Thermal roof survey in Coulsdon
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, 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. If you’ve noticed cold spots on ceilings under the roof and thin or uneven insulation in the roof, we can find out what’s behind it, whatever the roof.
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. Every address in Coulsdon is checked before any drone flight, and permission is never taken for granted.
After the visit, you get a report with photographs, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Why it’s worth a survey now in Coulsdon
Wet insulation under a flat roof does not dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Prices quoted always include VAT, and the written report is part of the package. Prices start from £400, including VAT. Size, height and access decide where your roof falls.

Do you need a thermal roof survey in Coulsdon?
Some buyers want extra detail before they commit to a purchase. The Premium Survey brings thermal imaging and a drone inspection where applicable, with a report the same day, which helps when timescales are tight.

- Areas losing heat at the eaves and junctions
- Missing or slipped insulation
- Damp where roofs meet walls and chimneys
- Cold areas below the roof
Coulsdon is in London, so parking needs planning: let us know about permits, visitor bays or off-street space as you book, as a space near the door cannot be promised.
Questions to ask before you book
- Will the report include photos?
- What’s outside the scope of the survey
- Whether the loft is part of the inspection
- What insurance they carry
The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes about 1–2 hours for a house, with bigger or more complicated roofs taking longer. You’re welcome to ask questions while we are there. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- If you’re buying, let the agent know when we are coming
- Find any records of previous roof work
- Make sure the loft hatch can be reached

Thermal roof surveys around Coulsdon
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as 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 Coulsdon has a long history of building, with Nonsuch Mansion about 4.9 miles north-west. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Anyone responsible for a site like Smitham Primary School will know that big roofs are where aerial photos and thermal images show the most at once. Take an older house close to St Andrew's Church: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.
How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
FAQs for Coulsdon
Will parking be an issue for a roof survey in Coulsdon?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Does a conservation area affect roof work in Coulsdon?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. We don’t give energy ratings or heat loss calculations, but the report shows where to look more closely.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance.
Is this an asbestos survey?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, like 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.
Is thermal imaging good for finding leaks?
It’s a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source cannot be confirmed, we’ll say what could help next, such as electronic leak detection.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
