to you, whether that is asking for work or discussing the price.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
What a survey costs
We confirm the price for your survey before you book. These are the things that affect it:
- The size of the roof
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400. We confirm the exact price before booking.
Getting in touch
A little information up front helps. It helps to include:
- How the loft is reached, if there is one
- Where any leaks, stains or damp patches show inside
- The property’s address and postcode
- Pictures from the garden or a window, if you have them
If you have photos of the roof, send them over. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, phone 07833 053749 or email us.
Leave it or get it looked at?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Every price we give includes VAT. Our price is from £400, including VAT. You will know the price for the job before booking.

What happens on the day
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Have any paperwork from past roof work to hand
- Keep pets in another room
- Make a note of anything you’d like us to look at
Getting a price
A quick phone call is normally the easiest start: ring 07833 053749 or send us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
Advice
West Barnes: your questions answered
Are there drone restrictions around West Barnes?
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, including zones around airports and prisons. A small drone can’t fly safely in high wind or heavy rain, though the rest of the survey goes ahead either way.
Is parking a problem for a survey in West Barnes?
Sometimes, yes. If West Barnes has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Do you climb onto every roof?
Only where it is safe to do so. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
What does the report include?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
What do I do with the report?
You’ll get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
How long will you be at the property?
Expect it to take between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The written report follows by email, on the timescale of your package.
Is this a RICS 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.
