The Metal for a Hip Roof calculator computes the metal roof materials for a pyramid hip roof based on the dimensions.
INSTRUCTIONS: Choose units and enter the following:
Metal for Pyramid Roof (m): The calculator returns:
However, these can be automatically converted to compatible units via the pull-down menu.
ECONOMY: This calculator provides two numbers of panels. The first (nP+) is a high number with no reduction in the number of panels based on reusing panel leftovers for additional sections (see graphic). When smaller sections are cut out of a panel of maximum length, it is possible in many cases to use the residual (leftover) for another section. This maximum number assumes that a full panel will be used for each section and therefore provides the maximum number of metal panels needed. The second (nP-) number of panels is lower, because it assumes that cuts making the hip ends will produce leftover pieces that can also be used (see diagram).
A Pyramid Hip Roof is a special case of a hip roof where 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 can be defined by a span, pitch and overhang (see diagram). These calculators compute the area, hip ridge lengths and materials required for a pyramid hip roof.
The roofing materials to cover a pyramid roof include:
A pyramid hip roof is geometrically a square based pyramid. The surface area and four hip ridge lengths can be computed using simple trigonometry using the span, including overhang and the pitch.
The photograph shows two sheds located in Colonial Williamsburg, Virginia that have pyramid hip roofs.
A hip roof is basically a rectangular trapezoid volume has regular trapezoids in the front and back and triangles on the sides. The bottom and top rectangles are centered, form parallel planes and separated by the height.
An addition of the TO parameter (default of 3") s added to the following dimensions.
It's better to have too much and have to cut it, than not enough.
