If underlayments had a race: which one would cross the finish line last?

Anyone else notice they’re a pain to remove if you ever need to do repairs, though? That’s my only gripe.

That’s exactly why I’m on the fence with peel-and-stick. I get the appeal - no leaks, even in the worst weather. But man, when I had to patch a section after a tree limb came down, that stuff fought me every inch. Ended up spending more on labor just getting it off than I did on the new shingles. For my money, I’ll stick with a good synthetic underlayment on most of the roof, and just use peel-and-stick where it really matters (eaves, valleys, low spots). The cost adds up fast if you go full coverage, and if you’re planning to stay in the house long-term, repairs are almost inevitable.

- Totally get what you mean about the removal - it’s like that stuff’s welded on.
- I had to redo a valley last year and it took ages just scraping off the old peel-and-stick.
- Honestly, I’d rather use it just in trouble spots too. Full coverage feels like overkill unless you’re in hurricane country.
- Synthetic underlayment is way easier to deal with if you ever need to get back under there.
- Plus, if you DIY, your hands will thank you later… trust me.

Peel-and-stick is like the marathon runner who refuses to quit... even when you want them to. I had to pull up a section around my chimney last fall (first time ever doing anything like that), and it was a total pain. I thought I could just peel it up in strips, but nope - half of it stayed stuck to the decking, the rest came off in little shreds. Ended up spending more time with a putty knife than I did actually fixing the leak.

I get why people use it in valleys or around skylights, but doing the whole roof? Not for me, especially in our climate. I’m in the Midwest, so we get some storms, but nothing like the coast. I went with synthetic underlayment for the rest and honestly, it was way easier to handle. Didn’t rip as much, didn’t stick to everything, and my hands weren’t a mess by the end of the day.

Funny thing - my neighbor swears by old-school felt because he says it “breathes better.” I don’t know if that’s true or just nostalgia talking, but after wrestling with peel-and-stick, I’d take anything that doesn’t require a chisel to remove.

If underlayments were in a race, peel-and-stick would definitely be dragging its feet at the finish line... but maybe that’s the point? It just doesn’t want to let go.

That’s the classic peel-and-stick headache right there. It’s a beast to remove, especially after a few years baking in the sun. Around chimneys and valleys, it’s great for ice damming, but I agree - using it across the whole deck in the Midwest is probably overkill. Synthetics are lighter, faster, and way less sticky on the hands. As for felt “breathing better,” it technically does, but it also tears if you look at it wrong. I’d rather deal with a little less “breathability” than have to patch wind rips every spring.

Peel-and-stick is a nightmare to get off, no argument there. I’ve had to chisel it off a deck that was only five years old, and it felt like scraping old gum off concrete. The stuff does its job, but man, you pay for it later if you ever need to do repairs. I get why folks use it in trouble spots - chimneys, valleys, low slopes - but I’m with you: full coverage in the Midwest seems like overkill unless you’re really worried about ice dams every winter.

Synthetics have come a long way. I remember when they first started showing up and everyone was skeptical - now it’s hard to find a crew that wants to mess with felt unless the budget’s super tight. The weight difference alone is huge, especially if you’re working solo or with a small team. And yeah, felt might “breathe” a bit more, but I’ve seen it turn into confetti after one good windstorm. Is a little extra breathability worth the hassle of patching or replacing sections every spring? I’m not convinced.

One thing I’ve noticed, though - synthetics can get slick if there’s any dew or frost. Had a buddy take a nasty spill last fall because he thought he could walk it like old 30# felt. Anyone else run into that? I guess every underlayment has its quirks.

Curious if anyone’s tried those newer “hybrid” underlayments? Supposedly they combine the best of both worlds, but I haven’t seen enough jobs with them yet to know if they’re worth the extra cost. At the end of the day, I’d rather spend my time fixing actual leaks than fighting with a putty knife or chasing wind-blown felt across the yard...

I hear you on the peel-and-stick - once it’s down, it’s basically part of the house. I had to demo a section last year (tree limb punched through), and getting that stuff off was a workout I didn’t sign up for. It does seal things up tight, but yeah, if you’re not in an area with serious ice dam issues, it feels like using a sledgehammer for a thumbtack.

Synthetics are my go-to these days, mostly because they’re lighter and honestly just easier to handle. But you nailed it about them being slick. I’ve nearly gone skating myself on a frosty morning - definitely not something you want to mess around with at 20 feet up. Some brands claim their “grip” is better, but I haven’t noticed a huge difference.

