Keymer Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof for Keymer, from an experienced roof surveyor. Every survey comes with a written report and photographs.
- Leaks that are hard to trace
- Heat escaping through the roof
- Moisture around outlets and upstands
Tips from our surveys
These tips come from what we see on roofs every week:
- File the images with your roof records
- Check outlets after heavy rain
- Keep the heating on as usual before a heat loss survey
- Let us know where and when you’ve seen damp or stains
Buyers can use the findings when talking to the seller or agent. What you do with it is up to you, whether that’s asking for work or discussing the price.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is frequently moved when people work in the loft space.
Thermal roof surveys for homes and businesses in Keymer
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where applicable, structural analysis and a report on the same day. An in-person consultation and a 12-month follow-up are included too. You can phone 07833 053749 or send us an email with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey flat roofs, insulated roof spaces and ceilings below the roof, and common reasons people get in touch are cold areas below the roof and gaps in loft insulation.
Older cottages and houses around Keymer may have little insulation, and some have extensions with their own roofs. A thermal image can show where heat is escaping or where moisture may be trapped, and drone photos show the roof surfaces themselves. Anything that looks like moisture is checked with a meter. Results depend on the weather, so the visit is planned around the forecast.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Airspace, weather and Keymer roofs
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Anyone responsible for a site like The Windmills Junior School will know that thermal images can show where wet insulation sits under a big flat roof.
Keymer is about 2 miles south of Burgess Hill, in West Sussex. We cover Keymer and the rest of West Sussex, as part of our work across London and South East England. Keymer is one of the places in West Sussex where we work. We also survey roofs in Brighton.
Here we cover the BN6 postcode area for thermal roof surveys. If you need a thermal roof survey at a property on Flowers Close, The Quadrant and Kymer Gardens or a nearby road, we can survey it. We also cover the places around Keymer: Hassocks (1 mile west), Ditchling (1 mile east), Clayton (1 mile south-west), Hurst Wickham (1 mile north-west) and Westmeston (2 miles south-east). Further out, we also cover Crawley (13 miles north), Horsham (13 miles north-west), Worthing (14 miles south-west), Haywards Heath (5 miles north), East Grinstead (15 miles north) and Shoreham-by-Sea (8 miles south-west).

Not far away are Ditchling Beacon and Bedelands Farm Nature Reserve.
When you need someone else
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Reliable images in rain, strong wind or on a wet roof surface
- Insulation values or heat loss calculations
- Hidden layers that need to be opened up to check
If you are not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer before booking. What our survey covers.
What we look at
- Flat roofs
- Ceilings below the roof
- Insulated roof spaces
- Commercial roofs
- Loft conversions
- Pitched roof slopes
Should I look at the roof myself first?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
What happens on the day
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. Some parts of a survey depend on the weather, so a visit to Keymer is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- Thermal images are taken to show differences in surface temperature.
- 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.
Preparing for the visit
- Find any records of previous roof work
- Agree roof access with the managing agent if it is shared
- Let us know where we can park nearby

Related advice
What else we do in Keymer
Different roofs, different checks
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We back up what the camera shows with a look in the loft where we can.
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. The camera can give clues to where it is sitting, when the conditions allow.
Keymer questions
Do you cover smaller places like Keymer?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Does a conservation area affect roof work in Keymer?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
Can you survey at the weekend?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Signs you need a thermal roof survey in Keymer
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
Most people get in touch when they’ve noticed one of these:
- Damp patches with no obvious cause
- Ceilings that feel colder in places
- Damp where roofs meet walls and chimneys
- Damp around roof outlets and upstands
The streets around a church such as St Cosmas and St Damian Church are frequently among the oldest in a place, and if your house is among the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from the air or with a thermal camera helps.
