Remember: a metal roof can last over 50 years if you treat it right. You just gave it a few more decades of good service. Pat yourself on the back. Then go check your gutters—they’re probably full of leaves and plotting their own rebellion. But that, my friend, is a story for another rainy day.
Now go forth and seal. Your ceiling is counting on you.
