They are Cambridge IKO dual black. And yes, I believe it's the variation of color. I have just never seen diagonal runs like that on a roof with architectural shingles. Especially dual black.
New Construction New Roof Really Odd
What is wrong with this roof? I am convinced something was done incorrectly. HELP!!! Why are there so many lines. This is a dual black architectural shingled roof.
