Flying and imaging in Chelwood Gate
In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. With Priest House about 3.8 miles north-west, Chelwood Gate sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Take an older house close to Chelwood Gate Church: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

Thermal roof survey in Chelwood Gate
Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so we check what it shows with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’re worried about wet insulation beneath the membrane and damp where roofs meet walls and chimneys, we can find out what’s behind it, whatever the roof.
Some older homes in villages like Chelwood Gate are listed or in a conservation area. A look from above or with a thermal imager does not 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.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

How the survey works
The aim of the visit is simple: to see as much of the roof as can be seen safely and record it clearly. Notes and photos go into the written report. The visit typically takes an hour or two at most homes, or half a day or so for a commercial building. Somewhere as small as Chelwood Gate, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Agree roof access with the managing agent if it is shared
- Note where any stains or damp appear
- Have keys ready for side gates, garages or roof access doors

What else we do in Chelwood Gate
Surveys for landlords and agents in Chelwood Gate
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer.
Can I check my roof myself?
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
- The height of the building and how the roof can safely be seen
- Chimneys, valleys, parapets and other details
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Prices start from £400, including VAT.
What to let us know when you contact us
A little information up front helps. Please include:
- Access details, such as a loft hatch or a shared roof
- Your timetable, such as an exchange date
- Any marks or damp showing indoors
- The address and postcode of the property
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
What this survey cannot tell you
In fairness, there are limits to any roof survey:
- What’s inside walls or under coverings, without opening up
- Seeing water directly, as the camera shows temperature, not moisture
- An energy rating for the building
Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we’ll tell you before you book. What our survey covers.

How the survey changes by roof type
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
Common questions in Chelwood Gate
Is my home in Chelwood Gate listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you carry out roof surveys in Chelwood Gate?
Yes, Chelwood Gate is within the area we cover. We survey roofs across London and South East England. You can ring 07833 053749 or email us with the address and a few details.
Will thermal imaging find my leak?
Thermal imaging can help, alongside other checks. The results depend on conditions on the day. Where it can’t be pinned down, the report suggests a next step, such as electronic leak detection.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Is thermal imaging useful on pitched roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and can’t tell you, and back them up with a visual inspection and moisture readings.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Is it a structural engineer’s report?
No. We’re roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
