shake roof over plywood
I know that you dont cedar shake over plywood on a house
BUT
I have built a gazebo in the back yard, with the intention to ashphalt roof the roof. I plywooded the octagon roof and started the rest of the railing when (the wife) desided that she now wants cedar shake roof.
It isn't like it has to last 25years or anything but could I use shakes over plywood or do i have to rip off the good plywood to strap the roof????????
Any tips would be appreciated.
And replacing the wife is not one of them

There is an expanded plastic mesh sheeting that is made for the purpose to hold cedar shakes up off of the roof to allow them to dry. It is installed over plywood and roofing felt and under the layers of shakes as you go.
It is a new product, but I saw it on Bob Vila's show recently, so you may have to search around for it.
You can also tack strips of pressure-treated lattice-work size strips under the down edges of the shakes to hold them up off of the roofing felt to dry.
If you install wood shingles or shakes flat on a roof, as you know, they cannot dry out properly and will cup and warp. However, you don't have to remove your plywood roofing.
Where the octagon sides meet, you will probably need to do like the pro roofer did on Bob Vila's show...use a sidegrinder with sandpaper to bevel the overlapping shake edges smooth where they meet to keep from creating an unsightly hump along those ridges.
Good luck!
