The Reliability of Standing Seam Metal Roofs

Replacement Roof: Metal Standing Seam, Forest Green Colour

A standing seam metal roof is perfect for this log home in rural Alberta. Fully interlocking panels provide weatherproof protection for many decades to come.

Part of this replacement project included the replacement of insulation in the attic of the home.

Another feature of the standing seam profile is that it can be used for fully vertical applications.

Standing Seam Panels

Standing seam panels are designed with two primary seaming options to meet different needs: single lock and double lock systems. The single lock option is best suited for residential roofs with standard slopes and facades, providing reliable performance in typical applications. For low-slope roofs, the double lock system offers enhanced seam strength and a watertight seal that excels in Alberta’s tough climate. This design ensures added protection against water infiltration, making it particularly effective in withstanding snow, wind, and fluctuating temperatures.

Each panel’s seams are mechanically locked using specialized tools. This technique creates an exceptionally strong bond that provides outstanding resistance to wind uplift with excellent weatherproofing, which is especially crucial in Alberta’s extreme conditions. Usually, the height of the locks ranges from 1 to 2.5 inches, while the panel widths are to be specified for each particular project. Panel design accounts for natural expansion and contraction without warping or loosening over time. Because metal roofing focuses on long-term value, it offers the ideal blend of durability, efficiency, and refined aesthetics desired by most homeowners.
