Thermal roof survey in Canons Park: what you get
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. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. A follow-up 12 months later is included too. Typical surveys look at cold spots on ceilings under the roof and areas of a flat roof that may hold water, across loft conversions, flat roofs and ceilings below the roof.
In London’s terraces and conversions, roofs are packed close together, 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, in Canons Park as anywhere. Mention access, height and anything unusual about the building as you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. You are welcome to ask questions while we are there. For a visit in Canons Park, 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. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Keep pets out of the way during the survey
- Jot down any questions you want answered
- Show us where any leaks or stains appear

Why get it checked now?
If a big flat roof may need replacing, knowing the wet areas first is useful. Images backed by moisture readings show where problems seem to be before you spend. In Canons Park, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Every price we give includes VAT. Thermal roof survey starts from £400, including VAT. We confirm the exact price before booking.

Common questions in Canons Park
Will parking be an issue for a roof survey in Canons Park?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Is drone flying allowed in Canons Park?
Usually it comes down to two things: the airspace at the address and the weather. Across London there are restriction zones around Heathrow, London City and London Heliport, plus 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. Strong wind or heavy rain also stops a small drone flying, and the rest of the survey doesn’t depend on the drone.
How long will you be at the property?
It typically takes an hour or two at most homes, with bigger or more complicated roofs taking longer. We’ll confirm the timing when you book.
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 is colder outside. Where we can reach the loft safely, we check there too.
Does thermal imaging work on slate and tile roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
What affects the cost of thermal roof surveys
Prices always include VAT. The things that change the price are:
- Whether you choose the Basic, Standard or Premium Survey
- If the survey needs thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- How tall the building is and how easy the roof is to see
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400. You’ll know the price for your survey before booking.
Getting in touch
Some details help us point you to the right survey and price. When you get in touch, it helps to mention:
- Why you want a survey: buying, a leak, a storm or new work
- Your postcode, so we can check access and travel
- Where any leaks, stains or damp patches show inside
- Pictures from the garden or a window, if you have them
Unsure which package suits your roof? It is easiest to call 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll explain the options and the price.

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we look at the roof.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
What a thermal roof survey looks like in Canons Park
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Canons Park is one of them, bay roofs, hips and later dormers each have their own details. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
Take a building like Camrose Primary With Nursery: a view from above covers a wide roof far faster than walking it. Shop and office owners around Broadwalk Centre may find that big, flat commercial roofs are where aerial photos and thermal images help most.

What we’re asked to look at in Canons Park
Buyers sometimes want more than a visual look at the roof. The Premium Survey brings thermal imaging and a drone inspection where applicable, with a report the same day, which suits a purchase that’s moving quickly.
Look out for signs like these:
- Damp where roofs meet walls and chimneys
- Water that travels before it shows
- Damp patches with no obvious cause
- Areas of a flat roof that may hold water
Headstone Manor, about 3 miles west, is one of the historic houses in the wider area around Canons Park. A drone or thermal survey does not involve any work on the roof, which suits older buildings.
Before you book any roof surveyor
- Are they insured for the work?
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What the survey won’t cover
- Will the report include photos?
How the survey changes by roof type
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below frequently show. Reflections from shiny surfaces can affect readings, which we allow for.
