Roofs with pitches of 6:12 are the maximum, not unusualplace. Fine stability among water and snow run-off and simplicity of access.
Any pitch above 9:12. These roofs may also require greater fasteners, and those steeper roofs are very difficult to stroll on.
Many houses are constructed with a steep pitch due to the fact the angled shapes are appealing to th eye. Building an excessive pitched roof charges a bit greater because of the vertical perspective method the roof span is longer and greater substances are required to construct it.
