Thermal roof surveys for homes and businesses in Lissenden Gardens
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you cannot usually tell from the surface. Moisture readings are then used to check what the camera suggests. If you are worried about missing or slipped insulation and cold areas below the roof, a survey will tell you what’s going on, whatever the roof.
Many London roofs are hidden from the pavement: butterfly roofs behind parapets, dormer tops and flat roofs over back 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 Lissenden Gardens as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

What we do, step by step
Once we have finished looking, we write up our findings in a report with photos, emailed to you. On timing, most surveys take roughly 1–2 hours for most houses, and more on a big or complicated roof. Surveys in Lissenden Gardens can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We look at the roof from ground level, from windows and from the roof itself where it is safe.
- We take thermal images of the roof to pick up temperature patterns.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photos and our recommendations.
Before the survey
- Clear the way to the loft hatch
- Have any questions written down, so nothing gets missed
- Unlock side gates and any roof access doors

Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
What a thermal roof survey looks like in Lissenden Gardens
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. With Keats House about 0.8 miles west, Lissenden Gardens sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
Lissenden Gardens is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when booking. For businesses in and around places such as O2 Centre, big, flat commercial roofs are where aerial photos and thermal images help most. If you look after a building like Parliament Hill School, thermal images can show where wet insulation sits under a big flat roof.

Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Check from the ground or a window, never by climbing
- Remember the conditions on the day affect the results
- Photograph damp patches with the date
- Make sure the loft can be reached safely
Premium Surveys include an in-person consultation, so you can go through the images with us. There’s a 12-month follow-up too.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
Honest limits
Before booking, it’s worth knowing what a survey won’t do:
- What’s inside walls or under coverings, without opening up
- Seeing water directly, as the camera shows temperature, not moisture
- Reliable images in rain, strong wind or on a wet roof surface
If you are not sure which survey you need, ring 07833 053749 or send us an email and we’ll give you a straight answer before booking. What a survey covers and doesn’t.

Common questions in Lissenden Gardens
How do I find out if my home in Lissenden Gardens is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Are there drone restrictions around Lissenden Gardens?
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. Every flight is checked against the Drone Safety Map first. A small drone can’t fly safely in high wind or heavy rain, though the rest of the survey goes ahead either way.
How do I arrange a thermal roof survey in Lissenden Gardens?
It’s easiest to call 07833 053749 or use the contact form. Tell us the address and a little about the roof. Surveys run on weekdays and at weekends.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to.
How long is the visit?
Most surveys take between one and two hours for a house, and longer for a large or complex roof. We will confirm the timing when you book.
