Hip roofs can be built with almost any type of roofing material, such as shingles, metal, or tiles. They are frequently used in modern architecture, especially for bungalows, ranch homes, and cottage-style homes. Hip roofs are among the most structurally sound of all roof designs.

Why have a hip roof?

Pros: Hip roofs are more stable than gable roofs. The inward slope of all four sides is what makes it sturdier and more durable. Hip roofs are excellent for both high wind and snowy areas. The slant of the roof allows snow to easily slide off with no standing water.

Hip Roof

  • Advantages: The four-way slope makes it much more stable than other roofing types, and allows water and snow to run off with ease. There is also more ventilation and space for an attic.

How is hip and valley roof calculated?

Hip and Valley Factor Formula

For a roof slope expressed as “X-in-12” (rise-in-run), the hip and valley factor is determined by finding the square root of ((rise/run)² + 2) for the slope of the adjacent roof sections. Divide the rise by the run (the run is 12). Square the result.
