Our Story

Joshua along with brother, Josiah, learned the art of roofing at a very young age, thanks to their father, Gerry Thiesen. Gerry mentored and trained others across the country, built a reputable company, and raised three young men with outstanding character. He will always be remembered, and we are so thankful to both him and his wife, Carol Thiesen, for their dedication to this family business. With 35 years of excellence as G & C Enterprises, GC Roofing picked up the baton and has continued the heritage.
