For me, the ideas in th-cam.com/users/postUgkxy_pn55PK60wAV3X_C_RoLS_67mNonoCE Plans were a starting point for building different sheds . Ryan gives ideas that allow an individual to draw nicest conclusions into the design and building of his or her own shed.
Thank you for making this video. I’m brand new to roof rafters. Those roofer hangers really gave me a good idea of how to finish.
I played a drinking game with my buddies. We took a shot every time u said “uhm” 1:30 in and were obliterated 😂
Thank you that was a nice video I enjoyed it , thanks for posting it, people on here like arm chair carpenters ..easy to criticise when someone done all the work..most would be scared to do a video thinking of bad comments and so on .any way thanks again 👍🙏🏼👌🇬🇧
I think I would nail some rims on those 2X4 ceiling joists, to keep them from rolling over.
"If you have a little larger of a home".... That's a given.
🤣
Seems like the seat cut is DEEP I was under the impression that you didn't want more than a third of the rafter thickness as a seat cut? Thoughts?
agreed.
Doesn't matter too much, only thing past seat is overhang,
2/3 should be left
Did anyone else see at about 12:00 how loose & cracked the rafter was when he toe nailed it with the 2nd nail? Thing slid out 1/2" and he pulled it in by hand😂
Shoulda been a lesson on what not to do. Best use ties to avoid what he did..
Fantastic video
Thank you!
Thanks for the video. Very informative. Question.... what if you took two normal 2x6 joist hangers and hung them on the ridge upside down and nailed your rafters from the side. Crazy idea?
Good job .Compadre's 🇭🇳
Question ?
Rafter Tails you guys made a Horizontal CUT for the SOFFIT ?
is it NEEDED ? and what that thickness and not WIDER
The birds mouth is the more critical point of rafter attachment. I always mail the birds mouth first, then the ridge end.
Hi. I was wondering what the pitch is of your rafters? I need to determine how steep the roof should be in order to decide what type of tile to buy.
It looks like a 7/12 pitch but I could be wrong.
12/12
good luck shingling that roof without falling off
Decent schooling video, carpenters, TY.!Out in the field, be sure to utilize fall arrest safety system!!
A good video!
Can I use screws in those rafter hangers?
Do you connect the rafter to those horizontal boards across the ceiling?
]
How would you frame a cross gable roof?
Are those rafter hangers a single piece, double sided? For the left and right side rafters?
Same question
Can you use screws instead of nails?
Great job! I just want to know if these is a 45° roof. Thanks.
Yes .
I can't find anywhere where my following question is addressed: How do locate the rafters on the ridge board from left to right or right to left?? I'm not talking about layout, but the starting point. How do you ensure the rafters will be square with the sheathing that will cover them? So far, everyone just throws the ridgeboard up and nails rafters to it without explaining how to line them up square. How do you do it?
J P you do this by doing layout starting from the middle.
Your birds mouth cut is at least half the depth of the timber and shouldn’t be no more than a 1/3
nope
Philip J. Fry Mostly to prevent snow to my knowledge, if you live in a place that gets a lot of snow it gets heavy.
The support is on the base of the cut. Derp
@@JohnnyJr396 You are only taking into account the support of the rafter from the wall in, and in that you are correct. What you are not taking into account is the support of the rafter tail past the wall. THAT is where you are causing the stress point.
you get what you pay for
Not sure about cow boys! Hate to spoil people's fun, scribing on the outside is an excellent idea for people who don't like measurements! Thanks! Also, nice that you have parts so adjustments can be made if needed! Awesome!
Thank you for your video. Can I use screws on the rafters?
Screws break, nails bend.
New screws that are specifically designed for the shear loads. Older ones, no
this guys special
What size of nails do you use when toenailing? Any specific nail? Thanks
16D nails should be used during the roof framing process.
At 5:40 why not use a 16 D nail for that toe nail instead of the hanger nail to tac that rafter in place?
You're videos were very helpful one question tho. How did you know exactly where to put your ridge board so you can start hanging the common rafters
You use what's called the total rise to set the height of your ridge board. Total rise is the run, in feet, times the pitch number. If you have a 20 foot wide building, the run is 10 feet. If your slope is 12/12, you will have 10 X 12 = 120. Your height will be 120 inches from the height above plate to the theoretical peak.
The find the run u can use construction master pro to find it, measure the span(exterior wall to exterior wall) for example if you have 25 ft you subtract 1 inch 1/2 (ridgeboard) then divide the result by 2 and that will be where your ridgboard will land
@@Jay-tk7ib thank you for the math!
@@cindyjohnson5242 You're welcome. Just remember, this is the THEORETICAL height of your peak. The ridge board will be set slightly lower because you have to shorten your rafters by 1/2 the thickness of the ridge board. Also, add in the height above plate distance to bring the measurement all the way down to the wall plates if you're setting up center gable studs to sit the ridge board on.
