You can install a long lasting metal roof over existing shingles as long as there is only one layer of shingles on the home and the substrate and existing shingles are level. It is not advisable to install the metal over two existing layers of shingles. You will need to put a layer of 30# roofing felt down over the shingles before installing the new metal roof. If the roof is uneven and solid you can add wood strips on top of the roof on 16” centers to attach the metal to.
