Thermal Roof Survey in Danehill
We carry out thermal roof surveys in Danehill and the rest of West Sussex. We survey seven days a week.
- Damp around chimneys and parapets
- Possible trapped moisture under a flat roof covering
- Damp that repairs haven’t cured
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older rural homes like those around Danehill can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Check we can get to the back of the property
- If it isn’t your property yet, arrange access through the agent
- Agree roof access with the managing agent if it’s shared

Thermal roof survey in Danehill
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, something you can’t usually tell from the surface. Moisture readings are then used to check what the camera suggests. We survey commercial roofs, flat roofs and ceilings below the roof, and common reasons people get in touch are areas of a flat roof that may hold water and patches of heat loss across the roof.
In a small place like Danehill, 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. If the day turns windy or wet, the visit can be moved.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What a thermal roof survey does not cover
It’s a careful look at the roof, not the whole story. The main limits are:
- Whether the deck or roof structure is strong enough
- Confirming water without moisture readings
- An energy rating for the building

Surveys for landlords and agents in Danehill
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant in advance.
FAQs for Danehill
Do you cover Danehill?
Yes, Danehill is one of the places we work. Every survey there gets the same written report with photos.
Will you come out to Danehill?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Will thermal imaging find my leak?
It’s a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. Where it cannot be pinned down, the report suggests a next step, such as electronic leak detection.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
What conditions are best for thermal imaging?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. Our report notes the conditions and how they affected the findings.

DIY checks: what’s safe
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Check outlets after heavy rain
- Keep the heating on as usual before a heat loss survey
- Note where damp appears and after what weather
- Take photos of stains as they appear, so we can compare
If you’re buying, the report gives you specific points to raise with the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
Thermal roof surveys in Danehill: local notes
Historic houses such as Priest House, about 4 miles north-west, show how far back building in the area around Danehill goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, 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, we check the Drone Safety Map for restrictions before flying.
Take an older house close to The Parish Church of All Saints: thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Anyone responsible for a site like Danehill Church of England Primary School will know that a view from above covers a wide roof far faster than walking it.

Different roofs, different checks
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.
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.
