Metal roofing has become an increasingly popular choice for commercial buildings. This guide will equip property managers with everything they need to know about metal roofing systems before investing in a roof replacement or installation.
We’ll delve into materials, shapes, benefits, drawbacks, and common questions to help you make an informed decision. Keep reading!
Materials Used in Metal Roofing
Steel
Steel is one of the most common materials for commercial metal roofing. It’s durable, corrosion-resistant (especially when coated with protective layers like zinc or aluminum), and cost-effective. Many property managers appreciate its strength and longevity, making it ideal for large buildings.
Pros:
- Strong and durable
- Cost-effective
- Corrosion-resistant
Cons:
- Can rust if uncoated
- Heavier than aluminum
Aluminum
Aluminum is another popular pick because it is lightweight yet strong. It’s naturally resistant to rust and corrosion, which is perfect for properties in coastal areas where saltwater can be a concern. While it’s more expensive than steel, its durability often justifies the cost.
Pros:
- Lightweight
- Rust-resistant
- Coastal-friendly
Cons:
- More expensive
- Can dent easily
Copper
Copper roofing offers a unique aesthetic appeal and exceptional durability. Over time, copper develops a green patina that adds character to buildings. However, it’s one of the most expensive options, and its softness can make it prone to denting.
Pros:
- Long-lasting
- Attractive patina
- Low maintenance
Cons:
- Very expensive
- Prone to dents
Zinc
Zinc is known for its self-healing properties; scratches and minor damages naturally repair themselves over time. It’s also highly sustainable and recyclable. Like copper, zinc is on the higher end of the price spectrum but offers impressive longevity and low maintenance.
Pros:
- Self-healing
- Sustainable
- Low maintenance
Cons:
- High cost
- Requires skilled installation
Types of Metal Roofing
Corrugated Metal
Corrugated metal roofing sheets are characterized by their wavy pattern, which adds strength and durability. They’re economical and easy to install, making them a favorite for various commercial applications. The design ensures effective water runoff, reducing the risk of leaks.
Standing Seam
Standing seam metal roofing systems feature long, vertical panels with seams that rise above the flat surface. This design provides superior weather resistance and a sleek, modern look. Although standing seam roofs are more expensive and complex to install, they offer excellent long-term performance.
Pros of Metal Roofing
- Durability: Metal roofs can last 40-70 years, outlasting other materials like asphalt shingles.
- Low Maintenance: They require minimal maintenance, saving time and money in the long run.
- Environmentally Friendly: Most metal roofs are made from recycled materials and may be recycled again at the end of their life.
- Fire Resistance: Metal roofs are non-combustible and provide excellent protection against fire.
Cons of Metal Roofing
- Cost: The initial cost of metal roofing is higher compared to traditional materials.
- Noise: Rain and hail can create noise, although insulation can mitigate this issue.
- Denting: While materials like steel are very durable, softer metals like copper and aluminum can dent under heavy impact.
- Complex Installation: Installing metal roofing requires specialized skills, which can add to labor costs.
Frequently Asked Questions
Why is Metal Roofing Said to Be Energy Efficient?
Metal roofs reflect a significant portion of solar radiation, reducing the heat that enters the building. This can lead to lower cooling costs, especially during hot summers.
Should Metal Roofing Be Used on a Flat Roof?
It’s generally not recommended to use metal roofing on flat roofs. Metal roofing systems are designed to shed water efficiently, and flat roofs don’t provide the necessary slope for proper drainage.
Does Metal Roofing Attract Lightning Strikes?
No, metal roofing does not attract lightning. In fact, it is less likely to ignite from a lightning strike than other roofing materials because it is non-combustible.
Are Metal Roofing Panels More Prone to Hail Damage?
While metal roofs can dent from large hailstones, they are generally more resistant to severe damage. Choosing a thicker gauge can help minimize the risk.
What Is the Best Underlayment for a Metal Roof?
The best underlayment for a metal roof is typically a high-temperature synthetic material that can withstand the metal’s expansion and contraction. This method helps ensure moisture protection and longevity.
How Should I Measure a Roof for Metal Roofing?
To measure a roof for metal roofing:
- Measure the length and width of each section.
- Multiply these dimensions to get the area.
- For complex roofs, break the roof into smaller sections, measure each section, and then add the totals together.
- Always account for overhangs and waste by adding an extra 10-15% to your measurements.
