Asphalt shingling / not align properly
Hello friends , I consider myself pretty handy ,from autos to recently a bit of construction. I have built a tool shed (8ft x 10ft) and a work shop (16ft x 20ft) both constructions turned out to be quite handsome pieces of work, except for the shingles on the roof. Here is my question: In applying asphalt shingles is there some foolproof way or trick of the trade in keeping a consistent brick pattern ? Because when I am on the roof , I am centering the cut line of the shingle I am laying over one whole segment of the shingle previously laid and when I am all done, the pattern still seems to go crooked. I was thinking maybe there might be some kind of tool or technique that I need to know about. ANY help would be appreciated. :confused: :confused:
