Yeah, that's pretty much spot-on from what I've seen too. Manufacturers stepping in directly is rare, but when they do, it's usually because something went seriously off the rails. Had a similar situation last year after a big storm—homeowner had major leaks, and turns out the contractor had completely botched the flashing around the chimney. Manufacturer rep actually showed up, documented everything, and got involved pretty quickly. I think you're right about reputation management being a factor... no one wants their brand plastered all over social media with angry homeowners pointing out shoddy work.
Still, for most folks, relying on the manufacturer's warranty alone can be risky. It's usually smarter to vet your contractor thoroughly upfront and make sure they're certified or approved by the manufacturer. That way, if something does go sideways, you've got a better chance of getting support from both sides.
Had a similar issue myself a couple years back—contractor was long gone by the time leaks started after heavy rain. Manufacturer warranty didn't help much either, since it turned out the installer wasn't certified. Learned my lesson the hard way... Now I always double-check certifications and ask around locally for recommendations. Manufacturer warranties are nice on paper, but having someone reliable do the job right from day one saves a ton of headaches later.
Went through something similar when helping a buddy fix his roof last spring. He had a warranty too, but turns out the manufacturer wouldn't cover improper flashing installation—installer issue. People overlook flashing all the time, but honestly, that's where most leaks start. Warranty fine print can be brutal... I'd say always press your contractor about specific installation practices, not just their certs. Good roofers appreciate informed customers anyway, and it helps catch shortcuts before they become nightmares.
Good points about flashing—definitely underrated and misunderstood. But honestly, I think warranties get a bit more flak than they deserve. Sure, the fine print can sting, but manufacturers have to draw the line somewhere. If they covered every installer error, they'd be out of business pretty quick. The real issue is that homeowners often treat warranties like safety nets instead of focusing upfront on vetting their contractors thoroughly. I've seen people pick a roofer purely based on price and then get surprised when corners get cut...
Another thing: even great contractors can have an off day or an inexperienced crew member on site. So yeah, being informed helps, but it's also worth considering third-party inspections or quality checks during installation. Might cost a bit extra upfront, but it beats finding out later that your warranty won't bail you out because of some overlooked detail during install.

Haha, this reminds me of a job we did a few years back. Had a new guy who swore he knew flashing inside-out. Turns out his "experience" was mostly YouTube tutorials... let's just say we learned the hard way that warranties don't cover rookie enthusiasm. Third-party inspections aren't a bad idea—sometimes it's worth paying extra to avoid those awkward homeowner conversations later.
