rusted metal roof installed as siding. Although metal roofing systems are designed for longevity and durability,their use as siding is not typically recommended by professionals, and here's why.
Firstly, metal roofing and siding serve different purposes and have distinct design requirements. Roofing must withstand harsh weather conditions, while siding primarily protects against the elements and enhances aesthetics.
Why Metal Roofing isn't Ideal for Siding
The primary reason is that metal roofing systems are designed to efficiently drain water. They have wide seams and large holes for this purpose, which would be detrimental when used as siding.
Furthermore, metal roofing panels are not designed to overlap tightly like siding. This leaves gaps that can trap moisture and lead to structural issues over time.
Water Intrusion Risks
The large seams and gaps in metal roofs allow water to easily penetrate, which can cause serious damage to your home's structure when used as siding.
Moisture buildup can lead to mold, mildew, and rot, compromising your home's integrity. Additionally, the trapped water can freeze during winter, causing further damage due to expansion.
Heating and Cooling Inefficiency
Metal roofs can greatly increase the temperature of your home's attic, which in turn raises the indoor heat during summer. This can decrease your home's energy efficiency and increase cooling costs.
Conversely, in winter, this heat can escape quicker than it would with regular siding, leading to potential energy loss and increased heating costs. This can defeat the purpose of installing a new siding system.
Metal Roofing Material Types and Alternatives for Siding
Metal roofing comes in different materials like steel, aluminum, and copper. Each has its unique properties, but none are ideally suited for use as siding due to the reasons discussed above.
Instead, consider using metal siding products specifically designed for vertical or horizontal installation. These products often come in aluminum or steel, are lighter, and have tighter overlaps designed to combat water intrusion.
Aluminum Siding
Aluminum siding is lightweight, won't rust, and is low maintenance. It's also a practical and economical choice for home exterior siding.

Vertical or Horizontal Steel Siding
Steel siding, including vertical and horizontal profiles, offers excellent durability and resistance against denting and scratching.
