About our thermal roof survey in Blackwall
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It is important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you are worried about leaks that are hard to trace and heat escaping through the roof, a survey will tell you what’s going on.
London’s roofs are frequently hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That’s where a view from the air or a thermal camera helps, by showing what can’t be reached safely. Weather on the day decides whether it goes ahead, in Blackwall as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the roof, any defects and our written recommendations.

What we do, step by step
The aim of the visit is simple: to see as much of the roof as can safely be seen and record it clearly. Notes and photographs go into the written report. The visit typically takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Blackwall moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- 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.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- If it is not your property yet, arrange access through the agent
- Find any records of previous roof work
- Clear the way to the loft hatch
Booking a survey
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or send us an email when you’re ready.

Thermal roof surveys around Blackwall
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail. Blackwall is about 1 mile from the restricted area over the Isle of Dogs, where drone flights need permission from NATS. If the drone is used for your survey, the address is checked against it before any flight.
For a London address like Blackwall, it’s useful to know about controlled parking before the day. Take a building like Woolmore Primary School: a view from above covers a wide roof far faster than walking it.
Blackwall is about 1 mile south-west of Canning Town, in Greater London. Anywhere in Blackwall, we can come and survey your property. Blackwall is one of the towns and villages in Greater London where we work for thermal roof surveys.
Surveys in E14, SE10 and E16 work the same way as everywhere else we cover. Whether your property is on Nutmeg Lane, Athol Square and Leamouth Road or anywhere close by, we can survey it. With the A102 and A1206 close by, Blackwall is simple for us to get to for thermal roof surveys. Nearby, we also carry out thermal roof surveys in Coldharbour (1 mile south-west), Leamouth (1 mile north-east), Limmo Peninsula (1 mile north-east), Poplar (1 mile west) and London Docklands (1 mile west). Within a short drive, we also cover London (4 miles west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (9 miles west), St Pancras (5 miles west) and Shoreditch (3 miles north-west).
Landmarks near Blackwall
In Blackwall, that means homes and buildings near The Gun pub, Tower Hamlets College and Bow Creek Ecology Park. Blackwall’s nearest station is Canary Wharf station, roughly 0.6 miles west. Nearby you will also find Poplar Hospital (under half a mile north-west) and London Gas Museum (1.1 miles north). Green spaces nearby include Lavender Pond and Tower Hill.
Before and after the survey
Small things make a difference. Some pointers:
- Take photos of stains as they appear, so we can compare
- Do not climb onto the roof to look for leaks yourself
- Keep the heating on as usual before a heat loss survey
- Check the loft can be reached safely
Premium Surveys include an in-person consultation, so you can go through the images with us. There’s a 12-month follow-up too.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
What we can’t see
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Whether the deck or roof structure is strong enough
- Proving moisture from the images alone
- Reliable images in rain, strong wind or on a wet roof surface
If in doubt, ring 07833 053749 or drop us an email and we’ll point you to the right survey. What a survey covers and doesn’t.

Do you need a thermal roof survey in Blackwall?
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
Look out for signs like these:
- Gaps in loft insulation
- Water getting in at parapets and stacks
- Moisture around outlets and upstands
- Heat escaping through the roof
If you run a hotel or guest house in or near Blackwall, a roof problem can mean rooms out of use, so it pays to find faults before guests do.
Before you book any roof surveyor
- Whether VAT is in the quoted price
- What’s outside the scope of the survey
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How much experience they have with roofs like yours
How the survey changes by roof type
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. It focuses the survey on the areas that matter.
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. The camera can help show damp around these junctions.

Blackwall: your questions answered
Are there drone restrictions around Blackwall?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around London City Airport covers Blackwall, or comes right up to its edge. We ask the airport for permission before flying there, and only fly if it’s given. The restricted area over the Isle of Dogs, where drone flights need permission from NATS, is about 1 mile from Blackwall. If a roof falls inside it, we apply for permission before flying, and the flight only goes ahead if it’s granted. 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, though the rest of the survey goes ahead either way.
Is parking a problem for a survey in Blackwall?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
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.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Is thermal imaging useful on pitched roofs?
It can be useful, though pitched roofs are usually harder to read. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it is safe.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
