Thermal imaging roof survey in Hartley, Kent
Thermal roof surveys in Hartley and the rest of Kent. We survey on any day of the week.
- Possible trapped moisture under a flat roof covering
- Patches of heat loss across the roof
- Thin or uneven insulation in the roof
Leave it or get it looked at?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Arranging work in a smaller place like Hartley is easier with notice than in an emergency. A survey gives you that notice.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Why book us in Hartley
- Prices that include VAT
- Surveys on weekdays, Saturdays and Sundays

Thermal roof survey in Hartley: what you get
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it’s colder outside. The report shows the images and explains what they may mean. It isn’t an energy rating or a heat loss calculation. We survey pitched roof slopes, loft conversions and commercial roofs, and people most frequently book us about leaks far from where the stain appears and stains that keep coming back.
In smaller places like Hartley, many homes are bungalows and houses with roofs you can partly see from ground level. The parts you cannot see, like rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. The forecast decides the day, as calm, dry conditions suit both. Close-up images often show wear on ridges, verges and flashings that can’t be judged properly from ground level.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

What we do, step by step
The aim of the visit is simple: to see as much of the roof as can safely be seen and record it clearly. Notes and photos go into the written report. It usually takes between one and two hours for a house, with bigger or more complicated roofs taking longer. Some parts of a survey depend on the weather, so a visit to Hartley is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent
- Move anything stored under the loft hatch
- Jot down any questions you want answered

Roof by roof
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
Checking the roof from the ground
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.

Signs you need a thermal roof survey in Hartley
Flat roofs that have leaked for a while can have wet insulation under the covering. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
People typically book a survey after spotting something like this:
- Ceilings that feel colder in places
- Missing or slipped insulation
- Wet areas near outlets and upstands
- Leaks far from where the stain appears
Historic houses such as Cobham College, about 3.9 miles east, show how far back building around Hartley goes. Older roofs nearby can be steep and hard to see from the ground, and a survey from the air or with a thermal camera does not touch the roof itself.
Before booking anyone
- Whether the roof space is looked at, where there is one
- Is there a chance to talk the report through?
- Whether any drone flown is registered with the CAA
- Their track record with similar roofs
Hartley questions
Is Hartley in the area you cover?
We do. The survey and report are the same in Hartley as anywhere else.
Will you come out to Hartley?
Yes, we do. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Tell us about it when booking and we will explain what’s needed.
How do I arrange a thermal roof survey in Hartley?
To book, phone 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How long does the survey take?
Most surveys take an hour or two at most homes, while a commercial roof takes nearer three to four hours. The report follows by email.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
What a thermal roof survey does not cover
We only report whatever is safely visible on the day, so there are some things a survey can’t cover:
- Seeing water directly, as the camera shows temperature, not moisture
- Hidden layers that need to be opened up to check
- Clear results when the conditions on the day are poor
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. The full list of what we check.
What this survey covers

Thermal roof surveys in Hartley: local notes
Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If you look after a building like Hartley Primary Academy, a view from above covers a wide roof far faster than walking it. Take an older house close to Church of Saint Mary: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps.
