How a thermal roof survey works in Chiswick
Your report sets out the thermal images alongside ordinary photos, so it is 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. You can talk the findings through with us at the in-person consultation. There is a 12-month follow-up as well. We’re often asked to look into water getting in at parapets and stacks and stains that keep coming back, across insulated roof spaces, flat roofs and loft conversions.
Flying in London takes more checking than most places: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every address in Chiswick is checked before any drone flight, and where permission is needed, the flight waits for it.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What we do, step by step
The aim of the visit is simple: 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 normally takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there is safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Preparing for the visit
- Make sure the loft hatch can be reached
- Make sure we can get to the back of the property
- Let us know about parking before the day
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or send us an email when you’re ready.

Tips from our surveys
You do not need to be a roofer to help. Here’s what helps most:
- Ask us about the forecast if rain is expected
- Check outlets after heavy rain
- Heat the home normally on the days before
- File the images with your roof records
Where a pattern cannot be confirmed, the report says what could help, for instance electronic leak detection or a roofer opening up a small section.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
What a thermal roof survey looks like in Chiswick
The flight restriction zone around London Heliport in Battersea comes within about 2 miles of Chiswick. If your survey includes the drone, we check the exact boundary for the address before flying. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in 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.
If you run a hotel or guest house in or near Chiswick, a roof problem can mean rooms out of use, so it pays to find faults before guests do. Chiswick is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
Chiswick is about 1 mile south of Acton, in Greater London.

Questions from Chiswick
How do I find out if my home in Chiswick is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Will parking be an issue for a roof survey in Chiswick?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we will agree the details as you book.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the report shows where to look more closely.
Do you work in Chiswick?
Yes. We cover Chiswick and the rest of Greater London. For a price, phone 07833 053749 or drop us an email.
How long have you been surveying roofs?
We have completed more than 5,000 surveys, over more than 20 years, with 98% customer satisfaction.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Let us know about it when you book and we’ll explain what’s needed.
What affects the price in Chiswick
Prices vary from roof to roof, and it comes down to:
- Basic, Standard or Premium
- House, block, shop or office
- How many separate roofs there are, such as extensions, dormers and garages
- Any need for thermal images or a drone flight
Prices quoted always include VAT, and the written report is part of the package. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.
What we need to know
A few details help us recommend the right survey and price. When you get in touch, it is useful to mention:
- Your timetable, such as an exchange date
- Any photos you have, taken from the ground or a window
- The reason for the survey, like buying, a leak or storm damage
- Any marks or damp showing indoors
Getting a price is simple: just ring 07833 053749 or drop us an email, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
What we cannot see
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- Readings unaffected by sun, shade or reflections
- What’s inside walls or under coverings, without opening up
- An energy rating for the building
If you are not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer. What our survey covers.
What we look at
- Ceilings below the roof
- Insulated roof spaces
- Loft conversions
- Pitched roof slopes
- Commercial roofs
- Flat roofs
Signs you need a thermal roof survey in Chiswick
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. Temperature patterns can help narrow down where to look.
People normally book a survey when they’ve noticed one of these:
- Wet areas near outlets and upstands
- Areas losing heat at the eaves and junctions
- Cold spots on ceilings under the roof
- Damp patches with no obvious cause
If your house is among the older ones in the streets near St. Nicholas Church, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Questions to ask before you book
- Whether the roof space is looked at, where there is one
- Their drone registration, if they fly one
- Whether VAT is in the quoted price
- Their insurance cover
Different roofs, different checks
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there’s safe access.
