In this video, I'm gonna show you how to properly install a woven valley for your shingle roof.
Now, I gotta start with this:
personally, I hate woven valleys.
I think they just look ugly and messy.
However, they are an approved way of waterproofing your valley.
They do a good job waterproofing.
In my opinion, it just looks ugly.
I still wanna show you how to properly do it, and how the finished product does look.
Now, for a woven valley, we already have our starter shingle installed,
which you wanna make sure you have in place.
We're pretty much gonna start weaving these shingles in.
So we're gonna install our first piece right here.
And don't mind the used shingles, this is just for a tutorial.
One thing you wanna make sure is, you're going past
your valley centerline a minimum of 12 inches on your back end.
So right here is what you wanna see.
We've got 12 inches right here.
And now, what I would prefer actually to do is, prior to installing this piece right here,
I wanna install this, just so we pass this corner right here,
which is our vulnerable area.
So, we're actually gonna install this right here.
Now remember, you wanna come past your valley centerline.
So if this is your valley centerline,
you're coming 12 inches past that.
We wanna make sure we're not nailing it in the valley zone.
So I usually like to leave 8 to 10 inches from the valley centerline with no nails.
Alright.
Now, we're gonna install this shingle right here.
Again, valley centerline, 12 inches past the valley centerline and we're ready to install.
Pretty simple.
Again, just making sure we don't nail it right in the valley,
because this is where the primary water is gonna flow.
Now, as we're laying our shingles, the easy way to keep this 12-inch overlap
as well as make your job easier moving forward, is to leave this staggered pattern right here,
so that way when we're gonna continuing the roof, we've got our 5.5 inches here,
and that makes it easy for us installing the valley.
So, that's pretty much it.
You just continue that same pattern all the way up your roof.
Now, pretty much at this point right here, when you're close to about 12 to 16 inches
from your valley centerline all the way to this edge of the shingle,
you wanna restart with a full length
and pretty much restart this pattern, coming all the way up.
As I mentioned before, this is our least favorite type of valley installation.
I think it looks ugly and messy and we rarely use it on our roofs.
However, it is an approved method by Owens Corning and other shingle manufacturers,
so I figured I'll show you anyways, and show you why I don't like it.
