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