Thermal roof survey in Potters Bar: what you get

A thermal survey isn’t a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That is why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. If a finding cannot be confirmed, the report suggests a next step. We are often asked to look into water that travels before it shows and cold spots on ceilings under the roof, on insulated roof spaces, flat roofs and ceilings below the roof.

For a town like Potters Bar, every drone flight starts with a check of the Drone Safety Map, which shows restriction zones around airports and prisons. We fly a sub-250g drone and hold a CAA Flyer ID and Operator ID. Neighbours’ privacy is part of planning every flight. In the open category, flights stay under 120 m (400 ft) with the drone in sight.

Where we can’t see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t.

Potters Bar questions

What do I need to do before a survey in Potters Bar?

Very little. Keep pets out of the way, leave side gates unlocked and have any old roof paperwork handy.

Is Potters Bar in the area you cover?

Yes. We survey roofs across London and South East England, and Potters Bar is part of that. Just ring 07833 053749 or use the contact form and let us know about the property.

Do you use drones?

Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.

How long does the survey take?

Expect it to take about one to two hours at a typical home, and about three to four hours for a commercial roof. The written report follows by email.

What does a thermal roof survey show?

It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.

Does thermal imaging work on slate and tile roofs?

On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.

Do you survey roofs on blocks of flats?

Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so we need permission from the building owner or managing agent. We can only inspect what we are given access to.

Why get it checked now?

The longer moisture sits in a roof, the more it can affect timbers and finishes below. Looking now, while the damage may still be limited, keeps more options open. Around Potters Bar, gutters that overflow soak the wall below. A slipped tile or worn flashing does the same higher up. Left alone, both only get worse.

Thermal imaging and drone inspection (where applicable) come with the Premium Survey, which starts from £400, with VAT included. We will tell you which package suits the questions you have.

Flying and imaging in Potters Bar

If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. With Wyllyotts Manor about 0.4 miles west, Potters Bar sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.

For site and facilities teams at buildings like Ladbrooke Junior Mixed and Infant School, thermal images can show where wet insulation sits under a big flat roof. If you look after a shop, office or commercial unit, for instance near Spires Shopping Centre, a commercial roof can be photographed from above without anyone walking on it. If you live in an older home near St. Mary's Church, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from the air or with a thermal camera helps.

Landlords, agents and block managers in Potters Bar

Landlords and letting agents in Potters Bar book surveys as well as homeowners. The report gives you a dated record of the roof, with photos, which helps you plan work between tenancies.

Different roofs, different checks

Loft insulation

The difference is clearest when the home is heated and it is cold out. We explain in the report how the conditions on the day affected what we saw.

Felt and asphalt flat roofs

On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.

What a thermal roof survey does not cover

No survey can tell you everything, and it’s better to know them up front. Bear these in mind:

  • Hidden layers that need to be opened up to check
  • An energy rating for the building
  • Readings unaffected by sun, shade or reflections

If you are not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer before booking. What a survey covers and does not.

What this survey covers

  • Loft conversions
  • Commercial roofs
  • Ceilings below the roof
  • Insulated roof spaces
  • Pitched roof slopes
  • Flat roofs

How it works

Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take about one to two hours for most homes, plus time to check any thermal findings with moisture readings. For a home in Potters Bar, the main things we need are a way into the loft, a route to the back garden and somewhere to park. If you will not be there yourself, let us know who will let us in.

  1. We go through the roof, the problem and the weather expected on the day.
  2. The roof is inspected visually from safe positions.
  3. We take thermal images of the roof and of the loft where we can reach it.
  4. Patterns that stand out are checked with moisture readings.
  5. Each image is set beside a normal photo and explained in the report.

How to prepare

  • Keep pets out of the way during the survey
  • Point out any leaks or damp patches
  • Agree roof access with the managing agent if it’s shared

Related advice

Should I look at the roof myself first?

After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.

A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
