[Cob] Weatherproofing a cob bench (yewberry at wavecable.com)

[Andrew John Martinson]

I'm very curious about the roof over your cob wall.  You obviously have a ridge beam spanning the two (or more?) posts, and rafters to support the sheathing/roof shakes.  How else is the roof supported?  Are their cross supports that run perpendicular to the vertical posts, which span the width of the roof, from rafter-end to rafter-end?  

Thanks,
Andrew
