View Full Version : Low Slope Roofs
2004-04-12, 11:08 PM
Hey all, I had a few extra minutes today, so I thought I'd mess with making a low slope ("flat") roof system with tapered insulation. In a previous post we did this with void families leading to a drain. When thinking about it more, I thought it would be smarter to do it with solids on top of a roof. Soo.....
Here is a roof-based family with tapered insulation, protective board, and a membrane. It is designed to go on top of a roof containing just the substrate components. i.e. your roof would just contain metal deck perhaps...
Any comments, suggestions?

Nice! Better than the subtractive method, in my opinion. Your method is thinking more along the line of 'how would you build it.' The subtractive method seems to be more on the line of 'how should we model this', but you would never actaully construct a roof then carve part of it away for drainage.

Here's one with the same Idea that turns a corner....

Steve, when I open any of the two families you posted I just get a load of text on the screen, is this just me. (see attached screen shot) I would like to see your roof based family if poss.

hmmm... curious. It looks like it is opening in explorer. Can you right click and download the file so it will open in Revit?
Has anyone else had a problem?
attached are images of what it's supposed to look like

Hey all, was thinking about this more, and I decided that it would be more effective to simply have a single triangle insulation cricket that could be rotated, adjusted, placed, etc. multiple times. This allows a lot more configurations than the square and l shaped ones I posted before with just one family. Also allows for interior drains as well as scuppers.
I also included tags for the +/- elevations of each corner based on a starting elevation (0'-0" usually) and a slope arrow. All can be adjusted independently or turned off.
Anyway, thought I would share. Would welcome any comments or questions!
p.s. I have one with only the back edge and the nose adjustable, not all 3 point independently. If anyone wants that one let me know and I'd be happy to post it.

Steve & All -
Thank you for the 3 point adjustable cricket. extremely helpful. I have been trying to modify the family just a bit so that when viewed in plan, the top surface of the cricket displays as diagonal cross hatched (see attached for the look i am after) - The top surface in the cricket family seems to be 'Roofing - EPDM Membrane'. i have tried modifying the surface settings for this material inside the family file... it seems these settings can change the cut properties but not the surface properties.
Also - the elevation annotations are not visible when i place the family ?
Any insight you (all) can provide would be appreciated.
