Shop construction help

I am planning to build a 22' X 24' garage to be used as a workshop. I prefer not to have any posts or uprights obstructing the work area. My problem is trying to dimension a center beam that would span 22' and support the ceiling joists as well as the roof. Snow is a factor as I live in Montreal. I looked at charts to calculate the required size but I am not an engineer and can't figure it out. Is the Beam idea old hat and perhaps I should look at a truss roof ?
If I went for a truss roof I am looking at a 24' span with 8' from ceiling to peak. I would also like to incorporate a storage space 8' wide X 4' high from front to back (22').
Any suggetsions would be appriciated. As I only visit this group on occasion areply by e-mail is prefered.
Thank you for your time

Truss. I have a friend that just built a shop. 28 feet wide and ?35-40? feet long. All drywalled inside. Has 11 foot ceilings and has a wall off center lengthwise but it isn't a bearing wall. He did almost all the work himself. But he was smart and got and had a cherry picker lift of the trusses which went very fast. Also used steel roofing.

Both actually. I have a beam supporting the second-floor shop, above which I have trusses.
Yes, you want a truss roof.
My local lumber yard was able to order trusses for me. The truss company provided me with the load specifications of the truss. This was the *one* thing that my local code enforcer specifically picky about. He was satisfied with the spec sheet provided by the truss company. No *other* architect required. Your local code may differ.
I think all I told them was the type of truss, roof pitch, span and overhang. They figured out the rest.
FWIW my trusses were built and shipped directly from Quebec. The driver spoke about 6 words of english. I'm about an hour south of you.
See your local lumber yard (not Reno Depot).

I think that what you want is a "scissors truss". If I've got my terminology correct, they can span the distance, yet provide plenty of interior ceiling height.

Yes, scissor truss does profide plenty of interior height. What it does not provide is a storage space (enclosed box above the ceiling) which is what I believe the OP is after.

I had some truss built for my 20x20 work shop and they offered a few designs that allowed for me to have some space the same as you are looking for. They were custom built me and only took a few weeks to build and arrive. The cost was not that much for 9 truss and two gable ends. They come with a signed engineering design sheet which is all the building inspector wants. Myself and a friend put them up but it was marginal. I would get at least three people or a crane to hang the size you are wanting. You can walk them in upside down and place them in position and then stand them up with a long pole. My rise was only 5 feet because of the low snow we get in N.C.

A steel "I" beam should do the trick. Or, you can sandwich a steel plate between 2x12s, fastened with bolts. You should get some advice from a local structural engineer to do some calculations. Steep roofs are more expensive, but last a lot longer in a rigorous climate.

As others have said, use trusses. Talk to your local truss seller or builder. They can custom design what they don't have as stock design, and you can get your support free span and your storage space too. Walt C

my pole-building, a 24'x24' footprint, was just completed. it has engineered i-beam joists ("clearspan") and the attic is completely floored with 3/4" plywood. i had considered an attic truss, however, the extra space afforded by the clearspan joists was worth the incremental cost.
a couple of things to consider are placing electrical and dust collection under the slab. i have just completed trenching for dc and electrical, since i know exactly where my ts, shaper, and dust collector will be located. now, i hope the weather holds out and and my concrete gets poured.....

I am just completing my 28'x46' (w/10' ceiling) shop. Purchased attic trusses to span the 28' width. I specified 2x6s for constructing the trusses so that the exposed overhanging rafters (2' overhang) matched my house. The two end trusses were spec'ed by the truss company to be gable ends (with ventilators provided) that made sheathing easy. Cost was about $100 per truss. I had about 5 relatives (including a strong son-in-law and 2 strong grandsons) help the day we put them up. Had them in place in about an hour. Put each in place sequentially working from one end to the other. Each was put in up-side-down and then rotated in place using a rope from up on top and one strong person pushing with a push stick from underneath. Used pre-made/purchased metal spacers (three between each pair of adjacent trusses) which made spacing/placement very simple and fast. Worked well for me; it beats cutting and placing rafters in place. Or steel beams.
