How a thermal roof survey works in Potten End
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. It helps us see how far water may have spread under the covering, which is hard to judge by eye. Moisture readings are then used to check what the camera suggests. Common reasons to book are water that travels before it shows and wet areas near outlets and upstands, across flat roofs, pitched roof slopes and commercial roofs.
Some older homes in villages like Potten End 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. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

Potten End: your questions answered
How do I find out if my home in Potten End is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you come out to Potten End?
We do. Villages and rural addresses get the same survey as a town house.
Is thermal imaging useful on pitched roofs?
It can show heat loss and some damp, but it has more limits there. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
Will thermal imaging find my leak?
Thermal imaging can help, alongside other checks. 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.
Do I need to be at home?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when booking.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Can you inspect my roof with a drone?
Yes, where applicable and safe. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
What a thermal roof survey looks like in Potten End
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Older houses in the South East often have slate or clay tile roofs, while many later estates have 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 a building like Potten End CofE Primary School: a drone or thermal camera can show a large roof in a single visit.

Signs you need a thermal roof survey in Potten End
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
A survey can pick up problems like:
- Areas losing heat at the eaves and junctions
- Gaps in loft insulation
- Wet insulation beneath the membrane
- Damp patches with no obvious cause
If you live in an older home near Church of the Holy Trinity, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Before booking any roof surveyor
- How long they’ve been surveying roofs
- What the report includes, and whether it has photos
- Whether any drone flown is registered with the CAA
- Whether the inside of the roof is included
Why it is worth a survey now in Potten End
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. For an older or listed building in a place like Potten End, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.
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.
Why us?
- An independent look at the roof
- Drones and thermal imaging where applicable
- 5,000+ roofs surveyed
- 20+ years’ experience
What a thermal roof survey does not cover
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:
- Reliable images in rain, strong wind or on a wet roof surface
- Confirming water without moisture readings
- The condition of timbers we can’t see
