What is the most commonly used pitched roof assembly in commercial strip centers?

The most commonly used pitched roof assembly in commercial strip centers is the ridgepole and rafter system. This method involves a horizontal ridgepole that runs along the peak of the roof and supports the rafters, which are sloped beams that extend down from the ridgepole to the outer walls of the structure. This configuration provides effective drainage for rain and snow, contributing to the longevity and durability of the roof.

Ridgepole and rafter systems are favored in commercial settings for their strength and efficiency in construction. They allow for easier installation and can accommodate various roofing materials, making them versatile for different architectural styles. Additionally, this roof assembly can enable superior ventilation and energy efficiency, important considerations for commercial buildings.

In contrast, other roof assembly types such as truss and beam, flat panel and support beams, and arch and purlin systems may be used in different contexts but are not as prevalent in commercial strip centers due to their specific design characteristics and applications. Truss and beam systems, for example, are often used for larger spans but can be more complex and costly. Flat panel designs typically do not offer the same aesthetic appeal or drainage benefits as pitched roofs, while arch and purlin systems, though structurally effective, are less common for the
