Anyone who claims their underlayment is grippy in all weather probably hasn’t met upstate black ice yet...
That’s the truth. I’ve tried a handful of “slip-resistant” brands over the years, and none of them have lived up to the hype once you get a real frost or that sneaky morning glaze. I’ve had a couple close calls myself—one time I thought I was being smart by using those little foam kneepads for extra grip, but all it did was make me slide faster. Ended up sitting on the ridge, just waiting for the sun to do its thing.
I’m curious, has anyone actually found an underlayment that holds up on a steep pitch when it’s slick out? I keep seeing these new synthetics advertised as “walkable” but honestly, I don’t trust any of them until I’ve seen it in action. Felt always seemed sketchy, but at least you know what you’re getting. The synthetics are lighter and tougher, sure, but they get just as icy.
Also, how’s everyone dealing with the cold snaps? I’ve started pushing my start times back an hour or two in winter, just to avoid the worst of it. It slows things down, but beats risking a broken leg. Anyone still using the old-school granulated underlayments? I remember those being a bit better for grip, but they’re a pain to install and don’t last as long.
I guess patience really is the only thing that works every time. That, and maybe a thermos of coffee like you said. But if someone’s got a legit solution for not skating around up there, I’d love to hear it.
Never found anything that’s truly grippy once the frost hits, either. Those “walkable” synthetics are fine in the dry, but as soon as you get that thin ice layer, it’s game over. I’ve tried tossing down some roofing granules for traction in a pinch—works a bit, but not enough to trust my neck on a steep pitch. Honestly, waiting for the sun or shifting start times is about all I trust. The old granulated stuff was rougher on the knees but did seem to help a little with grip... just didn’t last worth a darn.
That thin layer of frost is a menace, isn’t it? I’ve tried just about every “walkable” synthetic out there, and they all turn into a skating rink once things freeze up. The granules trick—yeah, I’ve dumped a few buckets myself, but like you said, it’s more psychological than practical. I remember one winter, I thought I’d outsmart the ice by laying down some old-school 30# felt with sand on top. It was grippy for about half a morning, then the sun hit and it turned into mush. My knees still haven’t forgiven me.
I will say, the newer “high-traction” synthetics seem a bit better in the cold, but nothing’s perfect. Maybe it’s just wishful thinking, but the last roll I used (can’t remember the brand—blue label?) felt less slick than others. Still wouldn’t trust it on a steep pitch before noon in January. At this point, I just plan my work around the sun and keep my boots clean. If someone ever invents an underlayment that’s actually grippy in frost, they’ll make a fortune...
That blue label synthetic—if it’s the one I’m thinking of—does seem to have a little more bite, but I’m with you: nothing’s truly safe when there’s frost. I’ve seen folks get a false sense of security from those “high-traction” claims, then end up sliding anyway. Honestly, I trust my boots and timing more than any underlayment.
I’ve inspected a handful of roofs after winter installs, and the stories are always the same: someone thought they had it figured out, then one patch of shade or a surprise cold snap turns things ugly. The sand trick is clever in theory, but like you said, it just turns into a mess once the sun does its thing.
If anyone ever cracks the code on a frost-proof underlayment, they’ll be rich for sure. Until then, I just tell folks to work with the weather, not against it. Early mornings in January? Not worth the risk, no matter what’s under your boots.
Honestly, I trust my boots and timing more than any underlayment.
That’s been my experience too. I’ve tried a couple of those “grip” synthetics, including the blue label one, and they’re definitely better than the old felt, but frost is frost. Doesn’t matter what’s under your feet if there’s a slick patch hiding in the shade. I learned that the hard way last winter—thought I was being careful, but one step on a north-facing slope after a cold night and I was on my backside before I knew it. Didn’t break anything, but my pride took a hit.
I get why folks want to believe in a magic fix, especially with how much these new products cost. But for me, paying extra for something that only helps a little isn’t worth it. I’d rather put that money toward better boots or just wait for the sun to do its job. If you’re on a budget like me, timing is everything. No point risking an injury (or a hospital bill) just to finish a job before lunch.
The sand trick—tried that once and it turned into mud by noon. Not worth the mess or cleanup. Maybe if you’re desperate, but I wouldn’t recommend it.
Only thing that’s really lasted for me is patience. Wait until things thaw out, even if it means losing half a day. My roof’s steep enough that any slip could be serious, and honestly, nothing I’ve seen on the market changes that.
If someone does invent a real frost-proof underlayment, I’ll be first in line... but until then, I’ll stick to working smarter, not harder (or riskier).
