Should You Opt for Corrugated Metal Roofs? Discover the Pros and Cons

Hello homeowners! Do you want to kickstart your roofing project but can’t decide on the ideal roofing material? Well, when it comes to selecting the best material for your roofing and siding needs, the multitude of options can make your head spin. Even when you’ve settled on using metal, there’s still a spectrum of choices to navigate. Among the top contenders in the metal panel arena are the ever-popular corrugated sheets. 

In this blog, we’ll delve into the pros and cons of corrugated metal roofings, helping you determine if they’re the perfect fit for your project.

An Overview of the Corrugated Metal Roofing Systems :

Corrugated roofing has enjoyed a long-standing presence in the construction industry. Those distinctive undulating panels not only make an aesthetic statement but also deliver durability and strength. Initially relegated to industrial spaces like warehouses and barns, corrugated metal roofs are now widely used for residential homes.

This unconventional roofing style isn’t just about appearances; it bestows an extra layer of sturdiness, making it a sensible option for a variety of architectural styles and even the harshest weather conditions.

Exploring the Types of Corrugated Metal Panels:

Corrugated metal panels are made of rippled metal sheets, a material that’s rigid yet remarkably lightweight and boasts water-resistant properties. These panels find their place in roofing, flooring, and siding, with frequent applications in houses, storage facilities, mass-production plants, and farms. The variations among corrugated metal panels primarily hinge on their gauge and board size, and the palette of colours is extensive, ranging from smooth to stucco patterns.

The Pros of Corrugated Metal Roofs: 

It’s little wonder that many homeowners have turned to this unique roofing style for their dwellings. The benefits of corrugated metal roofs are plentiful-

  • Exceptional Longevity:

    Corrugated metal roofs are renowned for their endurance, with a lifespan exceeding 50 years. They stand firm against the onslaught of strong winds, heavy rain, snow, and hail, outperforming conventional shingle roofs. Moreover, the application of a protective metal roof coating further bolsters their resistance to rust without necessitating major repairs or replacement.

  • Low Maintenance: In contrast to the upkeep required for asphalt shingles and wooden shakes, corrugated metal roofing systems demand minimal maintenance. Routine inspections and occasional cleaning suffice to keep them in excellent condition, rendering them a cost-effective choice in the long run.

  • Energy Efficiency: All metal roofs, including corrugated ones, excel in energy efficiency. They provide effective insulation and can be coated with reflective materials. These features bolster their ability to keep extreme temperatures at bay, enabling HVAC systems to work efficiently without consuming excessive energy or running around the clock. The result? Lower utility bills.

  • Cost-Effective: Corrugated metal roofs generally cost less than their smooth-standing seam counterparts. For those seeking the benefits of metal roofing without a hefty price tag, these wavy panels offer the perfect option. While their initial cost may exceed that of asphalt shingles, their enduring value positions them as the more economical choice over time.

  • Lightweight Construction: Corrugated sheets are surprisingly lightweight compared to other types of metal roofs. This characteristic not only simplifies and expedites the installation process but also ensures that the roof’s weight doesn’t impose undue stress on your home’s structure.

  • A Spectrum of Designs and Colours: Corrugated metal roofs don’t just offer strength and resilience; they bring style to the table. With a wide array of designs and colours at your disposal, you can make a statement that mirrors your personality and complements your home’s aesthetic. Who says metal roofs can’t be fashionable?

    The Cons of Corrugated Metal Roofs:

    Although corrugated metal roofs have numerous advantages, these roofs have the following downsides-
  • Exposed Fasteners: The primary issue with corrugated metal roofs lies in their exposed fasteners. Each fastener that penetrates the panel presents a potential weak point, and corrugated panels may require a significant number of fasteners to hold them in place. If not properly installed or if they become loose, these fasteners can render the roof susceptible to leaks.

  • Frequent Inspection: The reason why you should regularly inspect your metal panel siding and roofing, especially following severe weather events, stems from the exposed fasteners. Timely inspection can potentially save you from more extensive problems down the road.

  • Not Suitable for Flat Roofs: It’s strongly advised not to install corrugated metal roofing on flat surfaces, primarily due to the lack of a steep pitch for rainwater runoff. This deficiency can lead to issues with the exposed fasteners, making leaks more likely and potentially necessitating costly roof renovations.

  • Susceptibility to Distortion and Leaks: Corrugated sheets can become distorted under the influence of fluctuating temperatures. What this means is that they expand and contract with temperature changes, which can cause the fastening system to loosen and distort the panel surface.

  • Panel Sidelap and Corrugated Panels: It’s important to note that corrugated panels result in a loss of square footage during installation due to the panel side lap, where two like panels overlap. While this might seem insignificant, it can accumulate into a significant issue depending on the project’s size.
