Sculpted Utility with Enduring Presence

This lead flashing brings a quiet, architectural confidence to the roofline, shaping seamlessly to the surface for an impeccably tailored finish. I love the generous 15-inch base—its broad plane feels intentional, grounding the vertical pipe with sculptural clarity. Pair it with dark architectural shingles to let the metallic patina evolve into a chic, lived-in detail. It’s a functional essential elevated to a refined accent for a truly considered exterior.
