How a thermal roof survey works in Headstone
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It is important to know that the camera shows temperature, not water, 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. We survey loft conversions, commercial roofs and insulated roof spaces, and common reasons people get in touch are leaks far from where the stain appears and damp around roof outlets and upstands.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. We take care to focus on the roof we have been asked to look at, in Headstone as anywhere. Let us know about the building and access when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Leave it or get it looked at?
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.

Headstone questions
Are there drone restrictions around Headstone?
That depends on where the roof is and on the weather. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. The flight also waits for calm, dry weather.
Is my home in Headstone listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where applicable, structural analysis and a report on the same day.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
What happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can a thermal survey trace a roof leak?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings, as the camera alone can’t prove a leak.
Thermal roof surveys around Headstone
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. If your home in Headstone is one of them, bay roofs, hips and later dormers each have their own details. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
For site and facilities teams at buildings like Pinner Park Primary School, a drone or thermal camera can show a large roof in a single visit. If you run a business near St. George's Shopping Centre, large commercial roofs are often easiest to see from above or with a thermal imager.

Useful tips for Headstone property owners
Over many surveys, some simple habits stand out as worth the effort:
- Remember the conditions on the day affect the results
- Check outlets after heavy rain
- Heat the home normally on the days before
- Move stored items away from the loft hatch
Once we’ve been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, with our recommendations. With a Premium Survey, you get the report the same day.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
How it works
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit normally takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- 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 is safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Before we arrive
- Show us where any leaks or stains appear
- Make sure we can get to the back of the property

After a repair, some owners want to know whether the roof has dried out. Thermal images and moisture readings can suggest whether moisture is still trapped when the conditions on the day are suitable.

- Damp around roof outlets and upstands
- Areas of a flat roof that may hold water
- Thin or uneven insulation in the roof
- Damp around chimneys and parapets
