Thermal imaging roof survey in Farringdon, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof in Farringdon. More than 5,000 surveys completed across London and South East England.
- Damp that repairs haven’t cured
- Areas losing heat at the eaves and junctions
- Cold areas below the roof
Honest limits
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Reliable images in rain, strong wind or on a wet roof surface
- A structural engineer’s assessment
- Confirming water without moisture readings
If in doubt, phone 07833 053749 or drop us an email and we’ll recommend the right survey before you book. The full list of what we check.
Roofs we survey in Farringdon
- Flat roofs
- Insulated roof spaces
- Commercial roofs
- Loft conversions

Thermal roof surveys for homes and businesses in Farringdon
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, something you cannot normally tell from the surface. We then check those areas with moisture readings. If you’re worried about areas of a flat roof that may hold water and water that travels before it shows, a survey will tell you what’s going on.
Many London roofs are hidden from the pavement: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. That’s where a view from the air or a thermal camera helps, by showing what can’t be reached safely. Weather on the day decides whether it goes ahead, in Farringdon as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Common questions in Farringdon
Can parking be tricky for a visit in Farringdon?
Sometimes, yes. If Farringdon has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in Farringdon is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Are you structural engineers?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
Do you need a thermal roof survey in Farringdon?
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so we know where to take moisture readings.
We are often asked to look at:
- Damp around roof outlets and upstands
- Thin or uneven insulation in the roof
- Possible trapped moisture under a flat roof covering
- Water that travels before it shows
If yours is one of the older homes in the streets near St John Clerkenwell, thin or patchy insulation under an old roof often shows up clearly on a thermal image.

Thermal roof surveys in Farringdon: local notes
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. There are several hotels within about a mile and a half of Farringdon. For hotels and other commercial buildings, large roofs are where aerial photos and thermal images show the most at once.
If you look after a shop, office or commercial unit, for example near Gabriel's Wharf, a commercial roof can be photographed from above without anyone walking on it. Take a building like Charterhouse Square School: a view from above covers a wide roof far faster than walking it.
Farringdon is about 2 miles north of London, in Greater London. We survey roofs in Farringdon and the surrounding area as part of our work across London and South East England. Farringdon is one of the places in Greater London where we work for thermal roof surveys.

DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes an hour or two on an ordinary house, though large, tall or awkward roofs take more time. 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 as you book.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Tell us about parking before the day
- Leave a clear route to the loft
How to book

Advice
Why it’s worth a survey now in Farringdon
Repeated repairs that do not stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, rather than more guesswork. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Prices start from £400, including VAT. The final price depends on how big and how high the roof is, how it can be seen safely and which survey you book.

How we price thermal roof surveys
Not every roof costs the same to survey, for these reasons:
- House, block, shop or office
- How big the roof is

Most bookings start with a short call: phone 07833 053749 or send us an email. The price is agreed before a date is set.
