The plot needs rescuing.
He gets in an airplane and flies to Scotland to fix his aunt's roof. I'm not sure why he can't just send her money and hire someone in Scotland to help her. It'd probably be cheaper. Plus, he's a lumberjack. He cuts down trees; he doesn't fix roofs. He's not a roofer, that's a completely different job.

Sometimes people need their roofs fixed. Or, fly across the world to do minor chores for your loved ones.
