Covered Porch beam code

user-7045733's picture

I can't find any info in the IRC for beam size and cantilever length for a porch roof. Can anyone help in aiding me in finding the information? 


Currently based off of the 2017 IRC deck beam span it says for 10 joist span 4x8 beam should be 7' on center I believe, don't quote me. I find this overkill because my old 2015 IRC states the Porch roof only needs to withstand 10 psf. 


Thanks yall. 

Are you confusing roof (post #216040, reply #1 of 1)

Are you confusing roof framing and floor framing?
