Roofing materials were somewhat based on where you lived. In the later part of the 19th century if you lived near a train depot you had more options. If however, you moved out to the west with limited supplies your roof would be something different.
Wooden shingles, Thatched and slate singles were available during the 19th century. However tin roofing also was available in the later part of the century.
According to Houghtalings Handbook of Useful Information ©1887 the cost of tin for Flat Seam Roofing (20x28 Tin) ranged from $8.00 a box to $23.00 per box. For Standing Seam Roofing you had the same range. Houghtalings then gives a charge to figure out the cost per square which amounts to four sheets in each box.
