A Comparison of Steel and Aluminum Roofs

Metal roofing was once only found on commercial buildings. Given its durability, energy efficiency, low-maintenance features, lightweight and contemporary look, it is now becoming a popular choice for homeowners. There is a wide array of metals to choose from, such as zinc and copper.  In this blog post, we compare the two most common options: steel and aluminum.

Why Choose Steel?

Steel is the most common roofing material given its affordability. Generally, steel is cheaper than aluminum.

When it comes to locations commonly affected by hurricane and storm damage in and around Baton Rouge LA, steel is a better option since it is 2.5x denser than aluminum. It can withstand winds up to 110-150 mph and its density also makes it more resistant to high heat. This is the metal of choice then for areas susceptible to fire.

If you walk on the roof often or have a lot of nearby trees that might drop branches on the roof, steel will provide better performance as it is less vulnerable to denting.

Why Choose Aluminum?

Aluminum is the lightest metal used for roofing. It is 1/3 the weight of steel, thus it will mean less load on the house’s structure. In fact, it has one of the highest strength-to-weight ratios in common metals. This is the reason why it is the metal utilized in aircraft.

Its lightweight and thinness also translate to its energy efficiency. It absorbs less heat and quickly cools down, thereby reducing cooling demands. Since it is a softer metal than steel, it is also more malleable and easier to work with on site.

As a non-ferrous metal, aluminum provides superior resistance to rust and corrosion. If you are residing in a coastal area, aluminum will deliver greater protection against seawater.
