To start at the beginning, Pittsburgh corrugated metal roofing is an exposed fastener panel. This means that the screws will penetrate the roof panel when attaching to the plywood or metal substrate of your home. A substrate is the surface upon which the metal roofing or roofing underlayment is applied.
Visually, the appearance of a corrugated metal roof panel is wavy with “S” shaped curves. The term “corrugated metal panel” would not include a panel that is square or has a boxy appearance. In addition, the term typically refers to the two most common types of corrugated metal roofing: ⅞” Corrugated and ½” Corrugated.
How Do You Manufacture Corrugated Roofing?
Corrugated metal roofing starts as a large round coil of steel. The coil is put on a machine that will roll-form the corrugated roofing sheets. The metal starts as a flat piece of steel and then it passes through a series of rolling dies. Each of these rollers bends the steel until it comes out the end of the machine as a piece of corrugated metal.
Corrugated Metal Roofing Sizes: What Panel Lengths Are Available?
The length of corrugated roof panels can vary depending on where you are sourcing material. There are two ways to purchase roofing:
Home improvement stores
Companies such as Home Depot, Lowes, or lumber yards typically stock thin 29 gauge steel in only a galvanized or galvalume finish. If you decide to purchase corrugated metal roofing at Lowes, you’ll only find 10 or 12 foot lengths at the big box hardware stores.
If you only need a few sheets and need them quickly, this is a more efficient way to purchase corrugated sheet metal.
Manufacturer direct or metal roofing distributor
When ordering through a manufacturer or roofing distributor, corrugated metal roofing will be made to whatever gauge, colors, and panel lengths that your order requires. Typically, you will submit a materials list that will display the number of pieces needed and the sheet length for each piece. The metal roofing manufacturer will then produce your order per the cut list provided.
