How a thermal roof survey works in Rosehill
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. It also includes a drone inspection where it applies, a structural analysis and a same-day report. There’s an in-person consultation as well, plus a follow-up 12 months later. You can call 07833 053749 or send us an email with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. Typical surveys look at cold spots on ceilings under the roof and damp patches with no obvious cause, on loft conversions, ceilings below the roof and pitched roof slopes.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every address in Rosehill is checked before any drone flight, and where permission is needed, the flight waits for it.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What a thermal roof survey looks like in Rosehill
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. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help. The wider area around Rosehill has a long history of building, with Nonsuch Mansion about 2.6 miles south-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings like Tweeddale Primary School, a drone or thermal camera can show a large roof in a single visit. For an older house near a landmark like St Peter's Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Rosehill is about 3 miles south-east of Wimbledon, in Greater London. Rosehill is part of the area we cover across London and South East England. Across Greater London, we cover Rosehill and the places around it. You can also see our page for London.

When to book a survey in Rosehill
Some defects simply can’t be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
A survey can pick up problems such as:
- Damp around chimneys and parapets
- Heat escaping through the roof
- Damp patches with no obvious cause
- Missing or slipped insulation
Shop and office owners around Centrale Croydon may find that big, flat commercial roofs are where close-up aerial shots and thermal images help most.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Which viewpoints they use to see the roof
- What they will not be able to tell you
- Whether VAT is added on top
When you need someone else
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- An energy rating for the building
- Confirming water without moisture readings
- Readings unaffected by sun, shade or reflections
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we’ll give you a straight answer before booking. What our survey covers.
What this survey covers
- Ceilings below the roof
- Commercial roofs
- Loft conversions
- Insulated roof spaces
- Pitched roof slopes
- Flat roofs
What happens if roof problems are left?
A poorly insulated roof loses heat year after year. The camera can point to gaps and thin areas in the insulation, so you know where to put things right. 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.

Checking the roof from ground level
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
The survey, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take roughly 1–2 hours for a house, and longer for a large or complex roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in Rosehill 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 talk through the roof, any damp or leaks, and the weather expected on the day.
- We check the roof from the ground, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there is safe access.
- You get a report with thermal images, photographs and our recommendations.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches
- If it isn’t your property yet, arrange access through the agent
Arrange a survey
Booking is simple: just call 07833 053749 or drop us an email and give us some details about the property and we’ll suggest the right survey. The price is agreed up front.

Before and after the survey
These tips come from what we see on roofs every week:
- Keep outlets and gutters clear to stop water sitting
- Tell us where and when you’ve seen damp or stains
- Remember the conditions on the day affect the results
- Leave the roof to people with safe access
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
Rosehill questions
Can you fly a drone over a roof in Rosehill?
It depends on the exact address and the weather 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. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather.
How do I find out if my home in Rosehill is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Can you survey at the weekend?
We carry out surveys on weekdays, Saturdays and Sundays. To arrange a date, phone 07833 053749 or use the contact form.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How do I book a survey in Rosehill?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
What happens after the survey?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
