I will try to start on my 12x20 garage project this spring or summer. But I am wondering should build a 4/12 gable roof or a 4/12 hip roof to match my parents house. This will be my first framing project since I left trade school in three years.

Which ever matches the house...

Can you scale it up a bit, 12x20 is pretty small, and the cost/sf isn't that much to go bigger

The blueprints is a 12x20 garage. The building official wont mind if I change the roof design. Is a hip roof hard to do? Its been awhile since I frame one.

Shouldn't be too hard CJ.

Still have your books from school?
on't worry, we can help you if you get stuck.

Easy. And that size would be about as simple as you could do.

Yes I still have the books. The plan call for 2x4's for rafters? Will 2x4's pass code?

 

[bdavis466]

No way 2x4's would pass here...unless you mean 2x4 trusses?

I agree with the previous post about making the garage bigger. I just finished mine, 22x48 and now wish I would have doubled the size of it. It won't cost much more to make it a little larger.

For as short a span on RR as you are talking about then the code (IRC 2012) will allow for 2x4 DF #2 or better on 24" centers.
Dead load = 10 or 20# etc.

Do not use 2by4. 24 on center. !!! Bad idea. If you stick frame. Witch you should ...go 16" on center 2by6 or better. I would use 2by8.

 

[Smithanator]

Hip roof like that pretty simple but def more involved than straight gable roof.

 

[CJ21]

I live in Alabama so we don't have problems with snow loads.

 

[TimelessQuality]

Get a price on a truss package... You'll probably be surprised how reasonable it can be

 

[Smithanator]

Even if 2by 4s would pass. Witch they wouldn't. You can't even get a birds mouth cut on them

 

[Smithanator]

It will be substantial cheaper to stick build and not buy trusses. Especially since you are doing work.

 

[CJ21]

Will 2x6's then. It will be cheaper to stick build, and plus its good practice.

 

[Smithanator]

Yes

 

[Smithanator]

If you go 2ft on center ,then you have to put h clips on roof sheathing pita. It makes no sense in my book not to stack frame over your studs 16" on center and buy a couple extra 2by6s. Plus much better frame job. Thumbs up . I would be happy to help you with any ?s

 

[Smithanator]

I did nothing but cut in roofs on new houses I built for 10 yrs

 

[Smithanator]

If you have a I phone get power 1ce construction calculator . It will cost you $5 and tell you all you need to know. Type in span and voila

 

[CJ21]

I just was taught to frame rafters 2 ft on center.
