When considering the cost to install a metal roof over shingles, it's essential to factor in both materials and labor. Metal roofing often provides a durable and long-lasting solution that can save money in the long run compared to traditional shingles. The cost may vary depending on the type of metal used, such as aluminum or steel, and the complexity of the roof design. Local roofers can provide an accurate estimate, ensuring that all potential challenges are accounted for in the pricing. Opting for a metal roof over existing shingles can also reduce installation time and waste removal expenses.
