I am trying to decide on a shingle and metal roof combination that would work best for my coastal style home in Florida. Most of the roof is shingle with metal over front porch and garage. I am planning on BM White Dove exterior with Farrow and Ball Parma Blue doors and shutters. I am deciding between GAF Birchwood shingle and Dove gray metal or Oyster Gray shingle with pre weathered galvalume metal color. Does anyone have experience with either of these combinations? I will attach photo of house exterior drawing. Thank you!!
