Thermal roof survey in Roxeth: what you get
Thermal imaging is a useful tool, but it has limits. Sun, shade, reflective surfaces and wind can all change what the camera shows. That is why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. Where something cannot be confirmed, we say what would help next. If you’ve noticed heat escaping through the roof and damp around chimneys and parapets, we can find out what’s behind it.
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 Roxeth is checked before any drone flight, and where permission is needed, the flight waits for it.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

Why it is worth a survey now in Roxeth
A poorly insulated roof loses heat year after year. The camera can point to gaps and thin areas in the insulation, so improvements can go where they’re needed. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

Tips from our surveys
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Keep the report to compare against after any repair
- Keep the heating on as usual before a heat loss survey
- Tell us where and when you’ve seen damp or stains
- Talk to us about the weather when booking
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Insulation is often moved when people work in the loft space.
How we price thermal roof surveys
Prices always include VAT. The things that change the price are:
- Roof area
- Commercial roofs and larger buildings
- Chimneys, valleys, parapets and other details
- The package you choose: Basic, Standard or Premium
Thermal roof survey starts from £400, including VAT. What you pay depends on the size and height of the roof, how it can safely be seen and the package you choose.
What to tell us when you get in touch
There’s no need for technical words. It is enough to tell us:
- Photos of the roof, taken safely from the ground or a window
- What’s prompted the survey
- Your timetable, such as an exchange date
- The kind of building and roof involved
When you’re ready to go ahead, ring 07833 053749 or send us an email. We’ll suggest a package, agree the price and find a date.

How it works
We will ask a few questions first, like when any problem began and what work has been done before. The inspection then takes roughly 1–2 hours at a typical home, rising to roughly 3–4 hours on a commercial building. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- We take thermal images of the roof to pick up temperature patterns.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Unlock side gates and any roof access doors
- Tell us about any leaks, stains or damp patches you know of
- Leave a clear route to the loft

Advice
Roxeth questions
Are there drone restrictions around Roxeth?
Typically 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. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first. Strong wind or a downpour also stops a small drone flying, though the rest of the survey goes ahead either way.
Is parking a problem for a survey in Roxeth?
Parking in Roxeth, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Does thermal imaging work on slate and tile roofs?
It can be useful, though pitched roofs are usually harder to read. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there’s safe access.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
How long is the visit?
Time on site depends on the roof; most visits take about one to two hours at a typical home, while a commercial roof takes nearer three to four hours. The written report follows by email.
Will the camera show exactly where the water is?
The camera does not see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Thermal roof surveys in Roxeth: local notes
The wider area around Roxeth has a long history of building, with Northolt Manor about 1.9 miles south-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. 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 close-up aerial shots and thermal images help.
For site and facilities teams at buildings like Roxeth Primary School, big roofs are where close-up aerial shots and thermal images show the most at once. If yours is one of the older homes in the streets near Christ Church, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Roxeth is about 1 mile south of Harrow, in Greater London.

Signs you need a thermal roof survey in Roxeth
On big commercial and residential flat roofs, thermal imaging helps owners plan. It can suggest which areas may be wet and which seem dry, so we know where to take moisture readings.
Signs worth acting on include:
- Thin or uneven insulation in the roof
- Areas of a flat roof that may hold water
- Cold spots on ceilings under the roof
- Heat escaping through the roof
Controlled parking zones are common in London, so mention any permit rules for Roxeth, along with any off-street space.
