I’m building a lean to shed and I’m wandering if I can use 2x4s for the framing and roof. I was going to set the front 2x4 8feet on center and then on the sides span the 2x4 12 feet and put a 4x4 post and then stretch another 2x4 to reach my 24 feet long.

12 feet for a roof load, looks like you need a 2x8 for 24 on center. if you are saying its 8 feet wide and 24 long, you need a wall along the long side or if the top member is supporting the rafters, you should be doing a double 2x8 at least to support all of the rafters over a 12 foot opening.

where are you located? snow load? 2x4 for an 8 foot wall 24 oc is fine.

it sounds like you should draw us a picture so that we may help better.

I was thinking of for the roof attaching it to the 4x4x8 and using a 2x4x16 and centering it at 8 foot and then having a little over hang on each side.

The length is 24 feet. So placing the 2x4 every 2 feet. The sides I was going to attract one 12 foot 2x4 and then a second one to give me my 24 feet.

This is just to keep my two labs dry and their heated dog house. And also give us some place dry to play with them when it’s raining. We do get snow here in the pacific northwest but night in crazy. Well snowmageddon took us by storm year before last but usually it’s pretty mild here.

I sure as hell can't see what you're trying to do, and I'm a GC.
It looks your building 384 sqft of shed roof, but all the posts are the same length? 8' OC for 16' 2x4 rafters isn't going to work at all, unless you really hate those dogs and want them crushed. What sort of roofing are you putting on it? Don't say tile or my head will explode.

Ok sorry the drawing is not to perfect scale. Glad your a GC . It’s just a lean to shed. The 4x4 posts in the front would be 8 foot with the back 7 1/2 feet for a slight slope. Just wandering if I can use the 2x4 to make the roof. Using corrugated metal for the roof.

Thank you for your input I really appreciate it.

It’s 16 feet wide by 24 long. So I should use a 2x8 for the frame? Where should I support it for the 16 foot width and the 24 long ?

look at this picture. you need structure to hold the metal panels. posts every 8 feet would be fine. run 2x8's along each set of posts and then 2x6 24 in apart along the whole top of the structure. use hurricane clips at the attachment of the rafter and support beam. use the correct nails or screws made by simpson.

strip the top 24 in on center with 1x2 or 1x4 and attach the metal sheeting.
