Southall Thermal Roof Survey
Thermal roof surveys in Southall, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.
- Gaps in loft insulation
- Possible trapped moisture under a flat roof covering
- Stains that keep coming back
How a thermal roof survey works in Southall
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera does not see water itself, so we check what it shows with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We survey pitched roof slopes, insulated roof spaces and loft conversions, and common reasons people get in touch are wet areas near outlets and upstands and missing or slipped insulation.
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. Weather on the day decides whether it goes ahead, in Southall as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What a thermal roof survey doesn’t cover
We only report what can be seen safely on the day, so some things are outside what a survey can do:
- Insulation values or heat loss calculations
- Clear results when the conditions on the day are poor
- Hidden layers that need to be opened up to check
If you’re not sure which survey you need, call 07833 053749 or email us and we’ll give you a straight answer before booking. What our survey covers.
Roof types and parts we check
- Loft conversions
- Insulated roof spaces
- Commercial roofs
- Flat roofs
- Ceilings below the roof
- Pitched roof slopes
Surveys for landlords and agents in Southall
Landlords, agents and building managers in Southall and across Greater London can book any of our surveys. To discuss a property or a block, call 07833 053749 or email us.
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.

Prices for thermal roof surveys in Southall
Prices always include VAT. What changes the price is:
- How tall the building is and how easy the roof is to see
- The roof’s overall size
- Any need for thermal images or a drone flight
- Whether you choose the Basic, Standard or Premium Survey
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £400, including VAT.
Helping us price your survey
These details help when you get in touch:

What a thermal roof survey looks like in Southall
The wider area around Southall has a long history of building, with Osterley House about 1.7 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often 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. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
Take a building like Hambrough Primary School: big roofs are where aerial photos and thermal images show the most at once. For an older house near a landmark such as Saint John, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from above or with a thermal imager helps.
Southall is about 3 miles west of Ealing, in Greater London. Bookings from Southall are handled just like any other: a call or an email, a price, then a date. Southall is one of the places in Greater London where we work. There is also a page for London.
We work across the UB2, UB1, UB6 and W7 postcode area for thermal roof surveys and the streets around it. You’ll find streets such as Uxbridge Road High Street, Emerald Square and Randolph Road. If you are just outside Southall, we cover Dormers Wells (1 mile north-east), West Ealing (2 miles east), Yeading (2 miles north), Yiewsley (2 miles north) and Hanwell (2 miles east). Within a short drive, we also cover London (12 miles east), City of Westminster (10 miles east), Marylebone (10 miles east), Kensington (8 miles east), St Pancras (11 miles east) and Shoreditch (13 miles east).

Common questions in Southall
Does a conservation area affect roof work in Southall?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s 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.
Is drone flying allowed in Southall?
Normally it comes down to two things: the airspace at the address and the weather. The flight restriction zone around Heathrow Airport comes within about 2 miles of Southall. 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. Every London address is checked against them before a flight. High wind or heavy rain also stops a small drone flying, though the rest of the survey goes ahead either way.
Will you photograph what you find?
Yes. We photograph the roof as we go, and they go into the written report.
Are you insured?
We hold professional indemnity and public liability insurance.
Will the camera show exactly where the water is?
The camera does not see water itself. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
How do I arrange a thermal roof survey in Southall?
To arrange a survey, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
What we do, step by step
The visit has one job: to look at the roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit usually takes about one to two hours on an ordinary house; commercial roofs usually need 3–4 hours. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- You tell us about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- Make a note of anything you’d like us to look at
- Show us where any leaks or stains appear
- Keep pets inside or away from the areas we are looking at

Do you need a thermal roof survey in Southall?
Some defects simply cannot be seen with the eye. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. A thermal camera adds another way of finding them.
Here are some of the things we see frequently:
- Cold spots on ceilings under the roof
- Water that travels before it shows
- Thin or uneven insulation in the roof
- Moisture around outlets and upstands
For businesses in and around places such as Treaty Centre, thermal images can show trapped moisture across a wide commercial roof.
What to check before booking
- What insurance they carry
- Whether VAT is in the quoted price
- What’s outside the scope of the survey
- Which viewpoints they use to see the roof
