Thermal Roof Survey in Hunsdonbury
Thermal imaging to find moisture and heat loss patterns in a roof across Hunsdonbury, with drones and thermal imaging where they help. Get in touch for a price.
- Areas of a flat roof that may hold water
- Leaks that are hard to trace
- Cold spots on ceilings under the roof
Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Check from ground level or a window, never by climbing
- Talk to us about the weather when booking
- Keep a record of when stains appear
- Take photos of stains as they appear, so we can compare
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
About our thermal roof survey in Hunsdonbury
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it’s colder outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. If you’re worried about wet areas near outlets and upstands and heat escaping through the roof, we can find out what’s behind it.
In a small place like Hunsdonbury, open ground can mean strong wind. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
Nothing in the report is left vague: if work is needed, the report says so clearly.

DIY checks: what’s safe
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Drones, thermal imaging and Hunsdonbury roofs
With Much Hadham Palace about 4 miles north, Hunsdonbury sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
Take an older house close to St Francis Chapel: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

What else we do in Hunsdonbury
What happens if roof problems are left?
Once insulation under a membrane is wet, it tends to stay wet. Over time, it insulates less well and can harm the deck. Finding the wet areas sooner keeps the work smaller. Older cottages and farmhouses around Hunsdonbury can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
To find out what your survey will cost, call 07833 053749 or use the contact form and tell us about the roof. We’ll confirm the figure before booking.

How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take an hour or two on an ordinary house, and about three to four hours for a commercial roof. Rural addresses near Hunsdonbury can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- 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.
Preparing for the visit
- Mention any parking restrictions on your street
- Unlock side gates and any roof access doors
- Gather any invoices or paperwork from past roof work

Your questions about thermal roof surveys in Hunsdonbury
Do you carry out roof surveys in Hunsdonbury?
We do. The survey and report are the same in Hunsdonbury as anywhere else.
Is my home in Hunsdonbury listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will thermal imaging find my leak?
It’s a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source can’t be confirmed, we will say what could help next, such as electronic leak detection.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
What insurance do you have?
Our cover is professional indemnity plus public liability.
Common roof problems in Hunsdonbury
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there is a clear difference between inside and outside.
These are some of the problems a survey can pick up:
- Cold spots on ceilings under the roof
- Moisture around outlets and upstands
- Leaks far from where the stain appears
- Damp that repairs haven’t cured
If you look after a building such as Hunsdon Junior Mixed and Infant School, a drone or thermal camera can show a large roof in a single visit.
