What is a common cause of roof leaks?

A common cause of roof leaks is poor installation or damaged flashing. Flashing is crucial because it is used to direct water away from critical areas of a roof, such as chimneys, vents, and valleys. When flashing is improperly installed, corroded, or damaged, it can allow water to penetrate beneath the roofing materials, leading to leaks.

The integrity of flashing is essential for maintaining a watertight seal; therefore, any issues with it can significantly increase the risk of leaks. Proper installation involves ensuring that the flashing is appropriately fitted, sealed, and overlaps other roofing materials as needed. This attention to detail helps prevent water intrusion, particularly in vulnerable areas.

While improper insulation materials, excessive weight on the roof, and inadequate design of roof pitch can each contribute to roofing issues, they are not the primary or most common causes of leaks compared to the role of flashing. Knowing the importance of flashing and the potential for leaks when it is inadequate underscores the need for thorough evaluation during roof installation and maintenance.
