Peter in Markham, Ontario

We had our shingles replaced by Cornell Roofing. Chevy was very nice to talk with and helped us decide the various types of shingles and different products available underneath them. The installation date went well. All his workers were hard working, thorough, and professional and the end result showed it. Thanks Cornell. Job Well Done ! Mike works with Cornell in replacing or adding insulation. We got the insulation added to our attic and it has lowered the 2nd floor temperatures especially when its really hot outdoors.
