Corrugated Metal Roofing

Commercial & Multi-Family Flat Roofs

Corrugated metal roofing is often the best choice of material for commercial purposes. However, most homeowners and HOA’s will not be in favor of a corrugated roof system in a residential area. Let's take a look at some of the advantages and disadvantages of corrugated roofing.


Water management

Corrugated roofing systems can help you quickly rid structures of water. Perfect for anyone in areas with heavy rainfall or rapidly changing climates!

Water can be the most damaging element to structures over time. As such, it’s important to quickly and properly divert the moisture to a location where it’s welcome. Properly designed systems can give you the best possible route for runoff, so make sure your contractor has experience with corrugated roofing.


Another important factor which gives corrugated metal roofing an advantage, is their weight. Maybe we should say, lack thereof. Other roofing systems such as slate, clay, or concrete can put a heavy burden on their structure below. Over time, the structure becomes more susceptible to cracks in the foundation and framing. Talk about some unexpected repairs!


It’s important to note that a corrugated roofing system can last nearly 100 years! Let’s say you have a business with commercial buildings you wish to pass on to your family or sell one day. Wouldn't it be nice to have one less thing to worry about? Corrugated roofing can give you that peace of mind! Also, corrugated roofing typically prevents algae growth over time due to its pre-treatment.



We need to mention that steel will corrode over time due contact with water. However, galvanized steel is much more resistant to corrosion. Zinc or aluminum can protect the steel core of the corrugated roof, increasing its lifetime. Make sure you know what type of material you are purchasing before starting a project.

Another tip to increase the lifespan of your corrugated roof is to make sure there’s no material contact with copper, graphite, or lead. When selecting material for other roofing components such as pipe-jacks or vents, you should avoid these at all costs as they are corrosive to metals.

Let’s end on a high note here! Corrugated roofing systems are much more durable against weather and ‘’Acts of God’’ as insurance companies call them. This reduces the premiums you pay! Woohoo!
