Well, I do.
Forrest – not a roofer
In issue #314, Fine Homebuilding published an article titled “The End of Deep Energy Retrofits” by Rachel White of Byggmeister. The premise was that deep energy retrofits are not as…

I don't know, not crisp enough lines for me, but good water protection
Look ma, no jigs!!!
That usually is the criticism. I kind of like the undulationnessing.

Well feel free to weave then. Go and undulationness to your heart's content.

Can you say that here? Sounds......private....
Everything will be okay in the end. If it's not okay, it's not the end.
It has a pool.
Is this going to be a Mc Shed thread?

In my book there is nothing like standing seam copper. Wait till that woven valley gets full of leaves and twigs etc. How's it gonna look then?
Standing seam copper valley? Doesn't that slow the water down?
If it wasn’t for the Bank Payments,
Interest, Taxes, Wages, and Fuel Costs,
I wouldn’t have to charge you!!
I recommend over sized valleys (in width) the standing seam prevents the water from one side rushing into the other. And in most cases the metal valley will allow leaves, twigs and the like to wash down.
I use open valleys too, but I'm not sold on the standing seam. I've watched water on my 10/12 roof and its 6/12 dormer during very heavy rains, and have never seen it rush up the other side. The seam also makes detailing the top and bottom of the valley difficult.
I like them for effectiveness. I can't believe how many roofs in my area have the shingles cut on the wrong side of the valley (I mean on the opposite roof pitch so they'll channel the water under the shingles).... woven takes care of that by default.
For looks, though, I prefer a "California Cut". I like definition and straight lines.
Straight and narrow (minded)

Nicely done weave. It turns across the valley smoother then most I see! buic
Aesthetically, I like that look better.
Forrest,
I like the woven look, too. A lot of guys won't do them here. The reasons I hear sound fishy. I suspect that the real reason is that they don't want to take the care to do a good-looking job.
The roofers who did my pitched roof did woven valleys, and they look great 4 years on. 4:12 roof, 50-year architecturals in light blue. I can see one valley looking out the window from my shower.

"The reasons I hear sound fishy."I'm curious what reasons you hear that sound fishy. I don't like them either. Not here to pick on Forrest, but for my a woven is a last choice, with good reason.

Piffin,One reason that sounded fishy was from a roofer who told me that a tin valley would last longer than a woven valley. I am near the ocean...the other one...and have seen that exposed metal disintegrates rapidly. He was proposing straight galvanized valley tin.When I asked about a woven valley, this same guy said, "Oh no, those are no good, they fail at the bend. If you want to go without tin, a cut valley is best." The undercourse of a cut valley is bent, too. Why won't it fail at the bend?The roofer who did the work had no objections at all to woven, saying in essence, "If you like the way a woven valley looks, that will be fine. It is a perfectly good solution for a valley."Bill
my answer would be the same as the latter to a customer who asked for woven.I will agree that the reasoning of the guy who thought cut lapped was any better was faulty.When using a woven, I still run metal valley under it for the time when somebody does step in it and break it.I find it hard to weave valleys with steep roofs and cold temperatures, especially with archi shingles. I pretty much KNOW that a couple shingles will be fractured by the time the job is finished.

Piffin,I agree about the steep roofs and cold temperatures. Woven on a 12:12 seems like it would be dicey owing to the sharpness of the required bend. But it seldom reaches freezing here, and the roofs are lower pitch than further north, with the vast majority of roofs under 6:12.I did run I&W under the valleys before papering them. The I&W runs out onto the paper at the bottom of the valley that ends on a straight pitched roof, and continues to the gutter on the other valley. Compared with trying to walk an unbedded barrel tile roof, avoiding stepping in the woven valley of a comp roof is child's play!Bill
So do I .
What is more fun is when you have two different pitches , especially when one is steep, one shallow and you get to figure the correct weave pattern out.
>> figure the correct weave pattern out.If there is one that's close to an even ratio.I like the woven look.

A lpped or californiacut is the right choice for that situation - or a W valley

I will take that under advisement as a matter of opinion and taste.

My big fear with woven valleys is that I have yet to meet a homeowner who could resist walking on the valleys and ridges when they have to be on a roof. Fear seems to make these two areas exert some magnetic attraction. Holding onto vent stacks for support when butt sliding also seems to prove comforting.
Never really seen it done like that. I kinda like the basket weave effect.
Of course if I dont get some more work lined up i'll be basket weaving myself.
I like the weaved look too, but not on roofs.

"Welcome to Poo-ville, can I have your socks?Seriously Folks, I need a home for 3 lovers of your life.
Maybe a "Mullett " valley?

Yeah! Short on the front valley for bidness, long on the back valley to party.

they say admitting it is the first step
congratulations, you are on the road to recovery
