The 3–4” Combo Roof Flashing is designed for reliable performance and easy installation around roof pipe penetrations. It slides over pipes on roof pitches up to 45° and features a rigid black thermoplastic base that resists fading and cracking in harsh weather. A non-fading sealing collar creates a tight seal to help prevent water intrusion while allowing normal expansion and contraction. The flashing is rated for continuous heat up to 180°F, approved for Type B installations, and should not be used with petroleum-based products, which may damage the plastic base or rubber collar.
