Remove the section of the sketch that involved the gable end of the roof make sure the boundaries remain as closed loops.
													
																	Sloping roof in revit. 
									
	
		
	
																	A sloped roof is more capable of removing water from the building s exterior and can be an attractive alternative to the flat roof. 
																	Check variable material in the roof structure to create sloped insulation. 
																	The revit interface is a bit unclear about constructing a flat roof but no roof is truly flat and creating a flat roof in revit allows the designer to annotate the roof without having to deal with the issues associated with the modeled hips and valleys of a low slope roof. 
																	8 set variable material for sloped insulation. 
															
													
									
	
		
	
																	Creating a roof with different eave heights you can create a roof with slope defined lines at different. 
																	The insulation thickness must be at least as thick as the vertical slope else you will receive a warning. 
																	By default the whole roof will be sloped. 
																	To specify roof pitch select a slope defining boundary line click the numeric slope definition. 
															
													
									
	
		
	
																	In sketch mode select a roof boundary line that defines slope indicated by. 
																	You can use slope arrows to create slopes on a roof. 
																	Revit roof slope can seem complicated at first glance but by learning a few critical features you can create any roof shape you desire. 
																	By applying the defines slope property to lines of a roof boundary you can create different roof types including flat roofs gable roofs and hip roofs. 
															
													
									
	
		
	
																	How to model a sloped soffit for a gable roof in revit. 
																	On the properties palette select or clear defines roof slope. 
																	Select the original soffit and edit the sketch. 
																	Whether you want a double gable roof with 6 pyramid shaped dormers or a simple gambrel roof the basics remain the same. 
															
													
									
	
		
	
																	Use slope arrows to define slopes on a roof such as a 4 sided gable roof. 
																	For instructions see creating a sloped surface using a slope arrow. 
																	Want a sloped structure or a sloped insulation in your flat roof.
