Ridge Vent Instalation Question

I am getting ready to finish the top section of a gambrel type roof on my shed. I want to place a ridge vent across the top peak. All the pictures I see of this type vent system shows the vent ending short of the edge of the roof, and the sheeting being cut out where the vent will cover. Can I just start laying the top sheeting 3" down from the peak and place the vent all the way to the edge of the roof? This would let me use 3" less plywood on each side of the roof sheeting, not have to cut it out after nailing it all down. Is there a reason to not run the vent all the way over to the edge of the roof line? Will it leak on the ends if installed this way? Does the roof vent sections come with the ends capped off so they will not leak from the ends? Any information is appreciated. I will complete covering the top of the shed roof this week. The shed is 12X20 Thanks in advance C Cole

I think the ridge vent stops before the ends of the ridge because asthetically, what you'd end up with would look a little funky.
As long as you cap the ridge along it's entirety, there's no reason not to continue it to the end.

If you use the honeycomb type ridge vents you can run them right the edge of the roof and they will not leak. There in no special endcap just shouldered nails so you dont drive them in too far. Home Depot sells this type of vent. I have noticed a lot of new construction going to the edge of the roof with the vent.

3" down on each side? You're scaring me. That is way too much.

He may be talking 3" total, or 1.5" on each side. Last ridge vent I installed recommended a 1.5" opening on each side.

Yes, generally the vent space is an inch on both sides, and you don't want to limit that by restricting the opening space from the roof peak.

Thanks to everyone for the replies, I was given two links for ridge vents, one from Skil Tools and the other from Owens-Corning. Both say I can run them to the edge and I am to have a 1 1/2" opening at the peak with trusses. C Cole
