I am building a patio cover. It will tie into the existing single-story roof. The rafters will connect to existing rafters and travel to the edge of the patio (10 feet from the house).

The patio is 30 feet wide, 10 feet deep. I plan to have three 4x4 posts at the outer patio edge to support the rafters.

My question is, with a 15-foot span between posts, what size beam do I need to support the rafters and roof material?. This is the desert in Arizona. No ice or snow load.

Hi Mark,
I can give you the figures but I'll need the type of wood that you will be using. Fir, Cedar, Redwood,etc. The other thing is that you can probably get this info from your local building dept. and since they will need to inspect it later why not find out now exactly what they want you to use. Let me knwo one way or the other.....Mark Hammond
