What does the term 'chase' refer to in roofing?

The term 'chase' in roofing specifically refers to a vertical void or opening designed to accommodate utility lines such as plumbing, electrical, or HVAC systems. This opening allows for the installation and passage of these systems through the building, ensuring they can be routed correctly without compromising the integrity of the roofing structure. It is crucial in the design and construction of buildings to facilitate uninterrupted service and proper ventilation. Having the chase properly constructed and sealed is vital to prevent moisture intrusion and subsequent damage to both the roofing and interior systems of the building. The other choices relate to different aspects of construction or roofing, but they do not capture the specific function of a chase as it is understood in roofing terminology.
