“So what is considered a steep roof?
This depends on who you are talking to. Some roofers consider any pitch over 6/12 to be steep. Others consider any pitch over 8/12 to be steep. Other only consider 10/12 and over to be steep.
Why is it more difficult roofing on steeper pitches ?
Depends on the type of roofing. On pitches 6/12 and steeper everything will slide if not secured. Pitches over 9/12 cannot be walked without boards attached to the roof deck to provide footing. The type of roofing you are using will determine the maximum pitch that can be walked. For instance a dry shake roof can be walked on a 9/12 pitch, but not a metal roof. Because you can walk on a 9/12 without slipping does not mean you should. In fact any pitch over 5/12 is dangerous.”To read the entire article click here.
