Skylight in sloping roof details.

A metal counterflashing for the step flashing that forms the transition from the roof to the rafter is integrated into the pressure bar detail. With this skylight the glazed section slides as a single leaf and is supported by tracks on the roof itself in the open position. Sliding over roof skylight sliding over roof skylight for larger areas with sufficient unobstructed roof space for the sliding section you should consider a sliding over roof skylight. To achieve the required pitch a curb is usually constructed around the aperture in the roof which will accommodate the slope into it for the skylight to be structurally fixed to.

When using manufacturer produced curbs that aren t tall enough the roofing professional will have to extend the curb. If the skylight is installed on a low slope roof the curb should be even taller to allow for 8 inches of flashing. 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. The pitchglaze is a ce marked roof window designed to be installed in pitched tiled roof applications flush in plane with the tiling line.

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.
