The illustration shows J-molding and flashing details around a window in metal or vinyl siding. Two upper views show a modified head J molding before and after installation over the window, with an end tab bent down to overlap the side J molding. Drip cap flashing is positioned above the window head, against the sheathing. The lower view shows flashing extending under the bottom end of the side J molding and lapping over the top of the siding piece below to direct water outward.
