Metal roofing has gained significant popularity as a durable and long-lasting alternative to traditional roofing materials. It has impacted both residential and commercial construction, offering a combination of aesthetics and functionality. This roofing option affects energy efficiency, maintenance requirements, and overall property value.
In this blog, we’ll explore various aspects of metal roofing to provide a comprehensive understanding. It examines available material types, cost factors, primary benefits, and potential challenges. We’ll also address common metal roofing misconceptions, and installation considerations as well as compare metal roofs with other roofing solutions like shingles.
Types of Metal Roofing Materials
There are various types of roofing materials, each with its unique qualities and benefits. The most common types include steel, aluminum, copper, and zinc. Each material has its advantages and for homeowners, it all trickles down to what best suits their preferences, needs, climate, and budget.
Steel Roofs
Steel roofs are the most popular metal roofs. It’s widely used for its strength, durability, and affordability. Steel roofing panels come in different forms; for example, Galvalume and galvanized steel. Galvalume is made up of 55% aluminum, 43.4% zinc, and 1.6% silicone and is more durable than galvanized steel. Steel roofing options include corrugated metal panels, which are more affordable, and standing seam panels, which offer maximum weather resistance and a clean, modern look.
Aluminum Roofs
Aluminum roofing is lightweight but strong, which makes it a good choice for different applications. Compared to other roofing materials, Aluminum roofs have the highest strength-to-weight ratio and are particularly suitable for coastal environments because they dust rust easily. The reflective properties of aluminum roofs help keep houses cooler during the summer heat and that can potentially reduce energy costs by up to 20%.
Copper Roofs
Copper roofing is a premium option known for its unique appearance and long life. Copper roofs are usually reddish-brown but develop a green patina over time, which is what some homeowners love. Copper roofs are durable, lasting up to 100 years or more, and have antimicrobial properties that prevent algae and moss growth. The only drawback is that copper roofs are quite expensive, ranging from $14 to $30 per square foot.
Zinc Roofs
Zinc roofs are not quite common in the United States. They offer a uniquely beautiful look, starting with a dark gray color and developing a blue-gray patina over time. Zinc roofs are fairly durable, with some having a lifespan of 80-100 years. They also are quite eco-friendly and 100% recyclable. Zinc roofing costs range from $6 to $12 per square foot.
Cost Factors for Metal Roofs
If you plan to install a metal roof, it is important to understand the factors that will influence the cost of the entire project.
Cost of Materials
The type of metal you ultimately decide on will affect the total cost of your roofing. Steel roofs are the most preferred option as it’s durable and affordable with prices ranging from $6 to $16 per square foot. Aluminum roofs are also quite affordable at $4 – $11 per square foot and are preferred by homeowners looking for lightweight roofs. For homeowners who prioritize durability, copper can be a decent choice but will cost you between $15 to $30 per square foot.
Work and Installation
Roofing workmanship costs will be a big part of the total cost of installing a new roof. Metal roof installation costs around $3 – $12 per square foot but the prices may vary depending on the city you’re in or the time of the year. Also, the complexity of roof design can affect the final installation cost.
Size and Complexity of Roof
The size of your roof and the complexity of the design will significantly affect how much you spend. Roofs that cover a larger area will need more materials and work, so they will likely cost more. Complex roof designs, such as those with steep slopes or numerous chimneys, could drive up both labor and material costs.
Geographic location
Your home’s location significantly affects the cost of a metal roof. In areas where severe weather is common, the cost tends to be higher because homeowners seek more durable roofing materials. Additionally, in regions with a high cost of living, professional roofers may charge more, which increases the overall installation cost. It’s advisable to research the costs in your area and consider the local weather conditions that might necessitate additional materials or a specific type of metal roof.
Main Benefits of Metal Roofing
Metal roofing has become a popular choice for people who want durable roofs, energy savings, and environmental friendliness. This section addresses the main reasons why metal roofs are a smart choice, and why so many people opt for this option for their homes and commercial buildings.
Longevity and durability
One major reason why people prefer metal roofs is their durability. Depending on the type of metal, these roofs can last from 40 to 80 years, far exceeding the typical 20-year lifespan of asphalt shingle roofs. This means that for many homeowners, the metal roof they purchase will be the last roof they’ll ever need.
Metal roofs can withstand various weather stresses, including strong winds, heavy snow loads, and even fire. They can resist winds blowing at up to 140 miles per hour and have a Class A fire rating, making them a suitable choice for various climate conditions. Due to their durability, metal roofs require less frequent repairs or replacements, which saves homeowners both money and time over the long term.
Energy efficiency
Metal roofs significantly impact a home’s energy efficiency. They can help homeowners save up to 40% on energy costs by reflecting solar heat, which keeps the house cool and reduces expenditure on cooling systems. Even when painted to match the house color, metal roofs still reflect sunlight, decreasing solar heat gain during hot seasons.
A study conducted by R&D Engineering demonstrates that stone-coated metal roofing products can increase a home’s energy efficiency by 218% compared to standard 3-tab asphalt shingle roofs. This remarkable energy-saving characteristic makes metal roofs an excellent choice for homeowners who aim to reduce their environmental impact and lower their energy bills.
Fire resistance
Even though metal roofs are not completely fireproof, they resist fire better than many other roofing materials. Most metal roofing materials are non-combustible, with steel being a popular choice due to its high melting point. Aluminum, copper, and zinc also exhibit excellent fire resistance, contributing to overall building safety. This quality is particularly crucial in areas prone to wildfires or for homeowners seeking additional protection for their property.
