Thermal roof survey in Pinner
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. We then check those areas with moisture readings. If you’re worried about cold spots on ceilings under the roof and possible trapped moisture under a flat roof covering, we can find out what’s behind it, whatever the roof.
London’s roofs are frequently hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That is where a view from the air or a thermal camera helps, by showing what cannot be reached safely. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put in order of urgency where relevant.

Airspace, weather and Pinner roofs
The wider area around Pinner has a long history of building, with Headstone Manor about 1.5 miles east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
For businesses in and around places like St. George's Shopping Centre, large commercial roofs are often easiest to see from above or with a thermal imager. If you live in an older home near Christian Science Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. Take a building like West Lodge Primary School: a view from above covers a wide roof far faster than walking it.

DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Check outlets after heavy rain
- Ask us about the forecast if rain is expected
- Take photos of stains as they appear, so we can compare
- Clear a path to the loft hatch before we arrive
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it’s easy to find each area on the roof.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Questions from Pinner
Can you fly a drone over a roof in Pinner?
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. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather.
Will parking be an issue for a roof survey in Pinner?
It can be, so it helps to let us know about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
Do you test for asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Does the report include photos?
Yes. We photograph the roof as we go, and they go into the written report.
What affects the cost of thermal roof surveys
We confirm the price for the job before booking. These are the things that affect it:
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- Height and safe access
- Any need for thermal images or a drone flight
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. You will know the price for the job before booking.
What to let us know when you contact us
These details help when you contact us:
- Why you want a survey: buying, a leak, a storm or new work

Honest limits
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Proving moisture from the images alone
- A structural engineer’s assessment
- Insulation values or heat loss calculations
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before you book. What our survey covers.

How the survey works
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, including by drone where it’s applicable and the weather allows. A typical visit takes between one and two hours at a typical home, while a commercial roof takes nearer three to four hours. In Pinner, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- 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.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Point out any leaks or damp patches
- Leave a clear route to the loft
