A growing trend in the home roofing industry these days is the metal roof. With qualities of light weight, durability and fire resistance, there are various metal roofing materials and systems to consider.
Some of the newer metal roofing materials are even designed to give your roof the look of wood shakes or slate tile. A wide variety of metal roofing systems is available on the market today.
A 2007 member survey by the National Roofing Contractors Association provides evidence that up to thirty percent of new homes now use architectural metal roofs, up from only twenty-three percent in 2004.
Types of Metal Roofing Materials Used
The primary metals used to make metal roofing materials include aluminum, steel, stainless steel, copper, and zinc alloys. Each metal roofing material has unique properties that affect its appearance, durability and price.
Heavier and more durable than aluminum, steel is a popular choice for metal roofing. Coated with zinc and sealed to provide a finish that protects it against rust and corrosion, a modern steel roof, installed properly, can last fifty years or longer.
The coatings typically consist of a bottom coat of epoxy primer, which provides additional adhesion, and an acrylic top coating, which is baked on to add protection and color that will withstand harsh sunlight, rain, snow and ice.
Stainless steel is another popular, but more expensive, metal roofing material that is highly resistant to rust and corrosion. A Terne coating may also be used to give stainless steel roofing material a more natural, matte-gray finish.
Aluminum roofing materials are extremely lightweight, making them another choice for home roofing. While aluminum doesn’t rust, it does need to be painted or coated to provide a more attractive appearance. The coatings used on aluminum roofing are similar to those used on steel roofing materials.
Copper has been used as a roofing material for centuries and offers a rust-free surface that is naturally resistant to scratching or peeling and develops a natural patina with time that is quite attractive. However, copper is extremely expensive and thus, less commonly used as a home roofing material these days.
