Ridge Cap Question using GAF Ridglass
 
I just finished shingling a roof for a shed. I am installing GAF Ridglass cap shingles (Z-tab?) over a Trimline ridge vent. Once I run the cap course, how do I install the final end cap shingle (prevailing wind side)? Nothing in the instructions tells me how to do this and I can't find anything on the internet. Thanks, in advance.

Cut a cap so only the bottom part is left and use 2, 3" roofing on each side. Cover the nails with silicone or roof caulking.

Joe,

Sorry about the question, but I'm an idiot. I'm guessing you mean cut off the end of the shingle that would normally be exposed and then just nail that flush at the end of the roof? Is that correct? Thanks, again.

You've already brought the caps from one end of the ridge to the other end, stopping about 2 feet from the end of ridge.
Cut off the exposed part, and install THE OTHER piece (I call it a Starter Cap) at the end of the roof. Then install a full cap on that one. Now you should have 2 caps facing opposite directions right? Now you take that exposed piece you cut off and install it over those two caps.
