Hi Jeff, you might want to contact ELK customer service. Depending on which style you have they might not recommend a woven valley. I bet that they can shoot you the instructions via email. Weaving a valley is an art and if done wrong it will leak.

I'm surprised they did not fall off the roof being that drunk.

Well It's been a year know , no leaks .

To answer, the higher or steeper slope should be overlapping the bottom.

JP-- that was a great reply!!

Glad to have helped. But I must agree with Jerry & Richard, the valley is not woven correctly from what I can tell in the pictures. A while back somebody posted a picture of a correctly woven valley, it would be great to find that picture and look at the difference in it and yours.

With that heavy of a shingle it might have been better to have gone with a cut valley. Weaving dimensional shingles like you have is very difficult.

I found the picture of the valley. It is from Roger Robinson's company in CA, Star Inspections. Now this is a 3 tab shingle but the valley part should look the same.

Nope.

You get to play in the big game.

I only get to come in and show you where you are wrong ... in front of the judge.

If you come to learn, or help teach, do so. If you come to criticize ... we can all play that game together, and you will lose.

Besides, now that you are playing 'that' game ... it is not "Weaved valley", it is "woven valley".

And "monday" is "Monday".

Woven valley = Sure Leak. Bad choice in snow country for sure, and I believe equally bad everywhere.

Having done roofing for 35 Years, I have never found one that I removed for reroofing that had not leaked.

Bad choice, bad choice, bad choice.

When you have two diffrent pitches always start with the low pitch side first. When the shingles are woven they will cross each other in the center of the valley. The "cross" or where they overlap and kind of looks like a "X" will drift out of the center of the valley after a few courses and then you have to double the low side before bringing the high side over to bring that back to center.
