Thanks everyone. Yes, I thought that creating a sloped plane on top of kickers may be a solution. And yes I don't think when the parapet was installed/added that anyone thought about the issue (sufficiently).
Is there any concern of the snow accumulating at base/valley of slope?
Anyone have any good (retrofit) solutions to prevent/limit snow drifts against a parapet?
(Even though it summer thought I would shake things up with a winter related question:)
