Pyramid Hip Roof Calculator

The Pyramid Hip Roof Calculator has equations and data useful for computing dimensions and materials for a pyramid hip roof with four equal faces. 

The Pyramid Hip Roof functions include:

• Shingles for Pyramid Roof - Computes the number of bundles of shingles and ridge shingles needed for a pyramid hip roof. It also computes the number of roofing nails for both normal and high wind conditions. It also computes the cost of roofing shingles (not ridge) base on a costs per bundle. 
• Metal for Pyramid Roof - Number and length of metal panels, hip ridge trim, angle trim and metal screws.
• Sheathing for Pyramid Roof - 4x8 sheets for hip roof.
• Purlins for Pyramid Roof - Number and length of purlins.
• Underlayment for Pyramid Roof - Underlayment Rolls.
• Pyramid Hip Roof Geometries - Measurements of pyramid component lengths

Pyramid Hip Roof Geometries

A Pyramid Hip Roof is similar to a basic hip roof, except the hips come to a single point and do not form a ridge line.  All four faces create triangular ends (faces) to the roof which are all exposed to rain and snow from above and require roofing material.

The specifications of a Pyramid Hip Roof are defined by the span, pitch and overhang. These calculators compute the area, hip ridge lengths and materials required for a pyramid hip roof.

Roofing Materials

The roofing materials to cover a pyramid roof include:

• 4x8 sheathing
• purlins
• underlayment
• shingles (3 tab, architectural and ridge)
• metal panels and trim

A hip roof is geometrically a square based pyramid.  Based on the span, including overhang and the pitch, the measurements of the surface area and four hip ridge lengths can be computed. 

Metal roofs are also common on roofs.  For these, it is important to have a solid material to which the metal panels are screwed.  This typically requires purlins, horizontal boards attached to the roof.
