																	A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. 
																	7 12 roof pitch 30 angle 30 26 degrees details. 
																	Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. 
																	8 12 roof pitch 33 angle 33 69 degrees details 9 12 roof pitch 37 angle 36 37 degrees details. 
															
													
									
	
		
	
																	A roof of pitch 7 12 30 is manageable but caution should be taken. 
																	How roof pitch manifests itself in various roof types.

																	The pitch of both sides of the roof is generally the same although sometimes they may be pitched at different angles for aesthetic reasons. 
															
													
									
	
		
	
																	Also referred to as 7 12 roof slope 7 on 12 7 to 12 and 7 12 roof angle 7 12 roof.
