Having a new home built and selected a black roof. I noticed that some spots are different colored. Most noticeably on the top of garage and top of main roof. Top of the garage looks like an upright rectangle. Top of house looks like 2 large Diaganol sections. I did go 2 days ago and it looked like everything was uniform. Today, the patches are back.
Sales lady said its normal and will disappear as the roof “weathers”
Attached are some pics. Roof is about 1 week old.
