Pitched roof construction materials.

If your roof pitch declines up to 1 inch vertically for every 12 inches horizontally 1 12 pitch it is a good candidate for rolled roofing as long as you use the concealed nail method of fastening.

Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years. Roof pitch area multipliers. The average roof is 3 000 square feet or around 30 squares.

Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.
