Forest Green Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof across Forest Green, with drones and thermal imaging where they help. Get in touch for a price.
- Gaps in loft insulation
- Cold areas below the roof
- Damp around chimneys and parapets
How a thermal roof survey works in Forest Green
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. Typical surveys look at leaks far from where the stain appears and moisture around outlets and upstands, across flat roofs, insulated roof spaces and commercial roofs.
Villages like Forest Green frequently stand in open country, where wind can be strong. A small drone cannot fly safely in strong wind or a downpour, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Should I look at the roof myself first?
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.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.

Your questions about thermal roof surveys in Forest Green
Do you cover Forest Green?
Yes, Forest Green is one of the places we work. The survey and report are the same in Forest Green as anywhere else.
How do I find out if my home in Forest Green is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest.
What can thermal imaging tell me about my roof?
The camera records how the surface temperature varies. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in.
How much does a thermal roof survey cost?
Thermal imaging is included in our Premium Survey, from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
Do you use drones?
Where it’s applicable and safe, yes. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
What happens if roof problems are left?
Buyers get extra information from thermal images that the eye can miss. Finding hidden moisture before exchange gives you facts to raise with the seller. Older and listed buildings around Forest Green may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all with VAT included. The price for your roof depends on its size, access and what you need to know.
Why us?
- Surveys on any day of the week
- Independent findings on the roof’s condition
- A report with photographs
- Over 5,000 surveys carried out

What a thermal roof survey looks like in Forest Green
An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
For an older house near a landmark like Holy Trinity, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from above or with a thermal imager helps.

Landlord and commercial surveys in Forest Green
Landlords and letting agents in Forest Green book surveys as well as householders. A written report with photographs gives you a clear record of the roof, useful for planning maintenance.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or email us with the addresses.
What happens on the day
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes about 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. Older rural homes like those around Forest Green can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it’s safe.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- For a flat or shared roof, check access with the freeholder or managing agent
- Clear the way to the loft hatch
- Dig out any old roof reports or invoices

Advice
What we cannot see
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Proving moisture from the images alone
- The condition of timbers we can’t see
- A structural engineer’s assessment
If in doubt, phone 07833 053749 or email us and we’ll recommend the right survey. The full list of what we check.

Do you need a thermal roof survey in Forest Green?
Some owners book because the rooms under the roof feel cold. Missing or slipped insulation can stand out as temperature differences, particularly when there is a clear difference between inside and outside.
Signs worth acting on include:
- Water that travels before it shows
- Cold areas below the roof
- Patches of heat loss across the roof
- Wet insulation beneath the membrane
Around Forest Green, as everywhere, small roof faults are simplest to sort before they let water in.
Questions to ask before you book
- Which parts of the roof they’ll actually see
- What follow-up you get after the report
- What experience they bring
- What exactly goes into their report
