Thermal roof surveys for homes and businesses in Sudbury Hill
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. It works best when the building is heated and it’s colder outside. Our report points out what the images suggest and where to look more closely. It is not an energy rating or a heat loss calculation. We survey loft conversions, flat roofs and pitched roof slopes, and common reasons people get in touch are water that travels before it shows and missing or slipped insulation.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every address in Sudbury Hill is checked before any drone flight, and permission is never taken for granted.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Seeing water directly, as the camera shows temperature, not moisture
- Readings unaffected by sun, shade or reflections
- Hidden layers that need to be opened up to check

Useful tips for Sudbury Hill property owners
A survey works best with a little help from you, before and after. Some tips:
- Ask us about the forecast if rain is expected
- Let us know where and when you’ve seen damp or stains
- Clear a path to the loft hatch before we arrive
- Heat the home normally on the days before
Where a pattern can’t be confirmed, the report says what could help, for example electronic leak detection or a roofer opening up a small section.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
What you can safely check yourself
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
What affects the cost of thermal roof surveys
A few things affect what a survey costs:
- If the survey needs thermal imaging or a drone
- Whether it’s a home or a commercial building
- The size of the roof
- The package you choose: Basic, Standard or Premium
To find out what your survey will cost, ring 07833 053749 or send us an email with the address and a few details. We will confirm the figure before booking.

- Dates you are working to, such as exchange
- What’s prompted the survey
- Pictures from the garden or a window, if you have them

What happens on the day
The visit typically starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In Sudbury Hill, 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, tell us when booking.
- We start with the roof, its history and any signs of damp or heat loss.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
- Mention any parking restrictions on your street

Sudbury Hill questions
Can parking be tricky for a visit in Sudbury Hill?
Sometimes, yes. If Sudbury Hill has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Can you fly a drone over a roof in Sudbury 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. Every London address is checked against them before a flight. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
How long will you be at the property?
It usually takes about 1–2 hours for a house, with bigger or more complicated roofs taking longer. The report follows by email.
What happens next?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What conditions are best for thermal imaging?
Conditions on the day affect the results. It works best after a sunny day, with a dry roof surface and little wind. Rain and strong wind can make the images less clear, so we discuss the forecast when booking.
Can thermal imaging show missing insulation?
Gaps and thin areas of insulation can show up on the camera. It shows most clearly when it’s warm inside and cold outside. We look from the loft as well, where there is safe access.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.

Leave it or get it looked at?
Heat lost through a roof costs money every winter. The camera can point to gaps and thin areas in the insulation, so you know where to put things right. In Sudbury 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.
Every price we give includes VAT, and the report is not charged as an extra. Thermal roof survey starts from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Drones, thermal imaging and Sudbury Hill roofs
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help. There are several hotels within about a mile and a half of Sudbury Hill. For hotels and other commercial buildings, large roofs are where close-up aerial shots and thermal images show the most at once.
Hotels and guest houses near Sudbury Hill cannot easily close rooms for a leak, so it’s worth knowing the roof’s condition. Controlled parking zones are common in London, so mention any permit rules for Sudbury Hill. With Northolt Manor about 2.2 miles west, the area around Sudbury Hill has a long history. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition.
