ridge cap shingles
 
I plan on installing a ridge vent in just the center of the roof the rest is just regular cap shingles. What is the correct way to transition from the cap shingles to the ridge vent without having a gap where water could get in?

Why just in the center of the roof? Are you sure that'll provide the correct intake-outtake ratio? Super important to create a balanced system, you know! Seems like it would just be easier to do the whole thing. This is a good article about that ratio: http://www.quarrix.com/help-support/...lanced-system/

Anyway, if you're positive about doing part of it, perhaps just installing the end caps will do it? Here's a video for ridge vent end cap installation: http://www.youtube.com/watch?v=qIa87qyT8FI

Right but how do you transition from just ridge caps to the ridge vent?

See if this helps. There's 3 or so caps under the ridge vent.

When I install a ridge vent like you describe, that doesn't go all the way I start my caps at the end of the roof and just continue up and over the vent. It helps if its warm out and you can gently bend the caps without creating much of a hump.
A few sunny days and they should lay flat.

If I go up and over won't there be a good size hump in the ridge and have a spot for water to enter?
