Metal roofing is known for its resilience. Unlike traditional roofing materials like asphalt shingles, metal roofs can withstand the elements such as strong winds, heavy rain, snow, and even hail. This durability translates to a much longer lifespan, often exceeding 50 years with proper maintenance. Choosing a 20 ft length reduces the number of seams, which are potential leak points, thereby enhancing the roof's longevity.
