Thermal roof surveys for homes and businesses in North Cray
Thermal imaging is part of our Premium Survey, which starts from £400. It also includes a drone inspection where it applies, a structural analysis and a same-day report. There is an in-person consultation as well, plus a follow-up 12 months later. To book, just phone 07833 053749 or send us an email with the address and what you’ve noticed. Larger commercial roofs are quoted for their size. If you’re worried about patches of heat loss across the roof and damp that repairs haven’t cured, we can find out what’s behind it, whatever the roof.
London roofs sit shoulder to shoulder in terraces and blocks, so privacy and neighbours matter as much as the view. We take care to focus on the roof we have been asked to look at. Mention access, height and anything unusual about the building when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What you can safely check yourself
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
How the survey changes by roof type
Parapets, valleys and junctions
Problems where roof slopes and walls meet are frequently hidden. We combine a close visual check with the thermal images.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
North Cray: your questions answered
Is drone flying allowed in North Cray?
The answer turns on the exact location and the conditions on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus 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. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. A small drone can’t fly safely in high wind or heavy rain, and the rest of the survey does not depend on the drone.
How do I find out if my home in North Cray is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is thermal imaging useful on pitched roofs?
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.
Can you check my loft insulation with a thermal camera?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. Findings are checked with moisture readings.
What will the report tell me?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put with the most urgent first where relevant.
What’s the best way to book?
Simply ring 07833 053749 or drop us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.
Drones, thermal imaging and North Cray roofs
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. The wider area around North Cray has a long history of building, with Hall Place and Gardens about 1.4 miles north-east. 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.
Take a building like Royal Park Primary Academy: thermal images can show where wet insulation sits under a big flat roof. Controlled parking zones are common in London, so mention any permit rules for North Cray.
North Cray is about 2 miles east of Sidcup, in Greater London. From houses to flats and shops in North Cray, we can survey the roof on a weekday or at the weekend. Our Greater London coverage includes North Cray and the places around it. Our London page covers surveys nearby.

What we do, step by step
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. London terraces rarely offer a view of the whole roof from one spot, so a visit in North Cray moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Make a note of anything you’d like us to look at

Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Heat the home normally on the days before
- Leave the roof to people with safe access
- Keep outlets and gutters clear to stop water sitting
- Keep the report to compare against after any repair
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
When to book a survey in North Cray
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when it is warm inside and cold outside.
Things that frequently lead to a survey include:
- Cold spots on ceilings under the roof
- Water that travels before it shows
- Water getting in at parapets and stacks
- Moisture around outlets and upstands
For businesses in and around places such as Broadway Shopping Centre, big, flat commercial roofs are where photos from the air and thermal images help most.
