Costs. Metal roofing will cost approximately $265 to $600 per roofing square or $2 to $6 per square foot for steel or aluminum shingles, $120 to $150 for corrugated steel panels, and $700 to $900 for copper or zinc. After adding installation, a steel or aluminum roof will cost about $500 to $1,000 per square.
The cost of materials for metal shingles ranges from $2.5 â $4 per sq. ft., depending on the manufacturer, and metal they are made from. These shingles typically last 40+ years.While they are not as cheap as corrugated panels, they offer great curb appeal, and superior protection against rain, snow and ice.aterial cost of an R-panel is about $1.10 per sq. ft., and a âlifetimeâ (yeah, right!) asphalt shingle will cost about $1 per sq. ft. In Midwest states, the complete system cost for both types of roofing is fairly equal.
