Streamlined Protection for Clean Rooflines
This sleek galvanized steel step flashing brings a crisp, architectural edge to roof-to-wall transitions, quietly guiding water away while preserving the roof’s silhouette. I love its long, uninterrupted 10‑foot run that keeps lines tidy and minimal. Pair it with charcoal shingles and a graphite counter flashing for a refined, modern contrast. It’s a subtle essential that makes a roof feel tailored and luxuriously finished.
