Due to its strength and visual characteristics, the demand for metal roofing has increased in the past few years. According to the Dodge Report, the popularity of this roofing option has increased during the years 2019 to 2021 from 12% to 17%. This type of roofing is characterized by unique wavy patterns, but there are many more advantages it provides to make it an appealing and practical option for residential and commercial properties. Here, in this guide, we will look at the upsides of corrugated metal roofing, share some tips for its installation, and finally let you know how to choose the right corrugated metal roofing for your space.
What Is Corrugated Metal Roofing?
This type of roofing involves metal sheets rolled to form metal panels which are secured to the roof through screws. These panels are known as exposed fasteners panels, because the fasteners are visible on the surface.
Corrugated metal roofing serves as a great alternative to asphalt shingles or clay tile roofs. Despite these roofs being relatively new to the construction industry, they have many useful aspects. These materials are not only stylish, but they are also durable, long lasting, and can withstand harsh weather conditions. Moreover, they are lightweight, affordable, energy efficient, and can be installed without much fuss.
Additionally, it is available in 3 types: ⅞” corrugated, ½” corrugated, and other variations like ribbed metal roofing panels. This roofing material is exceptionally strong and can also be used in a variety of different residential and commercial projects for siding or roofing.
Origin and Manufacturing Process of Corrugated Steel
Henry Robinson Palmer invented corrugated steel around the 1820s for construction purposes. While employed at the London Dock Company, Palmer designed corrugated steel panels that could be quickly installed by workers with little or no construction experience. Because it was inexpensive and prefabricated, it became an overnight sensation.
But have you ever thought about how the unique shape of corrugated steel came into existence? Well, the forming of the panel involves the shaping of metal sheets in roll-form. The sheet metal is pulled out from large round metal coils and is passed through the rolling dies to achieve the desired shape. Once the sheets have passed through all the rollers, they are cut into panels of specific dimensions.
Benefits of Corrugated Metal Roofing
Here are the following benefits of using corrugated metal roofing for which every homeowner should opt for it:
- Durability: If given proper care and maintenance and if protected from erosion, metal roofs can last more than forty years.
- Weather Resistance: The roofing is suitable for different climate conditions because it is able to withstand powerful winds, heavy downpour and snow.
- Low Maintenance: The only care needed is the occasional recoating and readjustment of the fasteners.
- Energy Efficiency: It reflects sunlight therefore cutting on the costs of cooling. Some of the panels also have reflective coatings that make them very efficient.
- Lightweight: When comparing the weight of the roof with that of a normal roof, it can be seen that the process of installation is much easier.
- Eco-Friendly: Metals are considerably efficient for construction purposes as they are highly recyclable and contribute towards ecological sustainability.
- Fire Resistance: They are non-combustible due to Class A fire rating. You can add flame-retardant on them for further fire protection measures.
Choosing the Right Corrugated Metal Roofing
To ensure that the corrugated metal roofing is right for your home, consider looking into different types of panels, material options, gauge, color, and finish.
Panel Types
When deciding on the type of panel for your corrugated metal roofing, it is advisable to think of the strengths and aesthetically covering elements required. The most common option, the ⅞” corrugated panel, is highly demanded due to its strength and offering a wide coverage of about 34.67 inches. It is perfect for both residential and commercial use. Alternatively, the ½” corrugated panel has a lower profile, providing coverage of approximately 21.33 inches. The roofing projects where cost and weight are significant aspects, these panels are purchased.
Material Options
There are many options of material available, and each comes with its own set of advantages. One of the material options available is galvanized steel that is widely used due to its ability to resist corrosion, along with being durable and cost effective. Another option is Galvalume® coated steel which offers a better level of protection against corrosion and is ideal for areas with extreme weather conditions. Lastly, people residing in coastal regions use aluminum due to its lightweight nature and corrosion resistant tendencies.
Selecting the Appropriate Gauge
The term ‘gauge’ used in metal work refers to the thickness of the material which in turn correlates with the strength and durability. Depending on the manufacturer, corrugated roofing materials can be found in gauges ranging between 22 and 29, with 29 being considered the thinnest. The correct gauge choice depends on factors such as climate, budget, and the structural requirements of the roof. Heavier gauges make the metal roofing more robust which is recommended for places that have severe weather conditions and heavy snowfall.
Color and Finish Considerations
The color or finish that you choose for your corrugated metal roof will tell you how your house will look as well as it will dictate the energy efficiency. Light colors reflect sunlight, reducing the cooling costs, whereas dark colors tend to cause higher cooling costs due to high heat absorption, but the upside is they are warmer in the winter. If a traditional style is more of your taste, then a matte finish would best suit you but if you are looking for something more contemporary, then a glossy finish would work better. Select a color and finish that will complement your home’s style and is suitable according to your geographical location.
Final Thoughts
In conclusion, it can be stated that corrugated metal roofing is a perfect solution for those who need affordable, durable, and long-lasting roofing. This is because it is light weight hence the cost of installation and repair will be relatively low. Being available in different colors and styles, it is able to meet the diverse needs of the consumers. This material does not corrode; hence, it can be used in areas with extreme weather conditions. It also has energy saving features hence reducing the energy cost due to the use of cooling systems. If you want the corrugated metal roof to last longer, it is advisable to hire a professional contractor for proper installation and ensure that you periodically check the roofs and maintain them properly.
FAQs
How long does a corrugated metal roof last?
If well maintained, a corrugated metal roof should last for at least 30–45 years. But with most care, such as frequent inspections, regular maintenance and timely treatments, the life span of such a roof can be over 50-60 years.
Is corrugated metal roofing noisy during rain?
Some people may find the sound of rain over a metal roof pleasant, however, others might feel quite the opposite. To ensure a less noisy experience, insulation can help as it dampens the noise when there is heavy rainfall.
Can I install corrugated metal roofing myself?
Yes, you can install a corrugated metal roofing yourself if you have the skills and experience. However, it is recommended to hire a professional installer to ensure that all seams are properly sealed and that the entire structure is weatherproofed to make the roof less prone to leaks and damage, thus increasing the longevity of the roof.
What maintenance does corrugated metal roofing require?
A corrugated metal roof will require cleaning and maintenance at least twice a year to look for signs of rust and wear, and removal of dirt and dust that could serve as a source of corrosion. Make sure that gutters are clear and large overhanging tree branches are trimmed to avoid moisture buildup. Fix any visible scratches or leaks and consider regular professional inspections for the best upkeep of the roof.
