Thermal roof surveys for homes and businesses in Warnham
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, something you can’t normally tell from the surface. We then check those areas with moisture readings. If you’ve noticed stains that keep coming back and damp around chimneys and parapets, a survey will tell you what’s going on.
In a small place like Warnham, open ground can mean strong wind. A small drone can’t fly safely in strong wind or a downpour, and thermal imaging works best with little wind. 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.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

How it works
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof can’t be seen, the report says so. The survey typically takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Rural addresses near Warnham can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We check the roof from ground level, from windows and from the roof itself where it’s safe.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Gather any invoices or paperwork from past roof work
- Note where any stains or damp appear
- Keep pets out of the way during the survey

Warnham questions
Do you cover smaller places like Warnham?
Yes, Warnham is covered. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Is Warnham in the area you cover?
Yes, Warnham is one of the places we work. The survey and report are the same in Warnham as anywhere else, and visits run on weekdays and weekends.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We can only inspect what we’re given access to.
How long will you be at the property?
Expect it to take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. The written report follows by email, on the timescale of your package.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access when you book.
Will you walk on the roof?
Only if it is safe. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
What this survey can’t tell you
We only report what can be seen safely on the day, so there are some things a survey cannot cover:
- An energy rating for the building
- Whether the deck or roof structure is strong enough
- Proving moisture from the images alone
If in doubt, call 07833 053749 or use the contact form and we’ll point you to the right survey before you book. What our survey covers.
What we check
- Flat roofs
- Loft conversions
- Insulated roof spaces
- Commercial roofs
- Pitched roof slopes
- Ceilings below the roof
Different roofs, different checks
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We combine a visual check of cracks with the thermal images around them.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. Wet boards can show as temperature differences on the images.

What else we do in Warnham
Thermal roof surveys around Warnham
If your survey includes the drone, the flight is checked against the Drone Safety Map first. If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
For site and facilities teams at buildings such as Warnham CofE Primary School, thermal images can show where wet insulation sits under a big flat roof.

Tips that help
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
- Make sure the loft can be reached safely
- Talk to us about the weather when booking
- Keep dated photos of any marks on ceilings
If the images suggest moisture that can’t be confirmed, we’ll say what would help next, such as electronic leak detection or opening up a small area.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps often appear after work in the loft.
Common roof problems in Warnham
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
These are some of the problems a survey can pick up:
- Water getting in at parapets and stacks
- Moisture around outlets and upstands
- Possible trapped moisture under a flat roof covering
- Ceilings that feel colder in places
If you live in an older home near The Parish Church of St Margaret, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from above or with a thermal imager helps.
