You guys might be interested how roofs are framed in Germany where i live now . there's an english name for it but i can't remember what it' is .they use a ridge beam of solid wood or laminated .stock , the beam is posted up every so many feet depending on the length of the beam. then two more beams are positioned about a third of the way down the slope on both sides . the rafters are notched with a birdsmouth on the ridge beam and on the additional beams as well as on the outside walls . as you know this eliminates any sagging or spreading of the walls as all of the force is downward . no other additional supports like collar ties etc. are used. the reason they do this is because the vaulted area under the roof is always a living space . The rafters are usually 4x material . this may seem like overkill but consider that all roofs have either clay or concrete tiles , which are very heavy . couple that with snow and you have an enormous amount of weight up there .
The Exposed wooden collar ties were not necessary by Code. They used Simpson straps to unitize rafters to ridge beam which is to code. By the way collar ties are insignificant for wall blow out.
Rafter ties are lower 1/3 and affect wall spread. Collar ties are top 1/3 and because they are so high up don't really affect wall spread much but help resist lateral wind loads from pulling the roof apart at the ridge board or ridge beam (if used). Depending on the roof type and engineered design. Yes the original comment is a year old, but just incase someone else was curious.
@@christophermaidment4316, ceiling joists sit on wall plates to tie to bottom of the rafter together. Collar ties MUST be in the upper 1/3 of the rafter per code.
He didn't explain that part well. He did say "directly over". In this video's example, that girder is actually acting like a massive header. I couldn't say how that girder is supported - looks like it's just bolted to the house framing, but I'd have imagined that the girder would need double-2x4 studs supporting it like a post.
How can you build in acathedral roof that will give you a R value of 60? I need to rebuild part of my home with a cathedral ceiling, AND get R 60 insulation. Would closed cell spray foam give me that? Do I need an air gap under the sheathing for some air movement?
You would need to use SIPS panels on top of the framed roof. It stands for Structural Insulated Panels. It comes in various thicknesses to achieve your R value and it is basically a big sheet of insulation sandwiched between to sheets of osb.
Did you ever consider that you don't know enough to not know what you don't know? Keep up educating yourself and you'll avoid problems. Such as these guys passing off formaldehyde saturated products like OSB sheeting, as plywood. (Which can also have formaldehyde, but less.)
Did you say collar ties are installed in the lower one third of the rafter? I think you mean the upper one third of the rafter. The lower one third is for rafter ties.
You mention and show 5/8 OSB with clips for roof. Then at end you show plywood. OSB is cheaper in price, for my own house I use 3/4 T & G CDX plywood, roof and floor. Plywood for walls too. LVL great stuff too...
Another framing video that should be titled "Amateur Hour" Learn how to frame if you're going to post an instructional video. Pick up a Simpson catalog so you can learn how to use their fasteners. You don't clip common rafters to the ridge with hip/valley brackets.
Just wonderful, I've been looking for "are trusses better than rafters?" for a while now, and I think this has helped. Have you heard people talk about - Beybigail Nonpareil Breakthrough - (do a search on google ) ? It is a great exclusive guide for discovering how to create better sheds and improve your woodworking without the headache. Ive heard some awesome things about it and my partner got excellent success with it.
Handy name switch. You cheapskates are not using plywood, instead you're using strand board and calling it plywood. OSB does not hold up when exposed to moisture like plywood. Thanks for the warning so your company can be avoided.
The meaningless elevator music in the background is really unnecessary and distracting, why do you play it? I would just like to listen to what you have to say, but will find another channel

Says collar ties need to be installed in the lower 1/3 of the rafter but are shown in the upper 1/3.

I learned something, thank you.
Collar ties have to be in the UPPER 1/3 or the rafter, not the lower as specified in the video.

@@christophermaidment4316 wrong
whats the song in the beginning? so smooth...
Why wouldn’t a ridge post be able to be used if over a window? Isn’t that what the girder beam is for?

What the name of the music playing SOOOO nice?

good video; I am new to this so every piece of instruction and information is critical ; please continue to produce great video; thanks,PATRICK.P

I was going to mention that. It hit me as soon as he said it. Also, "gutterboard" I've never heard of.
Good information. Thanks.

Gutter board? Otherwise known as a sub-fascia or fascia to most builders.
Better attach that post to the wall better -not just with toenails -unless you want that ridge to pull away from house.
C'mon fellas, stop using a ladder laid flat to walk on -- you guys are gonna get hurt. Get yourself an aluminum plank.
I noticed that too. Good way to get hurt.
Who picked this music?

Learn how to frame if you're going to post an instructional video. Pick up a Simpson catalog so you can learn how to use their fasteners. You don't clip common rafters to the ridge with hip/valley brackets.
He didn't do that and this roof isn't going anywhere. (So long as that girder is supported better than just bolted to the house studs, that is.)

How do you know the customer didn't opt for OSB instead of plywood in favor of the lower price point?
Ah yes, a know-it-all customer. I'm sure they love working jobs for you too.
