The Master Elite title isn’t a widely-used rubber stamp. You must be committed to serious quality, customer service, and ongoing training to earn the distinction. Every Roof Worx employee attends annual training on how to properly install GAF systems, which GAF experts then inspect. Only about 1% of Colorado roofers make the grade. This also means we can upgrade warranties that provide up to 30 years of workmanship and 50 years of material coverage.
