What is a common method to inspect a roof for damage?

A visual inspection from the ground or ladder is a common method to inspect a roof for damage due to its practicality and accessibility. This approach allows the inspector to assess the roof’s condition without needing to be on the roof itself, which can be safer and reduces the risk of additional damage during the inspection process. It enables the inspector to look for visible signs of wear or damage such as missing shingles, sagging areas, or debris accumulation.

While inspecting from the roof can provide a more detailed view of the roof's surface, it may not always be feasible due to safety considerations or the condition of the roof. Infrared scanning and ultrasonic measurements are more advanced techniques that can detect underlying issues or moisture, but they require specialized equipment and training, making them less common for general inspections. Therefore, a visual inspection from the ground or ladder remains a widely used method for assessing roof conditions.
