Was delighted to have quality work done in a timely manner. Especially considering the demand in the construction industry right now where sometimes even getting a call back seems like an oddity. Will return for future roofing needs.

My realtor suggested Damen at Peak to Peak for a roof replacement through our insurance. We were on a timeline to sell our home, and Damen was an absolute rock star. He answered the call on a Sunday night, showed up for an inspection and helped us through the process - getting the entire job done within a couple short weeks. The roof looks amazing, and Damen also met with our insurance adjuster and added the gutters and garage door. I can't say enough about the professionalism, communication, availability and work that Damen and Peak to Peak provide. Give them a call - you won't regret it!
