Thermal imaging roof survey in Crawley, Oxfordshire
Thermal imaging to find moisture and heat loss patterns in a roof for Crawley, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Cold areas below the roof
- Leaks far from where the stain appears
- Areas losing heat at the eaves and junctions
Thermal roof survey in Crawley
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. If you’re worried about heat escaping through the roof and damp that repairs haven’t cured, we can find out what’s behind it, whatever the roof.
In a village or hamlet like Crawley, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Both the forecast and the airspace are checked first. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Flying and imaging in Crawley
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. Older buildings in west Oxfordshire frequently have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
Take an older house close to Church of St John the Evangelist: steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view by drone or thermal camera helps. Minster Lovell Hall, about 1.1 miles west, is one of the historic houses in the wider area around Crawley. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager does not touch the roof itself.
Crawley is about 1 mile north-west of Witney, in Oxfordshire. We provide thermal roof surveys for homes and businesses in Crawley. Crawley is one of the places in Oxfordshire we cover for thermal roof surveys. There’s also a page for Oxford.

Questions from Crawley
Do you carry out roof surveys in Crawley?
Yes, Crawley is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Do you cover smaller places like Crawley?
Yes, Crawley is on our map. Villages and rural addresses get the same survey as a town house.
What’s in the report?
You get our findings in writing, part by part, with photos. The most urgent items are made clear.
What’s the best way to book?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How many surveys have you done?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Roof by roof
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. Our report notes how the conditions affected the images.
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. The camera can help show damp around these junctions.
How the survey works
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. A typical survey takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a hamlet or village like Crawley, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We check the roof from the ground, from windows and from the roof itself where it’s safe.
- 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.
Before the survey
- If it isn’t your property yet, arrange access through the agent
- For flats, make sure roof access has been agreed
- Have any questions written down, so nothing gets missed
Booking a survey
Most bookings start with a short call: call 07833 053749 or email us and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
Advice
Also in Crawley
Tips that help
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Keep outlets and gutters clear to stop water sitting
- Check the loft can be reached safely
- Talk to us about the weather when booking
- Check from the ground or a window, never by climbing
Where a pattern cannot be confirmed, the report says what could help, like electronic leak detection or opening up a small area.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
For landlords and managing agents
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which helps when tenants work during the week.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant, which helps with budgets and planning.
When you need someone else
Before booking, it is worth knowing what a survey will not do:
- A formal energy assessment
- What’s inside walls or under coverings, without opening up
- Clear results when the conditions on the day are poor
If you are not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer before you book. The full list of what we check.

Signs you need a thermal roof survey in Crawley
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. The camera helps narrow the search.
Here are some of the things we see often:
- Thin or uneven insulation in the roof
- Cold areas below the roof
- Leaks that are hard to trace
- Moisture around outlets and upstands
If you look after a building like Hailey Church of England Primary School, thermal images can show where wet insulation sits under a big flat roof.
Before booking anyone
- Whether any drone flown is registered with the CAA
- What they will not be able to tell you
- Which viewpoints they use to see the roof
- What experience they bring
