Calculate roof area (length × width × slope factor), divide by 100 to get squares. Each square needs 3 bundles of standard shingles. A 1,500 sqft footprint with a 6:12 pitch equals about 1,680 sqft of roof area, or 17 squares (51 bundles).
Asphalt shingles: $3.50-7.00/sqft installed. Metal standing seam: $8-14/sqft. Tile: $10-18/sqft. Slate: $15-30/sqft. A typical 1,700 sqft roof costs $6,000-12,000 for asphalt or $14,000-24,000 for metal.
A roofing square equals 100 square feet of roof area. It is the standard unit for measuring and pricing roofing materials. A 2,000 sqft roof is 20 squares. Most contractors quote prices per square.
