" However, in general terms, low slope roofs (commercial roofs) are those below 2/12 or 3/12 while steep slope roofing would consists of roof pitches above either 2/12 or 3/12 and higher."

Flat Roof: 2:12
Low Slope: 2:12-4:12
Conventional Slope Roof: 4:12-9:12
Higher Slopes: 9:12 - 20:12
Steep Slope: 21:12 and higher

"Steep slope roofing also generally lasts longer than low slope roofing because the systems shed water much more efficiently and generally are subject to less direct U/V activity." - Certainteed
 
Walls are completely different, there are houses aroung here that still have stuff that looks like msr roll roofing with a pattern on the walls. It was put up at least 60 years ago. The houses have probably 12 inch eave overhangs. I'm not saying it's in great condition, but it's still on the wall and still has granules.
 
Landmark installation, goo the edges down.

STEEP SLOPE
Use six nails and four spots of asphalt roofing cement for every full
laminated shingle. See below. Asphalt roofing cement should meet
ASTM D 4586 Type II. Apply 1" spots of asphalt roofing cement under
each corner and at about 12" to 13" in from each edg

I was gonna get around to mentioning Insul-Brick eventually.
 
Many homes out here just have a 1/4" to the foot fall. They usually get TPO. very common in areas where ocean veiws are important.

The storage building complex I am presently building has 1/4:12 pitch on the buildings. Being these buildings are "plug and play" kits, there isn't room for sloppy concrete work. We've needed to fur out whole roof structures in order to eliminate the pond that got transferred to the roof from a poor concrete pour.
