Standing Seam Metal Roofs

//////////

We provide steel standing seam metal roof systems with expected lives of approximately 40 years. We’ve even enhanced our performance and testing to ensure our products can meet the demands of Hurricane Force Winds. Our standing seam metal roof products are designed and installed to stay attached through even the most devastating of conditions.

We want business and home owners to be oblivious to the weather. For heat or cold, hurricanes or hail storms, rain or shine, our standing seam metal roofing systems offer facility managers and homeowners protection and savings that repay the investment you make in a standing seam metal roof system.

The Steel Roofing Systems we offer are all interlocking, non-exposed fastener systems. They provide the most protection for your home from the elements. These products are available in a variety of colors. These systems can typically be installed over an existing composition roof. Should your old roof need to be removed, we will see that it is recycled.

All of our products are manufactured in America. We support helping to build a healthy economy. While importing steel and aluminum from other countries can be less expensive, the quality is sometimes compromised.

Medallion-Lok

Medallion-Lok by McElroy Metal effectively captures the beauty and elegance of a standing seam roof. Adding curb appeal to any project, the narrow 1.75″ tall standing seam creates crisp, clean visual lines. Medallion-Lok features hidden clips and a snap-together seam which eliminates the need of jobsite seaming. While primarily a commercial panel, Medallion-Lok is also an excellent choice for larger, custom homes.
