Metal Roofing: Corrugated vs Standing Seam Metal Roofing: Corrugated vs Standing Seam

Metal roofing has long been admired for its impressive attributes. A metal roof is easy to install, is fire resistant, lasts a lifetime and requires virtually no maintenance. You can even install it over your existing roof.

Corrugated and standing seam are the two main types of metal roofing. But as a consumer, how do you choose the one that is best suited for your home?

Standing Seam Metal Roofing Basics

Standing seam metal roofing is constructed of interlocking metal panels that run from the ridge of the roof to the eave. The seams of the two panels are raised above the surface to allow the water to run off rather than seep between the panels. The seams are fastened to the roof using one of two methods. The first utilizes hidden anchors that are located on the raised portion of the panel.  The adjacent panel overlaps the raised edge hiding the fastener. The second method is less costly and uses exposed fasteners that are installed through the panel directly into the roof sheathing.

Standing seam metal roofs have the ability to withstand a wide range of climates from cold New England winters to hot and humid summers of the South. This makes them a popular choice no matter what region of the country you live in. In the past, installing metal roofing wasn’t the first choice of many homeowners given their industrial look. However, companies now offer this roofing in a wide range of colors and styles, helping shed its commercial image. The vertical lines of a standing seam metal roof can function as an architectural design element. In many ways, this system highlights the valleys, peaks and gables of the roof. Installing a metal roof can also save you money on your utility bills since these roofs have the ability to deflect the sun's rays.

Corrugated Metal Roofing Basics

Corrugated metal roofing consists of interlocking rippled metal sheets that are fastened directly to the roof sheathing. The resulting roof system is extremely durable and lightweight and is capable of lasting up to 50 years. Much like standing seam metal roofing, corrugated metal is fire resistant and capable of withstanding a wide range of climates. Corrugated roofing is also environmentally friendly since it is constructed of recycled materials.

Corrugated metal roofing has been around since the 1800s but has been primarily used for industrial and agricultural buildings. Their tendency to shows signs of rust after a few years has made them less appealing to homeowners. However, as companies developed better weather-resistant coatings and galvanizing techniques, the rust problem subsided and demand increased. Now they are gaining popularity among homeowners thanks to the wide range of colors and styles available. Their unique wave-like look adds a three dimensional aspect to the roof, yet another reason these roofs are being installed on more and more homes.

As builders and homeowners look for a cost effective and energy efficient alternative to traditional roofing the demand for metal roofing will continue to rise. Its ability to be installed in just about any region of the country, coupled with their ease of installation make them an ideal choice for a variety of applications.
