Southwire 996 Neoprene Roof Flashing 2.5 Inches

Product Description

The SOUTHWIRE 996 is a neoprene roof flashing designed to create a weathertight seal around pipe penetrations through roofing assemblies. Neoprene construction provides flexibility and resistance to UV exposure, ozone, and temperature cycling, making it well-suited for outdoor rooftop installations. At 5 pounds, the flashing offers durable mass while remaining manageable for single-trade installation. The 2.5-inch sizing accommodates standard pipe diameters common in HVAC, plumbing, and electrical conduit applications. Licensed plumbers, HVAC technicians, and roofers typically install this component as part of a code-compliant pipe-through-roof assembly.

This roof flashing is used wherever a pipe, conduit, or vent stack penetrates a roofing surface in residential or light commercial construction. Typical applications include exhaust vent stacks, gas flue pipes, refrigerant line sets, and electrical conduit exits through flat or sloped roofs. The neoprene collar conforms to the pipe and compresses against the roof deck or membrane to prevent water intrusion at the penetration point.

Key Features

• Neoprene construction resists UV, ozone, and outdoor temperature extremes
• 2.5-inch pipe size accommodates common HVAC, plumbing, and conduit diameters
• Flexible collar design compresses to form a weathertight seal at roof penetrations
• Durable 5-pound construction suitable for long-term exterior installation
• Compatible with sloped and flat roofing assemblies

Compatibility

Designed as an OEM-style replacement or new-installation roof flashing for 2.5-inch pipe penetrations in residential and light commercial roofing assemblies.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified roofer in accordance with local building codes and applicable sections of the International Plumbing Code or International Fuel Gas Code. Ensure the pipe and surrounding roof surface are clean and dry before seating the flashing collar. Do not overtighten any clamping hardware, as this may deform the neoprene and compromise the seal. Inspect the surrounding roofing membrane for damage before completing the installation.
