Corrugated metal roofing systems are a go-to metal roofing option for both residential and commercial properties. As with any roofing material, there are both pros and cons to consider before making a decision. In this blog post, we’ll explore the benefits and potential drawbacks of corrugated metal roofs. Whether you’re building a new home or looking for a roof replacement, these facts will help you make an informed decision that fits your needs and budget.
Overview of Corrugated Metal Roofing Systems
A corrugated metal roofing system requires specific sheathing and underlayment. The roof covering is made up of metal sheets with a wavy pattern perfect for covering flat and low-sloped roofs. This gives it a unique look and provides additional strength and durability to the roof.
There are different types of corrugated metal roofing sheets and materials on the market, each with its own unique capabilities and attributes. Out of all of them, galvanized steel is the most common material for corrugated roofs. The term galvanized means that the steel has been coated with a layer of zinc to protect the steel from corrosion and rust, which prevents repairs and helps extend the roof’s lifespan.
How Corrugated Metal Roofs Can Benefit Homeowners
There are many different types of metal roofs, so why are corrugated panels so popular among homeowners? Let’s explore the benefits of this roofing system that attracts so many homeowners. From affordable costs to low maintenance, this roofing option has plenty of perks!
When it comes to roofing materials, durability is key. The last thing you want is to have to replace your roof prematurely due to damage from weather, pests, or other factors. Fortunately, a corrugated roof can protect your home for over 40 years!
This means you won’t have to worry about frequent repairs or replacements, saving you time and money in the long run. Additionally, corrugated sheets are resistant to cracking, warping, and shrinking, ensuring that your roof will stay in top condition for years to come.
In contrast, traditional asphalt shingles typically last between 15 to 25 years. This means that by choosing a corrugated metal roof, you’re making a wise investment in the long-term health and value of your home.
Furthermore, the longevity of this roof means that it’s an environmentally friendly choice, as it reduces the need for frequent replacements and the waste that comes with them.
#2 Energy Efficiency
Another advantage of the wavy metal roof design is its energy efficiency. Metal roofs are reflective, meaning they reflect the sun’s rays away from your home rather than absorbing them like traditional roofing materials. This can help reduce the amount of heat that enters your home during the summer, resulting in lower cooling costs.
Additionally, corrugated metal roofing systems can help retain heat during the winter, reducing your heating costs as well. According to the Metal Construction Association, metal roofing saves homeowners up to 40% in energy costs compared to traditional roofing materials.
#3 Fire Resistance
When it comes to fire safety, a metal roof is one of the safest roofing materials available. Unlike wood or asphalt, a metal roof is non-combustible, meaning it won’t catch fire or spread flames in the event of a fire. This can give homeowners peace of mind, particularly in areas prone to wildfires or lightning strikes. Additionally, metal roofing can help reduce the spread of flames from adjacent buildings, helping to protect your home in the event of a fire.
#4 Low Maintenance
One of the most appealing aspects of a corrugated metal roof is its low maintenance requirements. The roof is resistant to mold and algae that plague other roofing materials. This means that you won’t have to worry too much about cleaning and repairs.
The corrugations, or waves of these panels, provide excellent protection from wind uplift during stormy weather. The roof’s wind resistance is related to the panel thickness and the depth of the corrugations. While 26-gauge corrugated metal roofing sheets are the most common, 24-gauge sheets are even thicker and offer greater strength. This means that if you live in an area with harsh weather conditions, such as high wind or heavy snowfall, you’ll want 24-gauge panels.
#6 Cost Effectiveness
Corrugated sheets are more affordable compared to other roofing materials, including various metal panels. A standing seam metal roof has a higher cost per square foot due to its more complex installation process, which requires specialized equipment and expertise. In contrast, corrugated sheets are easy to install and can be done quickly and efficiently, reducing the labor cost to install corrugated metal roofing.
#7 Easy to Coat and Paint
It’s extremely easy to coat and paint corrugated metal sheets. There are lots of affordable metal roof coatings on the market, including acrylic, silicone, or polyurethane. These coatings have been developed to enhance the durability and weather resistance of a roof. If you want to change the look of your corrugated roof in the future, you can also paint it any color of your choice. Get the help of your metal roofing contractor to select the best paint for your corrugated metal roof.
This is especially useful for a homeowner who wants to customize the appearance of their roof to match the overall aesthetic of their home. With an additional protective coating, you won’t have to worry about repainting the sheets frequently or dealing with peeling or fading paint.
#8 Hide Dents and Scratches
When it comes to standing seam vs. corrugated metal roofs, the latter has a unique advantage. The waves on these sheets can help hide dents and scratches that develop due to hail, animals, walking, and other reasons. The ridges and valleys of the corrugated sheets help camouflage these cosmetic issues and maintain the appearance of the roof for longer. On the other hand, flat standing seam panels will show every scratch and dent in detail, requiring you to fix it.
While corrugated roofs offer many advantages, there are also some potential drawbacks to consider. Now we’ll dive into common concerns associated with this roofing system.
Potential Drawbacks of Corrugated Metal Roofing Systems
By understanding these common concerns and disadvantages, you can make an informed decision about whether this type of roof is right for your home, shed, or garage.
#1 Noise Level
One of the primary concerns with corrugated sheets is the potential for noise. They can be noisier than other types of roofing materials and metal panels, especially during rain or hailstorms. However, this can be mitigated by installing proper insulation.
#2 Difficulty With Solar Panel Installation
Compared to standing seam panels, it is relatively difficult to install solar panels on corrugated metal roofs. You need an expert to install solar panels on this roof using mounting systems specifically designed for corrugated roofs.
#3 Expansion and Contraction Issues
If you live in a hot region, corrugated roofing may not be the best option. The sheets tend to expand and contract with extreme temperature fluctuations, leading to warping or buckling.
#4 Difficult to Walk On
Walking on a corrugated roof can be challenging, especially when it’s wet or icy. This can make maintenance and repairs more challenging and potentially dangerous. But the good part is, it’s not costly to clean or maintain this roof, and you can easily find a reliable roofing contractor who’s experienced with corrugated metal roofs.
#5 Aesthetic Concerns
Some homeowners may be concerned about the appearance of a corrugated roof, as it can have a more industrial or functional look than aesthetic. However, there are many different styles and finishes to achieve a more traditional or decorative look. You can also go with a corrugated copper metal roof for a more luxurious and beautiful look!
#6 Debris Accumulation During the Fall
Another potential concern with corrugated roofing systems is the accumulation of debris during the fall. This can include leaves, pine needles, and other debris that become trapped in the ridges and valleys of the roof. Fortunately, metal roof cleaning is extremely affordable, and you just need to clean it twice a year (during the fall and after winter).
Once you’ve weighed the pros and cons of corrugated metal roofs, it’s crucial to take into account these key factors when making your decision.
What To Consider Before Choosing a Roofing System
First and foremost, it’s essential to consider your local climate. If you live in a rainy or snowy area, you may want to consider a material that better withstands moisture and has a high weight capacity, such as thick metal panels and sheets.
- The design and structure of your building can also influence the roofing material you choose. For a steep roof, choose a lightweight and easy-to-install roofing material.
- Corrugated metal roofing systems are generally cost-effective, but the total cost varies based on the quality of the roofing materials you use and aspects of maintenance.
Considering these factors will help you choose the right roofing system to fit your needs and meet your expectations.
