We believe that GAF (American Harvest) is The Best Value out there - the wind rating, the stain guard guaranteed, and the workmanship guaranteed was far more superior on this product. Don and Thanh were very accessible and knowledgeable. The work was completed in a professional manner in just a couple of days. THE END RESULTS was BEAUTIFUL!!!!! Not the end yet, this roof has a “one time” transferable warranty which has GREAT “resale” value.
