There are in fact a large number of stamped metal roof styles that fell out of favor over 100 years ago – not because they were not good roofs, but because they cost considerably more than the new, tar-based asphalt shingles that were entering the market. The life-span limitations of the asphalt shingles were outweighed by the much lower price, and so metal fell out of favor as low building cost became more important than permanence. Metal roofs are enjoying a resurgence now that real estate costs are at all-time high and people are seeking high-quality architectural features.
