Thermal imaging roof survey in Oakleigh Park, Greater London
Thermal roof surveys in Oakleigh Park from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us.
- Moisture around outlets and upstands
- Thin or uneven insulation in the roof
- Areas losing heat at the eaves and junctions
What a survey costs
When we price a survey, we consider:
- The package you choose: Basic, Standard or Premium
- Commercial roofs and larger buildings
- The shape of the roof and its details
- How tall the building is and how easy the roof is to see
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
What we need to know
You do not need to know any roofing terms. Just let us know:
- Pictures from the garden or a window, if you have them
- The kind of building and roof involved
- Where any leaks, stains or damp patches show inside
- Anything about access we should know
Thermal roof survey starts from £400, including VAT. The exact figure depends on the roof and the package, and you can ring 07833 053749 or email us to find out.
How a thermal roof survey works in Oakleigh Park
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It is 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. Typical surveys look at damp around roof outlets and upstands and damp patches with no obvious cause, across commercial roofs, loft conversions and pitched roof slopes.
Flying in London takes more checking than most places: 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 Oakleigh Park is checked before any drone flight, and permission is never taken for granted.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What we are asked to look at in Oakleigh Park
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
A survey makes sense if you’ve noticed:
- Moisture around outlets and upstands
- Missing or slipped insulation
- Damp around chimneys and parapets
- Water that travels before it shows
For businesses in and around places such as Grand Arcade, thermal images can show trapped moisture across a wide commercial roof.
What to check before booking
- Whether the inside of the roof is included
- Whether they hold professional indemnity and public liability insurance
- How long the report takes to arrive
- Whether any drone flown is registered with the CAA
The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a London area like Oakleigh Park, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can be seen safely from the ground, windows, the loft and, where it is safe, the roof itself.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Check we can get to the back of the property
- Let us know about parking near the property
- Buyers: confirm access with the estate agent or seller

Related advice
For landlords and managing agents
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we’ll plan the visit with that in mind.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Flying and imaging in Oakleigh Park
Historic houses such as Heath Hall, about 3.5 miles south, show how far back building in the area around Oakleigh Park goes. 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. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Oakleigh Park is one of them, bay roofs, hips and later dormers each have their own details. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
As a London address, Oakleigh Park can be tricky for parking: let us know about permits, visitor bays or off-street space when booking, as a space near the door can’t be promised. Take an older house close to Church of St John: steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view by drone or thermal camera helps.

FAQs for Oakleigh Park
Is my home in Oakleigh Park listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Can parking be tricky for a visit in Oakleigh Park?
Parking in Oakleigh Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
What’s in the report?
It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Does the report include photographs?
Yes. Photographs are part of every report.
Do you test for asbestos?
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.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
What we look for on each type of roof
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We combine a visual check of cracks with the thermal images around them.
Loft insulation
Insulation frequently gets moved during work in the loft. Thermal images can show where it has been pushed aside.

When you need someone else
It is a careful look at the roof, not the whole story. The main limits are:
- Proving moisture from the images alone
- Reliable images in rain, strong wind or on a wet roof surface
- Insulation values or heat loss calculations
