If your current roof has reached the end of its lifespan or you?re aiming for a more updated look, replacing it is a significant decision. Choosing the best roofing material requires evaluating all your options. With that in mind, let?s explore the benefits and drawbacks of installing a metal roof.
What Is Metal Roofing?
Metal roofing refers to a roof system constructed from metal components. These systems are typically installed as large panels or modular sections that are secured to your home?s structure. Common types of materials used for metal roofing include:
- Copper: A long-lasting, fully recyclable metal that resists rust and lightning strikes. It?s also one of the priciest metal roofing materials available.
- Steel: Galvanized steel, protected by a zinc layer and tough exterior coating, offers a cost-effective substitute for copper. Stainless steel is completely rust-resistant but costs more, while stone-coated steel is ideal for high-wind regions.
- Aluminum: Known for being lightweight and affordable, aluminum is resistant to corrosion and harsh weather but can be prone to dents.
- Zinc: With a lifespan that often exceeds 100 years, zinc is a budget-conscious and low-maintenance option.
- Tin: Often constructed using soft metals coated with tin or lead, this material was more common before asphalt shingles became widespread. Tin roofing is light, efficient, and easy to care for.
Newer composite metals?blends of steel, zinc, and aluminum like Zincalume?are becoming more popular for their increased durability and rust resistance.
The Upsides and Downsides of Metal Roofing
Metal roofing might be the perfect fit depending on your lifestyle, aesthetics, and budget. Below is a balanced look at what to expect from this roofing option.
Benefits of a Metal Roof
Metal roofing offers compelling reasons for homeowners to consider this material. Here are the standout advantages:
1. Exceptional Longevity
A metal roof is a lasting upgrade. When installed correctly, it can perform for 40 to 80 years or more. The exception is exposed fastener systems, which generally need replacing after 15 to 20 years.
2. Strong Warranties
Most manufacturers offer warranties ranging from 30 to 50 years?surpassing the lifespan of typical asphalt roofing, which averages between 20 and 50 years.
3. Superior Strength
Metal roofing is built to handle extreme weather, fire, salty air, and wind gusts up to 140 mph. Special coatings prevent rust and cracks. If the finish wears down over time, repainting is usually enough to restore it, which may also boost property value.
4. Eco-Friendly
Made with at least 25% recycled materials and fully recyclable when removed, metal roofs are a smart choice for sustainability.
5. Energy Efficiency
Though more expensive upfront than asphalt shingles, metal roofs reflect solar radiation instead of absorbing it, which helps reduce cooling expenses?potentially by up to 40%, per the Metal Roofing Alliance. This cooling benefit also helps reduce the urban heat island effect.
Even in cold climates, metal roofing provides insulation comparable to asphalt.
6. Versatile Design Options
Forget the outdated image of a barn-style roof. Metal roofing comes in many forms: standing seam panels, corrugated sheets, and even styles that mimic wood shake, slate, or clay tiles. Finishes and color options are vast, especially with steel and aluminum, which hold paint exceptionally well.
7. Enhanced Curb Appeal
Metal roofing adds a sleek, modern appearance that can elevate your home?s look. It also attracts buyers due to its durability and minimal maintenance. Plus, metal roofs can be repainted to match changing styles, increasing resale appeal.
Drawbacks of Metal Roofs
While metal roofing comes with many perks, there are a few potential downsides:
1. Higher Upfront Cost
Switching from asphalt to metal roofing comes with a steeper price. Installation costs range from $8,500 to $130,000, averaging around $13,200?well above asphalt?s $5,000 to $12,000 range. Still, the long-term benefits could outweigh the initial expense, including potential insurance discounts.
2. Susceptibility to Dents
Some metals, like aluminum and copper, can be dented by hail or fallen debris. These softer materials may not support foot traffic either.
3. Sound Transmission
If you don?t enjoy the sound of rain tapping on metal, you may find this roofing style too noisy. Additional insulation layers can help quiet the noise, however.
4. Difficult Repairs
Although it?s tough to damage a metal roof, making repairs can be more complex than with shingles. Metal expands and contracts with temperature changes, which can affect how patches hold. Repairs average around $1,700?about double the cost of fixing asphalt shingles.
5. Risk of Rust
Inadequately coated metal panels may corrode, especially in salty environments. While galvanized steel is vulnerable, materials like aluminum, stainless steel, and copper are more resistant to rust.
Metal Roof Alternatives
If you?re unsure about committing to a metal roof, consider these other common roofing materials:
- Asphalt Shingles: A cost-effective option lasting 15 to 30 years.
- Tile: Offers high-end appearance and durability, with a price to match.
- Flat Roofing: Includes rubber, tar and gravel, and synthetic membranes.
- Slate: A premium, elegant option with a heavy weight and higher installation cost.
Is Metal Roofing Right for Your House?
Ask yourself if the long-term savings of a metal roof justify the upfront price. If you plan to stay in your home for decades, it may be worth the investment. However, short-term homeowners or those on tight budgets may find traditional materials more practical.
Also, verify with your HOA (if applicable) before moving forward?some neighborhoods restrict the use of metal roofing.
A properly installed metal roof offers solid protection and excellent value, but choosing an experienced local installer is essential. A poor installation can lead to leaks and major repair costs.
Frequently Asked Questions
Do metal roofs make homes hotter?
No. Metal roofs reflect sunlight, helping to keep your home cool. Metal?s quick heat transfer allows it to shed heat rather than retain it.
Are metal roofs noisy during rain?
They can be, but with proper insulation and underlayment, noise levels are comparable to asphalt. Some metal roof types are designed to reduce sound.
How long will a metal roof last?
With proper care, a metal roof can last anywhere from 40 to 80 years. Durability varies based on the material, attachment method, and climate.
