Types of Metal Roofing… There are really three types.
The first and most common type of metal roof is the vertical panel many people know it as “standing seam” there are many types of vertical panel and standing seam is just one of many. The two pictures below are examples of a vertical panel.
Just a few of the many benefits of choosing a metal roof are… it is possible to get a home insurance discount. Some insurance agencies don’t give discounts for metal roofs, but others do. Each insurance agency will have different rules to qualify for the discount, and the size of the discount will depend on the insurance agency. However some areas that have mandatory discounts for certain roof types determined by state insurance boards. The environmental hazards in every area are different so discounts often vary by region. 30% discounts in many regions are possible. Federal tax credits till the end of 2013 for energy star certified metal roofs (10% of cost, up to $500).
The second type, which is most popular in residential areas is the Metal Shake. This can come in aluminum or steel, and there are many variations, Spanish tile, wood shake, slate, etc.
Metal roofs generally have a high amount of recycled content. The exact amount of recycled content varies greatly so if you are concerned about how much recycled content is actually in your metal roofing system of choice contact its manufacturer. Whether or not they were made from recycled material all metal roofs are recyclable. Long lasting warranties. 40-50 year warranties are quite common with metal roofs. This means that a metal roof is likely to last much longer than 40-50 years. It’s not hard to imagine that if you live in the same house your whole life you’ll never have to get another roof if it’s metal.
The third type of metal roof is a stone coated steel, which comes in a shake or tile design. This type of panel is not really considered a permanent solution because the granules do come off over a relatively short period of time, and they tend to mold and mildew quickly, but it is better than a composite roof.
Stone Coated Steel
Snow is not a problem for metal roofs. The main thing to be concerned about is whether the structure can handle the added weight of the snow. Increases the value of your home. The value added won’t be more than what you pay for the metal roof, but most of the cost will translate into value in your home.

One of these protective coatings is usually another metal that has corrosion resistance like zinc or aluminum. Metal roofs weigh less than almost any other roofing material per square foot. It is a common misconception that a metal roof is heavier than other materials, but because of the durability and other properties of metal it is possible to make a metal roof lighter than other materials. In fact, a metal roof is light enough to put on top of most existing roofs today.
Metal roofs do not grow mold and mildew like their counterparts, with the exception of stone coated steel. Most modern metal roofs have protection against rust. When galvalume is cut or bent the protective layers are damaged or removed from those parts and so some corrosion does happen, but doesn’t get worse. Some natural metal roofs like zinc and copper acquire a patina over time on the outside of the metal that protects the rest of the metal from corrosion. Should this patina be scratched the metal basically heals itself as the patina reforms over the scratch and looks just like it did before. Steel roofs have protective coatings that keep the steel from rusting.
