The row overlap “reveal” manufacturers’ spec is 5-5/8”. Shingle face reveals are 4.5” prevalent throughout rows. Eave overlap is as much as 2”. Manufacturers spec is 1/2”-3/4”. I can see the black lines between misaligned rows (too small overlap) from the ground. The ridge vent is lifted in many locations. How bad is this? This is a recent new shingle installation.
