Jack, Roofrat & Happy Woofer...

Thanks for your replies to my recent posting- I have one follow-up question...
Is it better to use a closed/weaved valley (over membrane and galv flashing) or an "open" valleywith exposed flashing? I would think the layer of crisscrossed shingles provides extra protection - but I see alot of expensive homes with the exposed valley flashing. Opinions?

Thats up to your tastes..If you do choose and open metal valley you can get them to match the color of your shingles instead of the galvinized look which turns grey and sometimes begins to rust. I think the closed valley looks best not the weaved ones but thats up to you. Good luck

I prefer an open valley because the shingles in this area will fail/wear out quickest leading to an unsightly valley-heavy rain drain areas always wear out quicker.My preference is pre-painted galvanized metal.You won't have to worry about extra protecton from a weaved/closed valley as the gal metal will outlast the shingles.

Question

Now I'm confused. I thought a "Closed" and "Weaved" valley were the same thing, but based on Roofrat's reply it sounds like I was wrong. Is there a difference?

They basically are the same thing. Just forget it was brought up.
the difference would not matter to you. I really have no preference, however, if you think about it, a closed valley just gives you another layer of water protection. If you are using heavy laminates, then you would probably want an open valley, since these types of shingles will not lend themselves very well to a closed valley.
