Master Roofers primarily installs GAF shingles — including the Timberline HDZ, Timberline UHDZ, and Camelot II lines — because GAF’s materials meet the performance, warranty, and manufacturer support standards we require for every installation. We also install CertainTeed and Owens Corning products when a specific application calls for them. We do not install no-name or budget-grade shingles on any project.
