Thermal roof survey in Welling
A thermal camera can help when the cause of damp isn’t obvious. Leaks often run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. We survey commercial roofs, pitched roof slopes and ceilings below the roof, and the problems we’re asked to look at most are wet insulation beneath the membrane and damp where roofs meet walls and chimneys.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. We take care to focus on the roof we’ve been asked to look at, in Welling as anywhere. Tell us about the building and access when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Where we cannot see part of the roof, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Airspace, weather and Welling roofs
Welling is about 2 miles from the edge of the flight restriction zone around London City Airport. If your survey includes the drone, we check the exact boundary for the address before flying. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
Danson House, about 0.4 miles south-east, is one of the historic houses in the wider area around Welling. A drone or thermal survey does not involve any work on the roof, which suits older buildings. If you run a business near Broadway Shopping Centre, big, flat commercial roofs are where aerial photos and thermal images help most.
Welling is about 9 miles east of London, in Greater London. Anywhere in Welling, we can carry out thermal roof surveys at your property. We cover towns and villages across Greater London. London is in our area too.
All of DA16, DA15 and DA6 is covered for thermal roof surveys. We cover properties on Days Lane, Hook Lane and Lyme Road and the roads around them. With the A207 close by, Welling is easy for us to reach for thermal roof surveys. If you are just outside Welling, we cover Crook Log (1 mile east), Blendon (1 mile south-east), Upton (1 mile east), Bexleyheath (1 mile east) and West Heath (1 mile north-east). Within a short drive, we also cover London (9 miles west), City of Westminster (12 miles west), Marylebone (12 miles west), Kensington (14 miles west), St Pancras (11 miles north-west) and Shoreditch (9 miles north-west).

What else we do in Welling
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Welling questions
Does a conservation area affect roof work in Welling?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is drone flying allowed in Welling?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around London City Airport comes within about 2 miles of Welling. 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. Strong wind or heavy rain also stops a small drone flying, and the rest of the survey doesn’t depend on the drone.
Can a thermal camera see water?
Not directly. It shows temperature, and wet materials frequently behave differently from dry ones. That’s why we check any patterns with moisture readings.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.
Does the weather affect a thermal survey?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Do I have to be there for the survey?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
Why act early in Welling
For buyers, a thermal survey adds detail that a visual inspection cannot give. Finding hidden moisture before exchange gives you facts to raise with the seller. Any roof job in Welling 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.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 with VAT included. We will tell you which package suits the questions you have.
What you get with us
- Package prices that include VAT
- Thermal imaging and drone inspection where they help
- An independent view of the roof
- Two decades and more of roof surveys
What we do, step by step
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. Most visits take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. For a visit in Welling, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- Tell us where we can park nearby
- Clear the way to the loft hatch
- For flats, check roof access has been agreed

What affects the price in Welling
When we price a survey, we consider:
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
- Building height and the viewpoints available
Prices quoted always include VAT, and the written report is part of the package. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.
Helping us price your survey
When you call or email, these details help:
- Your timetable, like an exchange date
- What kind of property and roof it is
- Where water is showing inside, if it is
- The property’s address and postcode
For a price for thermal roof surveys in Welling, phone 07833 053749 or email us. Some details about the property and the roof help us give you an accurate price.
Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Remember the conditions on the day affect the results
- Keep outlets and gutters clear to stop water sitting
- Make sure the loft can be reached safely
- File the images with your roof records
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. Once water gets under a membrane, it can travel far before it appears inside.
Signs you need a thermal roof survey in Welling
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there is a clear difference between inside and outside.
Things that frequently lead to a survey include:
- Stains that keep coming back
- Areas of a flat roof that may hold water
- Patches of heat loss across the roof
- Wet areas near outlets and upstands
Anyone responsible for a site like Danson Primary School will know that a view from above covers a wide roof far faster than walking it.
