Thermal imaging roof survey in Penshurst, Kent
Not sure what state the roof is in? We carry out thermal roof surveys in Penshurst and across Kent, with plain-English findings.
- Wet insulation beneath the membrane
- Ceilings that feel colder in places
- Wet areas near outlets and upstands
About our thermal roof survey in Penshurst
Thermal imaging works best in the right conditions. A sunny day before the survey, a dry roof surface and little wind all help. Rain, a strong wind or heavy cloud can make the images less clear. We talk through the forecast when booking, and our report notes the conditions and how they affected what we saw. If you are worried about leaks that are hard to trace and heat escaping through the roof, we can find out what’s behind it, whatever the roof.
In a small place like Penshurst, open ground can mean strong wind. A small drone can’t fly safely in high wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

How we price thermal roof surveys
A few things affect what a survey costs:
- How tall the building is and how easy the roof is to see
- House, block, shop or office
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
Our price is from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.
What to let us know when you contact us
Getting the details right at the start saves time. It helps to include:
- What kind of property and roof it is
- Whether there’s a loft hatch, a shared roof or tricky access
- What’s prompted the survey
- Any stains, drips or damp patches you’ve seen indoors
You can call us seven days a week. For a price or to book, ring 07833 053749 or use the contact form.
Common roof problems in Penshurst
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there’s a clear difference between inside and outside.
Look out for signs like these:
- Patches of heat loss across the roof
- Water that travels before it shows
- Damp around roof outlets and upstands
- Cold spots on ceilings under the roof
Take a building like Penshurst Church of England Voluntary Aided Primary School: thermal images can show where wet insulation sits under a big flat roof.

Honest limits
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- A formal energy assessment
- Reliable images in rain, strong wind or on a wet roof surface
- A structural engineer’s assessment
If in doubt, phone 07833 053749 or drop us an email and we’ll point you to the right survey. What a survey covers and doesn’t.
What we look at
- Ceilings below the roof
- Loft conversions
- Pitched roof slopes
- Insulated roof spaces
- Flat roofs
- Commercial roofs
Different roofs, different checks
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. We use the camera and moisture readings to help follow it.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and can’t be read from them.
Why it is worth a survey now in Penshurst
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. That helps you and your roofer decide what really needs replacing. Older cottages and farmhouses around Penshurst can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400, both with VAT included. You will know the price for your survey before booking.

Penshurst questions
How do I find out if my home in Penshurst is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Penshurst within the area you cover?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
How does a thermal imaging roof survey work?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
Does someone need to be in?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
Airspace, weather and Penshurst roofs
Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Steep or complicated roofs are often hard to see from ground level, which is where close-up aerial shots and thermal images help. About 0.4 miles north-east lies Penshurst Place, a reminder of how long the area around Penshurst has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof.
The streets around a church such as Church of St John the Baptist are frequently among the oldest in a place, and if your house is among the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image.

How it works
We do not take risks to get a closer look. Everything that can safely be seen is inspected, and if part of the roof can’t be seen, the report says so. Most visits take roughly 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. In a hamlet or village like Penshurst, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it is safe.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- If it is not your property yet, arrange access through the agent
- Tell us about any leaks, stains or damp patches you know of
