Thermal imaging roof survey in Leigh, Kent
Thermal imaging to find moisture and heat loss patterns in a roof around Leigh, with a written report you can act on. Weekday and weekend visits available.
- Damp patches with no obvious cause
- Wet areas near outlets and upstands
- Heat escaping through the roof
What we’re asked to look at in Leigh
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
Problems we come across frequently include:
- Leaks that are hard to trace
- Damp that repairs haven’t cured
- Water getting in at parapets and stacks
- Ceilings that feel colder in places
If yours is one of the older homes in the streets near St Mary's Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Questions to ask before booking
- Whether the inside of the roof is included
- Are they insured for the work?
- What experience they bring
- Whether you can ask questions once you have the report
About our thermal roof survey in Leigh
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. We survey loft conversions, ceilings below the roof and flat roofs, and common reasons people get in touch are moisture around outlets and upstands and wet insulation beneath the membrane.
In a small place like Leigh, open ground can mean strong wind. A small drone cannot fly safely in strong wind or a downpour, 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.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Rented homes, blocks and businesses
Businesses and commercial landlords can book us too. Larger roofs take longer.
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which helps when tenants work during the week.
What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect about one to two hours for most houses, and longer for a large or complex roof. Older roofs in small places like Leigh can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- The roof is inspected visually from safe viewpoints.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Getting ready for the survey
- Clear the way to the loft hatch
- Have any paperwork from past roof work to hand
- Mention any parking restrictions on your street
Getting a price
Getting a price is simple: just ring 07833 053749 or drop us an email and give us a few details about the property and we will explain which survey suits. We confirm the price before anything is booked.

Your questions about thermal roof surveys in Leigh
Do you cover Leigh?
We do. The survey and report are the same in Leigh as anywhere else.
Does a conservation area affect roof work in Leigh?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you go up on the roof?
Only if it is safe. We check everything that can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
How long will you be at the property?
Time on site depends on the roof, but most surveys take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The written report follows by email.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
Is thermal imaging included in your surveys?
Thermal imaging is included in our Premium Survey, from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Why get it checked now?
Before replacing a large flat roof, it helps to know how much of it is actually wet. Images backed by moisture readings show where problems seem to be before you spend. Older cottages and farmhouses around Leigh can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
Thermal roof survey starts from £400, including VAT. The final price depends on how big and how high the roof is, how it can be seen safely and the package you choose.
Why choose Independent Roof Survey in Leigh
- CAA-registered drone operator (Flyer ID and Operator ID)

Thermal roof surveys around Leigh
With Penshurst Place about 2 miles south-west, Leigh sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help.
Take a building like Leigh Primary School: big roofs are where aerial photos and thermal images show the most at once.

Different roofs, different checks
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. Thermal imaging can help show damp patterns around them.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We inspect the loft where it can be reached safely.
What we can’t see
To be straight with you, there are limits to any roof survey:
- Clear results when the conditions on the day are poor
- Whether the deck or roof structure is strong enough
- The condition of timbers we can’t see
