Types of Commercial Metal Roofs

Metal roofs go great with commercial and industrial buildings that have low sloped roofs. As metal is waterproof, fireproof, and can resist chemicals, it is a favorite among warehouses and other industrial businesses that see a lot of high heat. Other roofing systems would collapse from the extreme temperature fluctuations, but metal roofing can withstand it all, including any type of storm.

Corrugated Metal

The most popular type of commercial metal roofing system, corrugated metal provides the typical industrialized look. This is because the metal bolts are shown connecting the metal panels. Even with the hardware exposed, this does not hinder the durability of a corrugated metal roof. Instead, corrugated metal roofing is one of the most durable metal roofing systems available, though maybe not the most attractive. Corrugated commercial roofs come in two types of styles: U-Panel and R-Panel. U-Panel corrugated roofs are 26 gauge, while R-Panel roofs are 29 gauge. the difference in width is mainly for aesthetic purposes, as the wider R-panel roofs are found to be more appealing on sales businesses. Corrugated metal roofs have some of the longest lifespans out of any metal roofs, lasting up to 50 years.

Standing Seam

For a slightly more attractive metal roof, go with standing seam metal roofing. Basically the same as a corrugated metal roof but without the bolts showing,standing seam gets its name because it gives off a seamless appearance. There are two types of standing seam roofing types to choose from: snap lock or mechanical lock. Snap lock roofs are for sloped roofs and are primarily seen on residential or highly sloped commercial roofs. Mechanical lock roofs are more common for low slope industrial or commercial buildings.


As the most lightweight metal roof available, that does not mean that steel is fragile. Coming with a zinc coating to help prevent rusting, steel withstands all storm types and won’t weather over time from age. Very similar to steel is aluminum, coming in at the second most lightweight metal roofing system. Steel is available in two types: galvalume and galvanized. Galvalume steel is a steel roof that has a mixture of zinc and aluminum coating on top of it. This coating helps to prevent rusting, but even without the coating, galvalume steel roofs have been recorded as surviving up to 40 years. Galvanized steel roofs are completely dipped in zinc to provide a rust-free coating.


The second most lightweight metal roof available, aluminum is the only one that is naturally rust-resistant. This is beneficial as it means that you can save a little money by not having to purchase an additional roof coating to help keep your metal roof from rusting. A lot of coastal commercial buildings have aluminum roofs, as they don’t have to worry about the sea salt air causing the roof to degrade quickly. While aluminum does not require a roof coating, a lot of people still opt for it because the natural metal will still show scratches and age over time.

Stone Coated Steel

Stone coated steel is seen more on sloped commercial roofs, since the metal panels covered in stone chips cannot adequately cover a flat roof without resulting in leaks and other water damage. Stone coated steel roofs can emulate many different styles of roofing, from slate to tile, all while still having a metal base to provide the strong and long lasting protection. Having a stone coated steel roof is recommended for more aesthetic commercial properties like hotels or sales businesses.

Metal Shingles

Similar to stone coated steel panels, metal shingles are actually shingles instead of panels imitating the look of shingles like stone coated steel does. Physically consisting of cut up metal pieces to create shingles, you are given the best of both worlds in that you are provided the durability of metal but the look of a more residential roof. This is beneficial if your commercial building is in a more suburban area and you don’t want to stand out too much, or if your line of commercial work does not require a heavy duty industrial-looking roof.

Metal roofs last a minimum of 50 years when properly installed. They are Energy Star approved due to their high levels of energy efficiency and reflectivity. This means that your building will stay cooler as the metallic roofing panels reflect the sunlight instead of absorbing it, helping to lower energy bills as well.
