Do you need a thermal roof survey in Sanderstead?
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. It can suggest which areas may be wet and which seem dry, so moisture readings can be targeted.
People usually book a survey when they’ve noticed something like this:
- Cold areas below the roof
- Thin or uneven insulation in the roof
- Water that travels before it shows
- Stains that keep coming back
Sanderstead is in London, so parking needs planning: let us know about permits, visitor bays or off-street space as you book.
Questions to ask before you book
- Which limits apply to the survey
- What exactly goes into their report
- When you will get the report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
About our thermal roof survey in Sanderstead
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. We survey pitched roof slopes, loft conversions and ceilings below the roof, and common reasons people get in touch are damp where roofs meet walls and chimneys and ceilings that feel colder in places.
London airspace is busy and tightly controlled: 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. Before a drone goes up in Sanderstead, the address is checked against all of them, and where permission is needed, the flight waits for it.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Sanderstead questions
Is parking a problem for a survey in Sanderstead?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is drone flying allowed in Sanderstead?
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 thermal imaging good for finding leaks?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It’s used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
What happens after the survey?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Does thermal imaging work on slate and tile roofs?
It can help, but the results are often less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we combine it with an inspection from the loft where there is safe access.
What we do, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. A typical visit takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. London terraces rarely offer a view of the whole roof from one spot, so in Sanderstead 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, let us know who can let us into the shared parts.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- Agree roof access with the managing agent if it’s shared
- If it isn’t your property yet, arrange access through the agent
- Gather any invoices or paperwork from past roof work

Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- Don’t switch the heating off before the visit
- Keep a record of when stains appear
- Keep the report to compare against after any repair
- Photograph damp patches with the date
If you’re buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether that’s asking for work or discussing the price.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps frequently appear after work in the loft.
Can I check my roof myself?
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Thermal roof surveys in Sanderstead: local notes
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Historic houses such as Addington Palace, about 2.3 miles north-east, show how far back building in the area around Sanderstead goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you own one of the older houses in the streets near Church of All Saints, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help. For site and facilities teams at buildings such as Gresham Primary School, a drone or thermal camera can show a large roof in a single visit.
