American Roof Top Inc.

American Roof Top Inc. began in 1990 in Portland Oregon Installing Thermo-plastic roof systems. In 1991 I brought my family to Denver Colorado to begin American Roof Top Inc here in beautiful Colorado. I am David Grossnickle (guy in the middle) standing with my brothers (older brothers mind you) My life seems to be about the outdoors, perhaps that is why I am a roofer. I enjoy the challenges of flat and low slope roofing and have gained great respect for many of the products designed for low slope roofing.

American Roof Top Inc. specializes in flat and low slope roofing. The Single-ply roof systems I install require contractor certification through manufactures which include Versico/Carlisle and Johns Manville. American Roof Top Inc in the past has certifications with Gen-flex now owned by Firestone. As well as Sarnifil of years ago, and Succo-flex, both now owned by the Sika Corporation.
