Thermal imaging roof survey in Ash, Kent
Thermal imaging to find moisture and heat loss patterns in a roof for Ash and the rest of Kent. We survey on any day of the week.
- Heat escaping through the roof
- Cold spots on ceilings under the roof
- Thin or uneven insulation in the roof
How a thermal roof survey works in Ash
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera does not see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’ve noticed cold spots on ceilings under the roof and damp patches with no obvious cause, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Ash may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
You receive the findings 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
Our packages start from £150, with VAT included. What you pay for your roof depends on:
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
- The package you choose: Basic, Standard or Premium
- Building height and the viewpoints available
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
Getting in touch
When you call or email, these details help:
- Anything about access we should know
- The property’s address and postcode
- Any stains, drips or damp patches you’ve seen indoors
- Dates you’re working to, such as exchange
If you have photos of the roof, send them over. Take them safely from the ground or a window. To send them or to book, call 07833 053749 or send us an email.
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Do not switch the heating off ahead of the visit
- Keep the report to compare against after any repair
- Photograph damp patches with the date
- Check from ground level or a window, never by climbing
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There is a 12-month follow-up too.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
Why it’s worth a survey now in Ash
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. Where a roof is exposed, as many are in small places like Ash, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for the job before booking.

Common questions in Ash
Will you come out to Ash?
Yes, Ash is covered. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Is my home in Ash listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it is warm inside and cold outside. Where we can reach the loft safely, we check there too.
Will you walk on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How many surveys have you done?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.

What you can safely check yourself
A DIY look is useful, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
How the survey works
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can be seen safely, from the ground, from windows, in the loft space and by drone where applicable. The survey usually takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Older rural homes like those around Ash can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Keep pets inside or away from the areas we are looking at
- If it isn’t your property yet, arrange access through the agent
Getting a price
Getting a price is simple: just call 07833 053749 or drop us an email, let us know about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
Advice
Common roof problems in Ash
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so we know where to take moisture readings.
Signs worth acting on include:
- Ceilings that feel colder in places
- Possible trapped moisture under a flat roof covering
- Damp around chimneys and parapets
- Water that travels before it shows
For an older house near a landmark such as Parish Church of Saint Peter and Saint Paul, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view by drone or thermal camera helps.
What to check before booking
- Which viewpoints they use to see the roof
- Their drone registration, if they fly one
- How long the report takes to arrive
- Whether the inside of the roof is included
Airspace, weather and Ash roofs
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. You will also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Lullingstone Castle, about 4.2 miles west, is one of the historic houses in the wider area around Ash. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
For site and facilities teams at buildings such as New Ash Green Primary School, thermal images can show where wet insulation sits under a big flat roof.
