I hear you on the Texas sun just destroying everything. I tried doubling up felt on a shed roof a few years back, thinking it’d buy me some extra time before I got around to shingles. Didn’t really help—edges curled up, and the wind just made it worse. Ended up with leaks anyway, and honestly, it was more work for nothing.
I’ve messed with both the cheap felt and some of those synthetic rolls. The synthetics looked promising at first—super light, easy to roll out—but after one summer, they started cracking and curling too. Maybe they’d last longer up north, but here? Not seeing much difference.
My neighbor’s got a metal roof with just one layer of underlayment, and his place is holding up fine. Makes me wonder if all this fuss over underlayment is worth it when the real battle is against the sun and heat. At this point, I’m leaning toward spending less on underlayment and more on whatever’s actually going to be exposed long-term. Just seems like none of them are built for our kind of weather...
That’s been my experience too—felt or synthetic, neither one stands a real chance against the Texas sun. I’ve patched up more than a few roofs where the underlayment just gave up after a couple summers. Honestly, I’ve started thinking of underlayment here as more of a “get you through install” thing, not long-term protection. Metal roofs seem to shrug off the heat way better, and if you’re spending money, might as well put it toward what’s actually facing the elements every day. The sun here just eats everything alive... no magic fix I’ve found yet.
I hear you on the Texas sun—nothing like watching a brand new underlayment start curling up before the paint’s even dry on the fascia. I’ve seen synthetics hold out a little longer than felt, but honestly, it’s a race to the bottom either way once July rolls around. Metal roofs definitely seem to take the punishment better, and at least you’re not redoing the underlayment every few years. Still, I wish there was something that could actually last more than a couple seasons... maybe in another decade?
I’ve been battling the same thing for years—felt, synthetic, peel-and-stick, you name it. The Texas heat just eats everything alive. I went with a “premium” synthetic last time thinking it’d buy me a few more years, but by the second summer, it was already looking tired. Maybe it lasted a bit longer than the old black felt, but not by much.
Metal roofs are tempting, but the upfront cost is no joke. I did the math and, for my place, it’d take at least a decade to break even compared to just redoing shingles and underlayment every few years. Plus, my neighbor’s metal roof sounds like a drumline during hailstorms—kind of funny until you’re trying to sleep.
Honestly, I wish someone would invent an underlayment that could handle this sun without turning into potato chips by August. Until then, I’m just patching as needed and keeping a close eye on the attic for leaks. If anyone ever finds something that actually lasts, I’ll be first in line... but I’m not holding my breath.
I hear you on the Texas sun—mine’s not quite as brutal (I’m in central Oklahoma), but it still cooks everything. I tried a high-temp synthetic last time, thinking it’d be the magic bullet. Nope. By year three, it was curling at the edges and brittle in spots. What’s worked best for me so far is layering: I put down a basic synthetic, then a peel-and-stick just along the eaves and valleys. It’s not perfect, but it seems to slow down the damage where leaks usually start. Still, nothing I’ve tried has really “won the race” against the heat. Just feels like a game of buying time.
