Which statement correctly describes the relationship between roof steepness and moisture shedding?

The statement that the steeper the roof, the better it sheds moisture, and the longer it lasts is accurate because steep roofs facilitate the rapid drainage of rainwater and melting snow. This is critical in preventing water accumulation, which can lead to leaks, damage, and deterioration over time.

When a roof has a steep pitch, gravity assists in moving water off the surface efficiently. Less water pooling means less chance for moisture to penetrate roofing materials, which in turn significantly extends the lifespan of the roofing system. Additionally, steep roofs can minimize the risk of ice dam formation, a common issue in colder climates where old water or snow may freeze at the eaves, leading to potential leaks underneath the roofing material.

Therefore, the steeper the roof incline, the more effective it is at channeling moisture away and reducing the potential for water-related damage, contributing to a longer overall lifespan.
