How a thermal roof survey works in Thornton Heath
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. The report shows the images and explains what they may mean. We don’t give energy ratings or heat loss calculations. We’re frequently asked to look into areas losing heat at the eaves and junctions and areas of a flat roof that may hold water, across insulated roof spaces, loft conversions and flat roofs.
London’s roofs are often hard to see from the street: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. The weather decides the day: both drones and thermal cameras need the right conditions. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Checking the roof from ground level
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
What happens if roof problems are left?
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding the wet areas sooner keeps the work smaller. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.

Thornton Heath questions
Are there drone restrictions around Thornton Heath?
The answer turns on the exact location and the conditions on the day. 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. Each address is checked against all of them before the drone goes up. Every flight is checked against the Drone Safety Map first. A small drone cannot fly safely in strong wind or a downpour.
Is my home in Thornton Heath listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
What’s the best way to book?
To arrange a survey, call 07833 053749 or email us and tell us the address and what you’d like to know. We will confirm the price and find a day that suits.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Do you cover Thornton Heath for thermal roof surveys?
Yes. We survey roofs across London and South East England, Thornton Heath included.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Mention it when you get in touch and we will plan the survey around it.
Does the report include photographs?
Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.
Useful tips for Thornton Heath property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- File the images with your roof records
- Check the loft can be reached safely
- Check outlets after heavy rain
- Remember the conditions on the day affect the results
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. There is a 12-month follow-up too.
After repairs or a new covering, a later survey can confirm things are dry in suitable weather.
Roof by roof
Pitched slate and tile roofs
Slate and tile roofs are frequently harder to read with a thermal camera, because of the air space beneath. We back up what the camera shows with a look in the loft where we can.
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. It focuses the survey on the areas that matter.
Thermal roof surveys in Thornton Heath: local notes
About 2.4 miles north-east lies Kingswood House, a reminder of how long the area around Thornton Heath has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
If you look after a building like Winterbourne Junior Girls' School, a view from above covers a wide roof far faster than walking it. Parking in Thornton Heath, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier. If your home is one of the older ones in the streets near Church of St Stephen, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

How the survey works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take an hour or two for most homes, plus time to check any thermal findings with moisture readings. Surveys in Thornton Heath can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
