Thermal imaging roof survey in Cowley, Greater London
Thermal roof surveys in Cowley and the rest of Greater London. Surveys run seven days a week.

How a thermal roof survey works in Cowley
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where applicable, structural analysis and a report on the same day. There is an in-person consultation as well, plus a follow-up 12 months later. You can phone 07833 053749 or email us with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey insulated roof spaces, flat roofs and commercial roofs, and the problems we are asked to look at most are patches of heat loss across the roof and moisture around outlets and upstands.
London’s roofs are often hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That’s where a view from the air or a thermal camera helps, by showing what can’t be reached safely. Weather on the day decides whether it goes ahead, in Cowley as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
Where we can’t see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t.

Thermal roof surveys in Cowley: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place. About 2.9 miles north-east lies Ickenham Hall, a reminder of how long the area around Cowley has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
For a London address like Cowley, it helps to know about controlled parking before the day, along with any off-street space. If you own one of the older houses in the streets near Church of St Laurence, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Cowley is about 2 miles south-west of Hillingdon, in Greater London. Cowley gets the same service as everywhere else we work: a careful look at what can be seen safely, photos and a clear written report. Across Greater London, we cover Cowley. For surveys nearby, see our London page.
Surveys in UB8, UB7 and UB10 are booked the same way as anywhere else. If you need a thermal roof survey at a property on Iver Lane, High Road and The Avenue or anywhere close by, we can help. Close by, we survey roofs in Uxbridge (1 mile north), Yiewsley (1 mile south-east), Hillingdon (2 miles north-east), Thorney (2 miles south) and New Denham (2 miles north). Within a short drive, we also cover City of Westminster (14 miles east), Marylebone (14 miles east), Kensington (12 miles east), Hampstead (13 miles east), Ruislip (5 miles north-east) and Brompton (14 miles east).

What this survey can’t tell you
A survey is a proper look at the roof, but it can’t do everything. The main limits are:
- Clear results when the conditions on the day are poor
- Proving moisture from the images alone
- The condition of timbers we cannot see
If you are not sure which survey you need, call 07833 053749 or email us and we will give you a straight answer before you book. What a survey covers and doesn’t.
Roofs we survey in Cowley
- Pitched roof slopes
- Ceilings below the roof
- Insulated roof spaces
- Loft conversions
- Commercial roofs
- Flat roofs
When to book a survey in Cowley
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 it’s warm inside and cold outside.
Typical things we’re asked to look at include:
- Patches of heat loss across the roof
- Cold areas below the roof
- Water getting in at parapets and stacks
- Leaks far from where the stain appears
If you run a business near The Chimes, big, flat commercial roofs are where photos from the air and thermal images help most.
What to check before booking
- What they won’t be able to tell you
- Will they check the loft as well as the outside?
- How they plan to inspect the roof safely
- Whether VAT is in the quoted price
What happens on the day
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. For a visit in Cowley, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- For a flat or shared roof, check access with the building owner or managing agent
- Let us know about parking before the day
- Leave a clear route to the loft
Arrange a survey
Most bookings start with a short call: ring 07833 053749 or use the contact form and we will ask a few questions about the roof. The price is agreed before a date is set.

Useful tips for Cowley property owners
Here are a few things we’d tell any owner:
- Leave the roof to people with safe access
- Heat the home normally on the days before
- Ask us about the forecast if rain is expected
- Move stored items away from the loft hatch
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
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.
Roof by roof
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We back up what the camera shows with a look in the loft where we can.
FAQs for Cowley
Is my home in Cowley 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.
Will parking be an issue for a roof survey in Cowley?
It depends on the street. If Cowley has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does thermal imaging work on slate and tile roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and can’t tell you, and back them up with a visual inspection and moisture readings.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where it applies, structural analysis and a report on the same day.
Does the weather affect a thermal survey?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we discuss the forecast when booking.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
For landlords and managing agents
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or use the contact form.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we will plan the survey around it.
