Roof pitch for a patio cover.
This patio cover plan example uses galvanized metal as the roofing material.
That means that the patio must slope away from your house at least 1 4 inch per foot for at least the first 10 feet from the house exterior.
To calculate your overall roof rise or fall multiply the roof slope by the entire distance from the home to the center of the beam line see the examples below.
This meant the patio cover could start at the edge of the house s roof at a height of eight feet and slope down to seven feet leaving a clearance of more than six and a half feet between the lowest part of the frame s headers and the ground at its outer edge.
All hardscape within 10 feet of a building must slope away from the building with a minimum slope of 2 percent.

Pergola lattice covers do not have a minimum pitch they can be flat however the maximum slope is 1 per foot.
You need to remove any vegetation soft soil and rocks before you begin.
So you would need to pick the right option as most regular standing seam metal roofs will require a roof pitch of 2 12 or even 3 12 at a minimum.
Using corrugated metal also allows me to reduce the degree of slope or roof pitch needed to a mere 10 percent or a 1 to 10 pitch.

You could also opt for a pvc flat roofing membrane.
There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 12.
