Solar and roofing decisions should be made together, not five years apart.
Do not mount solar on a roof with limited life left. Removing and reinstalling an array to re-roof underneath costs real money.
Every mount is a roof penetration. Flashing quality at those penetrations determines whether the array causes leaks.
Standing seam metal allows clamp mounting with no penetrations at all. Tile requires specialized mounts and careful handling to avoid breakage.
Confirm how the solar installation interacts with your roofing workmanship coverage before work begins.
