Excellent job, I’m in the UK and always wondered how you did things like cathedral ceilings in the USA so know after watching your video it explains it all, you really really did a fantastic job and great explanation, thanks man !

The not so typical birds mouth rafter cut could split on the inside even though the rafters are oversized. I suggest driving one or two 4.5" to 6" Simpson truss screws in that area to avoid splitting. It looks like that you had to match the existing eaves, a reason for the deep birds-mouth cut. You did show a few things to shed light on my sections and details.

great job mate 👍 bit scary how many people in these comments are willing to trust an engineer that they arent paying and arent insured by!

planning on something similar myself... 30 foot span, 12 foot long steel flat bar, sandwiched by 2 timbers to stop it buckling (flitched beam). will be a pain to lift up!

Very helpful. Considering a cathedral ceiling for 16 feet of our home.

awesome work man!! loved the video and your detailed explanation!! keep up the great work!

[stuartmenzies]

I am retired carpenter...Love the idea of no joists And I kinda get your explanation of rafters bearing half the load and wall bearing half the weight vertically..Difference is for me is my span on walls is 18' and still would not use 12" joists, prob 2x8 would work for me on 16" ctrs

Awesome knowledge, skill and craftsmanship! Why did you inside bird mouth those rafters? It makes sense to me, I guess it's better than totally removing all the wood to let it sit flat? Are those rafters then notched? And not bird mouthed? Oh I see you did it for ceiling esthetics. Again, excellent foresight.

Great idea i think im going to use it on my coop

I have some questions. I'm adding a 14x16 addition off my gable end of existing house. Gonna do a cathedral...

[brucejones]

Looking at building a detached for a golf simulator room and I need lots of clearance on the ceiling. This looks like a great solution

[Reggiebob]

Thank you for posting this...this is exactly what I was looking for. My room addition is gonna be 16 wide by 20 ft long. Do you think I could use the double LVL like you did or would I need another one added. My outside walls are gonna be made of 2 x 6 and would that same bird mouth design work for me by adding an extra 1.5 Inches to rest on the 2x6 top plates? Also your header on the opposite end of the house ...is that LVL as well? Anyways thanks for the video!! ***

[fellspoint]

LVLs are great products but I was wondering if you have installed parallams in similar structural jobs ? Does one have an advantage over the other ? Either way, excellent work.

[alonsonevarez]

Great work bro!!, im doing an exterior porch with vaulted ceiling, but is 30’ ft long, what could i use for the ridge?, should i add a support in the middle?

[ralphriffle]

Could you show us your structural calculations for the roof please. Can you include tencile limits on your nails?

[vinicardoso]

Great video. I’ve a question. Can I cut some ceiling joists to have a bigger space as I’m doing a mezzanine’s/lift conversion in a 6m x 6m room?

[DetachedGarage]

I think I’ll need to do this same thing for the second floor of my garage.

[chrishouse]

Late to the party - any structural advantage to adding a small horizantal below the LVL at the top or just cosmetic? I'm working on plans presently but thought of adding a small section of flat to run electrical and add drop lighting (figured it'd be easier to mount on a narrow flat strip down the middle of the ceiling than a slope and doesn't limit the lighting choices as much as a slope). Logically it seems likek it would just tie the two sides rafters together and perhaps limit some sheer?

[garypillischafske]

Question on the Cathedral rafters. My entry door is dead center under the ridge. With a 12ft span can i use a header (size?) to hold up the ridge on that end?

[TELALITcellistandsinger]

Great framing! I do have a question - how will the drywall be installed in a perfect point if there’s the lvl beam in the middle and the rafters are going to it but not underneath it in a pointed shape? I’m asking because I have a similar ceiling and I’d like the drywall to be pointed with no flat part so I wanna make sure my framing is correct. Thanks! :)

Was this necessary to avoid collar ties? Tearing my roof off next year and was just going to do a ridge board. 8 pitch with a metal roof so snow load will be minimal
