Western Roofing Company History

Sandy Sanderson started Western Roofing as a small business in 1995. Founded on the values of service, quality and commitment in the areas of roofing maintenance, repair and replacement for commercial and institutional business owners, Sandy began relationship with Duro-Last, a privately held roof manufacturing company that has been a leader in quality with its comprehensive “edge to edge, deck to sky” approach to manufacturing and materials guarantee.


Within his first year Sandy hired Curtis Nicholson who quickly demonstrated his ability to build on the company’s foundation through strong client relationships. The business quickly doubled, and then doubled again through the commitment to communication, service and follow-up.

During the mid 90’s Western began documenting rooftops, first with a Polaroid instant camera, and more recently, with digital cameras. At first the goal was to document repairs in problematic roof areas where repeated leaks would occur. Quickly we realized thorough documentation of rooftops gave us an edge. We could support clients in warranty and insurance claims by demonstrating they have met or exceeded their warranty and insurance maintenance responsibility.


Curtis became a partner and continued to refine the operational practices of the business.


Western Roofing continued to grow, moving locations in Golden Colorado two times. Growth came out of our commitment to client relationships, educating clients about their roof, setting the standard that work is conducted by hourly employees rather than subcontractors, and investing in the tools, vehicles and infrastructure to support longevity in the roofing industry.


Two big changes occurred in 2009, Curtis bought out Sandy, becoming the sole business owner of Western Roofing. That same year, to continue our work with client insurance and warranty claims, Western Roofing bought a seat in Xactimate, the insurance software used by adjusters. This investment allows us to independently assess damage and prepare reports to back up your claim.


Western Roofing purchased the building at our current location in Wheat Ridge, Colorado, again, reinforcing our commitment to roofing right and maintaining


To expand our capacity and to take on larger projects, Western Roofing brought on an experienced General Manager to coordinate logistics for roofing multi-story apartment buildings, skyscrapers, historic buildings and industrial towers. We partner with crane services and traffic control providers to maintain a safe and managed process to roof your high rise or complex project.


Western Roofing’s long-term commitment to quality, and our partnership with Duro-Last has resulted in Western being the only Master Installer and Elite Contractor for DuroLast in the Denver Metropolitan area. In 2017 we received the Eagle award for rank of 95% or above on installs and volume of work. Western Roofing has installed over 2,000 DuroLast projects with over 13 million square feet of surface coverage.
