Thermal Roof Survey in Bentley Heath
We carry out thermal roof surveys in Bentley Heath and the rest of Greater London. We survey on weekdays and at weekends.
- Moisture around outlets and upstands
- Water that travels before it shows
- Damp that repairs haven’t cured
When you need someone else
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- The condition of timbers we cannot see
- Structural calculations, which need a structural engineer
- Clear results when the conditions on the day are poor
Not sure which survey suits your roof? You can ring 07833 053749 or email us and we will tell you before booking. What a survey covers and doesn’t.
Roof types and parts we check

Thermal roof survey in Bentley Heath
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. We explain what each pattern may mean, what the moisture readings found and what we recommend. With a Premium Survey, the report reaches you the same day. If you have questions, the in-person consultation gives you time to go through them. There is a 12-month follow-up as well. We survey insulated roof spaces, flat roofs and ceilings below the roof, and the problems we’re asked to look at most are leaks that are hard to trace and ceilings that feel colder in places.
Many London roofs are hidden from the pavement: valley gutters behind parapets, dormers and flat-roofed rear additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. The weather decides the day: both drones and thermal cameras need the right conditions. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Tips that help
Nothing here needs a ladder. Our suggestions:
- Use the report as a baseline for later checks
- Don’t climb onto the roof to look for leaks yourself
- Keep dated photos of any marks on ceilings
- Don’t switch the heating off before the visit
After the visit, we put the thermal images, photos and moisture readings into one report. We explain what each image may mean, with our recommendations. Premium reports are sent the same day.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
FAQs for Bentley Heath
Will parking be an issue for a roof survey in Bentley Heath?
It rarely stops a survey, but it is worth planning. Let us know what parking is available nearby, and the visit is planned around it.
Are there drone restrictions around Bentley Heath?
That depends on where the roof is and on 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. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. A small drone can’t fly safely in high wind or heavy rain, though the rest of the survey goes ahead either way.
Do you cover Bentley Heath for thermal roof surveys?
Yes, we do. We carry out thermal roof surveys in Bentley Heath, and the service is the same as everywhere else we work.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
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 can’t tell you, and we check them with a visual inspection and moisture readings.
What happens next?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
Common roof problems in Bentley Heath
Some defects simply can’t be seen with the eye. Wet insulation, gaps in insulation and heat loss are often invisible from outside. A thermal camera adds another way of finding them.
People usually book a survey after spotting one of these:
- Possible trapped moisture under a flat roof covering
- Patches of heat loss across the roof
- Stains that keep coming back
- Damp around chimneys and parapets
As a London address, Bentley Heath can be tricky for parking: let us know about parking bays, permits or a driveway as you book, as a space near the door can’t be promised.
Before you book anyone
- Will they check the loft as well as the outside?
- Whether the price includes VAT
- Their drone registration, if they fly one
- How they’ll see the roof: from ground level, the loft, the roof or by drone
Landlords, agents and block managers in Bentley Heath
Landlords and letting agents in Bentley Heath book surveys as well as homeowners. The report gives you a dated record of the roof, with photographs, which helps you plan work between tenancies.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
Drones, thermal imaging and Bentley Heath roofs
The wider area around Bentley Heath has a long history of building, with Wyllyotts Manor about 0.9 miles north. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in 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. 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 businesses in and around places like Spires Shopping Centre, a commercial roof can be photographed from above without anyone walking on it. If you look after a building such as Pope Paul Catholic Primary School, a drone or thermal camera can show a large roof in a single visit.

Why act early in Bentley Heath
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 inc. VAT. We can help you choose the package that fits what you’d like to know.

The survey, step by step
Once we have finished looking, we write up our findings in a report with photographs, sent to you by email. As for time on site, it usually takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. Surveys in Bentley Heath can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- 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.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Make sure pets are kept safely away
- Agree roof access with the managing agent if it’s shared
- Let us know about any leaks, stains or damp patches you know of
