Corrugated & Ribbed Metal Roofing Cost, and Pros & Cons 2021

Corrugated metal roofing and its close cousin, ribbed panel roofing, offer the original style of corrugated (iron) steel roofs. At an average cost of $4.50 to $8.50 per square foot installed, corrugated metal is priced somewhat similarly to asphalt shingles, especially at the low end, and yet, high-end corrugated metal panels are far more durable, energy efficient, and can last far longer than asphalt shingles.

What Exactly Is Corrugated and Ribbed Metal Paneling?

Sheet metal coil (typically galvanized steel or aluminum) gets fed into a roll-forming machine that shapes the metal sheet into the curvy U-shaped, wavy pattern — the primary variation for corrugated metal roof and wall panels.

Corrugation gives metal panels considerable structural strength, which makes it possible to use these otherwise thin sheet metal panels for building envelope applications, such as roofing and cladding.

Old School Corrugated Steel Panels

During the height of the Industrial Age, steel became relatively cheap and abundant. Metal was viewed as the kind of material that offers an economically viable way to cover the roofs on large agricultural and industrial buildings. Back then, the corrugated steel panels were often non-coated, but that was not a problem since there were plenty of spare steel roofing and wall panels to replace any corroded ones as needed.

As steel corrodes, it develops visible rust. When the old steel panels would get too unsightly or worse yet, develop holes resulting in leaks, they would get replaced with the shiny new pieces.

Today, corrugated metal panels are often chosen because of their old school appearance and relatively low cost compared to standing seam and architectural metal shingles and tiles.

Most modern corrugated steel panels are normally coated with a galvanic (zinc) self-healing zinc coating to prevent oxidation and corrosion, and thus made to last for decades, especially when finished with a high-end Kynar 500 factory applied paint finish.

Metal Siding Options, Costs and Pros & Cons in 2021

Residential metal siding offers five primary choices of materials: G-90 Galvanized steel, Galvalume coated steel, aluminum, zinc, and copper. Steel and Aluminum are the predominant choices when it comes to metal wall cladding systems available for residential and commercial projects.

Zinc wall panels are considerably more expensive, but they are also more durable and longer lasting compared to steel and aluminum. Zinc panels are typically used in high-end commercial metal wall projects and roofing applications.

Copper is the more exotic and most expensive metal that can also be used in roofing and metal wall cladding applications. However, copper is rarely used as a siding material due to its high cost and highly reflective surface, which makes it far more suitable for roofing

Thanks to the remarkable durability and versatility of metal, the panels can be shaped as corrugated or ribbed, or made to mimic lap siding or vertical boards. However, metal siding doesn’t attempt to mimic stucco, stone or brick siding, as these generally constitute unique shapes.

Cost

Residential metal siding panels can range in cost between $8.00 to $25.00 per sq. ft. installed, depending on the metal panel profile, material, project complexity, and your home’s location.

  • Architectural grade steel panels including G-90 Steel and Galvalume steel with Kynar 500 paint finish can typically be installed for $8.00 to 12.50 per sq. ft.
  • Aluminum siding with Kynar 500 paint finish can typically be installed for $8.50 to $13.50 per sq. ft.
  • Zinc cladding and zinc wall panels can typically be installed for around $12.00 to $20.00 per sq. ft.
  • Copper is the least common and most expensive metal siding option that can be priced as high as $20.00 to $35.00 per sq. ft. installed.

For a metal siding installation on a house, it is strongly recommended you go with a professional and experienced contractor. For smaller projects, such as a shed or garage, the DIY approach is feasible.

On larger projects, where pieces are cut to cover either larger areas or unique layouts, a professional will not only work faster but be more careful. Metal is malleable which if not careful can lead to waste of purchased materials. Plus, metal installation can be somewhat dangerous with its sharp edges.
