Thermal cameras are used for roof inspections to non-invasively detect hidden moisture, insulation issues, and air leaks by visualizing temperature differences, allowing for early problem detection (like water trapped under the membrane) that shows as warmer areas at night, preventing major damage and saving costs. It provides a comprehensive, quick assessment by highlighting hot/cold spots that aren’t visible to the naked eye, making maintenance proactive rather than reactive, especially with drone integration. 

Key Benefits & How It Works:

• Moisture Detection: Water absorbs and holds heat longer than dry materials. After absorbing solar energy all day, wet insulation or saturated areas release heat slowly at night, appearing as distinct warm (bright) spots on the thermal image.
• Non-Invasive: It’s a non-destructive method, meaning inspectors don’t need to cut into the roof to find problems.
• Early Detection: Catches issues like trapped water or failing insulation in their early stages, preventing costly structural damage, mold, and extensive repairs.
• Comprehensive & Fast: Can scan large commercial roofs quickly, especially with drones, offering a complete picture of the roof’s thermal performance.
• Energy Efficiency: Identifies areas of heat loss or gain, helping to reduce energy consumption. 

Ideal Conditions:

• Timing: Often best performed at night or early morning after the sun has heated the roof, but before it’s fully cooled.
• Weather: A clean, dry roof surface with little wind is ideal for clear readings. 

By using thermal imaging, inspectors get a precise map of problem areas, allowing for targeted repairs and extending the roof’s lifespan
