“A storm collar is a term used in construction and building industries, particularly in the context of roofing. It is a small, cylindrical or conical-shaped accessory that is typically made of metal or other durable materials. The primary purpose of a storm collar is to provide a waterproof and weatherproof seal around vent pipes or chimneys that protrude through a roof.
When a vent pipe or chimney passes through a roof, there is a potential for water or moisture to enter the building around the opening. To prevent this, a storm collar is installed around the pipe or chimney at the point where it meets the roof. The storm collar is then sealed to the roof surface, creating a watertight barrier that prevents rain, snow, or other elements from infiltrating the building.
Storm collars are commonly used in conjunction with other roof flashing components, such as base flashings and roof boots, to ensure the roof’s integrity and protect against water damage. They are an essential part of roofing systems and play a crucial role in maintaining a water-resistant building envelope.”
