About our thermal roof survey in Fern
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. Moisture readings are then used to check what the camera suggests. We survey loft conversions, commercial roofs and ceilings below the roof, and common reasons people get in touch are cold spots on ceilings under the roof and water getting in at parapets and stacks.
In a village or hamlet like Fern, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what can’t be reached safely. Both the forecast and the airspace are checked first. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The report records the roof as we found it on the day. It is useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

Fern questions
Will you come out to Fern?
Yes, Fern is covered. We work right across London and the South East, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Is my home in Fern listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will you walk on the roof?
Only if it’s safe. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. Anything we cannot see is noted in the report.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Can a thermal camera see water?
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.
When to book a survey in Fern
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.
Signs worth acting on include:
- Thin or uneven insulation in the roof
- Moisture around outlets and upstands
- Cold areas below the roof
- Damp patches with no obvious cause
If you look after a shop, office or commercial unit, for example near Eden, large commercial roofs are often easiest to see from the air or with a thermal camera.
What to check before booking
- Is VAT included in the price?
- Whether the inside of the roof is included
- How they plan to inspect the roof safely
- Is there a chance to talk the report through?
DIY checks: what’s safe
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Different roofs, different checks
Loft insulation
In the loft space, the camera can pick up gaps and thin areas of insulation. We look where there is safe access.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and cannot be read from them.
Thermal roof surveys around Fern
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. About 2.7 miles south-east lies Cliveden, a reminder of how long the area around Fern has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to Church of St John the Baptist: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from above or with a thermal imager helps. Anyone responsible for a site like Little Marlow CofE School will know that a view from above covers a wide roof far faster than walking it.
Fern is about 2 miles north-east of Marlow, in Buckinghamshire. Houses, flats, blocks and commercial buildings in Fern can all book thermal roof surveys, with a written report and photographs every time. Our area takes in places right across Buckinghamshire, from the larger towns to small villages. For surveys nearby, see our Reading page.
Thermal roof surveys in SL7 work the same way as everywhere else we cover. We also cover the places around Fern: Coldmoorholme (1 mile south-east), Little Marlow (1 mile south-west), Well End (1 mile south-east), Bourne End (1 mile south-east) and Flackwell Heath (1 mile north-east). Within a short drive, we also cover High Wycombe (3 miles north), Chesham (10 miles north-east), Amersham (8 miles north-east), Beaconsfield (4 miles east), Chalfont St Peter (8 miles east) and Southcourt (15 miles north).
Around Fern
In Fern, that means homes and buildings near Bourne End Academy and The Black Lion pub and the streets around them. The closest station to Fern is Bourne End station, roughly 1.1 miles south-east. Well-known places in the area include High Wycombe Castle (3.1 miles north) and Chiltern Sound Phonograph Museum (2.3 miles south-west). For a walk, there is Warren Nature Reserve.
What happens on the day
We work from the outside in: outside views come first, then the loft space if there’s safe access. All told, expect about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Somewhere like Fern needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can be seen safely, inside and out.
- 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.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- Clear the way to the loft hatch
- For a flat or shared roof, check access with the freeholder or managing agent
- Find any records of previous roof work

Advice

Why act early in Fern
Wet insulation under a flat roof does not dry out on its own while the covering stays on. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. Around Fern, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 with VAT included. We can help you choose the package that fits what you’d like to know.
Why book with us
