Sidcup Thermal Roof Survey

Thermal roof surveys for homes and businesses in Sidcup
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. We then check those areas with moisture readings. We survey ceilings below the roof, flat roofs and pitched roof slopes, and the problems we’re asked to look at most are gaps in loft insulation and damp around roof outlets and upstands.
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 Sidcup is checked before any drone flight, and permission is never taken for granted.
If any part of the roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Can I check my roof myself?
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Useful tips for Sidcup property owners
Nothing here needs a ladder. Our suggestions:
- Photograph damp patches with the date
- Ask us about the forecast if rain is expected
- Heat the home normally on the days before
- Do not climb onto the roof to look for leaks yourself
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Consider a repeat survey after major work on the roof in suitable weather.
How it works
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will take it from there. A typical survey takes about 1–2 hours at a typical home, rising to roughly 3–4 hours on a commercial building. For a visit in Sidcup, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Note where any stains or damp appear
- Unlock side gates and any roof access doors
How to book
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or drop us an email.
Advice
When to book a survey in Sidcup
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there is a clear difference between inside and outside.
We’re frequently asked to look at:
- Damp where roofs meet walls and chimneys
- Possible trapped moisture under a flat roof covering
- Damp around roof outlets and upstands
- Cold spots on ceilings under the roof
Shop and office owners around Broadway Shopping Centre may find that a commercial roof can be photographed from above without anyone walking on it.
What to check before booking
- Which viewpoints they use to see the roof
- Is VAT included in the price?
- How soon the report will arrive
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID

How we price thermal roof surveys
The price reflects the time and kit the roof needs. That comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
- The height of the building and how the roof can be seen safely
Thermal roof survey starts from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we can help you choose.

Thermal roof surveys in Sidcup: local notes
If your survey includes the drone, the flight is checked against the Drone Safety Map first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Sidcup is one of them, bay roofs, hips and later dormers each have their own details. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
For a London address like Sidcup, it is useful to know about controlled parking before the day. If you live in an older home near Holy Trinity Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.

Your questions about thermal roof surveys in Sidcup
Can you fly a drone over a roof in Sidcup?
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. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. A small drone can’t fly safely in strong wind or heavy rain, and the rest of the survey doesn’t depend on the drone.
Will parking be an issue for a roof survey in Sidcup?
It can be, so it is useful to tell us about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Can you survey at the weekend?
We carry out surveys on any day of the week. To find a day that suits you, phone 07833 053749 or send us an email.
What conditions are best for thermal imaging?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Will you go up on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
What happens if roof problems are left?
A damp patch that keeps coming back usually has a cause that hasn’t been found. Combining the camera with moisture readings can help find it, instead of trying repair after repair. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, including VAT. We can help you choose the package that fits what you’d like to know.
