The DuraTech Storm Collar is used to seal off the Roof Flashing where the pipe is coming through the top of the flashing. The Storm Collar is required for any roof penetration. The Storm Collar will fit around the outside of the pipe and sit over the flashing, preventing rain and weather from entering the roof. Seal around the storm collar and chimney pipe with high temp silicone. Note: Choose the size of the storm collar based on the inside diameter of the chimney pipe.
