Head Flashing is engineered to protect your mounting blocks and building envelope from water damage. Available for block widths of 5.50", 7.25", 9.25", 11.25", and 16" (primed fini sh only), this Z-metal component is essential for code compliance and warranty coverage. It deflects rain and runoff away from block edges, preventing water infiltration that leads to rot and mold. By integrating with house wrap and siding, flashing maintains your moisture barrier's integrity around penetrations. Manufacturer specifications from James Hardie and Nichiha mandate flashing above any opening larger than 1½"—including mounting blocks. Proper installation extends fixture and siding lifespan to 50 years while reducing ice buildup, gasket failure, and corrosion. (Custom Colors N/A!!!) Show more
