Thermal roof survey in Bishopsgate: what you get
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’s important to know that the camera shows temperature, not water, so we check what it shows 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. If you’re worried about water getting in at parapets and stacks and moisture around outlets and upstands, a survey will tell you what’s going on.
Flying in London takes more checking than most places: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Every address in Bishopsgate is checked before any drone flight, and where permission is needed, the flight waits for it.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

FAQs for Bishopsgate
Is my home in Bishopsgate listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Will parking be an issue for a roof survey in Bishopsgate?
It can be, so it helps to tell us about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
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 you book.
Is Bishopsgate in your area?
Yes. We survey roofs in Bishopsgate and the rest of Greater London. To book, call 07833 053749 or drop us an email.
How experienced are you?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.
How long is the visit?
Most surveys take about 1–2 hours at most homes, or half a day or so for a commercial building. The report follows by email.
Is this an asbestos survey?
No. Asbestos surveys and testing aren’t part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.

Roof by roof
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.
Felt and asphalt flat roofs
Felt and asphalt sit tight to the layers below, which frequently helps the camera pick up differences. Any patterns are checked with moisture readings.
What we do, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes roughly 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. If you have questions on the day, just ask. London terraces rarely offer a view of the whole roof from one spot, so in Bishopsgate we work round the house, using the street, the windows, the loft and any safe vantage point behind it. 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.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Move anything stored under the loft hatch
- Have any questions written down, so nothing gets missed
- Unlock side gates and any roof access doors
Arrange a survey
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or drop us an email.
