Re: Post Anchor Question
My understanding is that they are only "sleepers" if not securely and permanently attached to the structure/roof.
Such as when laid in a bed of plastic roof cement.
Once permanently secured/attached, they are no longer "sleepers", they are part of the structure.
If one is concerned about the movement differential between the wood and the plastic roof cement (which is why the plastic roof cement is used, to allow for that movement), then you could put down a bed of plastic roof cement, metal flashing or modified flashing (must be compatible with the plastic roof cement), then another bed of plastic roof cement with the wood "sleepers" on that.
That would allow for an isolation layer between the wood and the roofing, however, it now creates the same problem between the roofing and the metal flashing isolation layer, etc.
