The gable roof, perhaps the most basic shape, is said to have evolved from the earliest roofs, which were rudimentary structures of twigs or logs leaning at angles to form a triangle hut. A gable is made up of two sloping sides that meet in the middle of a building and slope at the same angle. Over the body of a building, it will appear as a symmetrical triangle. In North America, this is the most prevalent type.
A cross gabled roof is a little more intricate than a gable since it has two gable portions that meet at an angle. Each gable roof’s ridges should be perpendicular to each other, and the height, length, and pitch of each gable in a cross gabled roof should be identical, just as the slopes on a gable are.You may find more details view this link.
Another typical kind is the simple hip roof, which is sometimes known as a hip roof. The hip roof has two slopes at identical angles that meet in the centre of the building, similar to a gabled roof. The ends, on the other hand, are not flat. A hip roof, on the other hand, has four sloped sides so that all of the outside walls are the same size. Hip roofs are preferable over gable roofs in high-wind or hurricane-prone areas because they provide superior protection. A pyramid hip roof is similar to a simple hip roof, but it has four equal triangular sides that meet in the middle, as the name suggests.
A cross hipped roof combines the benefits of a cross gabled roof with the extra benefits of a hipped roof. A building with all outside walls at the same height can have a cross hipped roof. It’s like if you took two hipped-roof buildings and joined them perpendicularly. A valley is the section of the roof where the two roofs meet.
