Cathedral Ceiling Framing Questions


I'm building a 8' x 15' workshop. the roof is 8/12. would two 2x10s glued and screwed work as ridge beam? . also each 8' end wall has a 4' window on center. i'm planning to bring a 4x4 support post from beam to a 2x10 header supported by 4x4 trimmers. any suggestions?
I live in coastal northern California

Is the roof spanning the 8' width?
Are you planning on collar ties?
You say Cathedral ceiling - no rafter ties?
Without rafter ties every 4' then you need a structural ridge beam

CA may have stricter regs for earthquakes

Hi,

A single ridge beam is enough. The rafters meet in the same spot. That is what holds them up not the ridge beam. They make Simpson hangers to tie everything together.

I would not put the window there. Put 2 windows in the wall or use sun tunnels for light.

What you are planning will work.

thanks for the replies.
the span is 8' with no ties at all - it's definitely a structural beam.
