Metal roofing panels are an incredibly popular roofing solution for residential, commercial, and industrial properties. They are cost-effective, durable, and provide excellent protection against the elements. But how do metal roofing panels work? In this blog, we’ll dive into the science behind these panels and explore why they’re such a popular roofing choice.

Composition of Metal Roofing Panels.

Metal roofing panels are typically made of steel, aluminum, copper, or zinc. These metals are chosen for their durability and strength, as well as their resistance to corrosion and rust. The panels come in a variety of shapes and sizes, including corrugated, standing seam, and ribbed profiles.

Corrugated metal panels consist of a series of ridges and valleys that give them their distinctive wavy appearance. The ridges increase the panel’s strength, making it more difficult to bend or break. Standing seam metal panels have interlocking seams that snap into place, creating a smooth, continuous surface. Ribbed metal panels, on the other hand, feature raised ribs that provide additional strength and stiffness.

How Metal Roofing Panels Work.

Metal roofing panels work by deflecting the elements and keeping water from seeping into your building. The panels are installed with a slight pitch to ensure that water flows off the surface, preventing pooling and leaks. This pitch is typically a minimum of 2:12 (2 inches of rise per 12 inches of run) but can be more in areas that receive heavy rainfall or snow.

One of the advantages of metal roofing panels is that they are very lightweight, making them easy to install. This means that the panels can be used in retrofit roofing projects, where the new roof is installed over the old one. This is not possible with other roofing materials, like concrete or tile, which are much heavier and require a full tear-off of the old roof before installation.

Metal roofing panels are also incredibly durable and long-lasting. They can last up to 50 years or more, depending on the type of metal used and the installation method. Metal is also resistant to fire, hail, and wind, making metal roofing panels an ideal choice for areas that experience severe weather conditions.

Benefits of Metal Roofing Panels.

There are several benefits to using metal roofing panels, including:

Energy efficiency: Metal roofing panels reflect heat from the sun, helping to keep your building cooler in the summer. This can reduce your energy bills by up to 20%.

Low maintenance: Metal roofing panels require very little maintenance, and any necessary repairs are easy to perform.

Eco-friendly: Metal roofing panels are recyclable, reducing waste and environmental impact. They are also energy-efficient, reducing your carbon footprint.

Versatility: Metal roofing panels come in a variety of styles and colors, allowing for customization to match your building’s aesthetic.

Cost-effective: Metal roofing panels are a cost-effective choice, as they last longer than other roofing materials and require less maintenance.


Metal roofing panels are an excellent roofing solution for any building, offering durability, strength, and energy efficiency. The panels work by deflecting the elements and preventing water from seeping into your building.
