Thermal imaging roof survey in Barham, Kent
Thermal imaging to find moisture and heat loss patterns in a roof in Barham. More than 5,000 surveys completed across London and South East England.
- Areas of a flat roof that may hold water
- Missing or slipped insulation
- Damp where roofs meet walls and chimneys
About our thermal roof survey in Barham
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It isn’t an energy rating or a heat loss calculation. If you’re worried about wet areas near outlets and upstands and wet insulation beneath the membrane, we can find out what’s behind it, on pitched roof slopes, ceilings below the roof and flat roofs alike.
In a small place like Barham, open ground can mean strong wind. A small drone can’t fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Questions from Barham
Is my home in Barham listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Will you come out to Barham?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
How much does a thermal roof survey cost?
It comes with our Premium Survey, which starts from £400. That also includes a full inspection, a drone inspection where it applies, structural analysis and a same-day report.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
How long does the survey take?
It usually takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. The written report follows by email.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Does thermal imaging work on slate and tile roofs?
It can help, but the results are often less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we also look from the loft where it’s safe.

What we do, step by step
Once we’ve finished looking, we write up our findings in a report with photos, emailed to you. On timing, it usually takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Around Barham, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- Let us know about parking before the day
- Unlock side gates and any roof access doors
- Show us where any leaks or stains appear

Related advice
Checking the roof from ground level
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Airspace, weather and Barham roofs
With Goodnestone Park about 3.9 miles north-east, Barham sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. 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. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help.
For site and facilities teams at buildings like Barham Church of England Primary School, a drone or thermal camera can show a large roof in a single visit.
Barham is about 6 miles south-east of Canterbury, in Kent. In Barham, as across Kent, every roof gets the same careful survey. Our Kent coverage includes Barham. You can also see our page for Canterbury.

Landlords, agents and block managers in Barham
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or use the contact form with the addresses.
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
What we look for on each type of 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.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. We check any patterns with moisture readings.
What we can’t see
It is useful to know what a survey will not do before booking:
- Proving moisture from the images alone
- Readings unaffected by sun, shade or reflections
- Hidden layers that need to be opened up to check
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before you book. What a survey covers and does not.
What this survey covers
- Ceilings below the roof
- Commercial roofs
- Flat roofs
- Loft conversions
- Pitched roof slopes
- Insulated roof spaces
When to book a survey in Barham
On big commercial and residential flat roofs, thermal imaging helps owners plan. Patterns can point to wet areas and show which parts look sound, so moisture readings can be targeted.
Problems we come across frequently include:
- Leaks that are hard to trace
- Stains that keep coming back
- Damp where roofs meet walls and chimneys
- Moisture around outlets and upstands
For an older house near a landmark such as Church of St John the Baptist, 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.
Questions to ask before you book
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- How long the report takes to arrive
- Whether you can ask questions once you have the report
- What they won’t be able to tell you
