Thermal imaging roof survey in Crawley, Hampshire
Find out what’s going on with the roof before you decide what to do next. We carry out thermal roof surveys in Crawley.

- Water getting in at parapets and stacks
Landlords, agents and block managers in Crawley
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we will plan the visit with that in mind.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant ahead of time.
Thermal roof survey in Crawley
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. 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 insulated roof spaces, loft conversions and pitched roof slopes, and common reasons people get in touch are damp where roofs meet walls and chimneys and ceilings that feel colder in places.
Some older homes in villages like Crawley are listed or in a conservation area. A look by drone or thermal camera doesn’t touch the roof, which suits a building where any change needs care. Check with the council before planning any work on a listed building or one in a conservation area.
After the visit, you get a report with photos, sent by email. It sets out the condition of the roof, any defects and our written recommendations.

Why it is worth a survey now in Crawley
If a big flat roof may need replacing, knowing the wet areas first is useful. Thermal imaging, checked with moisture readings, gives a clearer picture before you commit. For an older or listed building in a place like Crawley, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, with VAT included. We will tell you which package suits the questions you have.

What we do, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a hamlet or village like Crawley, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- 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.
Before the survey
- Note where any stains or damp appear
- Leave side gates unlocked
- Mention any parking restrictions on your street
Booking a survey
Our price is from £400, including VAT. The exact figure depends on the roof and the package, so call 07833 053749 or send us an email with the details.

Should I look at the roof myself first?
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Drones, thermal imaging and Crawley roofs
A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your 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, so the council is the place to ask.
If yours is one of the older homes in the streets near Church of St Mary, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help. In and around Crawley, as anywhere, a roof is easiest to deal with when its problems are found early.

FAQs for Crawley
Does a conservation area affect roof work in Crawley?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you cover Crawley?
Yes, Crawley is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property.
What does a thermal roof survey show?
The camera records how the surface temperature varies. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
Can you inspect my roof with a drone?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Are you insured?
Our cover is professional indemnity plus public liability, and details are available on request.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
Useful tips for Crawley property owners
A little preparation and a few simple habits help. Some pointers:
- Keep the heating on as usual before a heat loss survey
- Keep outlets and gutters clear to stop water sitting
- Note where damp appears and after what weather
- Talk to us about the weather when booking
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
