Botany Bay Thermal Roof Survey
Thermal roof surveys across Botany Bay, with over 20 years’ experience behind it. Every survey ends with a written report and photos.
- Stains that keep coming back
- Areas losing heat at the eaves and junctions
- Leaks that are hard to trace
How it works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take about 1–2 hours at a typical home, though large, tall or awkward roofs take more time. London terraces rarely offer a view of the whole roof from one spot, so in Botany Bay we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- Note where any stains or damp appear
- If you’re buying, check with the agent that we can get in
- Check we can get to the back of the property
Booking a survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, call 07833 053749 or drop us an email.

Thermal roof survey in Botany Bay: what you get
On a flat roof, wet insulation holds heat longer than dry insulation. 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. Moisture readings are then used to check what the camera suggests. We survey ceilings below the roof, pitched roof slopes and insulated roof spaces, and the problems we’re asked to look at most are heat escaping through the roof and leaks that are hard to trace.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. We take care to focus on the roof we have been asked to look at. Mention access, height and anything unusual about the building when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
Where we can’t see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t.

Common questions in Botany Bay
Is drone flying allowed in Botany Bay?
It depends on the exact address and the weather on the day. 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, including zones around airports and prisons. The flight also waits for calm, dry weather, and the rest of the survey doesn’t depend on the drone.
Is parking a problem for a survey in Botany Bay?
Sometimes, yes. If Botany Bay has controlled parking where you are, a visitor permit is the easiest answer.
How many surveys have you done?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Is thermal imaging good for finding leaks?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings, as the camera alone can’t prove a leak.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where it applies, structural analysis and a report on the same day.
Will you go up on the roof?
Only when it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and the report notes anything we couldn’t see.
What we are asked to look at in Botany Bay
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Common reasons to book include:
- Water that travels before it shows
- Damp around roof outlets and upstands
- Patches of heat loss across the roof
- Water getting in at parapets and stacks
For a London address like Botany Bay, it helps to know about controlled parking before the day, along with any off-street space.

Thermal roof surveys in Botany Bay: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of 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 aerial photos and thermal images help. With Forty Hall about 2.5 miles east, Botany Bay sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
If you look after a shop, office or commercial unit, for instance near Spires Shopping Centre, thermal images can show trapped moisture across a wide commercial roof. For site and facilities teams at buildings such as St. John's Senior School, big roofs are where close-up aerial shots and thermal images show the most at once.
Botany Bay is about 3 miles south-east of Potters Bar, in Greater London. Botany Bay gets the same service as everywhere else we work: a careful inspection, photographs and a written report. Across Greater London, we cover Botany Bay and the places around it. London is in our area too.

How we price thermal roof surveys
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Whether you choose the Basic, Standard or Premium Survey
- The shape of the roof and its details
- The roof’s overall size
- Whether thermal imaging or a drone is needed
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
These details help when you contact us:
- The reason for the survey, such as buying, a leak or storm damage
- Anything about access we should know
- Photos of the roof, taken safely from ground level or a window
- The kind of building and roof involved
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us.
What happens if roof problems are left?
A damp patch that keeps coming back typically has a cause that hasn’t been found. Combining the camera with moisture readings can help find it, rather than more guesswork. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
Every price we give includes VAT. Thermal roof survey starts from £400, including VAT. You will know the price for your survey before booking.

Roof by roof
Parapets, valleys and junctions
Problems where roof slopes and walls meet are frequently hidden. A careful visual inspection goes alongside the images.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. Wet boards can show as temperature differences on the images.
