Thermal roof survey in Dorking: what you get
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. We survey loft conversions, insulated roof spaces and commercial roofs, and common reasons people get in touch are cold spots on ceilings under the roof and stains that keep coming back.
Before any drone flight in a town like Dorking, the airspace is checked on the Drone Safety Map, including zones around airports and prisons. We fly a sub-250g drone and hold a CAA Flyer ID and Operator ID. Neighbours’ privacy is part of planning every flight. Flights stay below 120 m (400 ft) and within sight, as the open category requires.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Why act early in Dorking
Heat lost through a roof costs money every winter. Thermal images can show where insulation is missing or has slipped, so you know where to put things right. In a family home in Dorking, a small roof fault lets water into places you cannot see, soaking loft insulation, wall tops and timbers. By the time a stain appears on a ceiling, there’s more to put right.
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we will tell you which fits.

Take a look at what a roof survey costs and what we found on two real jobs.
What a thermal roof survey looks like in Dorking
Dorking has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, large roofs are where aerial photos and thermal images show the most at once. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
With Polesden Lacey about 2.7 miles north-west, the area around Dorking has a long history. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. Hotels and guest houses near Dorking cannot easily close rooms for a leak, so it is worth knowing the roof’s condition. Take an older house close to Church of St Paul: older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Dorking is about 10 miles north-west of Crawley, in Surrey. We visit Dorking as part of our work across Surrey. Across Surrey, we cover Dorking. You can also see our page for Crawley.

What we look for on each type of roof
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. We check any patterns with moisture readings.
Useful tips for Dorking property owners
From years of surveys, a few habits stand out as worth the effort:
- Ask us about the forecast if rain is expected
- Clear a path to the loft hatch before we arrive
- Heat the home normally on the days before
- Tell us where and when you’ve seen damp or stains
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’s asking for work or discussing the price.
Check loft insulation covers the whole area and hasn’t been disturbed. Gaps often appear after work in the loft.
Dorking: your questions answered
Does a conservation area affect roof work in Dorking?
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. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
What do I need to do before a survey in Dorking?
Clear the way to the loft hatch if there is one, and tell us about any leaks, stains or past repairs. Parking and access details for Dorking help us plan the visit.
Can a thermal camera see water?
The camera does not see water itself. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
Do I need to be at home?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when you book.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Checking the roof from the ground
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

Honest limits
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Whether the deck or roof structure is strong enough
- A formal energy assessment
- What’s inside walls or under coverings, without opening up

- Insulated roof spaces
- Ceilings below the roof
- Flat roofs
- Commercial roofs
- Pitched roof slopes
- Loft conversions
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. A typical visit in Dorking begins with the street side of the roof and then moves round the building. The back garden is often where extensions, dormers and rear slopes are best seen, so unlocked gates help. The loft comes next, where there is safe access.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- 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
- Keep pets inside or away from the areas we are looking at
- For flats, make sure roof access has been agreed
- Leave a clear route to the loft
