I swear I looked like I’d wrestled a porcupine after laying it out.
That static is no joke—synthetic always leaves me looking like I stuck my hand in a socket. I’ve seen felt just disintegrate if it gets wet before shingles go on, especially in humid spots. Synthetic’s tougher, but yeah, it’s pricier and not exactly “green.” I’ve checked out recycled-fiber underlayments, but they’re either hard to find or cost more than the shingles themselves. If anyone’s found something that holds up and doesn’t break the bank, I’m all ears.

That’s my hang-up too—synthetic lasts, but the eco side bugs me. Has anyone tried those paper-based underlayments? I heard they’re more sustainable, but I’m not sure how they hold up in wet climates. Any real-world experience?
I’ve seen a few jobs where folks tried those paper-based underlayments, mostly in milder climates. They’re definitely greener, but honestly, in wet or humid areas, they can get wavy or even break down faster than felt or synthetic. Had one client near the coast—paper underlayment started to curl after a couple seasons of heavy rain. If you’re somewhere with a lot of moisture, I’d be cautious. Anyone else notice that, or did I just see a bad batch?
Title: Which Holds Up Better Over Time: Felt or Synthetic Underlayment?
- Seen the same thing with paper-based stuff, especially after big storms or a few months of humidity. It just doesn’t bounce back once it starts curling.
- In my experience, felt’s a bit more forgiving than paper, but still not great if you’ve got standing water or a slow leak. It’ll soak up moisture and eventually rot out, especially on low-slope roofs.
- Synthetics—at least the decent brands—hold up better in wet climates. They don’t absorb water, and they’re less likely to tear if you’re walking around after a storm. I’ve had to patch a lot fewer leaks since switching over.
- Only downside with synthetics is they can get slippery when wet, so watch your step if you’re up there after rain.
- One job near the Gulf—felt underlayment lasted maybe 6 years before we started seeing soft spots. Swapped to synthetic, and it’s been solid for almost a decade now. No curling, even after a couple hurricanes.
- Price-wise, synthetics are more upfront, but I think you save in the long run by not having to replace it as often.
- Paper might be fine for dry climates or sheds, but anywhere with real weather, I’d skip it.
- Haven’t seen a “bad batch” issue—just seems like paper isn’t made for serious moisture.
If you’re coastal or get heavy rain, synthetic’s probably worth the extra bucks. Just my two cents from patching up storm damage over the years...
- Just went through this debate myself—my house is in a pretty rainy spot and the old felt underlayment was looking rough after maybe 8 years.
- Ended up going with synthetic for the new roof. Price stung a bit, but I figured it’s better than dealing with leaks every few years.
- Only thing that threw me off was how slick it got when the crew was working after a drizzle…one guy nearly took a slide.
- Haven’t noticed any issues so far, but honestly, I’ll be happy if I don’t have to think about my roof again for a decade or two.
- If you’re somewhere dry, maybe felt’s fine, but around here, synthetic just seems less headache.
