Thermal roof surveys for homes and businesses in Blackfriars
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. It is important to know that the camera shows temperature, not water, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’ve noticed ceilings that feel colder in places and thin or uneven insulation in the roof, a survey will tell you what’s going on.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. Images are taken to show the roof we’re surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building when you book. The extra view helps most on steep slopes, tall stacks and rear additions.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put with the most urgent first where relevant.

How the survey works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. It typically takes about one to two hours for most houses, 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 Blackfriars moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- First we discuss the roof, any damp and the forecast for the visit.
- 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

How we price thermal roof surveys
Prices vary from roof to roof, and it comes down to:
- The roof’s overall size
- Whether thermal imaging or a drone is needed
- Whether you choose the Basic, Standard or Premium Survey
- The type of building, from a house to a block or an office
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both with VAT included. You’ll know the price for the job before booking.
What we need to know
The more you tell us, the easier it is to price the survey. When you contact us, let us know:
- The style of property, from a terrace to a block
- The property’s address and postcode
- Dates you are working to, such as exchange
- The reason for the survey, like buying, a leak or storm damage
To get a price for thermal roof surveys in Blackfriars, ring 07833 053749 or use the contact form. Some details about the property and the roof help us price the survey accurately.
How the survey changes by roof type
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.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. The report explains what the images can tell you and what they can’t.
Common questions in Blackfriars
Is my home in Blackfriars listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Blackfriars?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Do you work in Blackfriars?
Yes. We cover Blackfriars and the rest of Greater London, as part of our work across London and the South East. To book, phone 07833 053749 or drop us an email.
Are you insured?
Our cover is professional indemnity plus public liability, and details are available on request.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.
Which survey includes thermal imaging?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. Larger commercial roofs are quoted for their size.
How do I arrange a thermal roof survey in Blackfriars?
Just call 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day.
Why act early in Blackfriars
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. 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.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Why book us in Blackfriars

What a thermal roof survey does not cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Confirming water without moisture readings
- The condition of timbers we can’t see
- Structural calculations, which need a structural engineer
If in doubt, call 07833 053749 or send us an email and we will point you to the right survey. What a survey covers and doesn’t.
What this survey covers
- Flat roofs
- Pitched roof slopes
- Insulated roof spaces
- Commercial roofs
- Loft conversions
- Ceilings below the roof
For landlords and managing agents
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.

There are several hotels within about a mile and a half of Blackfriars. For hotels and other commercial buildings, large roofs are where photos from the air and thermal images show the most at once. Blackfriars is about 1 mile from the restricted area over the City of London, where drone flights need permission from NATS. Where the drone is part of the survey, we check whether the address falls inside it before flying.
If you live in an older home near St Ann Blackfriars, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view by drone or thermal camera helps. Shop and office owners around Gabriel's Wharf may find that a commercial roof can be photographed from above without anyone walking on it. Controlled parking zones are common in London, so mention any permit rules for Blackfriars.
