Pros and Cons of Metal Roofing: A Comprehensive Guide

Advantages of Metal Roofing

Longevity

One of the most appealing features of metal roofing is its durability and long lifespan.

When installed correctly, a metal roof can last between 40 and 70 years, far outlasting traditional asphalt roofing, which generally lasts only 12 to 20 years.

Energy Efficiency

Metal roofing is highly energy-efficient, especially in warmer climates. Its reflective surface minimizes heat absorption, reducing cooling costs during summer.

Some specialized coatings can re-emit absorbed solar heat, enhancing your home’s energy efficiency.

Environmentally Friendly

Metal roofs are often manufactured from recycled materials, and at the end of their lifespan, they are 100% recyclable.

This eco-friendly attribute can contribute to building certifications like LEED and significantly reduce your home’s environmental impact.

Low Maintenance

Another perk of metal roofing is its low maintenance requirements. Unlike roofs made from asphalt or wood, metal roofs are not susceptible to rot, insects, or mildew.

An occasional cleaning and inspection are generally all needed to keep a metal roof in good condition.

Safety Features

Metal roofs are non-combustible and typically have a Class A fire rating, the highest available.

This characteristic makes them a safe choice, particularly in areas where wildfires are a concern.

Wind Resistance

Due to their sturdy construction and interlocking panels, metal roofs are highly wind-resistant able to withstand gusts up to 140 miles per hour.

This makes them an excellent choice in hurricane-prone areas.

Versatility in Design

While not as varied as other roofing materials, modern metal roofing does come in multiple styles, textures, and colors, enabling homeowners to choose options that complement their home’s architectural style.

Lightweight

Metal roofs are lighter than other roofing materials like tile or asphalt, so they put less structural stress on your home.

This is especially beneficial for homes that cannot support heavier roofing materials.

Resale Value

Investing in a metal roof can significantly increase your home’s resale value. The longevity and low maintenance of metal roofs are selling points that prospective buyers often appreciate.

By evaluating these advantages, homeowners and building owners can decide whether metal roofing is the right option for their needs.

Initial Cost

Metal roofing is generally more expensive upfront compared to other roofing materials. However, the long-term benefits often offset these initial costs.

Noise Factor

Rain or hail on a metal roof can be louder than on other types of roofing. Insulation can mitigate this, but it’s an additional cost to consider.

Denting

Although metal roofs are tough, they can still be dented from severe hail or falling tree limbs. Some types of metal roofing materials are more prone to this than others.

Limited Aesthetic Options

While metal roofing comes in various styles and colors, the choices are not as abundant as other materials like asphalt shingles. This limitation could be a turn-off for those who have specific aesthetic preferences.

Expansion and Contraction

The metal expands and contracts with temperature changes. Over time, this can lead to a “wavy” effect if not properly installed, which may require adjustments.

Which One Is Better: Metal Roofing or Traditional Roofing?

Deciding between metal and traditional roofing involves thoroughly evaluating various factors, from cost to longevity to aesthetic preferences.

Below are some points to consider when making this important decision.

Cost

While metal roofing generally has a higher upfront cost, it offers long-term value with lower maintenance and potential energy savings.

Traditional asphalt roofing is initially cheaper but may require frequent replacement and repairs.

Longevity

Metal roofing boasts a lifespan of 40 to 70 years, considerably longer than traditional asphalt shingles, which typically last about 12 to 20 years.

Maintenance

Metal roofing requires minimal upkeep, primarily occasional cleaning and inspections.

Traditional roofing materials like asphalt or wood may require frequent maintenance, including re-shingling and dealing with moss and algae growth.

Energy Efficiency

Metal roofs are superior in reflecting solar heat, making your home more energy-efficient, especially in hot climates. Asphalt roofs do not offer the same level of energy savings.

Environmental Impact

Metal roofing is often made from recycled materials and is fully recyclable at the end of its life. Asphalt shingles are less eco-friendly, as they are a petroleum-based product and often end up in landfills.

Safety

Metal roofs have a Class A fire rating and are non-combustible, making them a safer choice in areas prone to wildfires. Traditional roofing materials do not generally offer the same level of fire resistance.

Aesthetics

While metal roofing options have expanded recently, traditional roofing materials still provide a broader range of styles and colors. Your aesthetic preference may be a significant factor in your decision.

Installation

Metal roofing can be quicker to install but requires specialized knowledge and skills. Traditional roofing materials are commonly used and easier to install but may take longer.

Resale Value

Homes with metal roofs often have a higher resale value due to the material’s longevity and low maintenance. Asphalt roofing doesn’t have the same selling point, especially if it is near the end of its lifespan.
