Bletchingley Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof across Bletchingley, with drones and thermal imaging where they help. Get in touch for a price.
- Leaks that are hard to trace
- Water getting in at parapets and stacks
- Possible trapped moisture under a flat roof covering
Leave it or get it looked at?
Repeated repairs that do not stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, rather than more guesswork. Older cottages and farmhouses around Bletchingley can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
Why book with us
- An independent view of the roof
- More than 20 years surveying roofs
- Drones and thermal imaging where it applies
- We hold a CAA Flyer ID and Operator ID

How a thermal roof survey works in Bletchingley
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. 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. A follow-up 12 months later is included too. If you’ve noticed wet insulation beneath the membrane and heat escaping through the roof, we can find out what’s behind it, on insulated roof spaces, commercial roofs and flat roofs alike.
In a village or hamlet like Bletchingley, 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. Weather and airspace are looked at before the visit, and the journey is planned ahead of time. Steep slopes and tall chimney stacks are where a close-up view adds the most.
If any part of the roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Thermal roof surveys around Bletchingley
The flight restriction zone around Redhill Aerodrome comes within about 1 mile of Bletchingley. Where the drone is part of the survey, the exact boundary is checked for the address first. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
For businesses in and around places like The Belfry, thermal images can show trapped moisture across a wide commercial roof. For site and facilities teams at buildings such as Bletchingley Village Primary School, big roofs are where photos from the air and thermal images show the most at once.
Bletchingley is about 3 miles east of Redhill, in Surrey. We survey roofs in Bletchingley and the rest of Surrey, as part of our work across London and the South East. Bletchingley is one of the places in Surrey where we work for thermal roof surveys. There’s also a page for Crawley.

Practical tips
Over many surveys, some simple habits stand out:
- Heat the home normally on the days before
- Keep outlets and gutters clear to stop water sitting
- Keep the report to compare against after any repair
- Move stored items away from the loft hatch
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it’s easy to find each area on the roof.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
How it works
The visit typically starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. In total, it takes about 1–2 hours for most houses, or half a day or so for a commercial building. Older rural homes like those around Bletchingley can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Leave side gates unlocked
- Have any paperwork from past roof work to hand

Related advice
Should I look at the roof myself first?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.

Other services in Bletchingley
Do you need a thermal roof survey in Bletchingley?
After a repair, some owners want to know whether the roof has dried out. A thermal survey with moisture readings can show whether wet areas remain when the conditions on the day are suitable.
These are some of the problems a survey can pick up:
- Possible trapped moisture under a flat roof covering
- Patches of heat loss across the roof
- Cold spots on ceilings under the roof
- Leaks that are hard to trace
Take an older house close to Church of St Mary the Virgin: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from the air or with a thermal camera helps.

Roof by roof
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
FAQs for Bletchingley
Is drone flying allowed in Bletchingley?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around Redhill Aerodrome comes within about 1 mile of Bletchingley. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. The flight also waits for calm, dry weather.
Do you cover smaller places like Bletchingley?
Yes, Bletchingley is covered. We survey roofs 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.
How quickly is the report sent?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us when you book.
What happens after the survey?
The report arrives by email, with photographs and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
Does thermal imaging detect leaks directly?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
