That is melted siding. This is NOT how to cap off the holiday weekend. My neighbor’s 15-year-old set off fireworks and the result set my house ablaze. Thank somebody that his dad was around and grabbed the hose as quickly as he did. The flames were to my roof. My oldest and I just happened to be standing by the front door when we noticed the smoke.
I’ve never been a prude about fireworks. Until now. Folks, leave it to the professionals please. That shit was scary.
