Thermal imaging roof survey in Greenhill, Greater London
Thermal imaging to find moisture and heat loss patterns in a roof across Greenhill, with drones and thermal imaging where they help. Get in touch for a price.
- Water getting in at parapets and stacks
- Gaps in loft insulation
- Possible trapped moisture under a flat roof covering
What happens if roof problems are left?
Before replacing a large flat roof, it helps to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you commit. In Greenhill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. We confirm the price for your survey before booking.

About our thermal roof survey in Greenhill
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’ve noticed damp around chimneys and parapets and stains that keep coming back, a survey will tell you what’s going on, whatever the roof.
London roofs sit shoulder to shoulder in terraces and blocks, so privacy and neighbours matter as much as the view. We take care to focus on the roof we have been asked to look at. Tell us about the building and access when you book. The extra view helps most on steep slopes, tall stacks and rear additions.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

How it works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. In Greenhill, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when 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.
- 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
- If you’re buying, check with the agent that we can get in
- Make sure pets are kept safely away
- Let us know about any leaks, stains or damp patches you know of
Booking a survey
Every survey is priced before it’s booked, so you know where you stand. Our price is from £400, including VAT. To book, ring 07833 053749 or use the contact form.

Thermal roof surveys in Greenhill: local notes
Historic houses such as 2 Willow Road, about 0.3 miles north-east, show how far back building in the area around Greenhill goes. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. There are several hotels within about a mile and a half of Greenhill. If you look after one, a large roof can be surveyed without guests having anyone working above them.
The streets around a church such as Rosslyn Hill Unitarian Chapel are often among the oldest in a place, and if your home is one of the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image. Anyone responsible for a site like The Royal School will know that a view from above covers a wide roof far faster than walking it.
Greenhill is about 1 mile north-east of Hampstead, in Greater London. Roofs in Greenhill get the same thorough look as anywhere else in Greater London. Our Greater London coverage includes Greenhill and the places around it.
We survey roofs across the NW3 and NW6 postcode area for thermal roof surveys. That includes homes and businesses on Back Lane, Well Road and Ornan Road and the roads around them. If you’re just outside Greenhill, we cover Hampstead (1 mile south-west), Vale of Health (1 mile north), West Hampstead (1 mile west), Fortune Green (1 mile west) and Haverstock (1 mile south-east). We also work in nearby towns such as London (5 miles south-east), City of Westminster (3 miles south), Marylebone (3 miles south-east), Kensington (4 miles south), St Pancras (3 miles south-east) and Shoreditch (5 miles south-east).
Landmarks near Greenhill
We work in homes and buildings around Cecil Sharp House, Fitzjohn's Primary School and King William IV Public House, among other places. Nearby too are South Hampstead High School (0.6 miles south) and Hampstead Heath (0.7 miles north-east). There is a railway station in Greenhill itself: Hampstead Heath station. Well-known places in the area include New End Hospital (less than half a mile north-west) and Montfichet's Tower (4.3 miles south-east). The countryside around Greenhill includes Belsize Wood and Parliament Hill.
When to book a survey in Greenhill
Some defects simply can’t be seen with the eye. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. Thermal imaging gives us another way to look for them.
Here are some of the things we see often:
- Damp patches with no obvious cause
- Cold spots on ceilings under the roof
- Possible trapped moisture under a flat roof covering
- Thin or uneven insulation in the roof
For hotels and guest houses around Greenhill, a roof problem found early is far less disruptive than one found by a guest.
Before you book anyone
- Is there a chance to talk the report through?
- How long the report takes to arrive
- Which parts of the roof they’ll actually see
- What exactly goes into their report
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
How we price thermal roof surveys
Prices vary from roof to roof, and it comes down to:
- The package you choose: Basic, Standard or Premium
- Any need for thermal images or a drone flight
- Roof area
- Extra roofs, like extensions, dormers or garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Our price is from £400, including VAT.
What we need to know
If you can, have these to hand when you get in touch:
- Your postcode, so we can check access and travel
- Dates you are working to, like exchange
- What’s prompted the survey
- Any marks or damp showing indoors
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.
Your questions about thermal roof surveys in Greenhill
Can parking be tricky for a visit in Greenhill?
Usually it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Is my home in Greenhill listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
How long will you be at the property?
Expect it to take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. You will then get the report by email.
Can a thermal survey trace a roof leak?
It frequently helps show where to look. Patterns can suggest where trapped water has spread. It’s used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
When you need someone else
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- A structural engineer’s assessment
- An energy rating for the building
- Seeing water directly, as the camera shows temperature, not moisture
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer before you book. The full list of what we check.
What we look at
