Can I install asphalt shingles over an aluminum roof sunroom - NatalySmGlile - 01-17-2020

This is an existing sunroom built with aluminum roofing panelsWe would like to quiet the rain noise by installing a shingle roof over the aluminumI\'ve considered trying to cover with osb then install shinglesAny ideas would be appreciated.The added weight of osb plus roofing paper plus shingles is a big problem for the aluminum panelsYou had better consult a structural engineerI have a sun room that had an aluminum roofIt was leakingI was up on the roof and nearly fell throughI took off the roof and installed a 2x6 by 12 ft wood roof over a 10 ft room; giving a 2 ft overhangThe roof slope was too low for shinglesWith advise from a roofing supplier, I went with plywood and a two layer roll roofingNo nailing except around the very outside edgePeel and stick roll roofingAdded R19 fiberglass between 2x6\'s and sheet rock underneath.Other related question
