Verge

The horizontal line at the apex of a pitched roof where two slopes meet, closed with ridge tiles, a formed metal capping or a ventilated ridge system. The detail must weather the junction of the meeting coverings and often provides high-level ventilation to the roof space.

The lower horizontal edge of a roof slope, usually projecting beyond the wall face, where rainwater is discharged into the gutter. Eaves details typically include the fascia, soffit, ventilation openings and underlay support to prevent water being trapped behind the gutter.

A board or profile fixed vertically at the roof edge, typically to the ends of the rafters, closing the eaves and usually carrying the rainwater gutter. Fascias are made from timber, cellular PVC, fibre cement or metal.
