Thermal imaging roof survey in Telegraph Hill, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof in Telegraph Hill, using drones and thermal imaging where it applies. Call or email for a price.
- Missing or slipped insulation
- Damp around chimneys and parapets
- Damp around roof outlets and upstands
How a thermal roof survey works in Telegraph Hill
We present each thermal image next to a normal photo of the same area, so it is easy to see which part of the roof each one shows. We explain what each pattern may mean, what the moisture readings found and what we recommend. With a Premium Survey, the report reaches you the same day. If you have questions, the in-person consultation gives you time to go through them. A follow-up 12 months later is included too. We survey loft conversions, insulated roof spaces and flat roofs, and people most often book us about areas losing heat at the eaves and junctions and cold spots on ceilings under the roof.
Many London roofs are hidden from the pavement: valley gutters behind parapets, dormers and flat-roofed rear additions. That is 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 Telegraph Hill as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What a thermal roof survey looks like in Telegraph Hill
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
The streets around a church such as St Catherine's Hatcham are frequently among the oldest in a place, and if you own one of the older houses nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image. If you look after a building such as Haberdashers' Hatcham College, a view from above covers a wide roof far faster than walking it. If you look after a shop, office or commercial unit, for instance near Lewisham Shopping Centre, a commercial roof can be photographed from above without anyone walking on it.

Rented homes, blocks and businesses
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. Access is agreed with the tenant in advance.
Landlords and agents in Telegraph Hill book surveys as well as householders. The report gives you a dated record of the roof, with photographs, which helps you plan work between tenancies.
How the survey changes by roof type
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.

Practical tips
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Remember the conditions on the day affect the results
- File the images with your roof records
- Keep the heating on as usual before a heat loss survey
- Keep dated photos of any marks on ceilings
You also get an in-person consultation with a Premium Survey, giving you the chance to talk through the images and findings. A follow-up 12 months later is included as well.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.
What affects the price in Telegraph Hill
Our packages start from £150, including VAT. The price for your roof depends on:
- If the survey needs thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can be seen safely
- The size of the roof
Every price we give includes VAT, and the written report is part of the package. Our price is from £400, including VAT. Size, height and access decide where your roof falls.
What we need to know
You do not need to know any roofing terms. It’s enough to tell us:
- Any deadline, such as an exchange date
- The type of building and roof, such as pitched or flat
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or email us.
Telegraph Hill: your questions answered
Is parking a problem for a survey in Telegraph Hill?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Does a conservation area affect roof work in Telegraph Hill?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
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’s colder outside. We look from the loft as well, where there’s safe access.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
What can thermal imaging tell me about my roof?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Will you go up on the roof?
Only if it’s safe. We inspect whatever is safely visible: from ground level, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. Anything we cannot see is noted in the report.
Why get it checked now?
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. In Telegraph Hill, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
What you get with us
- PI and public liability insurance

Take a look at what a roof survey costs and what we found on two real jobs.
How the survey works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey typically takes roughly 1–2 hours for most houses, and about three to four hours for a commercial roof. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Telegraph Hill runs like any other.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Let us know where we can park nearby
- Have keys ready for side gates, garages or roof access doors
