What is a pitch pocket (pitch pan)?

A pitch pocket, often referred to as a pitch pan, primarily serves to seal around roof penetrations. This feature is essential in roofing applications where pipes, vents, or other fixtures pass through the roof membrane. The purpose of the pitch pocket is to create a waterproof barrier that prevents water from seeping into the roofing system around these penetrations. Typically made of metal, a pitch pocket is designed to funnel and manage the flow of water, usually filled with a sealing compound or thermal plastic to enhance its waterproof qualities.

Understanding the significance of pitch pockets is crucial for roof installation and maintenance, as improper sealing can lead to leaks and water damage. The other options do not accurately describe the function or purpose of a pitch pocket. Decorative features, specific types of materials, or frameworks for support are unrelated to the sealant function that a pitch pocket provides in terms of protecting the integrity of a roof.
