The Major Difference Between Corrugated and Standing Seam Metal Roofs

Metal roofing is efficient, but most Littleton, CO roofers you can count on with years of experience and knowledge will tell you that you have to choose the right kind of metal roofing variant. Corrugated metal roofs are more affordable steel or aluminum metal roofing. However, most will recommend standing seam metal roofs because of their exceptional durability and beautiful aesthetic.

There are a great many differences between corrugated and standing seam metal roofs. In the many installations and repairs we've done throughout the years, we've seen more corrugated roofing repair cases than standing seam metal roofs. Corrugated metal roofs are quite durable, but they're not as durable and dense as standing seam metal roofs. Their exposed gaskets make them prone to leakage and further damage.

Standing seam metal roofs have concealed gaskets, but they're very expensive initial investments. Additionally, homeowners will need to invest further in improving their roofing joists and support structures because these roofs can be quite heavy. However, the payoff is immense with over 50-70 years of average lifespan. With effective maintenance, it can even last for more than 100 years.

1) Design and Appearance

If the term corrugated metal roofing sounds a bit confusing, chances are you probably doesn't know what corrugated means. Corrugated describes anything with a surface that is shaped into alternate ridges and grooves. Put simply, a corrugated metal roof is one with interlocking rippled metal sheets. A standing seam metal roof, on the other hand, is constructed of interlocking metal panels that run from the ridge of the roof to the eave. Its design and texture makes it not only a better system for shedding water and snow, but also an ideal solution for low-pitched roofs.

2) Fastening Systems

Besides the aesthetic difference of the two roofs, the fastening system of standing seam metal roofs is better and more reliable. Whereas the interlocking rippled metal sheets of a corrugated metal roof are fastened directly to the roof sheathing, the seams of a standing seam metal roof are raised above the surface. The screws are completely concealed and safely protected by the roof surface, giving standing seam metal roofs a streamlined look that can never be created by its counterpart. As for durability and material quality, explains that “standing seam roofs are generally made from thicker grades of steel than corrugated steel roofs. While many corrugated steel roofs are made using a very thin 29 gauge steel, a minimum of 26 gauge galvalume steel is used for manufacturing of standing seam panels. (Continued)
