When you can’t slide a standard pipe boot over the top of a penetration—due to electrical weather heads, support stays, or existing equipment—the IPS Retrofit Round Base Flashing is the professional’s answer. Available nationwide through A1A Wholesale Supply, these retrofit units allow for a high-performance seal on metal roofs where traditional installation is impossible.
The “split” design allows the flashing to be wrapped around the pipe and secured with a durable, integrated mechanical closure. Like the standard Water-Tite® line, the retrofit base is highly adaptable, molding easily to the ribs and valleys of your metal roofing panels to stop leaks before they start.
