That means the roof doesn t shed water as easily as steeper roofs which is why choosing the right type of roofing material is so important.
													
																	2 12 slope roof. 
									
	
		
	
																	Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. 
																	The exact roof slope in degrees is given by the arctangent. 
																	Low pitched roofs have the pitch below 4 12 33 3. 
																	To obtain an accurate roof pitch measurement properly measure the rise and run. 
															
													
									
	
		
	
																	A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. 
																	Definitions vary on when a roof is considered pitched. 
																	Conventional roofs have the pitch ranging from 4 12 to 9 12 33 3 to 75. 
																	In degrees 10 2 in 12 or 1 in 6 is considered a minimum. 
															
													
									
	
		
	
																	For roofs that will experience heavy snow or wind and will span the same distance use 2 6 rafters. 
																	Then you ll be able to measure slope from an unfinished attic space under the roof. 
																	Simply put it s a shallow roof. 
																	Asphalt shingles continue to be the most widely installed roof covering option in north america. 
															
													
									
	
		
	
																	For roofs that won t experience heavy snow loads a gable roof can span up to 22 with 2 4 rafters. 
																	Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level. 
																	The table below shows common roof pitches and the equivalent grade degrees and radians for each. 
																	You can use either 2 6 or 2 4 rafters for roofs with a 3 12 pitch or greater but it depends on the overall size of your shed. 
															
													
									
	
		
	
																	I ve been reading and reading but haven t found a good answer. 
																	The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. 
																	They provide excellent weather resistance great value and now more than ever a tremendous range of beautiful designs and color blends. 
																	Generally these roofs have a pitch from 1 2 12 to 2 12 from 4 2 to 16 7. 
															
													
									
	
		
	
																	A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. 
																	Most roof s have a pitch in the 4 12 to 9 12 range. 
																	This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 
																	They are the easiest ones to construct and. 
															
													
									
	
		
	
																	The short simple answer is 2 12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles.
