Metal roofs are impact and fire-resistant, making them good for use on porch areas. Unlike asphalt roofs that trap heat, metal roofs reflect it, keeping an area cooler and enabling homeowners to save on air conditioning costs.
White metal roofs have the highest heat reflection rate. In some areas, using metal roofing may allow homeowners to get discounts on insurance. Metal roofs also seal out water, are impervious to rain, shed snow and can survive high winds. They are also resistant to insect damage and mildew.
A metal roof is quick to install and is durable and long-lasting, reducing upkeep and maintenance costs. Metal roofs are also lightweight and are primarily made of aluminum and steel. They come in styles that include standing seam, metal shingles or shakes.
One metal roof drawback for a porch area may be noise. In a rain or hail storm, metal roofing can produce more sound. Using materials that provide a structural barrier can help to reduce noise.
