Corrugated Metal Roofing v. Standing Seam (Pros & Cons)
The two most popular metal panels are corrugated and standing seam. A corrugated metal roof consists of a formed metal sheet with alternating curved and wavy ribs. The edges of each panel overlap and are fastened together. It’s an exposed fastener panel which means the fasteners penetrate the panel.
Standing seam metal roofing consist of a formed metal sheet with vertical ribs at panel edges, installed by lapping and interlocking edges of adjacent panels. The panels are attached to the substrate using concealed clips and fasteners. The screws don’t penetrate the panel.
Corrugated Metal Roofing Pros:
1. Cost - Corrugated metal roofing panels cost half as much as standing seam.
2. Fast And Affordable Installation - Requires less of a skillset, Easier install vs standing seam.
3. Less Prone to Visible Oil Canning
Corrugated Metal Roofing Cons:
1. Weather Tightness - It's an Exposed fastener panel. This means that thousands of fasteners penetrate the panel to keep the roof in place. All of these penetrations in the roof leave a chance for moisture to get in. If the fasteners are not properly installed or become loose, the roof can be vulnerable to leaks.
2. Additional maintenance vs standing seam
3. Corrugated metal roofing requires a minimum roof slope of 3” in 12”.
Standing Seam Metal Roofing Pros:
1. Aesthetics - Standing seam is streamlined and has a modern appearance.
2. Less Likely to Leak - It's a concealed fastener panel which means the fasteners don’t penetrate the metal roofing panel.
3. Suitable For Low Slope Roofs - Mechanically fastened standing seam panels are suitable for roof pitches of 1” in 12” or greater.
Standing Seam Metal Roofing Cons:
1. Cost - Standing seam metal roofing panels can cost twice as much vs corrugated panels.
2. Installation - Standing seam is difficult to install. It's not a DIY friendly panel and the installation cost are 30%-50% more vs corrugated.
3. Requires more metal roofing flashing - The cost of the metal roofing trim will be at least 50% more vs corrugated.
