New Roof - Without question, Cornerstone was the best partner to hire for our new roof. Needing the expertise on cold roofs and the differences in our Alpine environment, these guys are the pros. There are other good companies, I am sure, but we believe that we worked with the best when it comes to the needs and engineering of a project on our home. Cornerstone's process was very clear and concise when it came to scheduling, estimating, payments and project management. Most of all they run a very clean work site with attention to detail. They did new copper gutters too, that we love and have had many complements.
Highly recommend!!

As a general contractor, I’ve worked with CMS on numerous new builds and re-roof projects, and they are our go-to team. Their crews show up on time, stay on schedule, and deliver high- quality work every single time. Communication is straightforward and professional, which makes coordination on busy job sites smooth and easy. They handle everything from prep to cleanup with care, and I never have to worry about callbacks or quality issues. It’s great having a trade partner I can count on to get the job done right. Highly recommended.
