How a thermal roof survey works in Totteridge
A thermal camera can help when the cause of damp isn’t obvious. Water can travel some distance under a roof covering before it shows inside, and temperature patterns can help us trace where it may have come from. We combine the images with a visual inspection and moisture readings, so the findings do not rely on the camera alone. If you’ve noticed cold areas below the roof and water that travels before it shows, we can find out what’s behind it.
In London’s terraces and conversions, roofs are packed close together, 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.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Your questions about thermal roof surveys in Totteridge
Is parking a problem for a survey in Totteridge?
It rarely stops a survey, but it’s worth planning. Tell us what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Totteridge 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.
How long does the survey take?
Time on site depends on the roof, but most surveys take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. The report is sent afterwards by email.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Can you survey a shared roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Will the camera show exactly where the water is?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
The survey, step by step
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Leave side gates unlocked
- If the roof is shared, arrange access with whoever manages the building

Advice
When you need someone else
In fairness, a roof survey has limits:
- Reliable images in rain, strong wind or on a wet roof surface
- Seeing water directly, as the camera shows temperature, not moisture
- What’s inside walls or under coverings, without opening up
If in doubt, phone 07833 053749 or email us and we’ll recommend the right survey. The full list of what we check.

What else we do in Totteridge
Landlord and commercial surveys in Totteridge
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.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, ring 07833 053749 or drop us an email.
DIY checks: what’s safe
Look up at the roof after a storm, from the ground: 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.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Flying and imaging in Totteridge
Wyllyotts Manor, about 4.2 miles north, is one of the historic houses in the wider area around Totteridge. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
Totteridge is in London, so parking needs planning: let us know about parking bays, permits or a driveway as you book. For an older house near a landmark like St Andrew'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 Totteridge
After a repair, some owners want to know whether the roof has dried out. Thermal images and moisture readings can suggest whether moisture is still trapped when the conditions on the day are suitable.
Signs worth acting on include:
- Ceilings that feel colder in places
- Possible trapped moisture under a flat roof covering
- Wet areas near outlets and upstands
- Leaks far from where the stain appears
For businesses in and around places such as Spires Shopping Centre, thermal images can show trapped moisture across a wide commercial roof.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Will they check the loft as well as the outside?
- What follow-up you get after the report
- How long they’ve been surveying roofs
Roof by roof
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, when the conditions allow.
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.
