@@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. Ftr, I don't EVER want to do that but I know how to do it if I ever had to.

I love ridge beams. Especially peoples reaction when installing a huge gluelam beam. I always factor trees falling and tend to size up. Many haters on here but you did an awesome job.

[@TheDIYCabinGuy]

Thanks! Well I think a lot of people don’t understand the difference between a ridge beam and a ridge plate.

[@sandersonshomestead6818]

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.

[@TheDIYCabinGuy]

Nice !

[@oilscience9808]

Dude, that's about the most dangerous way to set a ridge beam. That's the way I like it! Thumbs up!

[@TheDIYCabinGuy]

😂😂😂 I mean we tried to do it somewhat safely.

[@tomlafferty4393]

It's worth clarifying that when you talk about a structural ridge beam in this case, you mean one that is to support a cathedral roof or shallow slopes. For a tied roof (or butressed walls or portal frame) the ridge beam wouldn't be supporting the roof loading but just providing stability to the load bearing rafters.

[@TheDIYCabinGuy]

Indeed, the difference a structural ridge beam and a ridge plate with a flat ceiling

[@newj9549]

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!

[@TheDIYCabinGuy]

You’re right, I didn’t reduce the snow load. Not being lazy could have saved me some backaches 😂

[@kondasixtytoo487]

multiply by .55 for reduction?

[@dallinweir]

Are you allowed to reduce the loads under prescriptive construction rules, or is that only allowed with an engineer's stamp.

@@dallinweir in Appendix C of the BCBC, the calculation is done at .55 for most residential buildings

[@paulkramer4176]

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]

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.

Sweet Jesus. I'm replacing the sagging ridge peak and rafters on my 40 year old garage this week. Before watching those video, but based on every other video I've seen, I was sort of counting on the job going smoothly as long as I had a camera rolling. Well, you just blew my safety net out of the water. At least to make up for it you helped me from using undersized ridge peak lumber. So..kinda thanks, I guess. ;)

[@TheDIYCabinGuy]

😂 you’re welcome. Good luck, check your numbers you might be able to get away with a 11 1/4” lvl. I went with 14” because theoretically I could get 3 ft of snow sitting on my roof. But most area without snow only have to use 20 PSF LL.

[@nlo114]

First beam was a bit of a struggle, but got there. Second beam; use the first beam as a lifting gantry It is a structural element, so would be able to support the second beam whilst lifting it into place.

[@bmwtravel1100]

even if you dont use better belay/pulley/rope system for lifting the load (and you should), please advise others to use some sort of safety rope loop around the hoisted lumber so that it cannot crash all the way to the ground and take out you and your ladder while lifting.

For a beam this heavy it would probably be easier to build it in situ. Build a temp support in the middle then lay out all the members and glue/nail them all together in-place.

[@TheDIYCabinGuy]

Could have worked well !

[@vincenthuying98]

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

[@TheDIYCabinGuy]

It could have worked indeed!

[@thegrantdanielsband]

Maybe it's just me but I like to put PL or limber lock glue in between the beams!!Makes me think scissor trusses are way easier :-)

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.

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.

Actually the ridge beam is full depth from support to support. Only notched at the overhang, watch the follow up episodes and you’ll see that the reduced height ridge beam Overhand doesn’t carry much of anything .

It’s a structural ridge beam, no ties needed

[@davidjessee7701]

Most builders don’t get it wrong . The purpose of the ridge beam is to be able to fasten the rafters one by one , then the rafters are placed opposing each other. And that is what creates the load structure… add collar ties and good

[@TheDIYCabinGuy]

See that’s the difference between a ridge plate and a ridge beam, you don’t need collar ties with a ridge beam.

Glad I could help 😂

[@deeeeeeps]

Don't undersize the beam... Then puts it over a door opening with a regular header. That needs to support all the weight of the roof. Hope they don't get snow.

[@TheDIYCabinGuy]

My header was checked, it can take it

[@dallinweir]

A relatively small header can take a lot of load over a small opening. Bigger openings require exponentially stronger headers.

[@lengarden1789]

Wouldn't nails have been been better than screws for assembling the two LVL pieces into one as a ridge beam? I thought nails had a better tensile strength than screws. Please correct me if I'm wrong.

