Aluminum is a great choice for your roofing needs. It has a long lifespan, lasting up to 50 years or more, and it’s lightweight which means it’s easy to install. In addition to being extremely durable, aluminum is also resistant to corrosion and can withstand temperatures as low as -60 degrees Fahrenheit. Aluminum also carries an R-value rating of over 50, so it will keep your home warm in the winter months and cool in the summertime.
Steel is also an excellent option as a roofing material because it’s strong enough to support heavy loads without bowing or buckling under pressure like other metals might do under heavy wind gusts or snowfall amounts that are too heavy for them (such as hail). Steel has an R-value rating of about 32; however, steel does not have any insulation properties which means that its thermal resistance value may decrease significantly with age depending on how well it has been cared for over time
