How long do the waterproof qualities of polyurethane last on jackets?

One of my jackets is made of polyester and laminated with polyurethane; I assume the latter provides the waterproof qualities. I assume this laminate eventually wears off from wear and time, right?

No thoughts?

Depends on quality and use. It will often flake when losing steam. Say 10 years. Google for better info.

Exactly so. there is no right or wrong time for its utility to extend.

Good to know the shelf life. Seems like the longevity is substantial for about 10 years. That's better than most technical shells as Gore-Tex wears after a few years and wax cotton requires regular applications.

Haven't owned outerwear with PU but it seems like it will provide decent use.

Well, I had a tent last over 25 years before it started delaminating, a rain jacket I rarely wore last 15 or more... now I prefer to budget those items in 5 year windows.
