Could be partly true, but I think another factor might be that our expectations have changed. Roofing materials today often prioritize cost-effectiveness or aesthetics over sheer longevity. For instance, asphalt shingles used to be thicker with more asphalt content, making them heavier but also more durable. Now, many manufacturers focus on lighter materials for easier installation and lower costs—which naturally impacts lifespan.
Also, building codes and ventilation standards have evolved. Ironically, better insulation and tighter homes can sometimes trap moisture or heat in attics if ventilation isn't carefully planned. That trapped heat shortens shingle life significantly, even if the shingles themselves are decent quality.
Weather could play a role too, sure—but honestly, I feel like roofs have always had to handle harsh conditions. Maybe we're just noticing it more now because replacements seem pricier and happen more frequently than we remember from years ago...
"Ironically, better insulation and tighter homes can sometimes trap moisture or heat in attics if ventilation isn't carefully planned."
This is spot-on. Reminds me of a house I inspected after a big storm last year. The shingles looked decent enough, but underneath was a mess—mold, warped plywood, the works. Turns out the attic had almost zero ventilation. Makes me wonder if homeowners are even aware how critical proper attic airflow is when upgrading insulation or sealing their homes tighter...
Had a similar issue a couple years back. Thought I was being smart upgrading insulation to save on heating bills—felt pretty proud of myself, honestly. Then summer rolled around, and the attic turned into a sauna. Went up there to grab something and nearly melted. Turns out I'd sealed things up so tight, it couldn't breathe properly. Ended up adding some vents, lesson learned... sometimes too much of a good thing isn't great either.
I've heard ventilation blamed a lot for early roof wear, but honestly, I think the roofing materials themselves aren't what they used to be. Could manufacturers be cutting corners these days... or am I just imagining it?

You're definitely onto something here. Have you noticed how warranties keep shrinking too? Used to be you'd get 30 years easy, now they're sneaking in 15-20 year guarantees with all sorts of fine print. Sure, ventilation matters, but I've seen roofs with perfect airflow still fail prematurely. Makes me wonder if it's the materials themselves—maybe recycled content or cheaper fillers? Either way, something's changed, and it's not for the better.
