The Detail Guy Behind Dry Chimneys

Ninety percent of roof leaks start at details — chimneys, walls, skylights, vents. That's Mario's entire world. He hand-bends custom flashing on site, solders what others caulk, and treats every penetration like the roof depends on it. Because it does.

Before Copperline, Mario spent five years in architectural sheet-metal shops, which is why our chimney cricket work looks as good as it performs.
