Steeper slopes are ideal for areas that have higher snow loads and will also prevent the possibility of ponding water on the roof.
Porch roof 1 12.
Measure 12 inches from the bottom of the level and mark the spot on your house.
By matching the pitch of the gables we were still consistent with the roof.
This panel requires a minimum slope of 1 2 12.
This is the number needed for the pitch calculation.
Then measure from the spot created vertically to the roof.
If this is a porch on a trailer use corrugated sheet material can be found at lowes.
On this home the roof pitch is the same as that of the gables on the dormers.
The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.
A steep slope roof is one whose slope is greater than 3 12.
If a roof rises 1 in a length of 12 this is 1 12 roof pitch.
While the home s primary roof is a more steeply pitched hip roof the porch roof does not need to be the same pitch.
Comes in colors and an opaque color which would allow light into the area below.
1 12 roof pitch angle 4 76 degrees.
However you can only use this pitch with built up roofing or specialized synthetic roofing.
