- Synthetic’s definitely easier on the back, but you nailed it about the slip factor. I’ve seen a few jobs where folks underestimated that and took a tumble, especially early in the morning when there’s still moisture.
- Durability-wise, I’ve noticed synthetics hold up better if the shingles get delayed—old felt can wrinkle or tear if left exposed too long.

“For me, the lighter weight was nice, but if I had to do it again, I might stick with felt just for that peace of mind underfoot.”
- Curious, did your contractor mention how long the synthetic was rated to last? Some of the newer ones claim 30+ years but I haven’t seen many that old yet. Wondering if anyone’s actually seen one go the distance.
- Synthetic’s lighter and goes down faster, no doubt. But yeah, that slip factor is real—my buddy nearly ate it on a frosty morning last fall. Not fun.
- I’ve seen the same thing with felt buckling if it sits exposed too long. Around here (Pacific NW), rain can show up outta nowhere, so that’s a headache.
- I’m skeptical about the 30-year claims on synthetic. Haven’t seen anything close to that in the wild yet—maybe 10-12 years on some jobs, but most roofs get re-done before then anyway.
- One thing I do like: some synthetics are recyclable now. That’s a big plus for me, trying to keep waste down.
- Curious if anyone’s tried those newer “eco” felts? Supposedly more grip and less plastic content, but I haven’t seen them in person yet. Worth it or just marketing?

I’m wondering the same thing. I keep seeing ads for “eco” underlayments but can’t tell if it’s just greenwashing or actually better. My house is only a few years old (asphalt shingles, pretty standard), but I’m already thinking ahead since we get a ton of rain here too. The idea of more grip sounds good—my neighbor’s roofer nearly slid off last winter. Anyone notice if these eco felts actually hold up better in wet weather, or is it just hype?
I’m right there with you—my place is only a few years old too, and I’m already paranoid about leaks. The “eco” label sounds nice, but I can’t tell if it’s just a new way to charge more. Anyone actually notice a difference in grip or durability when it’s pouring? I’d love to avoid the whole roofer-slipping situation...
I totally get the paranoia—leaks are no joke, especially when you’ve got a newer place and expect everything to just work. I’ve tried a couple of those “eco” underlayments and honestly, the grip was better than the old-school felt, especially when it was wet. Didn’t feel like I was skating around up there, which is a relief. Durability-wise, time will tell, but so far no issues after a couple of nasty storms. The price stings a bit, but if it keeps me off the ground, I’ll take it.
