looking at a job for a panel change out.
the existing service wires run over the top of a car port roof with a clearence of approx 40" from the roof to the weatherhead.
hopefully grandfathered in (99% sure) and i can just change load side only.

but i am wondering whats the highest a riser can go? in my wac(washington administative code)book it only requires guy wire support or ridgid support after 26" to bottom of drip loop when striking to the riser,without listing a maximum height the obvious seems like 8' since that is min. vert. from roof.....just never ever seen one that high before.

If this carport is just a pan roof that you can't walk on I would not get to concerned about the height.
I don't think there is really a restriction on mast height but at a certain point physics raises it's ugly head. You might actually be better getting an opinion from the structural inspector.
