Yeah, I was surprised too—thought “composite” meant lighter, but nope. Lugged a few up myself and my back still remembers. I’m with you on the radiant barrier thing... seems like good ventilation does more for attic temps than any fancy foil. Texas heat just finds a way in.
Ha, I totally fell for the “composite equals easy to carry” myth too. Those suckers are dense. My neighbor and I nearly threw our backs out stacking ‘em. As for radiant barriers, I did the foil thing years ago—didn’t notice much change, but adding a ridge vent made a world of difference. Texas attics just want to bake you no matter what you try...
Yeah, the weight of composite tiles really surprised me too. I’d read all the marketing about “lighter than slate” and figured they’d be a breeze, but once you start moving bundles around, it’s a different story. My installer actually had to reinforce a couple rafters just to be safe—those things add up fast on a big roof.
On the radiant barrier topic, I’ve had similar results. Tried the foil stapled under the rafters in my old place, and honestly, the attic still felt like an oven in July. Ridge venting and proper soffit vents made a much bigger impact for us. Airflow seems to matter more than reflectivity, at least in this climate.
One thing I do appreciate about the composites is how they handle hail. We get those spring storms every year, and so far, not a single cracked tile. Asphalt would’ve needed patching by now. Still, if anyone’s thinking about DIY-ing it, definitely plan for some heavy lifting...
Honestly, I kinda wonder if the radiant barrier thing gets oversold. My uncle swears his attic is way cooler since he put one in, but he’s also in a drier climate than me. For us, the airflow made a bigger difference too, but maybe it depends on the house? Also, I’ve seen some composite tiles actually chip on the edges after a couple winters—maybe it’s just the brand? Guess nothing’s totally bulletproof...
Yeah, I’ve noticed the same thing with airflow making a bigger impact than radiant barriers, at least around here where it gets muggy. As for composite tiles, I’ve seen some brands hold up better than others—one job we did last year, the edges chipped after just one freeze-thaw cycle. Seems like nothing’s totally maintenance-free, but I guess that’s roofing for you...
