Abstract: A metal roof retrofit skylight preferably includes a glazing pane, a pane retention frame and at least one self-stick sealing sheet. The pane retention frame preferably includes a bottom leg and a top leg. One end of the bottom and top legs preferably form a fastening flange. The other end of the top is offset from the bottom leg to form a pane space that is sized to receive a thickness of the glazing pane. Each self-stick sealing sheet includes a sealing sheet and release paper. The sealing sheet is applied over a portion of the glazing pane and a membrane roofing material to provide a seal between the membrane roofing material and the glazing pane. An optional condensation collector is installed in a skylight opening in the metal roof. The metal roof retrofit skylight is attached to the metal roof around a perimeter of the skylight opening.
