I realized that I didn't have any tarps ready to put over unexpected holes in my house.
I've had roof problems and learned a few things about tarping.
* I've seen people lay down tarps and staple them down. This simply doesn't work, as there's not enough support to hold them down in wind.
* I followed others by laying down the tarps and nailing (double-headed nails) strips of lath on top of the tarps to spread out the support. I put them about 4ft apart and all along the edges of the roof so the wind couldn't catch it.
* NEXT TIME! I'm laying down the tarps and holding them down with half-filled sandbags, and just nailing down the lath at the edges. Half-filled/tied sandbags are easy to carry and move around. They don't leave holes in the tarps, so if the tarps aren't left there too long (UV damage), they can be folded up and stashed for later use.
