About Corey MacKinnon

Being a Whistler local since 1995, Corey came to town as a professional Chef. He fell in love with the mountains and the community which solidified his decision to lay his roots here.

After many years in the hospitality industry and starting a family, he decided a new direction was needed. While working for an RCABC local roofing company for 8yrs, Corey went back to school and received his Journeyman Red Seal Certificate in roofing.

In 2011, Corey received the Top Roofing Apprentice Award for the Lower Mainland area, besting 850 of his peers.

Corey strongly believes that the passage of knowledge, whether to the client or his employees, is an important part of the process as a tradesman, teacher, owner, and leader. He believes that it is a part of paying the roofing trade forward which helps his team with developing their skills as they are an extension of the company when he is not on-site.

Corey is a detailed oriented individual with a strong work ethic, excellent task management skills and conveys the same vision for the company to ensure that it is embraced by everyone.
