Landlord and commercial surveys in Leaves Green
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 will plan the survey around it.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
Thermal roof surveys for homes and businesses in Leaves Green
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 is important to know that the camera shows temperature, not water, 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. We survey commercial roofs, ceilings below the roof and flat roofs, and people most often book us about cold areas below the roof and leaks far from where the stain appears.
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 Leaves Green, the address is checked against all of them, and where permission is needed, the flight waits for it.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

What a survey costs
Several things affect the price of a survey:
- Extensions, dormers and garages with roofs of their own
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
- How complicated the roof is, with its valleys, chimneys and parapets
Every price we give includes VAT. Our price is from £400, including VAT. We confirm the price for the job before booking.
What to tell us when you contact us
If you can, have these to hand when you contact us:

Why act early in Leaves Green
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. It helps when deciding whether to patch an area or replace the roof. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £400, including VAT.
Why book us in Leaves Green
- An independent look at the roof
- Drones and thermal imaging where applicable
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Plain-English reports with photos

Signs you need a thermal roof survey in Leaves Green
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. A thermal survey, checked with moisture readings, can give a much clearer picture.
Things that frequently lead to a survey include:
- Water getting in at parapets and stacks
- Cold areas below the roof
- Damp around roof outlets and upstands
- Areas of a flat roof that may hold water
If you look after a building such as Meridian High School, thermal images can show where wet insulation sits under a big flat roof.
Questions to ask before booking
- Which limits apply to the survey
- What follow-up you get after the report
- Their track record with similar roofs
- Do they have a CAA Flyer ID and Operator ID for drone work?
Leaves Green: your questions answered
Can you fly a drone over a roof in Leaves Green?
That depends on where the roof is and on the weather. Leaves Green is about 1 mile from Biggin Hill Airport, so the Drone Safety Map is checked for restrictions around it before we fly. 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. Each address is checked against all of them before the drone goes up. A small drone cannot fly safely in strong wind or heavy rain.
Is my home in Leaves Green listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is thermal imaging good for finding leaks?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source can’t be confirmed, we’ll say what could help next, such as electronic leak detection.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with the freeholder or managing agent. Tell us about it as you book and we will plan the survey around it.
Can a thermal camera see water?
Not directly. It shows temperature, and wet materials often behave differently from dry ones. That’s why we check any patterns with moisture readings.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
How many surveys have you done?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
When you need someone else
We only report everything that’s safely in view on the day, so some things are outside what a survey can do:
- Readings unaffected by sun, shade or reflections
- Seeing water directly, as the camera shows temperature, not moisture
- An energy rating for the building
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we’ll give you a straight answer. The full list of what we check.

Airspace, weather and Leaves Green roofs
Biggin Hill Airport is about 1 mile from Leaves Green. If your survey includes the drone, the Drone Safety Map is checked for restrictions first. About 1.1 miles east lies Down House, a reminder of how long the area around Leaves Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Leaves Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when booking. If you live in an older home near Keston Parish Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Leaves Green is about 4 miles south of Bromley, in Greater London. We visit Leaves Green as part of our work across Greater London, for houses, flats and commercial buildings. Leaves Green is one of the towns and villages in Greater London we cover for thermal roof surveys. There’s also a page for London.

The countryside around Leaves Green includes Nore Hill and West Kent Golf Course nature reserve.
What happens on the day
We look at the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes between one and two hours for a house; commercial roofs usually need 3–4 hours. In Leaves Green, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- Leave side gates unlocked
- If you’re buying, check with the agent that we can get in
- If the roof is shared, arrange access with whoever manages the building
