Install Over Low Slope Torch Down Roof
Q: I have a 1950’s home that is in need of new roof (estimated year left on old, very low slope 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.
A: 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.