As for the hybrids, I’ve only seen them on a couple green roofing installs where moisture management was a big deal. They seemed promising - more grip than straight synthetics, supposedly better breathability - but the price tag made me wince. If they hold up longer and make repairs less of a pain, maybe they’ll catch on, but right now I’m still watching from the sidelines.

Peel-and-stick is a beast to remove, no doubt. I had to patch a section after a solar install went sideways, and it felt like I was chiseling out part of the roof itself. I get why folks use it in tough climates, but for most jobs, it’s overkill and a pain if you ever need to get back under there.

Hybrids are interesting - I’ve only used them once, on a living roof project. They handled moisture better than synthetics, but the price made me double-check the invoice. Not sure they’re worth it unless you really need that breathability. Synthetics are still my default, even if they’re a bit like walking on ice some mornings.

Peel-and-stick is brutal if you ever have to go back in, I’ll give you that. Had to replace a skylight last year and it was like peeling up old gum in the sun - just a mess. I get why people use it for ice dams, but for my regular shingle roof, I’d rather deal with something I can actually remove without swearing. Synthetics are slick, literally, but at least you don’t need a crowbar to get them up. Hybrids? Never tried them - price alone scared me off.

Man, I feel this in my soul. I tried to patch a leak near my chimney and that peel-and-stick fought me every inch. Ended up with half of it stuck to my gloves. Synthetics are slippery as heck, but at least you don’t need a heat gun and a prayer to get them off. Hybrids look fancy, but my wallet says nope.

Peel-and-stick is like wrestling a sticky octopus, I swear. I tried it once on a patch job and ended up with more on my hands than the roof. Synthetics are easier to handle, but I always worry about them sliding around before the shingles go on - especially on steeper slopes. Hybrids look tempting, but the price tag makes me wince every time. For my old ranch house, I just stick with basic felt and cross my fingers during storm season... not perfect, but at least it doesn’t glue itself to everything in sight.

Peel-and-stick definitely tests your patience, especially in the summer. I tried it on a dormer repair last July - by the time I got it lined up, half of it was stuck to my gloves and the other half was wrinkled. Not my finest hour. Synthetics are a lot lighter and easier to roll out, but I’ve had them bunch up on a 10/12 pitch when the wind picked up. Had to tack it down every couple feet just to keep it from sliding off before the shingles went on.

Felt’s cheap and familiar, but I’ve seen it tear if you’re not careful walking on it, especially after a rain. Still, for basic jobs or if you’re on a budget, it gets the job done. Hybrids look solid, but yeah, that price tag is rough - hard to justify unless you’re doing a high-end install or need extra protection.

If I had to pick which one would “finish last,” I’d probably say felt, just because it doesn’t hold up as long in bad weather. But for ease of use? Peel-and-stick is in its own league of frustration...

Peel-and-stick in the summer is a whole different beast. I remember trying to get a strip down on a porch roof when it was pushing 90 degrees - felt like wrestling with flypaper. Ended up with more of it on my forearms than the actual roof. I get why folks like it for ice dam areas, but for a full roof? Not unless I’m getting paid by the hour.

Synthetics are my go-to these days, but you’re right about the wind. I had a roll take off like a kite once - neighbor’s kid thought it was hilarious. Learned to keep a hammer and a pocketful of cap nails handy after that.

Felt’s kind of like that old pair of jeans - comfortable, but you know they’re not gonna last forever. I’ve patched more than one spot after a rainstorm softened things up. For quick jobs or sheds, though, it’s hard to beat the price.

If we’re talking which one limps across the finish line last, I’d probably agree with you on felt. But for sheer aggravation? Peel-and-stick wins that race every time...

Peel-and-stick can be a hassle in the heat, no doubt. But have you tried any of the newer self-adhered membranes that use recycled content? They’re not perfect, but I’ve found they’re less sticky-messy and a little more forgiving if you’re aiming for a greener build. For me, the biggest headache is still felt when it rains - just turns into mush. If you’re open to it, there are some eco-friendly underlayments that hold up better and don’t have the same wind issues as synthetics. It’s a few extra bucks, but worth it for peace of mind and less landfill waste.

