How a thermal roof survey works in Charlton
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. We explain what each pattern may mean, what the moisture readings found and what we recommend. With a Premium Survey, the report reaches you the same day. If you have questions, the in-person consultation gives you time to go through them. There is a 12-month follow-up as well. Common reasons to book are damp where roofs meet walls and chimneys and damp around roof outlets and upstands, across commercial roofs, flat roofs and pitched roof slopes.
Some older homes in villages like Charlton are listed or in a conservation area. A look from above or with a thermal imager doesn’t touch the roof, so it is a gentle way to see the condition of an old roof, before anyone decides what work it needs. Check with the council before planning any work on a listed building or one in a conservation area.
The written findings come 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.

Common questions in Charlton
Does a conservation area affect roof work in Charlton?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Charlton?
Yes, Charlton is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Will the camera show exactly where the water is?
Not directly. It shows temperature, and wet materials often behave differently from dry ones. That’s why we check any patterns with moisture readings.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
Does the weather affect a thermal survey?
The weather makes a real difference. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we talk through the forecast when you book.
What happens after the survey?
The report arrives by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
How the survey works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes about one to two hours at a typical home, though large, tall or awkward roofs take more time. Rural addresses near Charlton can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photographs and our recommendations.
How to prepare
- Check the loft hatch can be reached
- Tell us where we can park nearby
- Leave side gates unlocked

Different roofs, different checks
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Reflections from shiny surfaces can affect readings, which we allow for.
Landlords, agents and block managers in Charlton
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or use the contact form with the addresses.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
When to book a survey in Charlton
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.
Look out for signs like these:
- Damp around roof outlets and upstands
- Leaks that are hard to trace
- Missing or slipped insulation
- Areas losing heat at the eaves and junctions
Historic houses like Hampton Court Palace, about 4.6 miles east, show how far back building around Charlton goes. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings.
Before booking any roof surveyor
- What happens after the report arrives
- What insurance they carry
- How long the report takes to arrive
- Their drone registration, if they fly one
Flying and imaging in Charlton
Charlton is about 2 miles from the edge of the flight restriction zone around Heathrow Airport. If your survey includes the drone, we check the exact boundary for the address before flying. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
If you look after a building like Littleton CofE Infant School, a drone or thermal camera can show a large roof in a single visit. For an older house near a landmark such as Church of St Mary Magdalene, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

Tips from our surveys
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Note where damp appears and after what weather
- Clear a path to the loft hatch before we arrive
- Keep dated photos of any marks on ceilings
- Heat the home normally on the days before
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it’s easy to find each area on the roof.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
