Galvanized 4-inch plumber’s pipe flashing
This galvanized plumber’s pipe flashing helps create a watertight transition where a pipe penetrates a steep-slope roof. Built from durable galvanized steel with a wide flange for alignment, it’s designed for 7/12–12/12 roof pitches and a 4-inch pipe opening.
Key Features:
- Watertight Roof Penetration: Helps flash around plumbing/vent pipes to reduce leak risk at the roof deck.
- Durable Galvanized Steel: Metal construction designed for exterior roofing exposure.
- Steep-Slope Fit: Intended for roofs in the 7/12–12/12 pitch range for proper pipe angle alignment.
- Wide Base Flange: Large flange footprint supports positioning and integration with roofing materials.
- No Field Trimming Required: Designed to install without cutting the flashing to fit.

A crisp, architectural finish for every roofline detail
There’s something undeniably refined about well-resolved transitions—this galvanized pipe flashing turns a necessary roof penetration into a clean, intentional architectural moment. The sharp geometry and generous flange read like tailored metalwork, giving the roofline a quieter, more considered finish. Pair it with complementary metal accents—gutter details, chimney caps, or hardware—to create a cohesive exterior story. It’s the kind of behind-the-scenes essential that elevates durability into design confidence.
Choose the 4-inch galvanized plumber’s pipe flashing to seal steep-slope roof penetrations with a clean, durable fit.
