When considering metal roof installation over asphalt shingles, the primary reason for doing so is to preserve your roof and protect it against harsh outside elements. Usually, installing a metal roof over shingles will protect the roof from wear and tear. One of its beneficial factors is its energy efficiency, saving you up to 40% in energy costs.

One of the primary benefits when installing a metal roof over shingles is that it’s eco-friendly. By installing a metal roof over shingles, you don’t have to throw them away. It keeps them protected and preserved, preventing potential damage that might significantly affect your roof. Another advantage is that most metal roofs are made from 40% recycled metal materials.

Although periodically inspecting your roof is essential, you don’t have to worry about repairs, as most would with asphalt roof shingles.
