Question: 1 / 400

What is the primary function of roof flashing?

To provide drainage

To secure the roof

To prevent water leaks around roof joints

Roof flashing is primarily designed to prevent water leaks around roof joints, seams, and penetrations such as chimneys, vents, and skylights. This material acts as a barrier to divert water away from critical areas of the roof where leaks are most likely to occur. It is typically crafted from durable materials such as metal, which can withstand the various weather conditions without deteriorating.

Effective flashing is essential for maintaining the integrity of the roofing system because, without it, water can seep into openings, leading to structural damage, mold growth, and other issues. While securing the roof, providing drainage, and enhancing insulation are important aspects of roofing, the primary function of flashing specifically focuses on water management and leak prevention. This targeted role is crucial in ensuring that the overall roofing system performs effectively and extends its lifespan.
