Thermal imaging roof survey in South Street, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof across South Street, using drones and thermal imaging where it applies. Call or email for a price.
- Damp around roof outlets and upstands
- Damp where roofs meet walls and chimneys
- Leaks that are hard to trace
What happens if roof problems are left?
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400. You will know the price for the job before booking.

How a thermal roof survey works in South Street
A thermal survey is not a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. If a finding cannot be confirmed, the report suggests a next step. We are frequently asked to look into thin or uneven insulation in the roof and damp that repairs haven’t cured, on loft conversions, insulated roof spaces and commercial roofs.
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 South Street is checked before any drone flight, and permission is never taken for granted.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Useful tips for South Street property owners
You do not need to be a roofer to help. What helps most:
- Photograph damp patches with the date
- Move stored items away from the loft hatch
- Note where damp appears and after what weather
- Heat the home normally on the days before
Buyers can use the findings when talking to the seller or agent. It’s your decision how to use it, whether you ask for work before completion or discuss the price.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
Common questions in South Street
Can parking be tricky for a visit in South Street?
Parking in South Street, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Does a conservation area affect roof work in South Street?
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.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Mention it when you contact us and we will explain what’s needed.
Do you work in South Street?
Yes. We survey roofs in South Street and the rest of Greater London. To book, phone 07833 053749 or email us.
How do I arrange a thermal roof survey in South Street?
Just ring 07833 053749 or email us. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
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.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
How the survey works
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. Most visits take roughly 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- 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’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Mention any parking restrictions on your street
- Let us know about any leaks, stains or damp patches you know of
- Buyers: confirm access with the estate agent or seller
Getting a price
A quick phone call is usually the easiest start: ring 07833 053749 or send us an email, and we will ask about the building and what you need. You’ll have a price before anything is arranged.

Roof by roof
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Shiny surfaces can reflect heat, so we take care reading the images.
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. We combine a close visual check with the thermal images.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Hidden layers that need to be opened up to check
- Whether the deck or roof structure is strong enough
- Confirming water without moisture readings
If in doubt, phone 07833 053749 or email us and we’ll recommend the right survey. The full list of what we check.
What this survey covers
- Loft conversions
- Flat roofs
- Commercial roofs
- Pitched roof slopes
- Ceilings below the roof

What a thermal roof survey looks like in South Street
South Street is about 3 miles from Biggin Hill Airport. Where the drone is part of the survey, the Drone Safety Map is checked for restrictions first. Titsey Place, about 2.1 miles south-west, is one of the historic houses in the wider area around South Street. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
For an older house near a landmark such as Church of St Mary the Virgin, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. South Street is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier. Anyone responsible for a site like Charles Darwin School will know that thermal images can show where wet insulation sits under a big flat roof.
South Street is about 4 miles north-east of Oxted, in Greater London. In South Street, as across Greater London, every roof gets the same careful survey. South Street is one of the places in Greater London we cover. There is also a page for London.

What affects the cost of thermal roof surveys
A few things affect what a survey costs:
- The package you choose: Basic, Standard or Premium
