The torching on the deck was impeccable. The pride you take in your work and attention to details resulted in perfection. We were also very grateful that though we contacted you at the last minute, you went above and beyond to accommodate us and fit us into your very busy schedule.

Corey was professional from start to finish. He explained the entire process before starting, used top-quality Soprema materials, and left the site immaculate. I wouldn't trust my roof to anyone else in Squamish.
