No Jerry.... read that again.

He said, "After peeling back 3 layers of asphalt composition shingles, the original roof is cedar shake". That means there are already 4 layers of roof covering!!!

This is something I can tell you about (for sure).... If you install plyboard or OSB over the existing covering (after removal of all 3 layers of composition shingle, you are still left with wood shake) and as sometimes happens, you have a hurricane come through S Carolina and remove your roof, you will more than likely be buying the whole roof yourself (with no insurance coverage due to an improper install).

Don't do it!!!! If you do, we will have to put a contract out on you and have a fellow inspector in SC come over there and whack your pee-pee.
