I believe "watch her roll" refers to observing that which he is burning down. I have heard the term of a fire "rolling" when it is at full blaze. I think that Caleb attibutes the pronoun "her" to the object he is burning, much like you often refer to a ship in that fashion. In the context of this song it seems to me that he is actually burning down a cabin or home, which may just be a symbol of all that is "standing in the way". He references his kids and burying pictures so I take it to mean he is burning down his own empty home and realizes he will likely be caught for doing so. "Can you feel it" I believe refers to both the heat of the fire as well as the gesture of the act of burning something down. He seems to realize he won't be the "cornerstone" or foundation of his family once the act is complete. The line about "little shaken babies" is very poignant and somewhat unsettling. Overall I love this song.

what it says is "little shakin babies and drunkards seem to all agree" so it is trying to show that not just one group of people agree but many different walks of life agree, all the way from little shakin babies to drunkards.

@rokt Yeah with such a good jam from a solid band it was a good long while before I thought much about it. But once I did think about what in the world he meant with the repetitive "watch her roll" that comes around later in the song, I as well came to the conclusion that "her" must indeed be that fire rolling. Certainly didn't seem to be anything specifically about a female or his relationship with a female in this song, but quite the contrary almost everything in the song seemed to be broadly applicable to many different...
