Is It Just Me or Do Underlayments Never Last as Long as Promised?

"Sometimes it's less about the material itself and more about how well it's put down..."

Couldn't agree more. Had a job last year where we pulled off synthetic that was barely five years old - it was flapping loose in spots because the staples weren't spaced right. Meanwhile, my uncle's barn has felt that's pushing fifteen years with zero leaks. Makes you wonder, is it really the material or just sloppy installation that's causing most of these early failures?

"Makes you wonder, is it really the material or just sloppy installation that's causing most of these early failures?"

Definitely installation. I've seen cheap felt last decades because the installer knew what they were doing - proper overlaps, tight staples, and no shortcuts. On the flip side, I've had premium synthetic underlayment fail after just a few years because someone rushed the job. Good materials help, sure, but they're worthless if the workmanship isn't there...

Yeah, installation matters a ton, but it's not always black and white. I've seen quality installs still fail early because of unexpected moisture issues or poor attic ventilation. Good workmanship helps, but sometimes other factors sneak in...

"Good workmanship helps, but sometimes other factors sneak in..."

Yeah, totally agree with this. When we bought our first place, the previous owners had just redone the roof - looked great at first glance. But within two years, we had leaks popping up because the attic ventilation was basically nonexistent. Learned the hard way that even a solid install won't hold up if moisture and airflow aren't managed properly. It's always something...

Ugh, I feel your pain. We had a similar issue - brand new shingles, looked awesome, but whoever did the underlayment must've been daydreaming or something. Two winters later, surprise leaks. Homeownership is basically just advanced troubleshooting, isn't it? Hang in there...
