Airspace, weather and Brentford roofs
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Brentford has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a large roof can be surveyed without guests having anyone working above them.
Historic houses such as Kew Palace, about 0.5 miles south-east, show how far back building around Brentford goes. A drone or thermal survey does not involve any work on the roof, which suits older buildings. If you look after a shop, office or commercial unit, for example near Treaty Centre, thermal images can show trapped moisture across a wide commercial roof. Controlled parking zones are common in London, so mention any permit rules for Brentford.

How a thermal roof survey works in Brentford
Thermal imaging is part of our Premium Survey, which starts from £400. It also includes a drone inspection where applicable, a structural analysis and a same-day report. An in-person consultation and a 12-month follow-up are included too. You can call 07833 053749 or email us with the address and a note of what you’ve noticed. For big commercial roofs, we quote on size and access. Common reasons to book are gaps in loft insulation and areas of a flat roof that may hold water, across flat roofs, pitched roof slopes and loft conversions.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. Images are taken to show the roof we are surveying, with care for neighbours’ privacy, in Brentford as anywhere. Let us know about the building and access as you book. The extra view helps most on steep slopes, tall stacks and rear additions.
Where we can’t see part of the roof, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Different roofs, different checks
Felt and asphalt flat roofs
Felt and asphalt roofs frequently show wet areas as patches that differ from the rest. We check those patches with moisture readings.
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
Leave it or get it looked at?
Before replacing a large flat roof, it is useful to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you commit. Any roof job in Brentford means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan.
Every price we give includes VAT, and the written report is part of the package. Prices start from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Your questions about thermal roof surveys in Brentford
Is drone flying allowed in Brentford?
Typically 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. 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, though the rest of the survey goes ahead either way.
Will parking be an issue for a roof survey in Brentford?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show, so you can see what we mean.
Is thermal imaging useful on pitched roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.

What else we do in Brentford
Before and after the survey
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Check outlets after heavy rain
- Photograph damp patches with the date
- Do not climb onto the roof to look for leaks yourself
- Talk to us about the weather when booking
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
How it works
On the day, we start by asking what you’ve noticed and what you need to know. After that, we check everything we can see safely. Most surveys take about 1–2 hours for a house, and more on a big or complicated roof. 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 you book.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Let us know about parking near the property
- Dig out any old roof reports or invoices
- For a flat or shared roof, check access with the building owner or managing agent
How to book
When you are ready to go ahead, phone 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.

Landlords, agents and block managers in Brentford

A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
What we cannot see
Without opening up the roof, some things stay hidden, and that sets some limits:
- An energy rating for the building
- Whether the deck or roof structure is strong enough
- What’s inside walls or under coverings, without opening up
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer. What our survey covers.
