About our thermal roof survey in Heston
We present each thermal image next to a normal photo of the same area, so it’s easy to see which part of the roof each one shows. We explain what each pattern may mean, what the moisture readings found and what we recommend. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. A follow-up 12 months later is included too. Typical surveys look at areas of a flat roof that may hold water and wet areas near outlets and upstands, across flat roofs, pitched roof slopes and commercial roofs.
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. The weather decides the day: both drones and thermal cameras need the right conditions. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later.

Drones, thermal imaging and Heston roofs
Within a mile and a half or so of Heston there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, large roofs are where close-up aerial shots and thermal images show the most at once. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Heston is one of them, bay roofs, hips and later dormers each have their own details. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
With Osterley House about 1.2 miles east, the area around Heston has a long history. Older roofs nearby can be steep and hard to see from the ground, and a survey from above or with a thermal imager does not touch the roof itself. If you look after a building such as Westbrook Primary School, big roofs are where close-up aerial shots and thermal images show the most at once.
Heston is about 2 miles south of Southall, in Greater London. We survey roofs in Heston and the rest of Greater London. Heston is one of the places in Greater London we cover. We also survey roofs in London.
We survey roofs across TW5, UB2 and TW3 for thermal roof surveys and the streets around it. Streets in the area include Fern Lane, Sutton Road and Eton Avenue, and we cover them all. Main roads around Heston include the A3005, which makes travel easy. If you’re just outside Heston, we cover North Hyde (1 mile north), Norwood Green (1 mile north-east), Lampton (1 mile south-east), Hounslow West (1 mile south) and Osterley (1 mile east). Further out, we also cover London (12 miles east), City of Westminster (10 miles east), Marylebone (10 miles east), Kensington (8 miles east), St Pancras (12 miles east) and Shoreditch (13 miles east).

The nearest railway station is Southall station, about 1.4 miles north. Other landmarks nearby include Museum of Army Music (2.4 miles south-east) and Treaty Centre (1.3 miles south-east). Open spaces near Heston include Northala Fields and Crane Meadows.
Why act early in Heston
If a big flat roof may need replacing, knowing the wet areas first is useful. Images backed by moisture readings show where problems seem to be before you commit. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Why book with us
- Plain-English reports with photos
- An independent view of the roof
- Package prices that include VAT

What happens on the day
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes about one to two hours on an ordinary house; commercial roofs usually need 3–4 hours. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Heston moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- 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 is 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.
Getting ready for the survey
- Check we can get to the back of the property
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches
Getting a price
We survey roofs on weekdays, Saturdays and Sundays. To arrange a day that suits you, phone 07833 053749 or email us with the address and the days you’d prefer.
Advice
When to book a survey in Heston
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
Problems we come across often include:
- Cold areas below the roof
- Heat escaping through the roof
- Damp where roofs meet walls and chimneys
- Thin or uneven insulation in the roof
For businesses in and around places like Treaty Centre, thermal images can show trapped moisture across a wide commercial roof.
Before you book anyone
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether VAT is in the quoted price
- Whether any drone flown is registered with the CAA
- Whether the roof space is looked at, where there is one
What a thermal roof survey doesn’t cover
Some things cannot be seen without opening up the roof, so a survey has limits:
- An energy rating for the building
- Confirming water without moisture readings
- Structural calculations, which need a structural engineer
If in doubt, ring 07833 053749 or drop us an email and we will recommend the right survey before booking. The full list of what we check.

Your questions about thermal roof surveys in Heston
Can you fly a drone over a roof in Heston?
The answer turns on the exact location and the conditions on the day. Heston is about 1 mile from the edge of the flight restriction zone around Heathrow Airport. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. 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. A small drone cannot fly safely in strong wind or a downpour.
Can parking be tricky for a visit in Heston?
Typically it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
What insurance do you have?
Our cover is professional indemnity plus public liability.
What does a thermal roof survey show?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Let us know which days suit you when you book.
Does thermal imaging work on slate and tile roofs?
It can help, but the results are frequently less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we also look from the loft where it’s safe.
Will the survey show heat loss through my roof?
The camera can point to heat loss and gaps in insulation. The survey is not an energy rating or a heat loss calculation, but the report shows where to look more closely.
Tips from our surveys
There’s plenty you can do without going near the roof. Here’s what helps most:
- Heat the home normally on the days before
- Keep a record of when stains appear
- Clear a path to the loft hatch before we arrive
- Photograph damp patches with the date
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, with our recommendations. Premium reports are sent the same day.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
