Valley Weaving


Hey guys, quick question. Does anyone know where to get a good tutorial on different ways of weaving in a valley. I would love to see something good online, but a book would be helpful as well. Thanks for any ideas!

Why do you want to do a weave valley? You should just do a closed cut valley. Here are some good book that describes how to create valleys:

I think it is easier and looks better. I also read that weaves are more prone to failures as well. You should check the bundle wrapper to see if a weave valley is acceptable for your shingles.

Say on a three tab roof... how is a properly weaved valley more prone to failure?

I also like the closed cut with the appropriate shingle systems. I am just wondering if you have seen something that I have not.

Valley Weaving


The only down side to a weave compared to a open or closed cut is that precipitation will run slower in the weaved valley than in a cut.
Either is acceptable if installed properly.

Looks wize, the cut valleys age better, the weaved valleys will stain and curl faster due to the slower run off.
