Raftered Roofs
Conventional rafters, along with ridges and other structural components of a raftered roof, are a great way to get custom ceiling lines while also allowing for maximum heights and clearances for things like vaulted and cathedral ceilings.
A raftered roof will be a little more expensive when it comes to the labor and materials, but because they can typically be built with common and readily available materials it makes them a solid choice when time is a factor.
Rafters are also often used in conjunction with a trussed roof in what's called 'over-framing' which is framing between multiple sets of trusses in order to have the proper shedding of water. It's is done by using various valleys, crickets and hips.
