- www.homebuildi... Visit our website or watch more of our videos to learn more about home construction, roof framing and structural engineering. Here's another helpful video on the design and framing process to build larger buildings with conventional roof rafters instead of engineered roof trusses. With that said, you will need to check with local contractors and building authorities before building to make sure you can build large homes or garages on your property.

I recently purchased 30'w manufactured trusses for a 30x50 garage. Cost was 4,100 and took 6 weeks to arrive. Thanks for your content.
Those seem like prices from before the civil war:)
I was looking for information exactly like this thanks
Glad I could help
To save money vs. trusses I want to build my own roof system for my garage. The front gable side is 32’ across. 28’ deep. I want to use a 28’ LVL as a ridge board and 18’ 2x8s as rafters with a 4/12 pitch. Now this is where I struggle finding info on supporting the roof from here. I was going to do 16’ rafter ties halfway down with a 2x6. Is this fine or what else could I or should I add. PS. Rafters and ties are all going to be 24” O.C.
Your videos are all super helpful and informative! Thank you
You are so welcome!
I like the roof truss and rafter ties.
Thanks for your videos. I keep thinking if we were to do that angled rafter tie business on one of our jobs....we would have some very unhappy sheetrockers in the near future. (So far, our engineers have never spec'd things like this).
Help, Greg! I put in floor joists in my DIY 14x32 cabin and used 2x10 pressure treated wood. Now, most of the joists are bent, bowed and warped out of shape. I'm at the blocking stage and can't afford to replace the boards. One of them even warped into an S shape!
Email me a picture. You can get our email address at our website or contact the lumber company to see if they will provide you any help.
Could I build a pole barn this way? Would the studs need to be this close, especially if I used 6x6 or 8x8s?
I have an odd one. I have a detached garage 32 x 28. The joist run 28' long. They are starting to sag and I plan on insulating and drywalling the structure. Is there any way to clear span 32 foot on an existing structure?
I would think steel I beams or large glulam beams.
Doesn’t the rafter spacing get affected when you overlap them in order to meet these longer spans? I’m seeing that the bottom row will be offset 1.5”.
How do you account for this with roofing materials?
I have a one story house two bedroom my attic I do have an attic the height is 5 ft 5 in I would like to extend my attic at least to 8 ft how would I go about and doing that thank you
Awesome work
Thanks a lot 😊
that was really helpful. It also lets me use shorter boards
Great!
im making my 20 wide by 30 ft deep garage 40w x 30 deep im assuming its the same principle as you just expland however i dont want to keep the soon to be middle wall that is the outside of the current garage wall
I'm looking at building a home that will be 50'x72' that I will be building my self but can I do rafter/Trusses to span 50' ?
Check with a local roof truss manufacture.
very informative video! Thank you! If the support beam is not placed at the halfway point (on a longer/wider building), what is the recommended span to place the longer rafter? Towards the ridge or towards the wall?
Your spans are measured from walls or beam supports or ridge. In our video, one side of the roof would have three spans. One from the wall to the first beam, then next between first and second beam and then from the beam to the ridge.
@@gregvancom Thank you very much for the response! If the spans are not equal lengths, where would you place the longer rafter? Spanning from wall to first support beam or between the support beams or from beam to ridge? Thank you in advance!
Is the method of using spliced rafter-ties/ceiling--joists supported above from the rafter's ridge board (to span distances greater than conventional lumber is available in) compliant with the international building code? (Just asking as I can't find that it explicitly is?)
Good question and I will look into it. I don't remember any and usually lapped my connecting rafter ties with a four foot lap and about 10 - 16d nails.
@@gregvancom As best I can tell it's permitted to lap rafter-ties if secured with sufficient nailing similar to the requirement between the rafter tie and the rafter itself; but attaching said rafter-tie/ceiling-joist to anything else but a supporting beam (as opposed to a ridge-board) seems not to be permitted (except possibly if signed off by a structural PE). Overall I like the idea, as it should be a simple matter to add the worse-case ceiling load to the dead-load requirements of the rafter span, but this is not detailed in the code as best I can tell.
Hello. Great video, it answered the question I had. I was just wondering, I noticed that you didn't lap the end gable rafters, instead you show them butting together at the supports. Are they less important to supporting the weight of the roof, or are you sacrificing some support for a flat exterior face? Would you use a strap or plate to connect those together?
Yes, strap plates if you don't use collar ties. You can install ridge beam and lap rafters.
Il love your channel...
Can you make a gable roof using 2x6x16 size is 26ft wide x 12 deep
2x12 rafter can span at 20' ( 40 foot wide total) taking snow and dead loads and they don't need a ridge beam ( ridge board is ok) or other beams between the ridge and the wall. At 60' wide you may need the intermediate beams , but 40' wide , I think 2 x 12 are ok
Do the rafters have a bird mouth at each of the support beams?
Great video, can you explain on a future vid on how to to cut a brids mouth on rafters with a ridge beam?
See if this helps th-cam.com/video/I5jFPMdMBac/w-d-xo.html
Can you show a 54x60 building? Please and thanks
This is exactly my current garage, only it's 25' wide instead of 30ft. I want to go FROM THIS setup to a 2nd story add-on. I've watched your two story garage series but those seem to be from the ground up. Can ya add a second story on this thing without middle columns inside and put the stairs outside? I hope I don't get a lot of follow up comments to watch the garage videos even though I've watch almost all of em.....
I would think you could with larger floor trusses.
Have you done any videos addressing [engineered] roof trusses placed on top of existing ceiling joists/attic floor assembly? I've exhausted my capacity for searching effort and come up empty handed.
You probably can't find information, because the roof trusses need to be able to move freely up and down. A ceiling joist directly below, could prevent this.
Do you work with people for roof truss design?
No, it sounds like you should contact an roof truss manufacture in your area.
So this covers width.
Now lets say for example you want that 50 or 60 foot wide building to be 100 feet long how then do you duplicate this process?
Meaning best way to elongate those support beam structures to make a longer run for length of building.
I.E. indoor horse riding ring.
EXCELLENT !!!
Many thanks!!
Súper like.
How is this better than a truss?

Very helpful but man nobody is building a 30x12 garage or a 60x12 garage.
Are you saying you need a pole taking up the space inside your garage to support the LVL structural beam?
Show us the entire building roof design. Just not 12 feet of it!
LOL "no 10 is not the magic number"
Exactly!!!
To simple
