Selkirk components on the roof
Chimney raincap termination
The Sekirk flue rain cap is a domed stainless steel cap that prevent rain entry.
The Storm Collar is designed to fit on the round chimney pipe just above the roof flashing. The upper edge of the Storm Collar should be water proofed with non-hardening silicone caulking to prevent any water from leaking between the Storm Collar and chimney pipe.
NOTE: Storm Collar is not required with Seldek flashings.
Tall cone flashing
Flashings are used to seal the opening where the chimney penetrates the roof and to divert rain and snow down from the roof and away from the chimney system.
