The Shingles for a Hip Roof calculator computes the number of standard and ridge shingles for a hip roof based on the dimensions.
INSTRUCTIONS: Choose units and enter the following:
Hip Roof Shingles (sA): The calculator returns the following:
Note: these can be automatically converted to compatible units via the pull-down menu.
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. Ridge shingles are used on the top ridge and on the hip ridges. This algorithm also accounts for a double row of shingle on the bottom drip edge.
The number of roofing nails is based on the two factors, one for normal wind conditions and one for high wind conditions. For normal wind, the algorithm uses 348 nails per 100 ft2 based on the nailing patter shown below. For high wind conditions, the algorithm uses 522 nails per 100 ft2 based on the nailing pattern below.
The Roofing Shingles Cost Survey list the observed price of a bundle of shingles. A bundle is equal to roughly (33 1/3 ft2) or one third of a roofing square (100 ft2). The survey includes a date, the name of the store, and the five price points for shingles: economy, low, median, high and premium.
One should use the pricing for roofing materials that can be bought locally. However, the following prices are for different quality grades of shingles in the United States:
All prices are for one bundle of shingles which cover 33.33 ft2.
