About our thermal roof survey in Southgate
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It isn’t an energy rating or a heat loss calculation. If you are worried about missing or slipped insulation and heat escaping through the roof, we can find out what’s behind it.
London’s roofs are frequently hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. Weather on the day decides whether it goes ahead, in Southgate as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. You’ll see the good as well as the bad.

Roof by roof
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences frequently show through. Any patterns are checked with moisture readings.
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Shiny surfaces can reflect heat, so we take care reading the images.
What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
What we do, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. Most surveys take an hour or two for most homes, plus time to check any thermal findings with moisture readings. London terraces rarely offer a view of the whole roof from one spot, so a visit in Southgate moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- 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.
How to prepare

FAQs for Southgate
Can you fly a drone over a roof in Southgate?
It depends on the exact address and the weather on the day. 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. Every flight is checked against the Drone Safety Map first. High wind or heavy rain also stops a small drone flying.
How do I find out if my home in Southgate is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Is thermal imaging included in your surveys?
Thermal imaging is included in our Premium Survey, from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
What happens after the survey?
You will get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Can thermal imaging show missing insulation?
Gaps and thin areas of insulation can show up on the camera. The difference is clearest when the building is heated and it is colder outside. We look from the loft as well, where there is safe access.
Airspace, weather and Southgate roofs
Bruce Castle, about 3.2 miles south-east, is one of the historic houses in the wider area around Southgate. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
Anyone responsible for a site like Ashmole Primary School will know that big roofs are where photos from the air and thermal images show the most at once. For a London address like Southgate, it helps to know about controlled parking before the day, along with any off-street space. Shop and office owners around Grand Arcade may find that a commercial roof can be photographed from above without anyone walking on it.

Why it’s worth a survey now in Southgate
Wet insulation under a flat roof does not dry out on its own while the covering stays on. Over time, it insulates less well and can harm the deck. Finding the wet areas sooner keeps the work smaller. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.
