The USSS sloped roof they where on was a steeper slope. Though they are very small from far away so I suppose that makes sense. -Treebeard.

*********************************
I am not a carpenter, but I did teach slope to 7th-graders. Through hands-on discovery and research, my students learned that the code for building a ramp is a 1:12 ratio of rise to run. Whatcha think is the approximate slope of this roof?!
That building is a 4/12 pitch or less.
Somewhere between 2.5 and 3 /12
