Erith Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof across Erith, with drones and thermal imaging where they help. Call or email for a price.
- Water getting in at parapets and stacks
- Patches of heat loss across the roof
- Ceilings that feel colder in places
How a thermal roof survey works in Erith
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. You can talk the findings through with us at the in-person consultation. A follow-up 12 months later is included too. Common reasons to book are water that travels before it shows and stains that keep coming back, on pitched roof slopes, loft conversions and ceilings below the roof.
London’s roofs are often hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That is where a view from the air or a thermal camera helps, by showing what cannot be reached safely. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
Where we cannot 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.

Checking the roof from ground level
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.

The survey, step by step
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take between one and two hours on an ordinary house, and about three to four hours for a commercial roof. In a London area like Erith, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- 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’s safe access.
- You get a report with thermal images, photographs and our recommendations.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work
- Unlock side gates and any roof access doors
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.

How we price thermal roof surveys
When we price a survey, we consider:
- How many separate roofs there are, like extensions, dormers and garages
- Building height and the viewpoints available
- The size of the roof
- Commercial roofs and larger buildings
Prices quoted always include VAT, and the written report is part of the package. Our price is from £400, including VAT. Size, height and access decide where your roof falls.
What to tell us when you get in touch
What helps most when you contact us:
- The property’s address and postcode
- Dates you are working to, such as exchange
- The type of building and roof, like pitched or flat
- Anything about access we should know
For a price for thermal roof surveys in Erith, ring 07833 053749 or send us an email. The address, the type of property and what you want to find out help us price the survey accurately.
Questions from Erith
Are there drone restrictions around Erith?
That depends on where the roof is and on the weather. The flight restriction zone around London City Airport comes within about 2 miles of Erith. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. 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. Strong wind or a downpour also stops a small drone flying.
Is parking a problem for a survey in Erith?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. We’ll talk about access when you book.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
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.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Common roof problems in Erith
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. Thermal images and moisture readings together can show the likely extent.
Problems we come across frequently include:
- Heat escaping through the roof
- Missing or slipped insulation
- Water getting in at parapets and stacks
- Areas of a flat roof that may hold water
For businesses in and around places like Broadway Shopping Centre, large commercial roofs are often easiest to see from the air or with a thermal camera.
What to check before booking
- How long they’ve been surveying roofs
- Their drone registration, if they fly one
- What happens after the report arrives
- Whether they hold professional indemnity and public liability insurance
Roof by roof
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We combine a visual check of cracks with the thermal images around them.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
What a thermal roof survey does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- What’s inside walls or under coverings, without opening up
- Proving moisture from the images alone
- Structural calculations, which need a structural engineer
If in doubt, call 07833 053749 or drop us an email and we’ll suggest the right survey. What our survey covers.
What we look at
- Flat roofs
- Insulated roof spaces
- Ceilings below the roof
- Loft conversions
- Commercial roofs
- Pitched roof slopes
Drones, thermal imaging and Erith roofs
Hall Place and Gardens, about 2.3 miles south, is one of the historic houses in the wider area around Erith. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Erith is about 2 miles from the edge of the flight restriction zone around London City Airport. If the drone is used for your survey, the exact boundary is checked for the address first.
Take an older house close to Christ Church: thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Parking in Erith, as in most of London, takes a little planning: tell us about permits, visitor bays or off-street space when you book.
Erith is about 3 miles north-west of Dartford, in Greater London. Erith is part of the area we cover across London and South East England. Our area takes in places right across Greater London. London is in our area too.
Thermal roof surveys in DA8, DA17 and DA7 work the same way as everywhere else we cover. If you need a thermal roof survey at a property on Church Road, Town Square and Erith High Street or anywhere close by, we can survey it. If you are just outside Erith, we cover Northumberland Heath (1 mile south), Bexley Riverside (1 mile south), Belvedere (1 mile north-west), Lessness Heath (1 mile north-west) and Barnehurst (1 mile south). We also work in nearby towns like London (11 miles west), City of Westminster (14 miles west), Marylebone (14 miles west), St Pancras (13 miles west), Shoreditch (11 miles west) and Walthamstow (11 miles north-west).
