Thermal imaging roof survey in Wonersh, Surrey
Find out what’s going on with the roof before you spend money on it. Thermal roof surveys in Wonersh.
- Moisture around outlets and upstands
- Cold spots on ceilings under the roof
- Stains that keep coming back
DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
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.
Thermal roof surveys for homes and businesses in Wonersh
Thermal imaging is frequently most useful on flat roofs, from small extensions to large commercial roofs. Patterns can suggest where water is trapped under the covering. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we also look from the loft where we can reach it safely. We survey insulated roof spaces, ceilings below the roof and flat roofs, and people most often book us about cold spots on ceilings under the roof and areas losing heat at the eaves and junctions.
Older buildings in small places like Wonersh may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

When you need someone else
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Insulation values or heat loss calculations
- Readings unaffected by sun, shade or reflections
- Structural calculations, which need a structural engineer

What happens if roof problems are left?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. That helps you and your roofer decide what really needs replacing. For older village homes like those around Wonersh, the right replacement materials aren’t always easy to find quickly. That is one more reason to find defects before they become urgent.

Drones, thermal imaging and Wonersh roofs
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
For site and facilities teams at buildings such as Bramley CofE Aided Infant School and Nursery, big roofs are where aerial photos and thermal images show the most at once. For an older house near a landmark such as Wonersh United Reformed Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. Chilworth Manor, about 1.7 miles north, is one of the historic houses in the wider area around Wonersh. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager doesn’t touch the roof itself.

How the survey changes by roof type
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. You are welcome to ask questions while we’re there. Older rural homes like those around Wonersh can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
How to prepare
- Show us where any leaks or stains appear
- Let us know about parking before the day
- Have keys ready for side gates, garages or roof access doors

FAQs for Wonersh
Does a conservation area affect roof work in Wonersh?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will you come out to Wonersh?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
What can thermal imaging tell me about my roof?
A thermal camera shows differences in surface temperature. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
How many surveys have you done?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys.
Can you survey at the weekend?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, ring 07833 053749 or drop us an email.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
