Why it’s worth a survey now in Roundshaw
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Looking now, while the damage may still be limited, keeps more options open. In Roundshaw, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Prices start from £150, with VAT included, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for the job before booking.
What you get with us
- Insured for professional indemnity and public liability
- Independent findings on the roof’s condition
- Package prices that include VAT
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID

Thermal roof survey in Roundshaw
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging frequently helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. Common reasons to book are water that travels before it shows and stains that keep coming back, across pitched roof slopes, loft conversions and ceilings below the roof.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Before a drone goes up in Roundshaw, the address is checked against all of them, and permission is never taken for granted.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Your questions about thermal roof surveys in Roundshaw
Are there drone restrictions around Roundshaw?
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. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Does a conservation area affect roof work in Roundshaw?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Are you insured?
We hold professional indemnity and public liability insurance.
How long will you be at the property?
It usually takes about 1–2 hours at most homes; commercial roofs usually need 3–4 hours. The report follows by email.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Will thermal imaging find my leak?
It’s a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. If the source can’t be confirmed, we’ll say what could help next, such as electronic leak detection.
Do you work in Roundshaw?

DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Tips that help
You don’t need to be a roofer to help. What helps most:
- Do not switch the heating off before the visit
- Clear leaves from outlets and gutters each autumn
- Check from the ground or a window, never by climbing
- Take photos of stains as they appear, so we can compare
Once we’ve been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Drones, thermal imaging and Roundshaw roofs
Addington Palace, about 3.9 miles east, is one of the historic houses in the wider area around Roundshaw. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
Parking in Roundshaw, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised. For hotels and guest houses around Roundshaw, a roof problem found early is far less disruptive than one found by a guest. If your home is one of the older ones in the streets near St. Paul's, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.

What happens on the day
The visit has one job: to look at the roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit usually takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. In a London area like Roundshaw, the main things to sort out are parking and access: 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 the ground, from windows, from inside the loft space and from the roof where it’s safe.
- 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.
- A thermal camera records how the surface temperature varies across the roof.
- We check the patterns that stand out with moisture readings where there is safe access.
- You get a report with thermal images, photographs and our recommendations.
Before we arrive
- Unlock side gates and any roof access doors
- Show us where any leaks or stains appear
- Mention any parking restrictions on your street

What this survey cannot tell you
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Insulation values or heat loss calculations
- Whether the deck or roof structure is strong enough
- Hidden layers that need to be opened up to check
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we’ll tell you. What our survey covers.
What we check
- Flat roofs
- Loft conversions
- Commercial roofs
- Insulated roof spaces
- Ceilings below the roof
- Pitched roof slopes
Roof by roof
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. The camera can give clues to where it’s sitting, when the conditions allow.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
