Summum Pro 6" Storm Collar XL

Extended Flange Weather Seal for Roof Flashings — Model SC-6SCXL

Ensure a permanent, watertight roof penetration with the official Summum Pro 6" Storm Collar XL (Model #SC-6SCXL). Precision-engineered in Canada from heavy-gauge 304 stainless steel, this extra-large storm collar installs directly above your roof flashing to deflect wind-driven rain, melting snow, and ice away from the penetration joint. Featuring an expanded conical skirt designed specifically for steep-pitch flashings, metal roof profiles, and vented flashing boots, the XL storm collar creates a durable, weather-tight counter-flashing seal that will never rust or deteriorate.

Summum Pro Storm Collar XL Technical Dimensions & Profile

Installation Tip: Install the Storm Collar XL directly above the cone of your roof flashing, leaving an approximate ¼" to ½" gap above the flashing top to allow convective ventilation. Seal the top collar contact band around the outer chimney casing with high-temperature silicone sealant (rated for 450°F+ exterior use) to form a permanent watertight barrier.
