As long as it's a planned raid and not a random encounter. Monsters tend to stay away from towns. The Inn should catch fire too with you waking in a blazing room. You only have a few seconds to grab your equipment and get out. Actually, that's probably a bit too harsh losing everything in a panic. I think the fire could be good though.
Also, it would be a good point to make the hero decide: Defend from the roof with ranged combat, fight melee inside, or escape for yourself. Or if you're in league with the Orcs, you can help plan the raid.
Each direction would open different story arcs:
Inside, you would be pitted against the Orc Liutenant who escapes to fight another day.
On the roof you go up against a bizare winged beast who eventually leads you to a mysterious mountain cave.
Running for your life destroys the inn causing key Orc characters to survive and Human characters to die.
It's probably getting a little too complex story-wise, but works well in theory.
