Thermal imaging roof survey in Horsted Keynes, West Sussex
Thermal roof surveys in Horsted Keynes from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and the South East.
- Thin or uneven insulation in the roof
- Damp that repairs haven’t cured
- Damp around roof outlets and upstands
What we do, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Cottages and farmhouses around Horsted Keynes often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- If you’re buying, check with the agent that we can get in
- Keep pets out of the way during the survey
- Find any records of previous roof work

About our thermal roof survey in Horsted Keynes
On a flat roof, wet insulation holds heat longer than dry insulation. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, something you cannot typically tell from the surface. Moisture readings are then used to check what the camera suggests. We’re often asked to look into water getting in at parapets and stacks and cold spots on ceilings under the roof, on ceilings below the roof, insulated roof spaces and loft conversions.
Some older homes in villages like Horsted Keynes are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it’s a gentle way to see the condition of an old roof. Check with the council before planning any work on a listed building or one in a conservation area.
The report works through the roof section by section, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

What affects the cost of thermal roof surveys
Several things affect the price of a survey:
- Extra roofs, like extensions, dormers or garages
- Roof area
- Features like valleys, chimneys, dormers and parapets
- Which survey package you book
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 including VAT. We will tell you which package suits the questions you have.
What we need to know
Here’s what helps us most when you contact us:
- Pictures of the roof from a safe spot, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- Whether there is a loft hatch, a shared roof or tricky access
- The type of building and roof, like pitched or flat
To book a survey, call 07833 053749 or email us with the address and what you’d like to know about the roof. You will know the price before anything is booked.
Different roofs, different checks
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. The camera can help show where to look.
Pitched slate and tile roofs
Inside the roof space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
What a thermal roof survey doesn’t cover
It is a careful look at the roof, not the whole story. Its limits include:
- A structural engineer’s assessment
- Confirming water without moisture readings
- Reliable images in rain, strong wind or on a wet roof surface
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer. The full list of what we check.
What we check
- Flat roofs
- Pitched roof slopes
- Loft conversions
- Commercial roofs
- Ceilings below the roof
- Insulated roof spaces
Checking the roof from ground level
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Flying and imaging in Horsted Keynes
Historic houses such as Priest House, about 3 miles north-west, show how far back building in the area around Horsted Keynes goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
For an older house near a landmark such as St Giles' Church, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

What we are asked to look at in Horsted Keynes
Some defects simply can’t be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Common reasons to book include:
- Cold spots on ceilings under the roof
- Damp patches with no obvious cause
- Damp where roofs meet walls and chimneys
- Wet areas near outlets and upstands
Take a building like St Giles CofE Primary School: a view from above covers a wide roof far faster than walking it.

Your questions about thermal roof surveys in Horsted Keynes
Do you carry out roof surveys in Horsted Keynes?
Yes. We survey roofs across London and South East England, and Horsted Keynes is part of that. Just call 07833 053749 or use the contact form and tell us about the property, and we’ll talk through which survey suits.
Is my home in Horsted Keynes listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is thermal imaging included in your surveys?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
Can a thermal survey trace a roof leak?
It frequently helps show where to look. Patterns can suggest where trapped water has spread. It is used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.
How quickly is the report sent?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
