“The roof is inconsistent. I would be Interlock in having the Interlock salesman come out and take a look at it. Some of the roof is very uniform and some are random as far as the layout, so I am sure it has to do with who is installing what panels. The shingles on part of the roof are spaced every 12" and others are crowded together; it is not a very uniform look.”
