looking for some advice


Hi Forum members,
I am looking for advice on roof framing with regards to size of rafters and ridge board.
I am building a storage shed that will be 12 X 16 with 8 ft. sidewalls. The pitch will be a 5/12 so do I need 2 X 4 or 2 X 6 rafters? Should I use a 1 X or a 2 X for the ridge board?
Thanks for any help you can offer.

Larry

What is the length of the ridge board? 12' or 16'? What is the dead load of the roof decking, materials? You don't have your location posted, so no-one knows if snow load has to be calculated. Will there be rafter ties, or ceiling joists to tie the rafters together? You need to answer all of these questions.

What is the dead load of the roof decking, materials? I wish I had an answer for this part. I have no idea what the dead load is or how to figure it. Sorry

You don't have your location posted, so no-one knows if snow load has to be calculated. Omaha, Ne. As a worst case scenario, we might get 1 or 2 snows in the range of 7-12", but mostly our snow is in the lighter category and wind driven. I would not think snow on the roof would be a huge issue.

Will there be rafter ties, or ceiling joists to tie the rafters together? Ceiling joists.

You need to answer all of these questions. I hope this helps and thank you for your answers
I look forward to all comments.

You have to use 2x6 rafters: http://www.cityofomaha.org/planning/...SpanTables.pdf

You have to show the City where it is to be located but may not need a permit: http://www.cityofomaha.org/planning/...tePlanShed.pdf

2x8 ridge, build for snow. (One size larger than rafters).

Be safe, Gary

Thanks for your help. I was leaning towards the 2X6 rafters just because I thought they would provide a stronger roof. Wasn't sure though as to the width of the ridge board, so thanks for your input.

Why don't you just post this on the roofing forum? That's what it's for!

Maybe because I thought it was a general framing question.
