Choose Chatham High-Quality Corrugated Metal Roof

To understand corrugated metal roofing better, it helps to understand what “corrugated” means. Corrugated means “to be shaped into alternate ridges and grooves.” Essentially, that is corrugated metal roofing – metal sheets that are shaped with a pattern of ridges, typically a u-shaped pattern. Corrugated metal is made by taking sheet metal coil, usually galvanized steel or aluminium, and having a roll-forming machine shape the panels into the set corrugated pattern.

Three are several styles and patterns available, but the foundation is the same: The design of corrugated metal roofing gives better structural strength when compared to a flat panel. This allows a thinner piece of metal to have more strength and durability, which reduces the overall cost.

Most corrugated metal sheets are 2-3 feet wide, and they overlap on their outside curved portion. Fasteners are then driven through this point of overlap into the roof deck. Driving the fastener through the overlap not only keeps them fastened to the roof, but it also helps keep the metal panels from shifting and losing their overlap.

Reasons To Use Corrugated Metal Roof

  • Low cost: Corrugated metal is one of the cheapest metal roofing products available. It is also relatively inexpensive to install, especially on large areas, due to the long metal sheets used. Cost is a significant factor as to why corrugated metal is a popular roofing option.

  • Efficient: Because it is metal and can be painted, corrugated metal can be developed to reflect a lot of sunlight and heat. Similar to the standing seam, this makes it beneficial for large commercial buildings.

  • Durable: Due to the corrugation of the metal, these roofs are durable and typically last longer than asphalt roofs.
