I believe you are referring to an area of the roof called a valley. A valley is formed anywhere the downward slope of two roof surfaces meet.
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
a gable roof is double pitched with vertical ends

Continuous roof systems are called membrane roofing. This roofs are used for buildings and tanks. They are built on flat or nearly flat roofs to prevent leaks and help drain water off.
Purlins are used on double roofs. They effectively reduce the span of the rafters and limit their size to ecenomical sections.
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
That would be a Gable
The top of a gable form roof is the peak. This is the tip of the gable and running back along along the rest of the roof it forms the high point of the whole roof which is called the ridgeline. Some gable roofs have a finial, or decorative spike, at the peak of the gable.
The end of a triangular roof is called a gable edge or end.
A roof with only two sloping surfaces and gables at each end is called a gable roof.
The gable roof, also called a saddle roof, has two planes. To measure, multiply the length times the width of each plane, then add together.
A gable is a type of roof used in architecture. Specifically, a gable room is shaped as an upside down "V". A dutch gable roof is a modified version of the same style roof.
No.
a hip roof is stronger than a gable roof because it braces itself and cannot move from side to side.
Neither is "better" in terms of usefulness or structural efficiency. Hip and gable are primarily responses to design needs. A hip roof is slightly stronger than a gable.
The end of a roof when it is formed into a shape intermediate between a gable and a hip; the gable rises about halfway to the ridge, resulting in a truncated shape, the roof being inclined backward from this level.
Are you thinking about a "gable"?
