How high should the pan of batten seam roofs be turned?

For batten seam roofs, the correct height for the pan to be turned is typically 2 inches. This measurement is essential because it helps ensure that the roofing system can effectively shed water while maintaining structural integrity. A 2-inch height provides a good balance between allowing for adequate water runoff and ensuring that the seams are securely joined to prevent water infiltration.

In the context of roofing, turning the pan to the appropriate height is crucial for performance and durability. A turn that is too low may not adequately direct water away from the seams, leading to potential leaks and water damage over time. Conversely, a turn that is much higher could complicate installation and may not improve water shedding sufficiently. Therefore, the 2-inch specification is a widely accepted practice in the industry for optimal performance in batten seam roof installations. The height allows for enough material to create a reliable seam while facilitating proper water drainage.
