How a thermal roof survey works in Swanley
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That’s why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. If a finding can’t be confirmed, the report suggests a next step. We’re often asked to look into water getting in at parapets and stacks and leaks far from where the stain appears, across insulated roof spaces, loft conversions and commercial roofs.
Places like Swanley can be near small airfields or other airspace restrictions, so every drone flight starts with a check of the Drone Safety Map. Exposed sites can be windy, and a small drone can’t fly safely in strong wind, while thermal imaging also works best with little wind. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photo. You will see the good as well as the bad.

How it works
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a smaller place like Swanley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- Check pets are kept safely away
- Make sure the loft hatch can be reached
- Check we can get to the back of the property

Advice
Do you need a thermal roof survey in Swanley?
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. Temperature patterns can help narrow down where to look.
A survey can pick up problems like:
- Missing or slipped insulation
- Stains that keep coming back
- Wet insulation beneath the membrane
- Leaks far from where the stain appears
If you own one of the older houses in the streets near St Mary the Virgin, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from above or with a thermal imager helps.
What to check before booking
- Whether the loft is part of the inspection
- Which limits apply to the survey
- How much experience they have with roofs like yours
- Whether VAT is in the quoted price
Why get it checked now?
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. It helps when deciding whether to patch an area or replace the roof. With lower homes, common in places like Swanley, there is little between a roof defect and the ceiling, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
Prices quoted always include VAT, and the written report is part of the package. Prices start from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Swanley: your questions answered
Do you carry out roof surveys in Swanley?
Yes, Swanley is within the area we cover. We survey roofs across London and South East England. You can phone 07833 053749 or send us an email with the address and some details.
Do you cover smaller places like Swanley?
Yes, Swanley is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Tell us about it when you book and we will explain what’s needed.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
Will you go up on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and the report notes anything we couldn’t see.
Is thermal imaging useful on pitched roofs?
It can be useful, though pitched roofs are normally harder to read. The air space under slates and tiles can hide patterns, so we also look from the loft where it’s safe.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Let us know your preferred days when you book.
Drones, thermal imaging and Swanley roofs
If your survey includes the drone, the flight is checked against the Drone Safety Map first. Lullingstone Castle, about 2.9 miles south, is one of the historic houses in the wider area around Swanley. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
If you look after a building such as St Bartholomew's Catholic Primary School, thermal images can show where wet insulation sits under a big flat roof.
Swanley is about 3 miles east of Orpington, in Kent. Swanley gets the same service as everywhere else we work: a careful inspection, photos and a written report. We cover towns and villages across Kent. London is in our area too.

Other services in Swanley
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
How the survey changes by roof type
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below frequently show. Shiny surfaces can reflect heat, so we take care reading the images.
Prices for thermal roof surveys in Swanley
What a survey costs depends on the time and equipment it needs. That comes down to:
