What is the primary purpose of copings in roofing?

The primary purpose of copings in roofing is to cover the top of parapet walls. Copings are essential because they protect the parapet from water infiltration, which can lead to structural damage and deterioration over time. By providing a protective barrier, copings help to direct water away from the wall and its underlying structure, thus maintaining the integrity of the building. While copings may also contribute to the aesthetics of a rooftop and can influence the prevention of water pooling to some extent, their primary function is to safeguard the top edge of parapet walls from environmental elements, particularly water. Understanding this is key for those in the roofing profession, as it emphasizes the importance of proper installation and maintenance of copings in ensuring long-lasting roofing systems.
