If you own a commercial property you likely know a thing or two about maintenance — because for commercial properties the maintenance is usually constant. If one thing is finally fixed, something else has probably already broken. If there is one thing that you do not want to worry about on your commercial property, it is your roof.

In today’s blog post we will be discussing some of the different types of commercial roofing, the advantages of each roofing style, and the disadvantages of each roofing style so that next time you need a commercial roof replacement you can choose the roofing style most fit to benefit your commercial property.

Commercial Flat Roofs

When it comes to commercial buildings, flat roofs are among the most common. Most large warehouses and other buildings with large square footage are built with commercial flat roofs. But what are the advantages and disadvantages?


The largest advantage that commercial property managers see when choosing to install a flat roof is the cost-effectiveness. Because flat roofs do not have a pitch, they use much fewer materials — thus reducing cost. Additionally, commercial flat roofing can be built using many different roofing materials, meaning that they can be made to be more efficient than some other types of commercial roofing.


When it comes to commercial flat roofing there is really one disadvantage, and it can be small or large. Flat roofing is known to have water-related issues. Now, we don’t want to scare you away from the idea of commercial flat roofing, but it should be known that if the roofing is not installed properly, or if it is not maintained on a regular basis, that water pooling and leaks can develop.

Commercial Low-Sloped Roofs

Commercial low-sloped roofs are exactly what they sound like — roofs that are not flat, but instead have a very minimal slope to promote runoff. In fact, sometimes the slope of the roof is so minimal that you would not even be able to tell it is angled unless you were up on the roof yourself.


The largest advantage of a low-slope roof is that it is still cost-effective because it requires minimal materials, but it also addresses the water issue posed by flat roofing. Additionally, low-sloped roofing allows for safer working conditions during routine roof management.


When it comes to disadvantages of low-sloped roofing there are few, but the largest issue is the inability of the roofing style to deal with large volumes of snow. Because the angle of the roof is minimal, snow might have issues sliding off and will instead pile on the roofing system.

Commercial Metal Retrofit  Roofing

Metal roofing is not often thought of as a viable commercial roofing material. Traditional metal roofing can be expensive and hard to maintain, but metal retrofit roofing is an excellent option for older metal roofing systems that are no longer capable of functioning.


Metal retrofit roofing is an extremely cost-effective way to refinish an existing metal roof instead of replacing it. Additionally, it allows for day-to-day-operations inside of the building to operate while the roof is being refinished — as the new membrane is simply installed on top of the older metal roof.


While retrofit roofing is a wonderful way to refinish a roof, adding nearly 20 years of lifetime to the roofing system, it is not as effective as new roof installations. For example, if the roofing system were to be completely refinished, it would get an additional 60 years of lifetime.

Choosing What is Best For You

As a commercial property manager you have to make a series of calculated decisions that extend the lifetime and functionality of the building — and choosing a roofing style and material is a huge part of that.

There are many factors that might influence your decision as to what roofing style is best for your building. How much money do you have? How long is there until your long-term property lease is up? What is the climate in the city where your building is located? All of these questions and more will influence what roof is best — and Nice Shingles Roofing & Exteriors can help you choose.