@@Jay-tk7ib thank you!
Why didn’t you show the ceiling joist install?
Wish you would have added how you came to the height position of the ridge board.
why are the end joist different. one is short and one long?
Are there hangers available for the bottom or birds mouth cut?
yes there are!
JEEEEZ Have you guys not heard of half crowns 😜
How you determine ur height for ridge board? I see you have set in place
Pythagoras theorem
@@SWhite-hp5xq No. The height or rise can be whatever you want it to be. Whether you want a steep roof or not. The length of the rafters or the pitch is determined by the Pythagoreum theory
I think of little Christmas elf's every time he hammers. lol
Are you guys standing on 2x4 joists?? I guess it's braced underneath, but if no, 0^0 OMG OMG!!! CRAZY
USNVA dog dancing with man
sketchy as frig but it'll hold untill it doesnt
Are you going to have any vertical supporting boards for your rafters?
How do the hight of the Ridge determine in the first step? 11:31
cowboy boots on the roof??? tut tut
I just noticed that too 😂
Hell yeah cow boy boots on the roof. Must be to cold for flip flops
Um Um Um, why ?
Lol those are definitely proper PPE
Hello there. Guys, I am watching you over and over again most of the time when i have a problem. My problem is this. I am building porch cover with gable roof. I figured out measurements for comon rafter, birds mouth etc, but since porch gable roof is going to be connected with existing roof how do i cut and measure those small valley rafter. Thank you
NSM Construction .... Thank you guys very much for your kindness. I'll use your tip for valley jack rafter and help from other people videos. I saw all your videos so far and what I like about your videos is explanation of all detail possible . Excellent job . Please, make some videos about home edition , room , roof , etc. Keep doing what you doing.
common rafter run x 16.97 / 12. that will give your hip or valley rafter run. now to find the hip or valley rise is/ Valley rafter run x 8/16.97 , just remember that is center line of the stock so when you cut your beveled end thats to the center line of hip or valley rafter
Easiest way is to get your valley rafter/lay board installed depending on wether or not your existing roof is to be trimmed out or not and simply mark your rafter centres. Then measure them with a tape. If all is straight then you can work out a common difference in length and cut them all. The plumb cut on a cripple rafter or jack rafter ( cripple to a valley, jack to a hip) is the same as your common rafter and you can find your edge cut at the wall plate where the valley/hip meet the wall plate just take the angle between a parallel line with your common rafter up your hip or valley at the pitch of the roof not level.
Hope that is of some help.
Look up how to do a blind valley. It's pretty easy.
Instead of joist hanger nails can I use deck screws. I hate nailing
Uuum uuum uuum uuum good video.
11:55 if it was flush on the first nail, it was definitely out on the second lol
Should the birds mouth not be cut deeper than 1/3 into the rafters?
Very informative, knowledgeable young fella, needs to work on the umm tick, very distracting from his presentation.
Read your comment on the umm umm umm before seeing the whole video, couldn’t finish watching it! 😂
This is just superb, I've been looking for "ridge board for steep pitched roof" for a while now, and I think this has helped. You ever tried - Beybigail Nonpareil Breakthrough - (do a google search ) ? It is a good exclusive guide for discovering how to create better sheds and improve your woodworking without the normal expense. Ive heard some decent things about it and my brother in law got great results with it.
How high did you put the ridge beam based on your 12-12 pitch, don’t think you give this info as the video starts with ridge beam already in place
How is the the hight of Ridge.?
how was the height of the ridge board determined?
th-cam.com/video/fBxcx6YKz54/w-d-xo.html
notice the other guy is totally not paying attention and tries to walk passed the guy talking on a 2x8 platform suspended 8 ft off the ground
By the angle you want for the roof. That beam is also a bigger board than what you use to frame the walls with.
Probably could have spared a few more boards to walk on, why make it more more difficult than nessisary?
Your seat cut can't exceed 1/3 of the width of the rafter
Yeah that seat and heel looks WAY too big for that board with that pitch
toe nailing in the rafters at the bottom are too weak. They need metal brackets or wooden noggins added that can be through nailed into the grain of the wood.
Never ever ever cut your facia cut until you have set all your rafters,then you can pull a sting and cut.talk about wavy facia dude
If you've done a good job on everything else, you won't have a wavy facia.
They didn’t pre cut. The cut that is there is temporary. In a later video they snap a line and cut.
tailes always cut last, always!!
What is the best time to eat roti?
The Birds mouth cut is too deep ! Maximum allowable depth of a Birdsmouth cut is 1/3 of the overall depth of the Rafter . That is a universal rule worldwide .
Can you use wood glue instead of those nails…. Clamped over night of course.
Take a drink every time he says uhm.
