The dichotomous nature of installing metal above an existing shingle roof needs many steps. We will analyze these steps in greater fine detail to help determine if retrofitting the metal roof over and current asphalt shingle roof is definitely an innovative idea.
There are several things must consider before determining to install a metal screen roof over an existing concrete shingle roof.
