Thatís a good question; you would think that metal for the most part would out last the plastic vent cover by far and a few years ago that may have been true, but with the improvements they have made with plastic materials itís hard to truly say.
I would suspect the life expectancy of the plastic vent cover would be determined on the extreme weather conditions it had to endure, quality of the plastic used and location.

And David
I personally would still arch the last few feet of the flex vent piping above the termination point (vent cover) this will help prevent any possible chance of water running back into flex piping in the event of water intrusion. Just a thought.
