About our thermal roof survey in New Cross
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’re worried about damp patches with no obvious cause and thin or uneven insulation in the roof, we can find out what’s behind it, on pitched roof slopes, flat roofs and insulated roof spaces alike.
London roofs sit shoulder to shoulder in terraces and blocks, so privacy and neighbours matter as much as the view. We take care to focus on the roof we’ve been asked to look at. Tell us about the building and access as you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

How it works
On the day, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can safely be seen. The survey usually takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, tell us when booking.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Leave side gates unlocked
- Leave a clear route to the loft
- Mention any parking restrictions on your street

Rented homes, blocks and businesses
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.

Thermal roof surveys around New Cross
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
If you look after a shop, office or commercial unit, for instance near Lewisham Shopping Centre, thermal images can show trapped moisture across a wide commercial roof. For an older house near a landmark such as St James's Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

Signs you need a thermal roof survey in New Cross
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. A thermal survey, checked with moisture readings, can give a much clearer picture.
People typically book a survey after spotting something like this:
- Water getting in at parapets and stacks
- Areas losing heat at the eaves and junctions
- Damp patches with no obvious cause
- Cold areas below the roof
New Cross is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door cannot be promised.
Questions to ask before booking
- Whether you get a written report with photos
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Their drone registration, if they fly one
- Are they insured for the work?
Your questions about thermal roof surveys in New Cross
Is drone flying allowed in New Cross?
That depends on where the roof is and on the weather. Across London there are restriction zones around Heathrow, London City and London Heliport, plus 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. High wind or heavy rain also stops a small drone flying, though the rest of the survey goes ahead either way.
Will parking be an issue for a roof survey in New Cross?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.
Is thermal imaging good for finding leaks?
It can help narrow down where water may be getting in. Patterns can suggest where trapped water has spread. We combine it with a visual inspection and moisture readings, as the camera alone can’t prove a leak.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Can you use a thermal camera on a sloping roof?
It can help, but the results are often less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it is safe.
Is thermal imaging included in your surveys?
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.
Different roofs, different checks
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.
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. The camera can help show where to look.
Honest limits
In fairness, a roof survey has limits:
- Readings unaffected by sun, shade or reflections
- Proving moisture from the images alone
- Whether the deck or roof structure is strong enough
