Most Common Types of Commercial Roofs

Within the wider construction industry, roofing is the 16th biggest branch. Once made of straw, leaves, and branches, today’s commercial roofs are made more sophisticated and durable. Old or modern roofing systems share one common goal: to protect commercial buildings from external conditions like bad weather. Other than this shared quality, the size, slope, and materials of commercial roofs can differ greatly.  Commercial roofs can be made from different materials that provide resistance against extreme weather conditions and keep your heating and cooling costs low. Read on to learn which materials work the best for which commercial property and how to choose the right option for you. 

Metal Roofing

Metal is a very common material used in commercial roofs as it’s durable, long-lasting, and appealing. It can be made from steel, aluminum, copper, and tin. Some metal roofs also have integrated solar panels or snow removers. However, metal roofs are susceptible to corrosion, which is the only downside of installing them. Newer metal roofs have a protective surface layer that keeps the metal shiny and protects it from corrosion. 

Built-up Roofing 

You may have seen this type of roof, as many businesses opt for a built-up roofing membrane. It’s made up of alternating layers of tar and gravel and usually consists of 3-5 layers for protection. This type of roof has been around for a long time as it holds up well to foot traffic and can be UV resistant. The drawback to this roofing type is its short lifespan, even with maintenance. 

Thermoset EPDM Roofing

Ethylene Propylene Diene Terpolymer (EPDM) offers resistance to sunlight and pollution. This synthetic rubber roofing is easy to apply as it comes in rolls, and depending on the color, it can also be sun resistant. This type of roofing is flexible and robust and is mainly used on low-slope buildings. The only downside is that it can be easily punctured and is not the prettiest to look at.

TPO/PVC Single-ply Membrane Roofing

Thermoplastic roofing membranes allow maximum durability as well as flexibility even during harsh weather conditions. This type of roof can ensure longevity and adjustability based on an already installable and multipurpose product.  Both roofing systems can be used with mechanically attached, ballasted and entirely adhered applications. 

Shingle Roofing

This type of roofing can be seen more commonly on residential buildings rather than commercial ones. It’s also an important design feature of the building and essential for aesthetic appeal. The material depends on the roof’s steepness, whereas the roof is easy to install, affordable and versatile. On the flip side, it can be susceptible to moss and mildew and has a short lifespan.

Spray-on Roofing 

Spray Polyurethane Foam (SPF) is used when you want to opt for an eco-friendlier roofing type. SPF is applied as a spray, which instantly expands into foam and hardens once dry. Even though it’s not well known, it has been around since the 1960s and can be applied to any existing roof. It provides a layer of insulation from extreme weather. When applied correctly, it’s durable, seamless, and waterproof. 

Green Roofs

Green roofs can reduce energy costs and make the workspace more enjoyable for your employees. This type of roof consists of a waterproof membrane placed on a pre-existing roof and topped with different types of plants. This roof improves air quality, offers natural insulation, and lessens the need for complex drainage systems.  The only disadvantage is the need for regular maintenance and upkeep.
