Sleek Utility for a Cleaner Roofline

This aluminum base tucks neatly into the roofscape, bringing a crisp, architectural polish to necessary vent penetrations. I love the subtle flare of the conical form—an elegant detail that feels intentional rather than purely functional. Pair it with a matching cap and a dark shingle palette for a refined, unobtrusive silhouette. It’s a small upgrade that elevates the finish and reliability of any luxury exterior.
