A Rich History with a Focus on Service and Excellence

In 1987, Calvin Nissley, Jr. first began selling roofing metal as a service to help his local friends and farmers in Pleasant Valley, located in Oakland in Garrett County, Md. 

Today, CN Metals is western Maryland’s premier leader in steel metal roofing and siding for both residential and commercial uses. Over the past 35 years, the family-owned and operated company has expanded its product offerings and services, including the addition of employees and infrastructure to support Calvin’s initial business idea.

CN Metals also offers portable storage buildings, post frame buildings, garage doors, and provides customers with delivery and installation services. By partnering with AMS Financial Solutions, Inc., customers now have the option to apply for 100% free financing for their next project.

Serving the four states of Maryland, Pennsylvania, Virginia and West Virginia, CN Metals strives to provide their customers with exceptional service and high-quality products.  In-house design services are also available for home improvement projects.

Experienced installers provide full-service garage door and opener installation at private homes or businesses. Trained staff members look forward to helping any customer design a post frame building or garage, and will provide a quote for the project.

CN Metals has an outstanding reputation for high-quality products and providing excellent customer service, and are always thinking of how to continually evolve and grow as a business to meet the needs and wants of their customers in the surrounding region.

In 2022, CN Metals began manufacturing and producing their own metal roofing panels, known as C-Lok. With the addition of our C-Lok product, CN Metals continues to provide customers and preferred contractors with the highest-quality products and added value.

We encourage you to stop by or contact us to see how we can assist you with your next home improvement or building project.
