What is Aluminum Roofing?


Aluminum is a lightweight and corrosion-resistant metal. It's often used in construction(windows, doors, siding, roofing) and manufacturing(beer and coke cans!). It's a popular choice for metal roofing because of its durability and resistance to rust and corrosion. It's a great option for coastal areas

Aluminum is best used in situations where weight is a concern, such as on lightweight or low-sloped roofs. It's also a top choice for coastal areas because of its resistance to salt corrosion. Additionally, because aluminum is a soft metal, it can be easily formed and shaped into various styles and designs.

Why Choose Aluminum for Your Roof?


RoofCrafters recommends aluminum to homeowners who are looking for a durable and long-lasting metal. It's the best option for homeowners who want a painted metal roof and live in areas prone to salt corrosion. It's more affordable compared to other metal materials, such as copper, lead  or zinc. Plus, aluminum is available in a variety of styles and colors, so it can complement any home's design.

Now lets cover the pros, cons and cost:


  • Lightweight: Aluminum is one of the lightest metals used in roofing, making it a good choice for homes that can't support heavier materials.
  • Corrosion-resistant: Aluminum is resistant to corrosion and rust. It's ideal for coastal areas or regions with high humidity.
  • Fire-resistant: Aluminum has a high melting point and does not burn. Which means it can withstand high temperatures without catching fire. 
  • Energy efficiency: Aluminum has high reflectivity, which means that it reflects the sun's rays instead of absorbing them. This can help to keep your home cooler in the summer and reduce your energy bills.
  • Color options: There are many color options available with aluminum metal roofing. Compared to other types of roofing.
  • Long-lasting: Aluminum roofing can last up to 50+ years with minimal maintenance.
  • Low maintenance: Compared to other roofing materials, aluminum requires minimal maintenance over its lifespan. This will save you time and money in the long run.


  • More Expensive: Aluminum is more expensive than other roofing materials. Such as Steel or Galvalume metal and asphalt shingles.
  • Soft: Aluminum is a softer metal, which makes it more susceptible to denting from hail or falling tree limbs.
  • Noisy: The softness of aluminum can also make it louder during rain or hail storms compared to other roofing materials.

What is Steel Roofing? 


Steel is an incredibly strong and durable metal that has been used in construction for centuries. Steel roofing is a popular choice among homeowners due to its strength, resistance to the elements, and longevity. It's commonly used in commercial buildings, industrial facilities, and residential homes.

Steel is best used in situations where durability and strength are important. It's an excellent choice for areas that experience extreme weather conditions, such as high winds, heavy rain, and hail. Steel roofing is also ideal for homes with flat or low-sloped roofs, as it doesn't crack or break under pressure.

Steel Roofing: Is It Right for You?


We'd recommend steel for homeowners who want a cost-effective and low-maintenance roof. Steel roofing is only available painted. Like a car, it will rust without a paint finish. The good news is it's available in a wide variety of styles and colors. Also, you'll need to live at least 1500 feet away from the ocean. That's about a 10-minute walk in case you're like me and don't get the feet thing! 

Let's cover the pros, cons and costs:


  • Durability: Steel roofing is strong. It's incredibly durable and can withstand harsh weather conditions, including high winds, heavy rain, and hail. 
  • Longevity: With proper installation and maintenance, steel roofing can last up to 50+ years. 
  • Range of gauges: Steel is available in a range of gauges. Including 22, 24, 26, and 29 gauges, allowing for greater flexibility in choosing the appropriate thickness for your home. (24 & 26 gauge are the most popular)

  • Color options: Steel comes in a wide range of colors and styles. You can easily find a design that complements the look of your home. Additionally, steel is often coated with a reflective finish that can help reduce energy costs. Reflecting sunlight and keeping your home cooler in the summer months.
  • Low maintenance: Steel roofing requires minimal maintenance and can be easily cleaned with a pressure washer or by hand. 


  • More expensive: Steel is more expensive than traditional roofing materials like asphalt shingles. It also can be prone to price fluctuations based on market conditions.
  • Heavy: Steel roofing is heavier than other roofing materials. This can cause an increase in labor costs because it's slower and more difficult to install. 
  • Susceptible to rust: If the steel roofing isn't properly coated(paint), it can be susceptible to rust and corrosion over time. 
  • Scratching and denting: Steel roofing can scratch and dent from hail, tree branches, or other debris. If this occurs it will rust, so scratches will need paint.

What is Galvalume Roofing? 


Galvalume is a coated metal product that is made of steel and aluminum coating. It's known for its durability, strength, and resistance to rust and corrosion. Galvalume is a popular choice for metal roofing because it's affordable and lasts as a coastal roofing option.

Galvalume Roofing: Pros, Cons and Cost


We'd recommend a Galvalume roof for homeowners who want a strong and reliable roofing material that's the most affordable. If you love a mill finish metal look and don't want a color on your roof.
