Sounds like you've good a solid defensive plan. Be safe! Our son was a woodland firefighter on a type 2 crew for a few years, now he's a Life Flight paramedic, and I guided a hotshot crew into a wilderness fire scene once, as close to wildfire as I ever want to get.
I've seen commercials showing metallic blankets that is fire extinguisher. We should cover the walls and roofs with that material maybe. God bless you Maranatha