Umm you were not kidding
Safety is not the priority here as in many of the videos. Maybe they should be using ladders and safety lines. Other than the safety issues, he has good knowledge of the trade for sure.
Take a shot every time he says “um”
The toe nailing of the bird's mouth wasn't done correctly. The nail was started too far from the top plate. It was about twice the distance it should have been. An inspector would probably fail it.
11:55 board moves after 2nd nail driven demonstrating neither held jack shit...."and okay!" lol.
you never describe the procedure to compensate for HAP,
Was thinking the same.
I think they just eye balled it .
Yeh thats deep seat
It's always a mistake to put your hangers on before your rafters.. the tops will be a little out of plane
Best view with playback speed 2x
From my research, birds mouth should be no more then 1/3 of board or it compromises strength. Your at 60+ %. Why?
Rookies trying out his hand, we all have to practice. Just couldn’t Watch much of it.
that birds mouth is not to code. it can only be 1/3 of the way into the rafter.
🤔 never seen anyone damn near cut the rafter in half cutting out a bird’s mouth
You moved the ridge beam up and down and did not check for plumb! If you lower it you will push the rafter away from the sheeting/wall, cmon man!
I was wondering something similar.
How do you know the ridge is level now , it appeared you just moved it around as you pleased. I never saw a level...
Not being an ass, I'm asking to learn.
Rafters certainly have to be level with one another. Otherwise, the sheathing will have waves up and down through it.
@@jamieemes4292
Nice boots
Your birdsmouth cut is way to deep😔
You know if you didn’t have the tail for the soffit and facia board it could be cut all the way across... the tail doesn’t support the roof cuz 🙄
no, but the birdmouth is designed to keep the walls from splaying outwards from snowload and such. Also, cutting them too deep will result in a weak birdsmouth so why would you make the effort but not do it right...inspector may just fail your project.
@@kenthelliker2112 not saying you're wrong about the size of the birdsmouth, but your explanation of why doesn't make sense. spreading forces are applied *by the rafter*. I always thought you wanted a good amount of wood left to resist bending stresses on the eave overhang.
Birds mouth 1/3 no more
Shouldn't be the bird mouth cut in only 1/3 that rafter? That your is like half ha ha, but I don't know I am not carpenter yet... I can see you are, then why is like that?
Good job. It would have been easier to build the whole gable wall on the ground first. would have saved you a lot of work up in the air. Not only that but it would have given you a pocket for yor Ridge nice and solid. Just a tip for you guys.
Jameson Cross 👌🏼👌🏼
Sometimes you dont have enough help to help raise the whole gable wall which could be heavy
@@nateg5915 that's like saying, sometimes you don't have enough help to lift a car when you are changing a tire.
aaaahm
Every sentence is um uh um sheesh
No edge protection and no underside protection. Good demonstration on how not to work on a roof. Biggest killer in the construction industry - working at height.
Not enough cursing and screaming. This is America, for the Love of flying fredrock. But seriously, Good vidi. Thanks, you old nailbender you
do not set a roof up like this. Someone will get hurt.
Uhmm
Dude you say Umm so much I couldn’t watch the whole video. I was going crazy.
Those toe nails look like they had about 1/8 of an inch grab. Humpty and dumpty up there building a roof.
There um was um something um that um kept um annoying um me um but um I'm um not um sure um what um it um was um
Parents would have done him a huge favour if they smacked him everytime he said umm as a child
3:37 isn't that bird mouth to big ....I am not an expertos, but bird mouth cut, should not go over 1/3 of the lenght of the rafter...this bird mouth on the video, is almost hitting half of the rafter. ..
Just saying
Uhm. Uhhhm.
Those seat cuts are too big
Screws, screws, screws!!! Toe nails are junk.. use screws.. you will be way happier and solid
Nails are better sometimes . Screws can snap , they have little shear strength in most types . I prefer nails for most applications .
Pro framer since 1978 .
@@NSMConstruction would deck screws be acceptable? i see a lot of people using those and impact drivers for construction and repair(even got to use theirs, them things are fun)
Nails destroy the wood it goes into, so the wood does not SPLIT as with screws. You would have to pre-drill ever spot so the wood doesn't split. Without pre-drilling, the screws weaken the wood, degrading the structural integrity and unless they are structural screws, they are not to code and have no shear strength like nails do but they also can not allow for movement from an earthquake like nails can.
Birds mouth way too deep
Is this your first roof you built? You look very unconfortable there and so the roof. Birds mouth will fail; too weak.
Nope
Uuuhm
Birds mouth cut is to much..no more then 2/3rds
UMM
"uuuuummmmmm"
Uuum
Ummm
Video says how to install a ridge board but starts off with it already up. How can you trust information from ppl who can’t even figure out what they are posting. #WasteOfTime
How many times are you gonna say UM UM UM UM
uhmm then uhmm
