Thermal imaging roof survey in Mill Hill, Greater London
We carry out thermal roof surveys in Mill Hill and the rest of Greater London. We survey on weekdays, Saturdays and Sundays.
- Missing or slipped insulation
- Leaks that are hard to trace
- Damp around roof outlets and upstands
Signs you need a thermal roof survey in Mill Hill
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. The camera helps narrow the search.
Most people get in touch when they’ve noticed one of these:
- Damp around chimneys and parapets
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
- Leaks far from where the stain appears
For a London address like Mill Hill, it is useful to know about controlled parking before the day, along with any off-street space.
Questions to ask before booking
- How soon the report will arrive
- Their insurance cover
- Whether the loft space is looked at, where there is one
- What happens after the report arrives
Thermal roof surveys for homes and businesses in Mill 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. There is a 12-month follow-up as well. We survey flat roofs, pitched roof slopes and ceilings below the roof, and common reasons people get in touch are wet insulation beneath the membrane and ceilings that feel colder in places.
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. Every address in Mill Hill is checked before any drone flight, and where permission is needed, the flight waits for it.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Questions from Mill Hill
Are there drone restrictions around Mill Hill?
Normally it comes down to two things: the airspace at the address and the weather. 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. Every flight is checked against the Drone Safety Map first. A small drone can’t fly safely in high wind or heavy rain, though the rest of the survey goes ahead either way.
How do I find out if my home in Mill Hill is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
What do I do with the report?
You’ll get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
How do I book a survey in Mill Hill?
Just ring 07833 053749 or drop us an email. We will ask a few questions, confirm the price and agree a date.
Do you cover Mill Hill?
Yes. We survey roofs in Mill Hill and the rest of Greater London. To book, phone 07833 053749 or drop us an email.
Can a thermal survey trace a roof leak?
It’s 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 will say what could help next, such as electronic leak detection.
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where applicable.
What affects the price in Mill Hill
Several things affect the price of a survey:
- Which survey package you book
- How tall the building is and how easy the roof is to see
- How complicated the roof is, with its valleys, chimneys and parapets
- Commercial roofs and larger buildings
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 inc. VAT. We’ll tell you which package suits the questions you have.
Helping us price your survey
When you call or email, these details help:
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
- Anything about access we should know
- The style of property, from a terrace to a block
Most bookings start with a short call: call 07833 053749 or use the contact form and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
Why get it checked now?
A damp patch that keeps coming back typically has a cause that hasn’t been found. Combining the camera with moisture readings can help find it, instead of trying repair after repair. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Thermal roof survey starts from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT.
Why us?
- Clear package prices, with VAT included
- 98% customer satisfaction

What we do, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. The whole visit typically takes about one to two hours at most homes, rising to roughly 3–4 hours on a commercial building. For a visit in Mill Hill, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at whatever is safely visible from ground level, windows, the loft and, where it is safe, the roof itself.
- 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.
Before we arrive
- Check pets are kept safely away
- Dig out any old roof reports or invoices
- Have any questions written down, so nothing gets missed

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Keep the heating on as usual before a heat loss survey
- Clear leaves from outlets and gutters each autumn
- Do not climb onto the roof to look for leaks yourself
- Keep the report to compare against after any repair
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There’s a 12-month follow-up too.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
Airspace, weather and Mill Hill roofs
With Heath Hall about 4 miles south-east, Mill Hill sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If yours is one of the older homes in the streets near St Paul's Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Anyone responsible for a site like St Paul's CofE Primary School NW7 will know that thermal images can show where wet insulation sits under a big flat roof.
