Good evening to all,
I am going to be installing a wood shingle roof soon and I was wondering how far back do I keep the shingles from the valley middle? I have ice and water shield down then a copper valley. The shingle exposure will be roughly 5″ to 5 1/2″.

good evening
what kind of pitch do you have and are there tall trees blowing in the wind
It has a 7 in 12 pitch and although there are large trees, none are very close and none overhang the building.
Pau;
hello jaeger
sorry about the delay
we use " w " valley metal in the valleys - hope your copper is about 20" wide w/ a braked inverted v for where the two roof planes meet
if your roof collects debris I'd go 2" from braked line - if verey little debris I like 1 1/2"
good idea to pull out wider ones for valleys so you have fewer joints right at the valley

That "w" is a bear to detail at the ridge and eave...I prefer a tapered line from about "=to exposure at the eave, to a narrower reveal at the ridge or hip"..tapered. Just a plain valley.
My contractor/boss/ buddy..might disagree with the taper part, but the W does not play in our jobs. Spheramid Enterprises Architectural Woodworks
HOW ABOUT THAT REZ GUY? UH HUH? ...He ain't Silesien I bet....wimp
John,I've seen the roofers do it like this drawing using a 2x4 or a piece of 5/4 x 3 as a guide.Joe Carola
I second the valley profile Framer showed in his post, and its method of attachment.
If it is a valley longer than about 10 feet, I like to see it smaller at top and larger at bottom, which means the shingle reveal changes from maybe 1-3/4" off the first bend of the W at top, to as much as 3-1/2" at bottom.
Longer the valley, wider the exposure. How wide's your valley metal? You don't want any nails penetrating the valley. Cleat it off as Framer showed. If you use 18" stock for your valley, the reveal will be less than if you use 24".
I don't buy into the wider at the bottom theory. Makes a hard job even harder. I use about 3" each side of center with 18" valley. 5" with 24".

The longest valley is approximately 13' long, then there are four dormers that have 4' valleys. My metal guy is making 18" "w" copper valleys. IAs you have suggested I have been setting aside the 11"+ shingles to use in the valleys. I spoke to my old boss who suggested 4"-5" from the valley center line. He also recommended the tapered valley but added it was more for looks than performance and with 4' long valley there wouldn't be enough taper to notice.
Thanks for all the input it has been helpful. I enjoy installing the cedar roof, the smell is great.

thank you Framer
have always been impressed w/ your illustrations
one day i hope to ascend from my remedial status and approach your facility w/ this computer medium
hopefully photos next step
