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 slope a flat roof in revit. 
									
	
		
	
																	8 set variable material for sloped insulation. 
																	How do we create the slopes of a flat roof in revit. 
																	Several layers of waterproofing insulation finish etc. 
																	The insulation thickness must be at least as thick as the vertical slope else you will receive a warning. 
															
													
									
	
		
	
																	We cover creating the flat roof adding slopes to roof by using. 
																	This video covers how to create a flat roof in revit that contains slopes for roof drainage. 
																	How to adjust drainage slope of flat roof. 
																	Ok let s see what a flat roof is made of mostly. 
															
													
									
	
		
	
																	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. 
																	Check variable material in the roof structure to create sloped insulation. 
																	To specify roof pitch select a slope defining boundary line click the numeric slope definition. 
																	Get this revit file here. 
															
													
									
	
		
	
																	In sketch mode select a roof boundary line that defines slope indicated by. 
																	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 modelled hips and valleys of a low slope roof. 
																	On the properties palette select or clear defines roof slope. 
																	To create a sloped roof in revit modify the footprint sketch of the roof by selecting and specifying the slope defining edges of the roof. 
															
													
									
	
		
	
																	Want a sloped structure or a sloped insulation in your flat roof. 
																	A layaer of light weight celular concrete to give the slope to the roof. 
																	Yes i kept it simple for this i don t care if the roof is finished with gravel tiles or just the waterproofing.
