Abstract: A vent pipe cover protective device for a plumbing vent stack having a weatherproofing cover formed substantially of lead material permanently secured over the vent stack. The protective device completely covers the exposed surface of the weatherproof cover so as to prevent access thereto for chewing and consuming any of the lead material by rodents such as squirrels and rats. The upper end of the protective device includes an end piece having apertures such as provided by a screen or mesh material or a drilled plate which are of sufficient size to allow the free upward escape of sewer gas and which are sufficiently small in size so as to prevent, rodents, rats, and other critters such as roaches, birds and snakes from entering into the vent stack itself.
