Planning a 24x32 garage (I know people will say go bigger. I can’t based on lot size at my second property and zoning restrictions).
My question is; 24’ spread web 5/12 trusses, or 24’ common 4/12.
The price difference is a mere $15 a truss, at 15 trusses is only an extra $225+tax, and the gable ends are the same price.
The storage is obviously a plus, but how flimsy are these laterally at the peak? I will be building it myself, so if it’s that much of a pain to gain 300 sqft in lightweight attic storage (rated for a 25 lb live load on the bottom chord), I would be leaning towards the common trusses.
I live in central Minnesota, so a higher pitch would obviously aid in reducing snow accumulation, but there rarely is a winter where the roof doesn’t get raked at least once regardless.
Another thing is I’m shooting for 12 foot ceilings so I can have a 10 foot door. My in-laws have a camper they often ask to store on my property, and with deflated tires it would clear a 10 foot door. I also can’t go much higher than this (potentially may need to go shorter with the 5/12 roof adding an extra foot at the peak), due to zoning restrictions..
Headroom on overhead doors is typically a foot, but most the plans I’ve looked in my area call for a 3 ply 11 7/8 LVL header to span the 16 foot gap that’s required for a double door. An option would be use two doors, but I’m set on the width of the single door.
11 7/8” + 3” For the double top plate + 1.5” for the garage door horizontal jamb puts us at 16 3/8” headroom required, assuming the LVL is directly under the top plate. that would mean, with a 10 foot door, I’d need at the minimum 11’5 ceilings. 24 span at a 5/12 pitch puts the peak height at 16’5 roughly. That’s cutting it awfully close to the height dictating by my local building department, and that’s without slab height. Seeing as around here we typically have 6” slab on grade with thicker footings along the edges, especially in northern central MN, it’s pushing my allowable height considerably.
All of these play a factor in what trusses to select. Again; the cost of the truss is negligible compared to everything else that must be considered.
Any ideas?
