Built to a 1\/4 pitch, it accommodates standard residential roof slopes and provides a watertight collar around the vent stack where it exits the roofing surface. Galvanized steel construction resists corrosion in outdoor and moisture-exposed environments. This flashing is handled by HVAC technicians, plumbers, and roofers during vent stack installation or replacement on residential and light commercial jobs. Each order includes 3 units.\u003c\/p\u003e\n\u003cp\u003eThis flashing is suited for use with 5-inch round vent pipes on residential and light commercial rooftop applications. It installs over single-wall or B-vent pipe penetrations on gas appliance venting systems, including furnaces, water heaters, and boilers. The 1\/4 pitch profile matches common roof slopes encountered on standard residential construction. It is typically installed as part of a new venting rough-in or when replacing weathered or failed existing flashing around an active vent stack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch throat diameter fits standard 5-inch round vent pipe\u003c\/li\u003e\n  \u003cli\u003e1\/4 pitch profile designed for common residential roof slopes\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in outdoor installations\u003c\/li\u003e\n  \u003cli\u003eRainproof design seals roof penetration against water infiltration\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 3 units, reducing per-job material runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation flashing for 5-inch round vent pipe penetrations on residential and light commercial rooftop venting systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, plumber, or qualified roofer. Shut off the connected appliance and allow the vent system to cool before beginning work at the roof penetration.
