One layer off this house in Edgerton!  The pitch was quite steep, but we finished in about 4 1/2 days.  These are premium Duration shingles by Owens Corning with a limited lifetime warranty and 130 MPH wind rating.  The color is Colonial Slate, which is a refreshing change from the typical gray that many folks choose.   We installed ice guard on all eaves and valleys to help with snow and ice buildup in the winter.  Notice the low-profile ridge vent at the peak to help with attic air flow.  Looks great!  419-212-3200
