That’s spot on about the metal shavings—seen that mistake way too often. I’ve also noticed some crews rush the underlayment step, thinking the panels will cover any sins. Ever run into issues where a bad underlayment job caused leaks even with “premium” panels?

- Seen it more than once. Doesn’t matter how fancy the panels are if the underlayment’s wrinkled, torn, or just plain missing in spots.
- Had a place last winter—brand new standing seam, but water was tracking right through the valleys. Turns out the crew skipped ice & water shield at the eaves. Panels looked perfect, but the ceiling was trashed.
- I’m always skeptical when someone says “the panels will hide it.” They might hide it, but they sure won’t fix it.
Curious—anyone ever see synthetic underlayment fail, or is it mostly the old felt that causes grief?
