When choosing a roofing material, one of the key factors to consider is the weight of the roof. The weight of metal roof vs shingles can significantly impact various aspects of your home’s construction and performance. In this article, we’ll explore the differences between metal roofs and shingles, focusing on their weights, benefits, and considerations to help you make an informed decision for your roofing needs.
Understanding the Weight of Metal Roofs and Shingles
What Determines the Weight of Roofing Materials?
The weight of roofing materials is influenced by several factors:
- Material Composition: The type of material used in the roofing system.
- Thickness: Thicker materials generally weigh more.
- Installation Method: Different installation techniques can affect the overall weight distribution.
Metal Roofs: Lightweight and Durable
Metal roofing has become increasingly popular due to its durability and longevity. Here’s what you need to know about its weight:
- Average Weight: Metal roofs typically weigh between 50 to 150 pounds per square (a square is 100 square feet). This weight varies depending on the type of metal used (e.g., steel, aluminum, copper) and the thickness of the panels.
- Types of Metal Roofing:
- Steel: Generally weighs between 75 to 100 pounds per square. It is a popular choice due to its strength and affordability.
- Aluminum: Lighter than steel, aluminum roofing usually weighs around 50 to 70 pounds per square. It is resistant to corrosion, making it ideal for coastal areas.
- Copper: One of the heaviest metal roofing options, copper weighs around 100 to 150 pounds per square. It is known for its aesthetic appeal and longevity but comes at a higher cost.

Shingles: Traditional and Varied
Asphalt shingles are the most common roofing material in the United States. Here’s a breakdown of their weight:
- Average Weight: Asphalt shingles typically weigh between 200 to 400 pounds per square. The weight depends on the type of shingles and the number of layers used.
- Types of Shingles:
- 3-Tab Shingles: These are the lightest type of asphalt shingles, usually weighing around 200 to 250 pounds per square. They are known for their affordability but have a shorter lifespan.
- Architectural Shingles: Also known as dimensional shingles, these weigh around 300 to 400 pounds per square. They offer better durability and a more upscale appearance compared to 3-tab shingles.
Weight of Metal Roof vs Shingles: Key Comparisons
1. Structural Impact
- Metal Roofs: Due to their lighter weight, metal roofs place less strain on the underlying structure of your home. This can be particularly beneficial for older homes or structures that might not be able to support heavier materials.
- Shingles: Asphalt shingles are significantly heavier, which means they put more load on your home’s structure. For homes with existing roofing, this could necessitate additional support or reinforcement.
2. Installation Considerations
- Metal Roofs: The lighter weight of metal roofing materials makes them easier to handle and install. They can often be installed over existing shingles, reducing the need for a complete roof tear-off and minimizing labor costs.
- Shingles: Installing asphalt shingles usually requires removing the old roofing material to prevent excessive weight and ensure proper installation. This process can be more labor-intensive and time-consuming.
3. Longevity and Maintenance
- Metal Roofs: Although metal roofs are lighter, they are known for their longevity and low maintenance requirements. They are resistant to extreme weather conditions, reducing the need for frequent repairs.
- Shingles: Asphalt shingles generally have a shorter lifespan compared to metal roofs. They may require more frequent maintenance and replacement, especially in areas with severe weather.
4. Energy Efficiency
- Metal Roofs: Metal roofs reflect sunlight, which can help reduce cooling costs during hot months. Their lighter weight also contributes to better energy efficiency by minimizing the load on the building’s structure.
- Shingles: Asphalt shingles absorb heat, which can increase cooling costs during the summer. However, they are available in energy-efficient versions with reflective coatings that can help mitigate this issue.
5. Cost Considerations
- Metal Roofs: While metal roofs are lighter and often require less support, they come with a higher upfront cost. However, their durability and low maintenance can lead to long-term savings.
- Shingles: Asphalt shingles are generally more affordable upfront but may incur higher costs over time due to their shorter lifespan and maintenance needs.
Choosing Between Metal Roofs and Shingles
Factors to Consider
When deciding between metal roofs and shingles, consider the following factors:
- Budget: Evaluate your budget for both initial installation and long-term maintenance costs.
- Home Structure: Assess whether your home’s structure can handle the weight of asphalt shingles or if a lighter metal roof would be more suitable.
- Climate: Consider the local climate and how each roofing material performs in your area’s weather conditions.
- Aesthetic Preferences: Decide which roofing material best complements the overall style and appearance of your home.
Conclusion
Both metal roofs and asphalt shingles offer distinct advantages and disadvantages. The weight of metal roof vs shingles plays a crucial role in determining the best roofing option for your home. Metal roofs provide a lighter, durable alternative with long-term benefits, while asphalt shingles offer a traditional and cost-effective solution with their own set of characteristics. By evaluating the factors discussed, you can make an informed decision that suits your needs and preferences.
