Last summer we needed to re roof a rental house, so after seeing quite a few homes even some new homes with steel roofing I did some research. The major positive was long life, some was warranted for 50 yrs., some was in sheets like barn steel, some was in rectangle shapes that somehow locked together with no exposed fasteners. Biggest negative over conventional shingles was cost, about double for some. Then I remembered going into steel roofed sheds on a frosty morning when the sun was melting the frost off the inside of the roof and it is almost raining in the building. Would'nt the frost collect on the underside of the steel no matter how it is put on or what is under the steel? Where does this moisture go? Is there a way to get some airflow under the steel to take the moisture out? Anyway I did'nt use the steel, but still wonder about these questions. Frank.
