Interesting you mention the freeze-thaw thing—I've seen that too, especially with some of the cheaper composites. It makes me wonder if brand or even batch matters more than folks think. Around here, humidity seems to do a number on the adhesives as well, not just airflow. Did you notice any difference in how the tiles handled expansion and contraction? I’m starting to think routine checks are just part of the deal, no matter what material you pick...
Brand definitely makes a difference, at least from what I’ve seen on jobs. Some composites just don’t flex the same way when temps swing—had one batch last winter that started to cup at the edges, but another brand held up fine. Humidity’s a pain too, especially if the attic’s not vented right. I always tell folks, no matter what you put up there, a quick walk-around after big weather changes is worth it... caught a few loose tiles that way before they became a real headache.

That’s the truth. I thought I could skip the “walk-around” after a storm last fall—big mistake. Found a couple of composite tiles halfway down the yard two days later, looking like they’d tried to make a break for it. I will say, though, my new batch (went with a pricier brand this time) hasn’t budged since. Maybe it’s luck, maybe it’s the extra cash, but I’m not complaining. Humidity’s still a pain, but at least I’m not chasing tiles anymore.
I hear you on the humidity—mine still gets a little funky under there, but at least the tiles stay put now. I went with a mid-range composite last year after my old asphalt ones started curling up like potato chips. Haven’t had to chase a single piece since, even with those wild spring winds. Maybe it’s the install, maybe it’s just better material, but I’ll take it. Still check after storms though... old habits die hard.

That habit never really goes away, does it? I’m with you on the wind—seen too many loose shingles over the years to trust any material 100%. Composite seems to hold up better where I am, but humidity still messes with the underlayment sometimes. Did you notice any difference in noise during heavy rain? Some folks say composites are a bit quieter than asphalt, but I can’t always tell.
