This is from the New Hampshire gov't website which links to the IBC. R802.3 Framing details. Rafters shall be framed to ridge board or to each other with a gusset plate as a tie. Ridge board shall be at least 1-inch (25 mm) nominal thickness and not less in depth than the cut end of the rafter. My concern is, what does a potential home buyer do? If the builder doesn't know the code, and the inspectors don't enforce the code, where does this leave the buyer?
@Jrfstad It leaves the buyer in a heap of trouble. For over 16 years I've sold an inexpensive checklist at my AsktheBuilder website that shows homeowners how to find the BEST BUILDER in their area in less than 90 minutes. I don't know what else to do.
Why aren't the ridge boards equal to or greater than the depth of the rafters? That's code. WI UDC Comm 21.27 (4) (b)2. "The ridge board shall have a depth at least equal to the length of the cut end of the rafter abutting it." Curious as to how the rough inspection went.
@Jrfstad Remember, local governments can modify the code. I'm not the builder on this job, it's just a location near me. You'd have to come up here to NH and talk with the local inspector to see how the inspection went.
@Jrfstad I caught that too. But upon further analysis, I'd guess that a 2x6 would be adequate for a common, making a 2x8 adequate for a ridge (maybe a 2x10 on a pitch this steep). Hence, anything greater than the 2x6 would not need full bearing. The larger framing size is probably to create more insulation cavity.
However, one courts trouble by using an analytical approach to a prescriptive requirement. The inspector would have every justification to shoot it down.
thanks tim I'm gonna start putting valley rafters in my house this afternoon because of this video, They should make roof super strong so that it doesn't fall down any more.
@mrd999 Steve is a fantastic carpenter. Wait until you see the video I'm about to tape tomorrow or later this morning. Many more rough framing videos will be shot soon to show off how good Steve is. Do you live in central or southern NH? That's his territory.
@starlite528 That's a fantastic question. I'll bet you can figure it out by yourself if I give you this clue. If you were to put a straightedge on the TOP of the rafters and sild it down, where do you anticipate the tip of the straightedge would contact the valley rafters. :->>>>> Isn't that interesting? You have to think in three dimensions.
Nice video Tim! Your tips are really nice! I have probably learned as much about building and such in my lifetime as my father. Thanks! I bet that person in the Black Truck was wondering why someone was up there filming. LOL Thanks again!
@Bassfanatic94 The person in the truck was Steve the builder / carpenter and his ace #1 helper Kevin. They didn't see me on the roof right away, but they did see that someone had taken down the barricade and "broke into" the house.

@stothek2 Uh, if they don't already exist in your current roof, you have much bigger issues.

Thanks for showing this. My question is: why is there a lip where the rafters meet the 'beam' ?

@AsktheBuilder Tim, I'm sorry to be slow, but this is new to me, and I don't get it, even with your clue. What is the purpose of the lip? Thank you!

@siameezerlady That's already been asked in other commets. Please always read ALL comments before posting. Saves lots of my time.

So, how do you derive the angles and lengths of each valley rafter?
Are the valley rafters on 16" or 24" centers so that the plywood roof sheeting will break on the center of the rafters properly?
Do you think that you could show how to calculate the length and angle of a simpler "common" rafter (including the "birdsmouth" cut)?

Interesting. Looks complicated to lay out.
Thanks!

good video Tim,
Hard to find any old fashioned stick built roofs anymore, mostly all truss systems. takes some real carpenter skills to do it that way.
