Thermal Roof Survey in Deptford
Thermal imaging to find moisture and heat loss patterns in a roof for Deptford and the rest of Greater London. Surveys run on weekdays and at weekends.
- Gaps in loft insulation
- Patches of heat loss across the roof
- Leaks that are hard to trace
What a thermal roof survey looks like in Deptford
The flight restriction zone around London City Airport comes within about 2 miles of Deptford. Where the drone is part of the survey, the exact boundary is checked for the address first. There are several hotels within about a mile and a half of Deptford, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, large roofs are where photos from the air and thermal images show the most at once.
If you look after a building such as Tidemill Academy, big roofs are where photos from the air and thermal images show the most at once. For businesses in and around places like Lewisham Shopping Centre, a commercial roof can be photographed from above without anyone walking on it.
Deptford is about 3 miles south-east of Whitechapel, in Greater London. Wherever you are in Deptford, we can carry out thermal roof surveys at your property, on a weekday, Saturday or Sunday. Deptford is one of the places in Greater London where we work for thermal roof surveys.

About our thermal roof survey in Deptford
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. The report is clear about what the images show and what they do not. Where something cannot be confirmed, we say what would help next. We survey commercial roofs, pitched roof slopes and insulated roof spaces, and common reasons people get in touch are thin or uneven insulation in the roof and possible trapped moisture under a flat roof covering.
London’s roofs are often hard to see from the street: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. Drone photos and thermal images can show parts of a roof that are hard to reach 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.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to.

How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. You’re welcome to ask questions while we are there. For a visit in Deptford, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, 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.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Check pets are kept safely away
- Show us where any leaks or stains appear
- Make a note of anything you’d like us to look at

Leave it or get it looked at?
Trapped water can harm decks, timbers and ceilings the longer it stays. Surveying sooner gives you more choice about what to do. In Deptford, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
Every price we give includes VAT. Our price is from £400, including VAT. You will know the price for the job before you book.

Different roofs, different checks
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
DIY checks: what’s safe
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.

When to book a survey in Deptford
People frequently book a thermal survey when a damp patch has no obvious cause. Water can travel under a roof covering or along timbers before it shows inside. Temperature patterns can help narrow down where to look.
Signs worth acting on include:
- Wet areas near outlets and upstands
- Areas of a flat roof that may hold water
- Cold areas below the roof
- Thin or uneven insulation in the roof
Historic houses such as Queen's House, about 1 mile east, show how far back building around Deptford goes. Close-up aerial shots and thermal images let an old roof be checked without anyone disturbing it.
Before booking anyone
- Whether the loft is part of the inspection
- Whether they hold professional indemnity and public liability insurance
- Which limits apply to the survey
- Their drone registration, if they fly one
What we cannot see
A survey is a careful look at the roof, but it can’t do everything. The main limits are:
- Whether the deck or roof structure is strong enough
- An energy rating for the building
- The condition of timbers we cannot see
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. The full list of what we check.

Deptford: your questions answered
Is drone flying allowed in Deptford?
That depends on where the roof is and on the weather. The flight restriction zone around London City Airport comes within about 2 miles of Deptford. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. 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. A small drone can’t fly safely in strong wind or heavy rain, though the rest of the survey goes ahead either way.
Is my home in Deptford listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Can a thermal camera see water?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
Will you walk on the roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where it applies. Anything we cannot see is noted in the report.
Do you work in Deptford?
Yes. We cover Deptford and the rest of Greater London. To book, phone 07833 053749 or email us.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
What happens next?
You’ll 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.
