A roof frame is the structural framework that supports a building's roof. It is typically made from materials like wood or metal and is designed to bear the weight of the roof covering, such as shingles or tiles. Roof frames come in various designs, including gable, hip, and flat roofs, each serving different architectural styles and functional needs. The primary purpose of a roof frame is to provide stability and strength, ensuring that the roof can withstand environmental factors like wind, rain, and snow. Properly constructed roof frames also help with insulation and ventilation, contributing to the overall energy efficiency of a building.
