Minimum slope for tiled roof over porch?

Question

is there a minimum slope for concrete tiled roofs over a porch? i know it's 3/12 on a house, but what about a porch?

Answer 1

Because it's absolutely the same number everywhere on Earth. (bangs head against wall)

Answer 2

answer one is right, and a pretty funny way of stating it.  it's the same, the water has to run off, or it will seep under, and the angle allowance is the same in all roofing situations.

Answer 3

I would never build less than a 3/12 pitch, due to water issues.  If you are in a snowy area, you will want to make sure that your roof is steep enough to allow the melting snow roll off.  Good luck.
