About Alliance Roofing Company, Inc. 

Alliance Roofing Company Inc., established in 1986 by Rod Miller, is committed to delivering the highest quality roofing systems available.

  • Our vision encompasses exceeding client expectations, continually raising the bar of excellence, and fostering a safe environment where employees thrive, enjoy their work, and feel integral to the team. This vision has propelled Alliance to the forefront of the roofing and waterproofing industry in Northern California.

  • Initially, Alliance Roofing was solely a re-roofing company. Over time, we have expanded and evolved with the industry, leading in several areas. We were pioneers in entering the PVC/TPO market, mastering metal roofing, and delving into below-grade waterproofing.

Alliance Roofing stands as the largest union Roofing Company in the Bay Area, renowned for our innovative approach to roofing and waterproofing technologies. We have established strong relationships with general contractors, private companies, property managers, and manufacturers.
