Listeners write in about deepening foundations and ask questions about HRVs, smoothing rough concrete, and finding the right workwear.

And with this style using 2x10s what might be the maximum?

Welcome to the Taunton University of Knowledge FHB Campus at Breaktime. where ... Excellence is its own reward!
got big plans for all that scarp you've been accumlating?
nah, I quit fishing them a long time back and like bass or stripers a lot better.
I would be comfortable up to about 24" with either example, although the 2nd example is stronger due to the vertical orientation of the outriggers using a "dropped" gable truss. To be honest, I seldom see either method any more in my area in favor of just blocks(often only 8' o c !)nailed into the gable wall. SAD!
3-4' depending on snow load requirements

If you're going 3-4' out wouldn't you need to balance that by bringing in the supports further into the main roof structure?
In that first example, the undersupports are acting in compression with the overties in tension so they are the ones extending back up in
Welcome to the Taunton University of Knowledge FHB Campus at Breaktime. where ... Excellence is its own reward!
But the overties provide very little stiffness, so you're depending on the stiffness of the member the undersupports are pressing against, as well as the stiffness of the fascia. Takes very little flex for sag to occur.Probably not so much a structural strength issue as an appearance one.

I am also depending on the fact of the strong subfascia and ridge piece.

Yes, the inboard needs to equal or excede the outboard part.
So the distance of 16" might be for snowload considerations then and say a 36" increment be permitted in low or no loads?
all- In a 4ft. overhang scenario using 2x10s might inverted simpson hangers be necessary or a doubled joist on the inboard?
I would think the rules would roughly match those for a cantilevered balcony (only less load, obviously).

The point of less load seems obvious, but could be arguable.See, when a 2x10 rafter is caled for structurally, then one would presume it is beacuse of load rating required, so that would also limit the overhang of the barge.Did that make sense?

Sort of, I think.

According to my v. old copy of Canadian Wood Frame House Construction, this method is used for gable end projections of less than 16 in.
And in Georgia, 18" was considered the max, though I never saw that codified.George Patterson
I can't believe it ever would be codified. I have lived several places where 24" was the norm

Anything over 16" inches in FL must have engineers stamp.
24 inches (balanced ladder style framing on trusses) is common here, but then all roofs require an engineer's stamp.

24" is pretty common here too. For 12" some of the nastier builders just use the cantelevered roof ply with the subfascia nailed to it.
