St Denys Thermal Roof Survey
Thermal roof surveys in St Denys and the rest of Southampton. Surveys run on any day of the week.
- Ceilings that feel colder in places
- Damp patches with no obvious cause
- Gaps in loft insulation
How a thermal roof survey works in St Denys
What a thermal camera can show depends a lot on the weather. A sunny day before the survey, a dry roof surface and little wind all help. Rain, a strong wind or heavy cloud can make the images less clear. We talk through the forecast when booking, and our report notes the conditions and how they affected what we saw. We are often asked to look into ceilings that feel colder in places and areas of a flat roof that may hold water, on commercial roofs, pitched roof slopes and ceilings below the roof.
Places like St Denys can be near small airfields or other airspace restrictions, so every drone flight starts with a check of the Drone Safety Map. Open ground can mean stronger wind, which also affects whether a small drone can fly. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
The Standard Survey adds 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.

Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Keep outlets and gutters clear to stop water sitting
- Note where damp appears and after what weather
- Keep the report to compare against after any repair
- Move stored items away from the loft hatch
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. The less water sits, the less can find its way beneath.
What happens if roof problems are left?
A damp patch that keeps coming back usually has a cause that hasn’t been found. Combining the camera with moisture readings can help find it, instead of trying repair after repair. Homes in smaller places like St Denys can face more weather, so a loose ridge or verge soon lets rain in. Each storm lifts it a little further.

St Denys questions
Is drone flying allowed in St Denys?
It depends on the exact address and the weather on the day. The flight restriction zone around Southampton Airport covers St Denys, 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, and the rest of the survey does not depend on the drone.
Do you cover smaller places like St Denys?
Yes. St Denys is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Will I get photos?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access.
What we cannot see
To be straight with you, there are limits to any roof survey:
- Confirming water without moisture readings
- Whether the deck or roof structure is strong enough
- An energy rating for the building
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you. The full list of what we check.
Roof types and parts we check
- Loft conversions
- Pitched roof slopes
- Ceilings below the roof
- Insulated roof spaces
- Commercial roofs
- Flat roofs
How we price thermal roof surveys
When we price a survey, we consider:
- Whether it is a home or a commercial building
- Chimneys, valleys, parapets and other details
- Any need for thermal images or a drone flight
- Whether you choose the Basic, Standard or Premium Survey
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £400, including VAT.
Helping us price your survey
A little information up front helps. Please include:
- Why you want a survey: buying, a leak, a storm or new work
- The kind of building and roof involved
- Pictures of the roof from a safe spot, if you have them
- Whether there’s a loft hatch, a shared roof or tricky access
A quick phone call is normally the easiest start: ring 07833 053749 or use the contact form. The price is agreed before a date is set.
What we’re asked to look at in St Denys
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
Here are some of the things we see frequently:
- Water that travels before it shows
- Moisture around outlets and upstands
- Missing or slipped insulation
- Areas of a flat roof that may hold water
For businesses in and around places such as Marlands Shopping Centre, a commercial roof can be photographed from above without anyone walking on it.
Choosing a roof surveyor
- What exactly goes into their report
- Their drone registration, if they fly one
- When you will get the report
- Whether VAT is in the quoted price
How it works
We work from the outside in: outside views come first, then the roof space if there’s safe access. All told, expect between one and two hours at a typical home, with bigger or more complicated roofs taking longer. A visit to St Denys is planned like any other: the time, the access and where to park are agreed in advance. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- Check the loft hatch can be reached
- Let us know about parking near the property

St Denys is inside, or right on the edge of, the flight restriction zone around Southampton Airport. If your survey includes the drone, we ask the airport for permission first, and only fly if it’s given.
South Stoneham House lies about 1 mile north-east, so building around St Denys goes back a long way. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. Take a building like St Denys Primary School: big roofs are where close-up aerial shots and thermal images show the most at once.
