Are Corrugated Metal Roofs a Viable Option for Homes?

Ever since the mid 1800s, corrugated steel panels have been used extensively on agricultural, commercial, and industrial roofs. You might remember the old barns and farm houses covered with those “ugly” U-shaped or ribbed steel panels. Many of those agricultural and industrial steel roofs would often have numerous rust spots and peeling paint as their signature mark.

In those early days, corrugated metal panels were typically made from bare, non-coated steel, which resulted in excessive corrosion, and hence bad reputation and perception of low quality. Nonetheless, steel was cheap and abundant material, which made it economically feasible to replace any old, corroded steel panels on an “as and when needed” basis. Such were the expectations and process at the time.


But what about today? Lets take a deeper look into what modern-day corrugated metal roofs are all about and whether or not they are suitable for residential applications.

Modern, corrugated metal roofing panels are primarily made out of galvanized steel (G-60 low-end, or G-90 better quality) in the form of U, V, R 5 V crimp and rib-shaped panels. Typically, they are employed as metal roof or wall system comprised of 32 to 36 inches wide corrugated panels held in place by exposed screws / fasteners color-matched to the paint color of the metal panels. Caulking is used at connecting points of overlap in between the panels for water tightness.

Various Metals, Affordability, and Maintenance Requirements

Corrugated metal panels can also be made from galvanized, galvalume, stainless steel, and aluminum. Normally, a corrugated metal panel does not have a lot of thickness in terms of metal grade, which makes it quite economical and hence affordable, but it may well require some maintenance every once in a while, including the exposed fasteners re-tightening and potential re-coating applications.

Corrosion Resistance & Panel Thickness

Modern corrugated metal panels offer superior corrosion-resistance, energy efficiency, and can provide an economical roofing and cladding solution for commercial, agricultural, industrial, and even residential uses. Corrugated metal panels are usually made from thin-gauge steel, usually a 29, or 26 gauge steel, which makes it economical and practical, when it comes to covering large areas of roofing surfaces. Corrugated metal roofs are more practical and longer lasting than asphalt shingle roofs, and they cost much less than standing seam or metal shingles.

Materials Pros & Cons:

standing-seam 1. Metal roofs can be made from a variety of metals and alloys including Galvanized steel — hot-dip zinc galvanized G-90 and G-60 steel (a less expensive thinner grade steel often used in low-cost corrugated metal panels), Galvalume steel — zinc and aluminum coated steel (A more expensive and longer lasting coating compared to G-90 steel.), stone-coated steel (G-90 galvanized steel), aluminum, copper, zinc, terne (zinc-tin alloy), and stainless steel.

2. The downside of galvanized steel (G-90, and especially G-60) is that it can corrode, eventually, especially when exposed to moist salt spray environment such as in close proximity to coastal areas.

3. Steel is the most frequently used material in both residential and commercial applications, mainly due to its lower cost.

4. Aluminum is the second most popular material. It is more durable and longer lasting than steel, but only costs a fraction of the price of premium metals, such as copper or zinc.
