Photo needed: California cut valley

I need a reasonably high resolution photograph of a California cut valley for the roof course. We’ll credit the donor. Anybody?

I emailed one to you. Let me know if that’s what you’re looking for. I can get a better image if needed.

-Tim

Thanks Tim!

Post the Pic. i do not know what a Cali Valley looks like.

In the California cut valley, the top layer of shingles is not cut.
Instead, it stops just short of the centerline of the valley, which has a row of shingles installed end to end along the valley, with the edge of these valley shingles terminating in the center of the valley, as you use here.

I’ve never seen this in CO or CA (southern) but Tim says they’re common in his neck of the woods (TX).
I just called tech support at GAF/ELK and Certainteed and neither one of them recommend it. Certainteed had never heard of it and I think mistook my question for a cut valley.

See GAF/ELK Steep slope Technical Point #136-07, I can’t seem to post the link.

How about this one Kenton?

WTF is that??? Oh my. :shock::smiley:

I consider the California cut valley installation method a defect up here in snow country.

Oh yeah! Do you have that in fairly high resolution, Michael?

Yes I do, I will email it to you. @nachitv account.

Brian, FYI I deferred to a roofer for this and other irregularities on this particular roof, although no leaks found.

It is quite commen here in San Diego, probably the most common right after tiles.

They’re ALL the rage here! ;D

Every one of these was new construction by a national builder… and the results…

Hey Ken up here in N. CA I see them all the time, let me know if you still need some pics, I may have them for you. With over 5,000 roof inspections I may have a few…lol…

my 2 cents every home with them should be called…thats my thinking…after roofing for 15 years I have seen my fair share of these valleys leaking…

Like Larry said, not used in Snow Country.

Looks like I have California valleys covered now Brian, thank you, but I’m looking for pictures of tobacco staining and anything showing visual issues like racking or mixing shingle lots.

Since this is all high definition video, 640x480, which is what a lot of us shoot in, is too low in resolution.

I’ve been looking at posts by roofers and like you, most don’t seem to trust Cut California valleys. And they look like they’d install fairly quickly too, so if they’re fast to install, but roofers don’t like them… that says quite a bit against them.

Ill take alook, a while back we installed a few roofs and had issues with the lots having color issues see what I can find.
