How a thermal roof survey works in Swanscombe
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where applicable, structural analysis and a report on the same day. An in-person consultation and a 12-month follow-up are included too. You can phone 07833 053749 or send us an email with the address and a note of what you’ve noticed. For big commercial roofs, we quote on size and access. We are often asked to look into damp patches with no obvious cause and gaps in loft insulation, on loft conversions, insulated roof spaces and ceilings below the roof.
Even in a smaller place like Swanscombe, there may be airfields or restrictions nearby, so every drone flight starts with a check of the Drone Safety Map. Open ground can mean stronger wind, which also affects whether a small drone can fly, while thermal imaging also works best with little wind. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

How we price thermal roof surveys
A few things affect what a survey costs:
- Features like valleys, chimneys, dormers and parapets
- Whether it is a home or a commercial building
- How tall the building is and how easy the roof is to see
- The roof’s overall size
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
What to tell us when you get in touch
When you call or email, these details help:
- What made you get in touch
- The type of building and roof, like pitched or flat
- Where any leaks, stains or damp patches show inside
- Your timetable, like an exchange date
We survey roofs on weekdays and at weekends. To find a date that works for you, ring 07833 053749 or drop us an email.

When to book a survey in Swanscombe
Some owners book because the rooms under the roof feel cold. Missing or slipped insulation can stand out as temperature differences, especially when it’s warm inside and cold outside.
Here are some of the things we see frequently:
- Possible trapped moisture under a flat roof covering
- Cold areas below the roof
- Water that travels before it shows
- Water getting in at parapets and stacks
The streets around a church such as Church of St Mary are often among the oldest in a place, and if your house is among the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps.
Questions to ask before you book
- What they will not be able to tell you
- Whether you can ask questions once you have the report
- What insurance they carry
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Why get it checked now?
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. Blocked gutters on homes around Swanscombe overflow and soak walls, particularly where trees overhang. It is easy to sort the cause early and slow to dry a damp wall.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £400, including VAT.

Questions from Swanscombe
Do you cover Swanscombe?
We do. Every survey there gets the same written report with photos.
Will you come out to Swanscombe?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Will you walk on the roof?
Only if it’s safe. We inspect what can be seen safely: 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 can’t see is noted in the report.
How soon will I get the report?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when you book.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Can a thermal survey trace a roof leak?
It often helps show where to look. Patterns can suggest where trapped water has spread. It is used alongside a close inspection and moisture readings because the camera cannot confirm water on its own.
Can you use a thermal camera on a sloping roof?
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 combine it with an inspection from the loft where there’s safe access.
What happens on the day
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes about 1–2 hours for a house; commercial roofs usually need 3–4 hours. A visit to a smaller place like Swanscombe is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- Let us know where we can park nearby
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work
How to book
Not sure which survey you need? It’s easiest to phone 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.

Thermal roof surveys in Swanscombe: local notes
The coast is about 4 miles or less from Swanscombe, and coastal wind can be strong. Calm, dry conditions after a sunny day suit thermal imaging best, so the visit is planned around the forecast. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Steep or complicated roofs are frequently hard to see from ground level, which is where close-up aerial shots and thermal images help.
Anyone responsible for a site like Knockhall Primary School will know that a view from above covers a wide roof far faster than walking it. For businesses in and around places like Bluewater, thermal images can show trapped moisture across a wide commercial roof.

Honest limits
Without opening up the roof, some things stay hidden, so a survey has limits:
- Reliable images in rain, strong wind or on a wet roof surface
- The condition of timbers we cannot see
- A formal energy assessment
If you are not sure which survey you need, call 07833 053749 or drop us an email and we will give you a straight answer. The full list of what we check.
What this survey covers
- Loft conversions
- Ceilings below the roof
- Flat roofs
- Pitched roof slopes
- Commercial roofs
- Insulated roof spaces
Tips from our surveys
These tips come from what we see on roofs every week:
- Move stored items away from the loft hatch
- Let us know where and when you’ve seen damp or stains
- Ask us about the forecast if rain is expected
- Use the report as a baseline for later checks
Buyers can use the findings when talking to the seller or agent. What you do with it is up to you, whether that’s asking for work or discussing the price.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
