Thermal roof survey in Farnham: what you get
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. If you’ve noticed missing or slipped insulation and damp patches with no obvious cause, we can find out what’s behind it, whatever the roof.
Before any drone flight in a town like Farnham, the airspace is checked on the Drone Safety Map, which shows restriction zones around airports and prisons. Our drone weighs under 250g, and we are a CAA-registered drone operator (Flyer ID and Operator ID). Neighbours’ privacy is part of planning every flight. In the open category, flights stay under 120 m (400 ft) with the drone in sight.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put in order of urgency where relevant.

Thermal roof surveys in Farnham: local notes
Within a mile and a half or so of Farnham there are several hotels, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, large roofs are where photos from the air and thermal images show the most at once. Farnham Castle, about 0.6 miles north-west, is one of the historic houses in the wider area around Farnham. 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.
Take a building like Farnham College: a view from above covers a wide roof far faster than walking it. Hotels and guest houses near Farnham can’t easily close rooms for a leak.
Farnham is about 6 miles south of Farnborough, in Surrey. Surveys in Farnham work the same way as everywhere we cover: a close look at whatever is safely visible, photographs and a clear written report. Farnham is one of the towns and villages in Surrey where we work for thermal roof surveys. We also survey roofs in Guildford.
We work across the GU9 and GU10 postcode area for thermal roof surveys. Whether your property is on Barncroft, Approach Road and Saxon Croft or a nearby road, we can help. Farnham is on the A31 and A287, so it’s easy for us to get to. Nearby, we also carry out thermal roof surveys in Compton (1 mile east), Hale (1 mile north), Upper Hale (2 miles north), Runfold (2 miles east) and Heath End (2 miles north). Further out, we also cover Guildford (10 miles east), Woking (12 miles north-east), Camberley (9 miles north), Frimley (8 miles north), Haslemere (9 miles south) and Cranleigh (14 miles east). Being one of Surrey’s larger places, Farnham has every kind of building, from houses and flats to offices.
Near you in Farnham
Locally, jobs take us to homes and businesses close to Moor Park, William Cobbett Public House and Weydon School and the streets around them. There is a railway station in Farnham itself: Farnham station. Well-known places in the area include Museum of Farnham (less than half a mile north-west) and Farnham Castle (0.6 miles north-west). The countryside around Farnham includes Farnham Park and Aunt's Pool.
What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
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.
Common roof problems in Farnham
Flat roofs that have leaked for a while can have wet insulation under the covering. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
Typical things we are asked to look at include:
- Damp that repairs haven’t cured
- Possible trapped moisture under a flat roof covering
- Cold spots on ceilings under the roof
- Damp around chimneys and parapets
If your house is among the older ones in the streets near St Joan of Arc's Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Before booking anyone

- Whether VAT is in the quoted price
The survey, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. After that, we look at everything we can see safely, from the ground, from windows, in the roof space and by drone where it applies. The survey typically takes an hour or two for most houses, rising to roughly 3–4 hours on a commercial building. Semi-detached and terraced homes in a town like Farnham frequently share a roof line with the neighbours, so we look at what can be seen of the shared parts from your side. It’s useful to know about previous repairs, leaks or recent work, so time on site goes where it is needed.
- 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.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Agree roof access with the managing agent if it is shared
- Leave side gates unlocked
- Make sure pets are kept safely away

Landlords, agents and block managers in Farnham
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
If the property is let, the agent or a tenant can let us in. We survey seven days a week, which helps when tenants work during the week.
How the survey changes by roof type
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We take that into account and check findings with moisture readings.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
What we cannot see
It helps to know what a survey will not do before you book:
- Hidden layers that need to be opened up to check
- Clear results when the conditions on the day are poor
- An energy rating for the building

Farnham: your questions answered
Is my home in Farnham listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
How should I get ready for a visit in Farnham?
Clear the way to the loft hatch if there is one, and let us know about any leaks, stains or past repairs. Parking and access details for Farnham help us plan the visit.
Is thermal imaging good for finding leaks?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source can’t be confirmed, we’ll say what could help next, such as electronic leak detection.
Do you test for asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
How do I arrange a thermal roof survey in Farnham?
Simply phone 07833 053749 or send us an email. We’ll ask a few questions, confirm the price and agree a date.
How long is the visit?
It usually takes between one and two hours for most houses, and longer for a large or complex roof. The report follows by email.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
