Skylight in sloping roof details.

With this skylight the glazed section slides as a single leaf and is supported by tracks on the roof itself in the open position. On very steep roofs where the top of the skylight is near eye level a horizontal angle works well for the top side of the well. Typically the top side of the skylight well runs at 90 degrees to the roof slope and the bottom side if splayed is framed plumb see figure 3 20. If the skylight is installed on a low slope roof the curb should be even taller to allow for 8 inches of flashing.

When using manufacturer produced curbs that aren t tall enough the roofing professional will have to extend the curb. See roofing systems for more discussion on steep slope roofing systems. A metal counterflashing for the step flashing that forms the transition from the roof to the rafter is integrated into the pressure bar detail. If you are unsure the skylight manufacturer should provide drawings to indicate minimum curb heights which will allow your builder to calculate how high the top of the slope needs to be to achieve the desired pitch.
