    Hi everyone.

    So this storm created a new noise for me. Water leaking and sizzling on the stove. We have not really had a storm so it must be something from new install. It is leaking at the ceiling flange. I am thinking it is following he pipe down. Are you suppose to seal the storm collar

    The storm collar should be liberally coated with silicone where it meets the Class A, then smoothed with your fingertip. Depending on the pitch of your roof, you might need to silicone underneath it so that it's sealed to the flashing cone as well. Steeper pitched roofs have a propensity for rain splashing up under the storm collar & getting past the flashing cone.

    You are correct. I put some stove tape up there and it got a lot better. The wind I think was getting under the flashing. It is a flat roof. I had 2 leaks the storm collar and flashing. I will silicone it once the rain stops. Thanks