[@TheDIYCabinGuy]

Good point but I think that screws do a better job at tying the plies together

[@davidjessee7701]

I love how “do it yourselvers “ grab the code book , over build everything then bash builders who have been doing this for years without fail… here you’ve added more weight to your walls without adding any real strength. Pretty presumptuous !!

[@TheDIYCabinGuy]

Trust me , the beam is sized appropriately for local snow and dead loads.

[@dallinweir]

Just because your building doesn't fall over, doesn't mean it was built correctly.

[@gregorymacneil2836]

Codes are put in place for public safety. They are written because failure can be reasonably anticipated or incidents of failure have already occurred. My advice is always to fully comply. I am not sure the installation method was the safest. Lot of load on that ladder.

[@puremichigan9318]

Im not sure if two lams were enough, much safer with four or six...

[@renurenovationsllc7780]

Code is the minimum you are legally ALLOWED to build. If you go minimum, it sags slightly in 4-5 years. I built my house to spec, but after years of seeing 2x6 spanning under 8’, and 2x8 on 16” center spanning under 12’ sagging in a few years, I now overbuild for my clients. After all there are some brands that have APA specs for 7/16 OSB that says 32” for roof, 16” for flooring, it seems pretty wildly under built, and saggy to me. Code typically defers to manufacture installation instructions, so good to go there. Over build everyone, wood gets weaker with humidity and humidity vapor intake/release over the years.

[@jcschwarb]

A structural engineer with a PE stamp can right size your beam and structure.

[@JS-ot4ki]

Member pitch on this should have been 0 at 7:24? Then roof pitch is 6/12 on the loads tab

[@TheDIYCabinGuy]

Nice catch! Yes I should have left the member pitch at 0. At the end of the day, I don’t think it affects the design thankfully.

[@JS-ot4ki]

@@TheDIYCabinGuy True, I'm sure it passes either way. By the way this was a great vid I've been having trouble confidently sizing a ridge beam and somehow ended up here after a lot of searching. 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.

[@TheDIYCabinGuy]

@@JS-ot4ki 2’ should be fine, I would have gone only with sonotubes if my highest point was only 2 feet.

[@angelaxinmeng]

both end cut off like 55%, will extremely reduce the strength of the beam

[@TheDIYCabinGuy]

It’s just for the small roof overhang. It’s common practice around here.

[@JerryXM991]

"Common Practice" doesn't mean it's correct. I'm not a carpenter nor an engineer but I know cutting half the beam at the end weakens the beam by half (at that end) that's a fact...

[@ralphriffle1126]

The building code is very clear. Design must be by the empirical method. No openings, show calculations.

You mean to span the whole length? I really wanted a piece of heavy timber for the look, it would have had to be massive to span the whole way and almost impossible for me to install due to the weight so I decided to go with multiple smaller sections.

It’s a wonder no one was hurt doing this, some kind of Scaffolding is needed for framing this roof. You are going to spend so much time and energy moving the only ladder back and forth and running up and down it just to put the rafters up. This project needs to take on a more professional approach, before someone hurt.,

[@TheDIYCabinGuy]

It would have been easier for sure. Having said that, framing is all done and nobody got hurt 😃

I would build a cat walk. It would have been so much easier. And a lot safer. And make it easier to put up your rafters.

That ridge board is ridiculously over sized a smaller size will not sag if the rafters are reasonably spaced.

See that’s the difference between a ridge board and a ridge beam. Mine is a ridge beam and needs to be sized appropriately

[@davidfifth6109]

I think the wording in the video is confusing. As you mention, this is a ridge board application but with a "beam" sized to support the weight. I'm not an engineer, but I think this application might still warrant "some" collar ties to offset the rafters pushing out the walls given they are not sitting on top of a beam, but attached to the side.

[@TheDIYCabinGuy]

@@davidfifth6109 not needed because this is a structural ridge beam and not a ridge plate

[@davidfifth6109]

@@TheDIYCabinGuy while I understand your terms, by placing the rafters adjacent to the LVL it is a "board" not a "beam" which supports from below. It's a novel application of a ridge beam/board. FWIW your choice when using the website calculator clearly was a beam underneath the rafters. Again, you've got a novel idea, a hybrid that maybe a bit confusing per many comments. With respect, I'm not suggesting it's wrong or will fail, again reading the comments, I believe it's confusing calling this application a "beam".
