While not a drawback, per say, an important consideration is that aluminum is highly ductile, meaning it’s flexible and formable, and can endure a great deal of stress without losing its strength. Simply put, it’s the opposite of brittle. Aluminum’s ductility is helpful for fabricating our roofing panels with precision, as well as preventing cracks or breaks in your roof. But this same attribute makes it more susceptible to cosmetic denting, so care should be taken to prevent this. To minimize the risk of denting, aluminum roofing should be installed over sheathing, kept free from overhanging branches, and foot traffic should be limited to supported sections, especially on ridge caps.
