California Open Valley


Hello all, I'm looking for some direction on how to lay starter strip with a open California valley. I'm guessing I stop it and cut the angle of the first parellel shingle to the valley? I'm also wondering how to cut the top of the flashing at the saddle.

Thanks in advice for the responses.

I haven't done that type of valley. Just make sure none of your shingles come to a point. The point will catch plenty of water and send it under the roof and into the house.

Run your starter strip 'over the metal' to the angle cut, then the first course, etc.

At the top of the valley your metal will be cut roughly and inch or so above the top, than make a couple/a few release cuts to allow the metal to rap over.
Than run your ridge caps across it 'after shingling' making sure to keep your fasteners away from the valley's center line.

Slyfox, thanks for the response. I'm guessing I have to cement the starter strip on the metal flashing to mimic the mastic on the parellel shingles?
