Gable vents are actually counter productive when used with ridge vents. It is better to have ventilation at the soffits which will create a draft drawing in cooler air and exhausting it through the ridge.
Gable vents go on the ends of the house where the peak is. At the top point of the triangle.
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.
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
With either gable vents, soffit vents or ridge vents. The more the better
No.
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.
a hip roof is stronger than a gable roof because it braces itself and cannot move from side to side.
A shingled roof requires ventilation. That can be done several ways. Gable vents, turbine vents, air hawks or ridge vent. It is also important that your soffits are vented to get proper airflow.
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.
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.
Are you thinking about a "gable"?
Labor cost for hip roof would be more then gable. Materials are about the same. Hip roof cost slightly more.
