Ridge Cap Shingle Installation Question


Are ridge cap shingles supposed to be installed across the entire length of the roof?

My contractor started them approximately a foot from the edges and they insist that's the way it's supposed to be. I looked at GAF's website and it looks like all of their pictures show the ridge caps from edge to edge.

Mine go all the way to the edge. Never seen it done like this before. Is it possible he ran out?

Ridge Cap Shingle Installation Question


I'd your looking and talking about ridge vents not ridge cap shingles.
Two differant things.
If it was cap shingles that were left short there would be a hole on the top of the roof.
Both ways will work, the caps are 4" long and are hard to cut so I just let them end where they will come out even on both ends using full pieces.

Ridge Cap Shingle Installation Question


Sorry, if I used the wrong wording. This is what I saw being done: they cut out the hole for the venting (not sure how long it was), then I saw a long piece of a black wire mesh, almost like a scouring pad, then they put the regular shingles over everything, then the half-piece of shingles which I thought were called ridge cap shingles on top. Those half-pieces of shingles that wrap over the ridge are the ones that stop about a foot from the edges.

I'm wondering if they ran short and if so, if I should insist they order more and finish the job the way it should be.

Ridge Cap Shingle Installation Question


#1 No way would I have used that style vent.
All my local shingle supplys and even the box stores in my area stopped selling it because just does not give enough venting, and done wrong it looks like a snake eatting a rat.
Cap shingles should have covered every inch of the vent!!!
Got a picture?

Another classic from a classic! Joes right on all counts, except that its a mongoose. That ridge vent don,t do squat except leak in a blowing rain. (Why do you think its named after a snake indigenous to Thailand?)

Ridge Cap Shingle Installation Question


He said the ridge cap shingles were installed along the entire length of the roof, but it looks flatter near the last approximately foot near the edges because the venting doesn't go all the way to the end. He agreed to stuff some venting under those areas to make it look more even.

Does this sound right?

Sounds pretty normal, ridge vent usually stops where the house stops and the overhang starts, but can be run to the edges for aesthetics.

With a picture we would know what your talking about.
He may have just layed the shingles over the ends and continued on to the ends of the roof instead of stopping on top of the vent. Which would look odd from the ground but should be fine.

Ridge Cap Shingle Installation Question


Here's a close-up picture of the roof. The pink dots show where the venting stops. I don't like the way it's raised along the peak and then tapers lower towards the ends. Most houses around here have the same thickness from end to end.

(we're getting new gutters tomorrow, so don't pay attention to the gutter that is pulled away from the house over the window)

Also, should the copper be showing in the front of the skylight?

Looks ok to be.
Yes that copper needs to be on top of the shingles, not under them at the bottom of the sky lights.

I believe the copper came attached to the skylight. I saw "copper" checked off on the box it came in.

Just have them run the ridge vent to the gable ends. The deck wont be cut, so it will not function, but it looks much better. The copper will turn brown in a while.

Ridge Cap Shingle Installation Question


Pipe collar flange is not my favorite type of install either by burying the bottom behind the shingles on the sides.

Whats up with the drip edge on the left side?
