Replacing rubber with metal on roof

[Account Closed]

I'm currently rehabbing a rental property. I have a upper roof and lower roof. It's a very old house(1900)  Both roofs are leaking and it was recommended to me that a should replace the rubber roof with metal. Has anyone had any experience with this. Is it better than rubber. I imagine so because of the material. It is definitely more expensive so is it worth the cost. Looking forward to the feedback
