The final phase of the commercial reroof at First Interstate Bank in Great Falls, Montana was the installation of a new Class 4 Malarkey Vista® AR architectural asphalt shingle roofing system. After completing the demolition of the existing roof, inspecting the roof deck, and installing premium Malarkey roofing underlayment, Montana Pro Contractors installed one of the industry's highest-performing architectural asphalt shingle systems. The completed 23,000-square-foot commercial roof was engineered to provide exceptional protection against Montana's high winds, hail, heavy snow loads, freeze-thaw cycles, and intense UV exposure. Every successful commercial roofing project depends on proper installation. Even premium roofing materials can underperform if they are not installed according to manufacturer specifications and industry best practices. At Montana Pro Contractors, every phase of the installation process is completed with precision to maximize the performance, durability, and lifespan of the finished roofing system. Our commercial roofing team carefully established layout lines to maintain consistent shingle alignment across the roof. Each Malarkey Vista® AR Class 4 architectural shingle was installed using manufacturer-approved fastening patterns and proper nail placement to ensure outstanding wind resistance and long-term structural performance. Accurate fastening is essential on large commercial roofing projects because it helps each shingle resist uplift during Montana's frequent high-wind events while maintaining a uniform architectural appearance. The Malarkey Vista® AR roofing system is manufactured using SBS polymer-modified asphalt, providing increased flexibility compared to traditional asphalt shingles. This advanced technology allows the shingles to better withstand thermal expansion, contraction, and impact while maintaining their protective seal through years of changing weather conditions. Combined with a Class 4 impact rating, the roofing system offers superior resistance to hail, wind-driven debris, and severe storms commonly experienced throughout Great Falls and Central Montana. During installation, special attention was given to valleys, ridges, hips, roof penetrations, flashing transitions, and roof edges. These areas experience some of the greatest exposure to water infiltration and wind uplift, making proper detailing critical to the long-term success of the roofing system. Every flashing component was integrated with the premium Malarkey underlayment to create a continuous waterproof barrier that protects the building beneath. Ventilation also plays an important role in the performance of an architectural asphalt shingle roof. A properly balanced roofing system helps regulate attic temperatures, reduce moisture accumulation, improve energy efficiency, and extend the service life of roofing materials. Montana Pro Contractors evaluates ventilation requirements as part of every commercial roof replacement to ensure the completed roofing assembly performs as a complete system rather than as individual components. The installation of Class 4 Malarkey Vista® AR architectural shingles provides First Interstate Bank with a premium commercial roofing system designed for decades of dependable performance. The finished roof offers exceptional wind resistance, impact protection, waterproofing, and long-term durability while enhancing the appearance of one of Great Falls' prominent commercial properties. Choosing a premium architectural shingle also provides lasting value by reducing maintenance requirements and improving overall roof performance throughout its service life.
