Northchapel Thermal Roof Survey
Know where you stand with the roof before you spend money on it. We carry out thermal roof surveys in Northchapel.
- Water getting in at parapets and stacks
- Water that travels before it shows
- Missing or slipped insulation
How a thermal roof survey works in Northchapel
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, something you can’t normally tell from the surface. We then check those areas with moisture readings. Typical surveys look at damp patches with no obvious cause and damp around chimneys and parapets, across pitched roof slopes, ceilings below the roof and loft conversions.
Somewhere as small as Northchapel, older roofs are frequently steep and partly hidden by trees or outbuildings. 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. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Questions from Northchapel
Does a conservation area affect roof work in Northchapel?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Northchapel?
Yes, Northchapel is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Can you inspect my roof with a drone?
Where it’s applicable and safe, yes. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It is included in the Drone Roof Survey and, where it applies, the Premium Survey.
What happens next?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you as you book.
Can you do a thermal survey in any weather?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
What insurance do you have?
Our cover is professional indemnity plus public liability.
What this survey can’t tell you
Every survey has limits, and it is better to know them up front. Keep these in mind:
- Hidden layers that need to be opened up to check
- Insulation values or heat loss calculations
- Readings unaffected by sun, shade or reflections
If you’re not sure which survey you need, call 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and does not.
Roofs we survey in Northchapel
- Insulated roof spaces
- Loft conversions
- Flat roofs
- Ceilings below the roof
- Commercial roofs
- Pitched roof slopes
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
Prices for thermal roof surveys in Northchapel
Prices always include VAT. What changes the price is:
- The number of roofs, including extensions and garages
- The roof’s overall size
- The type of building, from a house to a block or an office
- The height of the building and how the roof can safely be seen
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you need to know.
Getting in touch
Before you get in touch, it is useful to have:
- What made you get in touch
- The style of property, from a terrace to a block
- Where the property is, with the postcode
- Pictures of the roof from a safe spot, if you have them
To get a price for thermal roof surveys in Northchapel, ring 07833 053749 or drop us an email. The address, the type of property and what you want to find out help us give you an accurate price.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Keep the heating on as usual before a heat loss survey
- Clear leaves from outlets and gutters each autumn
- Photograph damp patches with the date
- Leave the roof to people with safe access
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
After repairs or a new covering, a later survey can confirm things are dry in suitable weather.
How it works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Around Northchapel, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Let us know about parking before the day
- Gather any invoices or paperwork from past roof work
- If you are buying, let the agent know when we are coming
How to book
Prices start from £400, including VAT. The exact figure depends on the roof and the package, and you can call 07833 053749 or use the contact form to find out.

Airspace, weather and Northchapel roofs
The wider area around Northchapel has a long history of building, with Petworth House about 4.9 miles south. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
For site and facilities teams at buildings such as Northchapel Community Primary School, thermal images can show where wet insulation sits under a big flat roof. Take an older house close to The Parish Church of St Michael: 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.
