If you’re brave, you can buy a tube of butyl sealant. It’s like Play-Doh for grown-ups. You squish it into cracks. It works great for tiny screw holes. Feel like a superhero? That’s the sealant fumes talking.
But here’s the catch: walking on a metal roof is dangerous. It’s slippery when wet. It’s slippery when dry. It’s slippery when you even think about rain. One wrong step and you’re sledding off into your flower bed. Your azaleas will not catch you gently.
Also, metal roofs expand in the sun and shrink at night. If you patch it on a scorching afternoon, the patch rips apart by midnight. You fixed a leak and created a confession-worthy mess.
