What Is a Hip Roof?

A hip roof is a type of roof where all sides slope downward toward the walls. It is more stable than gable roofs and is commonly used in residential and commercial buildings for better wind resistance and durability.

How Hip Roof Measurements Work

Hip roof geometry depends on building dimensions and pitch. The rafters and hip rafters are calculated using basic trigonometric relations based on rise and run.
