About our thermal roof survey in Hadley Wood
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’s why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they do not. If a finding cannot be confirmed, the report suggests a next step. We survey pitched roof slopes, insulated roof spaces and commercial roofs, and the problems we are asked to look at most are stains that keep coming back and wet insulation beneath the membrane.
Many London roofs are hidden from the pavement: 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 Hadley Wood as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
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.

Checking the roof from the ground
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
What affects the price in Hadley Wood
Survey packages start from £150, with VAT included. The price for your roof depends on:

GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there’s a pattern around them.
Loft insulation
The difference is clearest when the home is heated and it’s cold out. Our report notes how the conditions affected the images.
Common questions in Hadley Wood
Can you fly a drone over a roof in Hadley Wood?
The answer turns on the exact location and the conditions 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. Every London address is checked against them before a flight. Before any flight, we check the Drone Safety Map for airspace restrictions. Strong wind or heavy rain also stops a small drone flying.
Is parking a problem for a survey in Hadley Wood?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
What does the report include?
A report with photographs, explaining the condition of the roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
How does a thermal imaging roof survey work?
The camera records how the surface temperature varies. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
How long is the visit?
Most surveys take roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. The report follows by email.
How quickly is the report sent?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Flying and imaging in Hadley Wood
About 2.6 miles north lies Wyllyotts Manor, a reminder of how long the area around Hadley Wood has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Steep or complicated roofs are frequently hard to see from ground level, which is where close-up aerial shots and thermal images help.
Controlled parking zones are common in London, so mention any permit rules for Hadley Wood. Anyone responsible for a site like Livingstone Primary and Nursery School will know that thermal images can show where wet insulation sits under a big flat roof. Shop and office owners around Spires Shopping Centre may find that big, flat commercial roofs are where aerial photos and thermal images help most.

Tips from our surveys
Over many surveys, some simple habits stand out:
- Keep the heating on as usual before a heat loss survey
- Clear a path to the loft hatch before we arrive
- Take photos of stains as they appear, so we can compare
- Ask us about the forecast if rain is expected
If you’re buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether you ask for work before completion or discuss the price.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is frequently moved when people work in the loft space.
How the survey works
It helps 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. Most visits take about one to two 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, let us know when you book.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Before we arrive
- Make sure we can get to the back of the property
- Note where any stains or damp appear
- Make sure pets are kept safely away
