Ventilation definitely helps, but sometimes underlayment quality really is the issue. I've seen cases where even perfect airflow couldn't save cheap materials. Always worth checking moisture first, but don't rule out product quality entirely... sometimes you do get what you pay for.
"sometimes you do get what you pay for."
Couldn't agree more. I've inspected roofs where the homeowner swore ventilation was perfect, but the underlayment still failed prematurely. Moisture checks help, sure... but if the product's flimsy, you're fighting a losing battle from day one.
Yeah, that's a tough one... I've had similar experiences myself. Thought I was doing everything right—good ventilation, regular checks—but still ended up with issues way sooner than expected. Makes me wonder if manufacturers are overly optimistic with their lifespan claims? Either way, you're definitely not alone in this frustration. Hang in there, sounds like you're doing your best to stay ahead of it.
Honestly, I get the frustration, but I'm not entirely convinced it's always the manufacturers overselling lifespan. Sometimes it's just the unpredictability of real-world conditions—humidity spikes, temperature swings, or even minor installation quirks. When I moved into my place, I found out the previous owner had installed premium underlayment but skipped sealing some edges properly... talk about facepalm moments. Maybe it's less about lifespan claims and more about how unforgiving these materials can be if everything isn't spot-on? Just a thought.
Yeah, I see your point, but honestly, manufacturers do tend to hype things up a bit. Sure, real-world conditions can be brutal—humidity, temperature swings, and all that—but shouldn't these products be designed with those factors in mind? I mean, it's not like we're installing flooring in a climate-controlled lab or something.
When I bought my place, the underlayment was supposedly "premium" too. But after just a couple years, it started feeling weirdly uneven in spots. Turns out the previous owner had done everything right (at least according to the inspector), yet it still didn't hold up as promised. So yeah, installation quirks definitely matter, but sometimes even when you follow all the rules, stuff just doesn't last as long as advertised.
Maybe it's a combo of overly optimistic marketing and real-world unpredictability... either way, it feels like a gamble every time.
