What is the recommended minimum clearance between pipes and curbs or walls?

The recommended minimum clearance between pipes and curbs or walls is 12 inches. This guideline is important in roofing practices because adequate clearance helps to prevent potential issues such as water pooling around pipes, which could lead to leaks and structural damage over time. The distance also allows for proper installation and maintenance access, ensuring that any necessary repairs can be conducted without obstruction. Maintaining this minimum clearance supports the long-term durability and functionality of the roofing system.
