I've got a tarp that's approaching 6 years old. I always store it clean and dry. Besides seam sealing, what should be done? How long should the materials last before it no longer repels water?

Theoretically, the material should last indefinitely assuming little or no direct sunlight for extended periods. I have a silnylon tarp I used during my ground-dweller days that is in the neighborhood of 12 years old and it is still going strong. I use it occasionally when I sleep out on the deck. Other than keeping it clean and not storing it wet, I've done nothing in terms of maintenance.

I agree with TrailRunner that they should (or could) last a long, long time. All depends on conditions, how frequently used, how hard/easy you are on your gear. I have known people who could destroy something in 2 days that would last me 2 decades.
That said, one thing to look for is stuff with polyurethane (PU) coatings. There are some silnylon tarps with PU coatings and these can break down over several years just sitting in the closet. You'll notice a distinctive smell and they'll have a somewhat sticky feeling. However, this is my experience from older gear so maybe they're improved over the years.

Not to worry until it starts to fail. If it ever does. I have old tarps still going fine.
Seems your taking good care of it.

I have a 20+ year old GoreTex shell from EMS. The Goretex is still waterproof but the surface fabric has needed a reapplication of a DWR coating (durable water repellant) a few times. This is available in a spray bottle applicator from Nikwax (carried by REI or Amazon). I use the one marketed for clothing, TX Direct, but, they also offer one specifically for Tents and Gear, Tents and Gear Solarproof.
The TX Direct revives the water beading on my coat for 2-3 years per application. I have never used the Tents and Gear product
