Metal Roofing Vs Slate Roofing

Slate roofing, made from natural slate rock, is popular for its unique aesthetic. Unfortunately, slate requires a high degree of maintenance, especially when slate shingles become loose or break. Metal roofing can mimic the look of slate without the costly maintenance. Plus, it’s highly durable, meant to last a lifetime.
