Thermal roof surveys for homes and businesses in Mark Cross
A thermal survey can point to places where heat is escaping through the roof. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. The report shows the images and explains what they may mean. It isn’t an energy rating or a heat loss calculation. We survey loft conversions, pitched roof slopes and insulated roof spaces, and the problems we’re asked to look at most are wet insulation beneath the membrane and areas losing heat at the eaves and junctions.
Villages like Mark Cross often stand in open country, where wind can be strong. A small drone cannot fly safely in high wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
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 Mark Cross
The wider area around Mark Cross has a long history of building, with Wadhurst Castle about 3.2 miles east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, 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.
Take an older house close to St Marks: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

What we do, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take an hour or two for a house, or half a day or so for a commercial building. For a village or hamlet like Mark Cross, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We check the roof from the ground, from windows and from the roof itself where it’s safe.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there is safe access.
- The report sets out the images, what they suggest and what we recommend.
Getting ready for the survey
- Leave side gates unlocked
- Keep pets inside or away from the areas we’re looking at
- Gather any invoices or paperwork from past roof work

What we look for on each type of roof
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.
Loft insulation
Insulation often gets moved during work in the loft. The camera can show where it no longer covers the ceiling.

Why it’s worth a survey now in Mark Cross
Wet insulation under a flat roof does not dry out on its own while the covering stays on. Over time, it insulates less well and can harm the deck. Finding the wet areas sooner keeps the work smaller. Where a roof is exposed, as many are in small places like Mark Cross, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, which starts from £400, including VAT. We can help you choose the package that fits what you need to know.

Common roof problems in Mark Cross
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there’s a clear difference between inside and outside.
It’s worth booking a survey if you’ve seen:
- Water that travels before it shows
- Possible trapped moisture under a flat roof covering
- Damp around roof outlets and upstands
- Damp patches with no obvious cause
Take a building like Mark Cross Church of England Aided Primary School: big roofs are where aerial photos and thermal images show the most at once.
Choosing a roof surveyor
- How they plan to inspect the roof safely
- How much experience they have with roofs like yours
- When you will get the report
- Which limits apply to the survey
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Use the report as a baseline for later checks
- Check from ground level or a window, never by climbing
- Don’t switch the heating off ahead of the visit
- Talk to us about the weather when booking
Once we have been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, alongside what we recommend. Premium reports are sent the same day.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
FAQs for Mark Cross
Do you cover smaller places like Mark Cross?
Yes, Mark Cross is covered. Our area covers London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Is my home in Mark Cross listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.
How long will you be at the property?
Expect it to take between one and two hours at most homes, and longer for a large or complex roof. You will then get the report by email, on the timescale of your package.
Is thermal imaging good for finding leaks?
It’s a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. Where it cannot be pinned down, the report suggests a next step, such as electronic leak detection.
What’s in the report?
A report with photographs, explaining the condition of the roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Do you use drones?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
