I have a 1950’s home that is in need of new roof. (estimated year left on old, very low pitch torch down roof)
I am interested in placing a metal roof on the home and am curious if it possible to install over the existing torch down assuming there are no leaks and sheathing is placed prior to install.
It is possible but you must make sure that the roof you are installing is appropriate for the pitch that your roof has. Generally speaking I am guessing your roof has a low slope which would make a mechanically seamed standing seam metal roof most appropriate.
