The ridge beam is holding the whole roof structure, it needs to be sized adequately, let me walk you through the installation of the ridge beam as well as a quick tutorial on how to size it the right way. I see if way too often, saggy ridges due to undersized ridge beams, don't be cheap, use the right beam and never worry again.
I am Tristan, I am building a 400 SF cabin at the back of my house. I plan on doing it all by myself. I plan on sharing this journey here on KZfaq where I will show you every step of the way, all the struggles I run into and everything I will learn from this experience. I will then rent the cabin as a short term rental in hope of covering most, if not, all my house mortgage (House Hacking). Follow me here as this will absolutely be one of a kind journey.

@@TheDIYCabinGuy That's why man invented the block and tackle pulley system. 1 man can lift a motor out of a car using one. I built a 4 season sun room on the back of my house and my retaining outer wall was 20 feet long and I had no-one to help me so I put blocks to stop it from going over and built a rig to use as a high fulcrum point to pull the wall up and into place and then secured it in place so I could level it and hoist the 2 outer walls in place to lock everything in square. There's always a way. it's just a question of figuring out how to do it. I could move a 2 ton stone block alone with nothing but round stones and levers.

I lifted beams bigger then that by myself with fairly minimal effort. How I accomplished it was building a A frame with a collar tie about 4 ft higher then the final height, installing a lag on d ring. From the d ring I hooked up a old block and tackle pulley attached it to beam and then hoisted it up. I like to have a tie off point ready so when I hit my height I tie load off so I can go up the ladder and slide it in the pocket.

That looked painful! I am a structural engineer and I have a feeling that the beam was a bit overdesigned. You could have used 12 psf for the DL and the 30 psf snow load that you used could've been reduced to about 21 psf (due to slope and other factors). There is a difference between ground snow load and roof snow load. A more economical beam could've ended up being (2) 1 3/4" x 11 7/8 LVLs. I am glad you were able to install it without any incident though!

absolutely. I mean, the rafters ARE important. And Collar ties important, but the ridge beam, if rafters are opposed to each other, is not anywhere near as important. I often make my rafters 4x or at least 3 by, and I always have collar ties every 4 feet or so, but I've never had a ridge beam anywhere near that size.

@grolfe3210 Жыл бұрын

Here in the UK the ridge beam is not used to take any of the load of the roof. The roof is made up of a triangle with two rafters and one joist, get this right and all the roof load is sitting on the walls the rafters are on. Typically these are factory made and just spaced on site with a 6x1 inch timber to hold it in place at the ridge. Generally we do not make a roof under about 30 degrees and it will be tiled with clay or cement tiles. It is only if we leave out the joists to make a loft room that a ridge beam may be used but even then not of that size.

@@eddied3246 Sure, a ridge can be designed as a beam to carry half the load of the rafters, but that is not the norm In most typical wood framed residential structures. This is why the term ridge board is a thing, they are usually just that - ridge boards - not ridge beams, because there are usually either ceiling joists or collar ties in an attic that help to carry the load of the roof and relieve all the outward forces it imposes on the top of the exterior walls. When the ridge doesn't have that help it needs to be designed as a ridge beam, a much more substantial structural member of the house frame.

The strop you used in making the hoist of the beam complete would have been helpful in all cases. Especially when you would have chosen to put a higher or proud chair for the beams, at the top of the construction. That would have helped significantly in getting these beams up. The excess of the chair can be easily cut to appropriate length when the beams are mounted properly. Why go through the inside, when your construction provides you two slides on which you can easily transport the beams upwards? Plus, some appropriate length scaffolding will also help, you may be tall, but are definitely working beyond your very own reach on that ladder you’re standing on. When we’re talking dangerous, well that’s something to take into account whilst building such a construction. Cheerio

You mean at the ends ? It’s to make the overhang. That’s what all builders in my area do. Then you can use a 2x6 for your sub fascia board and a 1x8 for your fascia. If I didn’t cut the beam which is 14” deep, I would need a 14” deep for my sun fascia and probably 18” for the fascia board which would not be feasible.

@ernieforrest7218 6 ай бұрын

Well first off, very few homes have the type of ceiling you are using in this home. Most homes using conventionally cut roof rafters will be using a ridge board, not a ridge beam. And they would also be using collar ties in order to connect the front and rear rafters together for additional strength. I am somewhat surprised you didnt build a scaffold for erecting those ridge beams rather than using just a ladder. And of coarse the scaffold could be used for installing all the rafters as well. But i get the impression that there were lots of things done for effect on this project, and not for expediency.

@@TheDIYCabinGuy Well, i havent always lived in Florida, and i am very familiar with mountainous regions of the country. Especially the eastern part of the country. For the most part, those building houses in those areas, many of which are used as vacation homes, are as concerned over cost as much as they are over design. And in many cases, even more concerned with cost. Vaulted ceilings as you well know can be achieved in different ways. And the Ridge beam design you chose to use is but one of them. The labor factor is a different situation completely. Yes, there are job sites that dont permit direct access to material deliveries. But then you can choose to use hand labor for moving material or choose to use machinery for doing it. And the cost factor should at least consider the time involved as well.

Hi. A doubt. You say that the wood formed from layers (LVL, I think you call it in the video) is more resistant than a single piece of wood? It seems surprisingly contradictory to me, when a priori, I would think that a single piece is more resistant than many smaller ones joined together, especially against the effect of humidity. In any case, I trust your knowledge. Good video man! Postscript: I hope the roof of my cabin does not fall on me 😂.

For footings, do you know at what height above grade it would be reasonable to skip the wood posts and lay beams directly on the concrete piers w/ something like Simpson PBS connectors? I'm doing a 12' x 16' project, where my original idea was to get all of the sonotubes on level so beams can be placed across them. I have some elevation change so one side of the structure can be as low as I want, say 6" above grade, but the other side may be something like 2' or more above grade in order to get level. After watching your video on bracing your posts, I began wondering if this is a bad idea... but having trouble finding good references.

You may want to account for "notch shear" when calculating your beam size. You cut the LVL pretty substantially. Notch shear is usually based on less than the depth of the beam at the bearing point.

As a draftsman, I stand behind my calculations, but I would recommend using an engineer on more complicated projects whether it is required or not. This project is a piece of cake to size the beams, headers, and footers, but as a project gets bigger and more complex there are many more factors involved. Most draftsman are just using shorthand and using sizing tables. A good engineer looks at the entire building as a system and can give much more accurate calculations.
