5 Commercial Roof Types Every Business Owner Must Know

Did you know there are significant differences between commercial and residential roof types? Both share the same function and solve the purpose of protecting the properties from the elements. However, those similarities end there.

The major difference between the two types of roofing is the slope, which is usually determined by the property size. Residential buildings have steeper slopes due to their smaller size. Commercial properties tend to have flats or slightly sloped roofs due to their larger size.

This guide will look at the different types of commercial roofing systems. Comparing all the different commercial roofing types will help you determine the best possible roofing option for your property.

1. Metal Roofing Systems

Metal roofing systems are some of the most durable commercial roof types, with about 60 years of life span. When it comes to metal roofs, there are several types of metals you can choose from for your commercial property. Some of the most common metal roofing materials include aluminum, zinc, copper, corrugated galvanized steel, tile sheets, and coated or stainless steel.

Some metal roofing systems also come integrated with snow removal or solar systems. Different metal materials can be integrated or incorporated together to create robust, durable roofing systems. Metal roofs are some of the most attractive, as they feature a beautiful finished look and a robust fire-resistance rating.

They are also some of the strongest and most sustainable compared to other commercial roof types. The only possible downside to metal roofs is that they’re susceptible to corrosion. Even then, with modern technology, this can be a non-issue because modern metal roofs feature protective surface layers.

These layers are meant to protect the roof from damage caused by moisture, pollution, exposure to elements, and various environmental factors.

2. PVC or TPO Roof Membranes

Polyvinyl chloride, PVC, or Thermoplastic Polyolefin TPO roofing systems are some of the best commercial roof types on the market. They resist adverse conditions and slow to damage from UV light, chemicals, or bacterial growths. Some of their most significant benefits are that they’re heat-reflective, lightweight, and puncture-resistant.

Even better, PVC and TPO roofs are resistant to fire. They have very strong air-welded seams and very well tolerate high winds and high temperatures. These reasons make them some of the best types of commercial roofing systems.

However, during the installation process, you should be cautious not to get cheap or substandard materials. TPO has especially become incredibly popular. Numerous manufacturers are now trying to create their own product lines.

In turn, the quality of the products seems to have slipped through the cracks, and many low-quality materials are being sold on the market. Ensure you get your roofing materials from a reputable manufacturer. Hire professional installers for quality workmanship as well.

3. Shingle Roofing Systems

Shingles are some of the market’s most popular types of commercial roofing materials. However, they are also used for commercial properties with steep rooflines.

There are so many shingles, starting with asphalt, which is the most common. There are also architectural, ceramic, slate, and even plastic, to name a few.

Shingles are some of the most affordable, versatile, and easy-to-install commercial roofing materials. The only notable downside of a shingle roofing system is that it may not be as durable as most other commercial roof types. Shingles are also susceptible to moss and mildew if the property is shaded.

4. Spray-On Roofing

Spray-on roofing, also known as SPF, is a roofing material that starts as a liquid spray. When sprayed, it expands into foam, then hardens and becomes a solid layer. If you’re looking for an eco-friendly commercial roofing option, spray-on roofing is a good choice.

It can be applied on an existing roof, and some of the best advantages of this roofing option are that it adds an insulating factor and is waterproof. The proper installation from a professional roofing company can last up to 50 years and be used in any climate. Installation should be done during favorable weather conditions with no ice, water, or snow.

5. Commercial Cool Roofing

Sometimes you don’t need to install a completely new roofing system. You can repair the existing roof to make it “cool.”

A cool roof reflects heat and sunlight, thus keeping the interior temperatures cooler. A cool roof will extend the lifespan of your roof and lower your business energy consumption more than the standard roofing systems. In Los Angeles, the summer average maximum temperature is around 93 degrees Fahrenheit. This means that a commercial roof can reach temperatures up to 150 degrees Fahrenheit on a hot day. Cool roofs can reduce the amount of heat that flows into an occupied space, saving energy and money in buildings with air conditioning or improving comfort and safety in buildings without air conditioning by reducing heat flow from the roof into the occupied space.

So, what determines if a roofing system is cool?

There are many roofing materials, but the outermost surface determines if the roof can reflect back heat and light. You can even cool an existing roof by adding a coating.

If you’re looking for a roof coating, there are two options you’d want to know: acrylic and silicone roof coatings.

Acrylic coating is meant to stop UV light. It can be applied to metal systems and single-ply membranes. And apart from providing radiation resistance, acrylic coating is also good in resisting hail damage.

Silicone coating, just like acrylic coating, is very good at reflecting UV light. But apart from that, it performs exemplary well in rainy environments due to its ability to withstand pooling water.
