It looks like the roof pitch is pretty low. In fact, I am not sure it meets the 3:12 requirement of shingles. You'd want to choose a metal roof that is approved by its manufacturer on the pitch of your roof. As far as weight ... standard shingles weight from 275 - 425 pounds per square while steel roofing weighs from 80 - 125 and aluminum weighs from 40 - 80. Metal is a very low weight way to go.

I have a 20 year old Oak Grove double wide. Original one layer of shingles still in place. I am concerned about the weight of metal an possible heavy snow loads will collapse the roof. Would prefer using metal but can roof with shingles if necessary. Please advise the safest way to approach this.

+1 Normal thought train to think of metal as heavier given it better durability and performance, but, as Todd points out, its actually much lighter in the end. With that pitch, you are going to need to run Standing seam and while it is permissible with most to install over 1 layer of shingles, I prefer to tear off the roof in entirety.
