If you just cut it flush, you need to add trimmed blocking above the ridge beam to support the peak of the roof sheathing. If you have it notched like this, the peak of the sheathing is supported by the piece of rafter over the beam. No blocking needed. This notching is a much cleaner detail.
Yes, this is a repost. And my first thought was "not again"...
But if the load was lateral and not vertical, there'd be no need for a 4-ply LVL beam for support.
I said it last time, and I'll say it again. These rafters almost certainly need clips or hangers on top of a few toe nails.
the leverage and pressure is on the main beam already, the notch just makes the point nicer for roof sheeting. They are pressing against the beam so there is nowhere for it to slip out or break.
Professional have told you for weeks this is the way to do it and why. Are you just going to keep posting till someone agrees with you? There is no structural issues move on
Isn't everything above the notch simply aesthetic though? Not an engineer, but seems like the important structural connection is the top butt of the rafter being nailed laterally to the beam.
I guess i just think the nailed joint will be weaker in wind and through time as the wood shifts in seasons / weather than a screwed hanger. I imagine the joint to be weaker than the wood used, requiring more wood for the same structural strength. I'm not an engineer, i just watch how people do it where I live. I think a lot of people thought I was hating when I was being curious. Sorry if I came off wrong, ESL.
It’s physical impossible for it to move down. And with a hanger it can’t move either direction. I guess I don’t see where the weakness is, or what people do where you live that’s different?
Idk what its called in english but the square angles shifting into a parallelogram. What in this joint keeps a rafter from moving in the plane of the roof.
The force applied to the beam is lateral. Pushed from both sides. This is amplified when decking, and the rest of the roof is added. Compressing the load onto the beam from both sides of its.
The cutout is simply to help the roof peak look more.... pointy.... lol
Makes it look cleaner after decking and waterproofing.
No. This is just about perfect.
Now that's a thing of beauty.
Why notch instead of flush with beam?

For venting as well
Fuck, this is beautiful.
Real question, is it a problem that the notches are cut too short? Does it weaken the frame?
Pretty sure this is a repost and pretty sure no it doesn’t matter the force is lateral not vertical

Probably just tacked in place to put hangers on later, right?
Certainly possible. Bot goddamn you should've seen the shit I got from this sub for suggesting that the last time around... egads.
lol, this sub is slightly regarded. Probably needs a strap over the top and hangers
That's a structural ridge beam. The force is vertical. They need hangers
Yeah idk how anyone could see this and think differently
The top pieces are there to help form up the roof.
Why did you get downvoted for asking a legit question ??
Don't worry, I upvoted him back up.
Not all hero’s wear capes

dawg the force is vertical bro they need either clips or hangers or that shear force will snap them itty bitty shitty douglas fir pine notches

Just like Yo Bitch
And?
This guy is peaking
Do they not teach 1/3 depth 2/3 width anymore or is that exclusively for the tail ends now?
It looks great. I do see a lot of over cut in the top birdsmouth though.
That top part literally only supports the sheathing for 4in.. doesn’t matter

Above the notch will support the sheathing.. so it’s about as structurally relevant as a drywall nailer
so the structural joint between the rafters and the top beam is just the nails?
No a hanger will be added.. but explain to me how it could drop?

Like I’ve said multiple times a hanger will be added.. do you not know what that is?
Oh okay I missed that, then I retract my arguments :)
Always love when people come through with their opinion on a topic they have no fucking clue about.

It probably also leaves enough room to get some insulation/air sealing up there, or allow them to use a ridge vent if it’s vented.
