2.Attach the storm collar over the flash- ing joint and apply sealant between the storm collar and vertical pipe.

To seal the roof hole, and to divert rain and snow from the vent system:

•Attach a flashing to the roof using nails, and use a non-hardening mastic around the edges of the flashing base where it meets the roof.

•Attach a storm collar over the flashing joint to form a water-tight seal. Place non-hardening mastic around the joint, between the storm collar and the vertical pipe.
