Quick - 1 day is all it took to finish the work Honest - no hidden or surprise charge Professional - Ken know what he is doing, check out my new roof ventilation The new skylight is amazing, my wife didn't even realize that it get installed and ask me why the crew left without install it. :) Only thing I might change of this whole process would be the timing. If only I have Ken's crew help me with my roof replacement few years earlier I won't have all the damaged plywood.
