5 20 for light snow.
Thus a 4 12 pitch would be a 33 slope.
Another widely used method is to follow the house s roof pitch on one side building the ridge off center then sloping down more drastically on the shorter side which will be closer to the house.
A 4 12 pitch is around 18 5 degrees but not exactly.
If you are using ag metal 29 gauge 3 wide anything less than 2 12 is a no no especially if there are valleys etc.

Some builders even choose to match it directly especially if the shed s roof is attached to the house on the high side and just one simple span pitch.
For dead loads you are correct.
You can also divide the rise over run multiply by 100 and get a percentage.
As i design roofs today in ski resort areas i use one of the above types of roofs and plan to keep the snow on.
