Heathrow Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof across Heathrow, with drones and thermal imaging where they help. Get in touch for a price.
- Leaks that are hard to trace
- Damp where roofs meet walls and chimneys
- Wet insulation beneath the membrane
Why it is worth a survey now in Heathrow
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. Older cottages and farmhouses around Heathrow can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.

Thermal roof surveys for homes and businesses in Heathrow
Thermal imaging is useful when a damp patch has no clear cause. Leaks often run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. We combine the images with a visual inspection and moisture readings, so the findings don’t rely on the camera alone. If you’ve noticed thin or uneven insulation in the roof and water getting in at parapets and stacks, we can find out what’s behind it.
Older buildings in small places like Heathrow may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

Rented homes, blocks and businesses
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or email us.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Flying and imaging in Heathrow
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. The flight restriction zone around Heathrow Airport covers Heathrow, or comes right up to its edge. If the drone is used for your survey, permission from the airport is needed first, and the flight only goes ahead if it’s given.
If you run a hotel or guest house in or near Heathrow, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition. For businesses in and around places like Treaty Centre, large commercial roofs are often easiest to see from above or with a thermal imager. Historic houses such as Osterley House, about 4.6 miles east, show how far back building around Heathrow goes. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings.
Heathrow is about 2 miles north-west of Feltham, in Surrey. Heathrow gets the same service as everywhere else we work: a careful inspection, photographs and a written report. We cover towns and villages across Surrey. You can also see our page for London.
We survey roofs across the TW6 postcode area for thermal roof surveys. Other places close to Heathrow include West Bedfont (1 mile south-west), Hatton (1 mile east), Bedfont (1 mile south-east), Stanwell (1 mile south-west) and Harlington (1 mile north-east). We also work in nearby towns such as Woking (12 miles south-west), Camberley (15 miles south-west), Epsom (12 miles south-east), Ewell (12 miles south-east), Egham (5 miles south-west) and Walton-on-Thames (6 miles south).
Around Heathrow
In Heathrow, that means homes and buildings near The Queen's Arms and Space Studio West London and the streets around them. There is a railway station in Heathrow itself: Heathrow Terminals 2 & 3 Rail station. Other landmarks nearby include Spelthorne Museum (3.5 miles south-west) and Harlington (1.6 miles north). Open spaces near Heathrow include Staines Reservoirs and Crane Meadows.
What we do, step by step
Once we’ve finished looking, we write up our findings in a report with photographs, emailed to you. As for time on site, it normally takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older roofs in small places like Heathrow can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- Mention any parking restrictions on your street
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work

Honest limits
No survey can tell you everything, and it’s better to know them up front. Keep these in mind:
- Insulation values or heat loss calculations
- Whether the deck or roof structure is strong enough
- What’s inside walls or under coverings, without opening up

What this survey covers
- Loft conversions
- Insulated roof spaces
- Ceilings below the roof
- Flat roofs
- Pitched roof slopes
- Commercial roofs
Roof by roof
Parapets, valleys and junctions
Problems where roof slopes and walls meet are often hidden. A careful visual inspection goes alongside the images.
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. Thermal images can show where it has been pushed aside.
Practical tips
Nothing here needs a ladder. A few suggestions:
- Don’t climb onto the roof to look for leaks yourself
- Note where damp appears and after what weather
- Keep outlets and gutters clear to stop water sitting
- Keep dated photos of any marks on ceilings
If you are buying, the report gives you specific points to raise with the seller or agent. It is your decision how to use it, whether that is asking for work or discussing the price.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. Less standing water means less chance of it getting under the covering.
FAQs for Heathrow
Is my home in Heathrow listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you fly a drone over a roof in Heathrow?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around Heathrow Airport covers Heathrow, or comes right up to its edge. Before any flight there, we ask the airport for permission, and the flight only goes ahead if it is given. A small drone cannot fly safely in high wind or heavy rain.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Can you use a thermal camera on a sloping roof?
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 combine it with an inspection from the loft where there’s safe access.
How much does a thermal roof survey cost?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where applicable, structural analysis and a report on the same day.
Is Heathrow in your area?
Yes. We survey roofs across London and South East England, Heathrow included.
Can you check my loft insulation with a thermal camera?
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.