Eco-friendliness
Metal roofs are a good choice for people who care about the environment for many reasons. They often use recycled materials to make these steel roofs, and they can be recycled, which reduces the need for new materials and reduces waste that ends up in landfills. This is very important to homeowners who want to reduce their negative impact on the environment.
Since metal roofs are durable, it means that a person doesn’t need to replace them often, which also helps reduce waste. Because metal roofing is lightweight, it can often be installed over an existing roof, which means that you don’t need to remove and dispose of old roofing materials.
Potential Drawbacks of Metal Roofing
Even though metal roofing has a lot of advantages, it is important to consider the possible issues that can arise from it before a person decides. If a person understands these factors, it would help homeowners make better choices about whether metal roofing is the ideal option for their 1,500 sq ft house or other buildings.
Higher upfront costs
One of the biggest concerns that potential metal roof customers face is the initial cost. Metal roofing materials, like steel, aluminum, and copper, are more expensive than traditional asphalt shingles. The cost of materials plus the labor needed to install them make metal roofs a significant investment. For example, a standing seam metal roof can cost between $10 – $16 per square foot, while a corrugated metal roof can range from $7 to $12 per square foot. Even though metal roofs save money in the long run because they are durable and energy-efficient, the upfront cost might be a challenge for some homeowners.
Noise concerns
Metal roofs can be noisier than other roofing materials, especially during heavy rainfall or hailstorms. Some people enjoy the sound of rain on metal roofs, while others find it disturbing. Light rain may sound like soft tapping or rustling leaves, but heavy rain can create an echo inside a house that sounds like a muffled drum roll. However, if installed properly, especially with solid decking and insulation, the noise levels can be significantly reduced.
Denting and color fading
Even though metal roofs are resilient, they can’t escape damage completely. Hail, falling branches, or other heavy objects that hit the roof may cause dents or scratches, especially with softer metals like aluminum or copper. Over time, the color of the metal roof may fade due to sun exposure and weather conditions. Fading occurs when water and chemicals in the air react with the paint, causing discoloration. The rate of fading depends on factors like UV light exposure, temperature fluctuations, and humidity levels.
Installation expertise required
To install a metal roof, people need special skills and knowledge. Not every roofing contractor has the experience or expertise needed to install metal roofs properly. If roofers do not install metal roofs correctly, it will cause issues like leaking, reduced energy efficiency, and even damage to the building. It’s important to hire reputable contractors who have proven expertise in installing metal roofing. Factors such as the complexity of the roofing project, local labor costs, and the contractor’s experience all affect the overall cost of the work. Typically, the cost of installation may account for 60% to 70% of the total cost of the roof.
Common Metal Roofing Myths
Lightning attraction misconceptions
Metal roofing doesn’t increase the chance of lightning strikes. It’s factors like the height of the building and its location that determine if lightning would strike, not the roofing material. In fact, metal roofs can help when lightning strikes. As it doesn’t combust and has the highest Class A fire resistance rating, metal roofs are one of the best options for houses in areas where lightning strikes are common.
Noise levels during rain and hail
Another rumor is that metal roofs make too much noise when rain or hail falls. The noise the rain makes will be determined by the type of metal roofing and how the roofers installed it. These days, professional metal roof installers like NearMe Roofing Company install metal roofs with solid sheathing and insulation that reduce noise significantly. Stone-coated metal roofing products are even a lot quieter because of the stone granules that absorb sound.
Rust and corrosion concerns
Even though some metals can rust, modern metal roofing materials are designed to resist rust and corrosion. Most professional roofers recommend galvanized steel, aluminum, and copper for metal roofs because they do better against rust. For example, DECRA Metal Roofing panels, a stone-coated steel manufacturer for roofing uses an alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon to ensure that they resist rust and corrosion for a long time. This formula combines the strength of steel with aluminum’s rust resistance to provide protection that lasts against adverse weather.
Considerations for Metal Roofing
When you want to install a metal roof, many important factors need to be considered to ensure that it performs well and lasts long. One of the main things to think about is the structural requirements. The roof substructure is like the foundation for the metal panels, and it must be able to support both live and dead loads. These loads include the weight of the roof materials, AC units, and external forces like wind, snow, and rain.
Proper ventilation and insulation are essential for metal roofs. If there isn’t enough ventilation, heat can accumulate in the attic, causing higher energy bills and prematurely damaging AC systems. Insulation helps prevent condensation inside, which can cause structural damage and mold growth if not managed properly.
Choosing a qualified contractor is crucial for a successful metal roof installation. Be sure to look for contractors who have been installing metal roofs for at least three years and ask them for a list of references.
Make sure the contractor has proper licensing and insurance, including general liability and worker’s compensation coverage. Warranty options are another important factor to consider. Reputable roofing contractors like NearMe Roofing Company offer a warranty that covers their workmanship.
Conclusion
Metal roofing has become a very attractive option for homeowners looking for durability, energy efficiency, and long-term value. From the different types of materials to the many benefits they offer, metal roofs provide a combination of functionality and beauty that can enhance any property. Even though the initial investment may be high, the long-term advantages usually outweigh the upfront costs. For people thinking of replacing their roofs or building a new house, metal roofing is something you should seriously consider.
Before you decide on whether metal roofing is right for you, it is important to weigh the pros and cons and consider your own needs and budget. Proper installation by experienced professionals is key to enjoying the benefits of your metal roof.
