What is a Standing Seam Metal Roof?
A standing seam metal roof is a type of metal roofing panel that mechanically locks together with the other metal panels and uses concealed fasteners.
Standing seam metal roofs can be recognized by having a raised (or standing) seam. These rise up over the flat area of the panel in a long line.
Standing seam material can be used on metal roofs, but it can also be used on metal walls, though standing seam metal roofs are much more common.
The most notable thing to keep in mind when it comes to standing seam metal roofs is that the fastener is hidden under that raised seam.
The panel is attached with a clip directly to the roof decking underneath the standing seam leg making the fasteners hidden.
What is a Corrugated Metal Roof?
A corrugated metal roof is a roll-formed piece of metal sheet that’s formed into a metal roofing panel, and it’s typically rounded and wavy.
The term “corrugated” can be a tricky one since people in the roofing industry use it to refer to the wavy, “S” shaped roofing panel, or anything rounded and wavy but not squared off and boxy.
The term itself, however, means any type of metal that has grooves and ridges (which would include squared-off and boxy shapes).
Corrugated metal roofing is a lightweight, low-cost, but durable roofing type that is easy to install and makes for a great replacement over typical asphalt shingles. Corrugated metal roofing is used in both commercial and residential buildings, and it can be used as metal roofing or metal walls.
What are the Differences Between Standing Seam and Corrugated Metal Roofs?
Cost
The cost comparison of standing seam and corrugated metal roofs is pretty substantial. While the ultimate cost depends on the size and complexity of your roof, corrugated metal roofs are more expensive than asphalt shingle roofing and standing seam metal roofs cost up to twice as much as corrugated metal roofs.
Installation
Standing seam metal roofs are very complicated to install and can be a labor-intensive process. Their hidden fasteners make it a weather-tight roof, but a skilled hand by a professional roofing contractor is required for the job to be properly done.
Corrugated metal roofs have exposed fasteners, and while this makes the installation process much easier, faster, and cheaper (the roofing panels can be quickly screwed on and don’t have a complicated standing seam), they are more prone to leaks due to this type of installation.
Durability
All metal roofing types are well-known for their durability as long as they are properly maintained, Metal roofs hold up to weather and time much better than many other roofing types, especially asphalt shingles. That being said, not all roofing types are created equal and some are much more durable than others.
Standing seam metal roofs have a hidden fastener allowing them to be more durable and less prone to leaks, rust, and uplift from high winds than corrugated metal roofs.
Appearance
Standing seam metal roofs have a smooth, modern design. They’re flat except for the long, vertical standing seams that run up and down the roof, and they can come in a variety of colors. Corrugated metal roofs are wavy and will have exposed fasteners. They can also come in a variety of colors.
