Found this written on the back of a shingle:
Who says you don't need math in the "real" world?
Here's the daily update:
It is VERY hard to get the nails out of the 2x4's without damaging the brick behind. The nails are masonry nails (threaded) and so they grip the brick. If you try to pull them straight out, they pull the brick out with it, leaving a huge chunk.
We discovered that "unscrewing" them from the wall was the best option, using our vise-grips and a LOT of elbow grease. First, you must "free" the head of the nail... an old chisel worked well to chip away the wood around the nail head. Then, grip the nail in the tip of the vise grips, as tight as you can get. Slowly twist and pull the nail straight out. This only leaves a small hole.
