A pipe penetrates through roof construction and is sealed with a pipe collar set over a two-pound lead flashing. A one-sixteenth-inch Nervastral 600 sheet plastic seal is adhered using PV30 adhesive and secured around the pipe with a stainless steel gear clamp. Roof penetrations and detailing must be coordinated with the architect.
