Wood shake shingle I have been in contact with in the S.E. area are on installed of 12 12 pitch or 14/12 pitch roofs. I don’t know about you, but I wouldn’t want to walk on wood shake for the safety issue, as well as the liabilty issues. If you step and cracked a single this could cause damage that wasn’t there before you were, not to mention you could fall off the roof and be killed like a long time friend who roofed for 22 yrs. He fell 32’ feet during a recent hail storm. Inspecting a wood shake roof where only one nail fasten in a shingle he step on. I will view from the eaves and note it that way.
