The Top Four
– Steel is the most common material used. Professionally-installed, steel tiles could last well over 60 years. A sturdy and durable material, it is often coated with zinc to protect it from corroding. Steel can be colored using a baked-on, acrylic coating. Galvanized steel is inherently resistant to rust.
– Copper is one of the higher-end types of metal roofing. This is, by far, the most long-lasting of all housing lids. It is also one of the most expensive, and it’s become increasingly hard to find. On a copper roof, there isn’t a need for a coating, and it weathers beautifully. It is naturally resistant to corrosion; it is low maintenance, and it offers radio frequency shielding. On the other hand, this material is highly susceptible to theft.
– Aluminum is a lightweight option, but it has some high costs involved. The main benefit is that your house will be kept cooler. This type of sheeting dents easily, must be painted or coated for color, and has a hard time keeping its shape over the years due to it being soft. An aluminum top will last about 35 years.
– The classic “tin” roof, or terne/terneplate, is actually just another form of treated steel. Much like aluminum, the terne must be painted, but keeping the paint well-maintained could make your top last for 90 plus years.
The Ups And Downs
The different materials aren’t the only things to know about metal roofing. When deciding on a type of housing lid, it is also good to take a look at the overall benefits. With a metal roof, it may cost more for the materials and installation up front, but the long-term benefits are well worth it. Many worry about the noise that comes along with a metal lid, but with the proper shielding and insulation, that doesn’t have to be a problem. Another thing to keep in mind is the area where the lid will be installed. Areas with salty sea air may shorten the life of your lid, and the same is true for areas with heavy air pollution. When choosing a type of roofing, you will also need to consider the weather conditions. Metal tops are fire-resistant, which is good food for thought if your home has a fireplace or furnace.
Regardless of why you are looking into metal roofing, keeping these factors in mind could help you make an informed decision.
