Is the angle the arrow is pointing to the pitch if this is the roof of a barn?

Answer 1

We cannot see your diagram. However, know that the pitch of a roof is the same as the slope of the roof.

So the pitch is not so much the angle as the distance the roof rises every 12 inches.

For example a roof with a pitch of 3 - 12 is a roof that rises three inches for every twelve inches across.

You can use the tangent function to find the angle of elevation from horizontal.

tan x = rise / run

For a 3 -12 pitched roof,

tan x = 3/12 or .25.

Angle x then is approx. 14 degrees.
