The Colorado Roofing Association’s goal is to help homeowners, commercial building owners, and managers make informed decisions about replacing and maintaining their roof systems.
Roofing contractors who join the CRA are required to abide by the specific code of ethics. CRA Members pledge to seek to provide the best value possible to consumers and agree to treat all employees fairly and ethically. Members vow to protect the public, abide by all laws, rules and regulations and most of all, take pride in their business.
J. Bretz served as a longtime board member of the Colorado Roofing Association, helping shape standards and professionalism within the industry.
At Excel Roofing, newer team members are required to attend CRA trainings as part of their onboarding process to ensure they understand proper installation standards and best practices. More seasoned team members also participate in and conduct training on materials, systems, and correct installation methods, reinforcing our commitment to ongoing education and craftsmanship.