I hear you on the felt turning to mush - been there, done that, and had to replace a whole section after a surprise summer storm. I tried one of those recycled-content membranes last year on my shed roof, and honestly, it was way less of a sticky mess than the old-school stuff. Still, nothing’s perfect. The synthetics are lighter and easier to handle, but I’ve had them flap around in high winds before the shingles went on. Sometimes feels like you’re picking the least annoying option rather than the best one.

Sometimes feels like you’re picking the least annoying option rather than the best one.

That’s exactly how I felt staring at the options in the hardware store - like, which one will make me swear the least? I went with felt because it was cheap, but after a week of rain, it looked like a soggy tortilla. The synthetic stuff sounds tempting, but does it really stay put if you’re not shingling right away? I’m half convinced my next roof will just be a tarp and some wishful thinking...

Felt’s like that old friend who shows up when you’re broke - reliable until it rains sideways. I’ve seen more than a few jobs where the felt just gave up after a storm or two, especially if the shingles didn’t go on right away. Synthetic’s definitely grippier and shrugs off rain better, but I’ve had it flap around if the wind picks up and it’s not fastened down well. Honestly, nothing’s perfect, but I’d take the synthetic over a tarp any day... unless you’re into blue roofs, I guess.

I’ve always wondered if felt would even make it halfway around the track if we’re talking about a real race. Every time I’ve had to patch up with felt, it’s like a countdown until the first gust of wind or sideways rain. But then, with synthetic, I’ve seen it bunch up if you don’t get enough cap nails in, especially on steeper slopes. Has anyone actually had synthetic last more than a couple weeks uncovered, or is that just marketing hype? I’m still trying to figure out which one’s less of a headache when you’re stuck waiting on shingles.

Felt’s like that friend who promises to help you move, then bails when it starts raining. I’ve had it blow off in a light breeze - super annoying. But yeah, synthetic isn’t perfect either. I left some uncovered for almost a month (thanks, backordered shingles) and it held up, but only because I went wild with cap nails. Still, I’d pick synthetic for less stress if you’re stuck waiting... just budget for extra fasteners.

I get the frustration with felt, especially if you’re dealing with unpredictable weather. But honestly, I’ve had just as many headaches with synthetic underlayment, especially on bigger commercial jobs. The wind resistance is better, sure, but only if you’re using a ton of fasteners and making sure every seam is tight. I’ve seen crews get a little too confident with synthetic, thinking it’s bulletproof, and then a gust comes through and half the sheet’s flapping around. That’s a nightmare when you’re managing multiple units and trying to keep everything on schedule.

One thing I don’t see mentioned much is self-adhered underlayment. It’s pricier, but for projects where you know the roof might sit exposed for a while - like when you’re juggling trades or waiting on inspections - it’s been a lifesaver. No worries about wind, and it actually seals around the nails. Downside is it’s a pain to reposition once it’s down, and in hot weather it can get messy, but I’ll take that over chasing blown-off sheets across a parking lot.

I’m in the Midwest, so we get everything from heavy rain to high winds to snow. For steep slopes, synthetic’s fine if you’re diligent with fasteners. On low-slope or flat roofs, though, I’d rather pay extra for something that’s not going to move at all. And honestly, if you’re dealing with insurance claims or warranty issues later, having documentation that you used a higher-grade underlayment can save a lot of back-and-forth.

Felt’s cheap and easy, but I only use it now if I know the shingles are going on the same day. Otherwise, it’s just not worth the risk or the callbacks. Synthetic’s a step up, but it’s not set-and-forget either. Just depends how much hassle you want to deal with if the weather turns on you.

Last summer I got my first real taste of what happens when you trust felt for too long. We had a couple days of pop-up storms in the forecast, but the plan was to finish shingling before anything rolled in. Of course, nothing went as planned - half the tear-off was done when the sky turned black. We scrambled to get the felt down, but by morning, water had seeped through where it wrinkled up and pooled. The callbacks after that weren’t fun.

Lately, I’ve been helping out on jobs where they use synthetic. It’s way lighter to carry up a ladder, which is a win for me, but I’ve noticed if you don’t put enough cap nails or staples, it’ll catch wind and start flapping. One guy on our crew thought he could just tack it every few feet - bad idea. We spent an hour chasing it across a neighbor’s yard.

Self-adhered stuff is expensive, like you said, but when we used it on a complicated dormer job last fall, it stuck tight even when we got hit with a windstorm overnight. It’s sticky as heck if you mess up your line, but at least nothing blew off. If I had to pick the slowpoke in this “race,” felt would be dragging way behind... especially on days where weather’s unpredictable.
