I'm building a simple shed with a gable roof & would like to overhang
the roof (gable side) about 4'. The roof is cement tile. Any thoughts?
I figure if nothing else I can simply extend the top plates on the two
sides over & put in posts but I'm wondering if there's a better (read
4 feet is a bit much, especially with mission tile. You can use a
drop chord end truss (maybe the next one in also) and cantilever
the lookouts, probably 2x6's on 12" centers. I would double the
last common rafter to carry the load of the lookouts.
If you extend the top plates to a post at each side without a
collar tie or joist, I think the load will cripple the overhang.
Keep the whole world singing . . . .

I have a 4' gable overhang with concrete tile without posts & it's been fine
for 20+ years on a 24' span, 5:12 pitch roof. Please note that my timber
sizes are for exposed cedar, so they're bigger than you would use for SYP,
fir, etc. I have a pair of 4x12 top plate extensions & a 4x12 ridge
extension. On those I have 2 sets of exposed 4x8 rafters 24" o.c. & used
3/4" plywood for roof decking. HTH.
