FAQs for Benhilton
Are there drone restrictions around Benhilton?
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. Before any flight, we check the Drone Safety Map for airspace restrictions. Strong wind or a downpour also stops a small drone flying.
How do I find out if my home in Benhilton is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will the camera show exactly where the water is?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
Does the weather affect a thermal survey?
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 talk through the forecast when booking.
How much does a thermal roof survey cost?
Our Premium Survey, from £400, includes thermal imaging. You also get an in-person consultation and a 12-month follow-up. Larger commercial roofs are quoted for their size.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
What happens next?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Thermal roof surveys for homes and businesses in Benhilton
Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where it applies, structural analysis and a report on the same day. There’s an in-person consultation as well, plus a follow-up 12 months later. To book, just call 07833 053749 or use the contact form with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. We survey pitched roof slopes, commercial roofs and insulated roof spaces, and common reasons people get in touch are water that travels before it shows and damp where roofs meet walls and chimneys.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. We take care to focus on the roof we have been asked to look at. Let us know about the building and access when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the roof, any defects and our written recommendations.

Thermal roof surveys in Benhilton: local notes
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Nonsuch Mansion, about 1.9 miles south-west, is one of the historic houses in the wider area around Benhilton. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
Controlled parking zones are common in London, so mention any permit rules for Benhilton, along with any off-street space. Anyone responsible for a site like All Saints Benhilton CofE Primary School will know that thermal images can show where wet insulation sits under a big flat roof.

What happens on the day
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes roughly 1–2 hours for a house; commercial roofs usually need 3–4 hours. In Benhilton, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- A thermal camera records how the surface temperature varies across the roof.
- 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.
How to prepare
- If the roof is shared, arrange access with whoever manages the building
- Find any records of previous roof work
- Have keys ready for side gates, garages or roof access doors
How to book
Getting a price is simple: just call 07833 053749 or use the contact form, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.

Signs you need a thermal roof survey in Benhilton
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
These are some of the problems a survey can pick up:
- Areas of a flat roof that may hold water
- Wet areas near outlets and upstands
- Areas losing heat at the eaves and junctions
- Cold areas below the roof
Shop and office owners around Centrale Croydon may find that a commercial roof can be photographed from above without anyone walking on it.
What to check before booking
- Whether any drone flown is registered with the CAA
- Are they insured for the work?
- Whether VAT is in the quoted price
- Which limits apply to the survey
DIY checks: what’s safe
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.

Different roofs, different checks
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
Felt and asphalt flat roofs
Felt and asphalt roofs often show wet areas as patches that differ from the rest. Moisture readings are used to check them.
Tips that help
There is plenty you can do without going near the roof. Here’s what helps most:
- Move stored items away from the loft hatch
- Clear leaves from outlets and gutters each autumn
- Talk to us about the weather when booking
- Don’t switch the heating off ahead of the visit
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. A follow-up 12 months later is included as well.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
