Hello Can your metal roof be placed on existing asphalt shingles. Thank you

Every roofing project has separate considerations but it is not unusual for many residential metal roofs to be installed over a layer of old shingles. The low weight of metal is a factor in this and, unlike asphalt shingles when they are installed as a second layer, it usually does not affect the warranty.
