This house has GAF Timberline HD Shingle in the Slate color. We used GAF Pro Start Starter shingle. One the Ridge we used GAF Z-Ridge Hip & Ridge. We also used GAF Tiger Paw Underlayment and attached it directly to the CDX Plywood decking. Part of the roof had GAF Weather Watch Ice & Water Shield. We decided to use Snow Country Advanced Ridge Vent for the roof venting. It is a beautiful roof that will stand the test of time and the homeowner is very happy!
