OK, I’m starting to think we hired the wrong contractor. Most of the new roof is finished in the front of the house, and upon first glance it looks nice. However when looking out the window from an upstairs dormer at the adjacent section of roof, it’s obvious to see that the courses are not straight. The house is l-shaped, roof is 12/12 pitch. Do pros assume they have enough experience and do not use a chalk line? Maybe I’m too picky, but every time I walk by that window I’ll see it. Is this something I should demand be corrected? Here’s a photo I took from the window: i209.photobucket.com/albums/bb21 … /roof1.jpg . Look just below and past the dormer and you can see it. Am I crazy, or this a sloppy job?
