																	Zinc pitched roof. 
									
	
		
	
																	It comes in natural bright pre weathered and pigmented finishes. 
																	Because zinc roofing and cladding can perform well at pitches between 5 and 90 degrees it can be used all over the building envelope. 
																	You can construct a cold roof build up when using zinc but the absolute minimum pitch is 3 degrees preferably 5 degrees. 
																	Zinc begins its life on your roof with a nice dark gray. 
															
													
									
	
		
	
																	See more ideas about zinc roof roof architecture. 
																	A 3 degree roof pitch means just over 50mm in every metre so over 3 metres you only have 150mm to play with. 
																	Instead zinc like copper benefits from aging and weathering. 
																	Zinc is a metal that is non corrosive. 
															
													
									
	
		
	
																	Hope that s helpful simon. 
																	What is the minimum pitch for a zinc roof. 
																	This means it will not rust nor be adversely affected by weather. 
																	As a thin commonly 0 7mm material it can be shaped to follow curves and angles and is a perfect cladding material for your more unusual forms.
