I'm in the planning stages of my new porch roof. It'll be a hip roof with a front-facing gable in the center. I'm working out the sizes and proportions. Are there any standards that I should use or be aware of when designing a roof? Such as:
A typcial height (from floor to ceiling, or post height)?
A distance that the roof should overhang the porch floor?
Any of this type of information would be extremely helpful to me. Thanks!

You are either going to have a hip roof, or you are going to have a gable. You can't have both -- the hip eliminates the gable, and the gable eliminates the hip. (I'm assuming that you will be tying the roof perpendicular into the existing roof -- one ridge line runs north and south, the other runs east and west. How many sides of the new roof can you put rain gutters on? With a gable, the answer will be 2. With a hip, the answer will be 3.)
The pitch of the new roof will be determined by the width of the addition and keeping the ridge line of the addition at or below the ridge line of the existing roof. Yes, you COULD have the ridge of the addition above the existing ridge, but that will mean having a little gable at the top to make up the difference.
Generally, you will use the same pitch on the addition as the house has on it.

Maybe I didn't explain that right, or I used the wrong terminology. It'll be a hip roof, with gutters on three sides, with a small gable in the middle, over the steps. Is that named differently?

Dormer -- now I understand!!
Not a problem -- It just takes a thousand words to ACCURATELY describe things so that everybody gets on the same page.
The rest of what I said applies. You GENERALLY want to use the same pitch on the addition as exists on the present roof. The width of the addition will really be what determines the best pitch to use, as well as the type of roofing that you will be using. If you are in an area that gets snow, you will want a fairly steep pitch. But in that case, you should already have that on the existing roof.

Is it called a dormer? Here's a picture of what I want (I know it's not a hip, but it has the gable/dormer thing in the center):

I'm in PA, so I'm getting snow. The roof that is there now has virtually NO pitch--it's almost flat. It's nasty, and I can't wait to get rid of it.
Thanks for the comments... I hadn't thought about keeping the pitch close to the main roof's pitch. Once I get things laid out I might post a sketch of my plan here so you guys can give me some feedback on it. Thanks for the help!
