Thermal imaging roof survey in Harefield, Southampton
Thermal imaging to find moisture and heat loss patterns in a roof in Harefield, carried out by an experienced roof surveyor. You get a clear written report with photographs.
- Areas of a flat roof that may hold water
- Stains that keep coming back
- Missing or slipped insulation
How it works
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. In a smaller place like Harefield, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Move anything stored under the loft hatch
- Check we can get to the back of the property
- Keep pets out of the way during the survey

How a thermal roof survey works in Harefield
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it is 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. If you’ve noticed heat escaping through the roof and water getting in at parapets and stacks, a survey will tell you what’s going on, whatever the roof.
Even in a smaller place like Harefield, there may be airfields or restrictions nearby, so the Drone Safety Map is checked before any flight. Exposed sites can be windy, and a small drone can’t fly safely in strong wind, while thermal imaging also works best with little wind. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What else we do in Harefield
Leave it or get it looked at?
If a big flat roof may need replacing, knowing the wet areas first is useful. Images backed by moisture readings show where problems seem to be before you spend. With lower homes, common in places like Harefield, there’s little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.

What you can safely check yourself
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
Common questions in Harefield
Does a conservation area affect roof work in Harefield?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is drone flying allowed in Harefield?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around Southampton Airport covers Harefield, or comes right up to its edge. Before any flight there, we ask the airport for permission, and the flight only goes ahead if it’s given. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
Does thermal imaging work on slate and tile roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How does a thermal imaging roof survey work?
The camera records how the surface temperature varies. Those patterns can point to trapped moisture, missing insulation or heat loss. Findings are checked with moisture readings.
Does someone need to be in?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we will agree the details when you book.
Prices for thermal roof surveys in Harefield
The price reflects the time and kit the roof needs. That comes down to:
- Basic, Standard or Premium
- How tall the building is and how easy the roof is to see
- The size of the roof
- How many separate roofs there are, like extensions, dormers and garages
Thermal roof survey starts from £400, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and which survey you book.
Getting in touch
Here’s what helps us most when you get in touch:
- Pictures from the garden or a window, if you have them
- What’s prompted the survey
- Any stains, drips or damp patches you’ve seen indoors
- Dates you’re working to, like exchange
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or use the contact form.
Tips from our surveys
A little preparation and a few simple habits help. Our tips:
- Take photos of stains as they appear, so we can compare
- Remember the conditions on the day affect the results
- Use the report as a baseline for later checks
- Clear leaves from outlets and gutters each autumn
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
What we look for on each type of roof
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Drones, thermal imaging and Harefield roofs
Harefield lies within about 3 miles of the sea, and wind off the sea can be strong. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. About 1.9 miles north-west lies South Stoneham House, a reminder of how long the area around Harefield has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
If you live in an older home near Church of St James, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. For site and facilities teams at buildings like Harefield Primary School, thermal images can show where wet insulation sits under a big flat roof. If you run a business near Marlands Shopping Centre, big, flat commercial roofs are where aerial photos and thermal images help most.
