I get where you’re coming from, but I’ve gotta push back a bit on the idea that coatings are just a lost cause once the deck’s old. I’ve seen some pretty tired wood decks last another five, even ten years with the right prep and a solid elastomeric or polyurea coating—key word being prep. Most of the bubbling and peeling I run into is from moisture trapped in the deck or not letting things dry out enough before coating. Upstate NY’s freeze-thaw is brutal, no doubt, but sometimes it’s less about the product and more about what’s lurking under those layers.
That said, if you’re feeling soft spots underfoot, yeah, that’s a red flag—no coating’s gonna fix rot. But for folks with decent structure underneath, I wouldn’t write off coatings entirely. Just gotta be obsessive about surface prep and maybe accept that it’s a band-aid, not a cure-all. Still beats dropping $20k on a new roof if you can squeeze out a few more years...

That’s pretty much where I’m at too. My place is pushing 30 years old, and the roof deck’s seen better days—lots of patch jobs over the years, but nothing catastrophic yet. I’ve tried a couple different coatings (one was that “miracle” white elastomeric stuff from the big box store, the other was some pricier polyurea my buddy swore by). Both looked great for about a year, then started peeling in spots. Not everywhere, but enough to bug me.
I’ll admit, I probably rushed the prep the first time. Thought I could just sweep off the leaves and slap it on before rain hit. Big mistake. Second go-round, I got out the pressure washer and let it dry for two days, but even then, some spots bubbled up after a rough winter. Upstate NY weather just doesn’t cut you any slack—one day it’s sunny, next day it’s freezing rain.
I do agree with you that if there’s soft wood or rot underfoot, forget it. No coating is gonna save that mess. But if your deck is still solid, these coatings can buy you some time if you’re willing to put in the work. Just gotta keep expectations realistic—like you said, it’s a band-aid.
Honestly, I’d rather spend $300 every couple years than fork over twenty grand all at once. Maybe not perfect, but it keeps the water out and lets me save up for when I really have to bite the bullet on a full tear-off. If anyone has found something that actually lasts more than two winters up here though, I’m all ears...
