Common Myths of Metal

Updated: May 22

There are several common misconceptions that persist today about metal roofs. Here we dispel those myths and offer the facts about metal roofing. 

Myth: “When it rains, metal roofs are noisy.” Fact: This likely stems from a common experience with the sound that rain makes on old barns and worn buildings. The difference between a barn and residential roof is a solid roof deck. This deck combined with underlayment dampens noise, resulting in a residential metal roof that is no more or less noisy than any other type of roof.  Myth: “You can’t walk on a metal roof.” Fact: Metal roofing is very durable. You can safely walk on a metal roof without causing damage to the panel. Having a solid roof deck provides extra stability to hold a person’s weight. Myth: “Metal roofs rust.” Fact: Metal roofs have come a long way. Metal Sales roofing features a protective Galvalume® or galvanized coating over the base metal and employ high-quality color systems that carry industry-leading warranties. The advanced alloys in these protective coatings ensure that your metal roof will remain impervious to corrosion for decades to come. 

Myth: “Metal roofs get struck by lightning.” Fact: Lightning strikes the highest point in an area, regardless of the material of the impact point. Metal roofs have the same chance of being struck as asphalt shingle, slate, wood or any other type of roof material.  Myth: “Metal roofs are hot.” Fact: All roofs get hot. However, metal roofs come in a variety of ‘cool’ colors that reflect solar heat. Metal also releases solar heat quicker than asphalt shingles, actually reducing the heat load on a home. According to the Heat Island Group of Lawrence Berkeley National Laboratory, reflective metal roofs reduce the need for cooling buildings during hot summer months by up to 40%, saving energy and money. Myth: “Metal roofs are heavy.” Fact: Surprisingly, metal roofing is generally 50% lighter than an asphalt roof and 75% lighter than concrete tile, fiber cement shakes and slate.
