Types of Metal Roofs and Their Pros and Cons

Your asphalt roof is faded and worn.

You need a new roof, and you don’t want to replace it in 20 years.

So you’re switching to a metal roof.

But what material is best for your home? Aluminum? Steel?

What panel type?

There are a few options to choose from, so let’s break it down.

Types of Metal Roof Materials

Aluminum

Aluminum, a lightweight and corrosion-resistant metal, is an excellent choice for residential roofing. Its corrosion resistance makes it suitable for coastal areas or regions with high humidity.

While lightweight, aluminum is softer than steel, making it more susceptible to denting in severe weather conditions. Despite being more expensive up front, aluminum roofs can have a long lifespan.

• Expense Level: Medium
• Ideal Climate: any temperature, any humidity level, light to moderate storms
• Lifespan in Ideal Climate: 50+ years

Steel

Steel, a robust and versatile metal, is widely used in various construction applications, including roofing. Known for its strength and durability, steel provides excellent protection against harsh weather conditions.

Despite being more budget-friendly than aluminum, untreated steel is prone to corrosion, which can be mitigated with galvanization or coatings. However, steel is heavier than aluminum, potentially requiring additional structural support during installation.

• Expense Level: Low
• Ideal Climate: any temperature, low (ungalvanized) to high humidity (galvanized), light to severe storms
• Lifespan in Ideal Climate: 30 to 50 years

Copper

Copper, a premium metal choice, is known for its distinctive appearance and longevity. Copper roofs develop a unique patina over time, giving a timeless and elegant look.

While copper is one of the most expensive roofing materials, its roofs can last well over 100 years with minimal maintenance.

Working with copper requires specialized skills, potentially leading to higher installation costs.

• Expense Level: High
• Ideal Climate: moderate temperatures, low to moderate humidity, light to moderate storms, low air pollution
• Lifespan in Ideal Climate: 70 to 100+ years

Zinc

Zinc is emerging as a compelling choice for roofing materials, characterized by its unique set of attributes.

Over time, zinc roofs develop a protective layer that grants them a self-healing ability, effectively addressing minor scratches and imperfections. Beyond durability, zinc offers a distinctive aesthetic appeal, initially presenting a shiny surface that gradually transforms into a matte gray patina, adding character to the structure.

However, it’s important to note that the premium qualities of zinc come with an elevated upfront cost, making it a choice that aligns with those who prioritize long-term benefits.

Working with zinc requires specialized skills during installation, contributing to overall project costs. 

• Expense Level: High
• Ideal Climate: any temperature, low to moderate humidity, light to moderate storms, low air pollution
• Lifespan in Ideal Climate: 50 to 100+ years

Types of Metal Roof Panels

V-Ribs

V-rib panels, with their V-shaped profile, are a popular choice for both residential and commercial applications. The V-shape enhances water shedding, reducing the risk of leaks.

V-rib panels offer a classic and versatile appearance, though they may show waviness, known as oil canning, depending on factors like metal thickness and installation.

Bead Ribs

Bead rib panels feature raised beads, providing a distinctive look while offering practical benefits. The raised beads add strength and rigidity to the panels, creating visual interest and texture on the roof.

However, installation may be more complex due to the raised beads.

Pencil Ribs

Pencil rib panels have smaller, closely spaced ribs, creating a subtle and refined appearance. Pencil ribs contribute to a modern and sleek aesthetic and can enhance wind resistance, preventing uplift.

The small spaces between ribs can trap debris, requiring periodic cleaning.

Striated

Striated panels feature horizontal lines, offering a clean and contemporary look. Striated panels contribute to a modern and streamlined appearance, with some options coming with concealed fasteners for improved aesthetics. 

However, concealed fasteners require more time and skill during installation.

Flat

Flat panels provide a clean and simple aesthetic, suitable for modern and minimalist designs. Flat panels contribute to a sleek and uncluttered roof design and are generally easier to install compared to ribbed options. 

However, flat panels have less efficient water shedding compared to ribbed alternatives.

Clip Relief

Clip relief panels have raised sections at the edges, creating a visually interesting profile. Clip relief adds visual interest and depth to the roof, potentially allowing for increased airflow beneath the panels.

However, clip relief panels are more expensive than simpler options.
