100 years later, why haven't we found an alternative to asphalt for roofing?

We have found an alternative- steel roofs. Last time I replaced my roof it added 10% to the cost but was expected to last twice as long as asphalt.
I do want a roof on a roof. Solar panels with an air gap shade the roof and reduce A/C use in the summer.
