Trained and Certified Professional Roofers

Wedge Roofing Trained Professional Roofers

Wedge Roofing employs a team of highly skilled roofing craftsman comprised of California State Certified Journey-level Roofers. These professional roofers have graduated from an intensive forty–four month classroom and on-site training program offered by the California State Office of Industrial Relations Division of Apprenticeship Standards, which provides mastery in all steep-slope and low-slope roofing systems, spray foam roofing, rooftop carpentry and safety procedures.

Exceeding the stringent requirements of this California State sponsored program, Wedge Roofing is authorized to provide on-site training for apprentices to become state-certified journeyman roofers. Ralph Wedge, as a founding member and current treasurer of the Independent Roofing Contractors of California, was instrumental in establishing and monitoring this federally and state-recognized roofing apprenticeship program.

Few contractors pursue continual education and training of their crews and even fewer are authorized to participate in this state program, despite the fact that on-going training is one of the most important aspects of quality and safe roofing.

Although not required by the State of California, Wedge Roofing Journeymen continue to expand their roof mastery through postgraduate training in their chosen roof specialties of spray foam roofing, shingle roofing, metal roofs, slate and tile roofs, single-ply roof systems, built-up roofing and Title 24 Cool Roof systems. We are proud that through their commitment to on-going education, we are able to offer our clients highly trained and experienced roofing professionals.

Our staff and crew have successfully completed the following training programs (partial list):

  • GAF, CertainTeed,Carlisle, Durolast, and Firestone Factory Training
  • American Institute of Architects Continuing Education: Historic Preservation, Cool Roofs
  • Certified Lead Renovator by the U.S. Environmental Protection Agency
