Commercial roofing systems play an important role in protecting businesses from the elements and maintaining a safe, functional workspace. A well-maintained roof can help prolong the lifespan of a building and keep it looking its best!

However, not all commercial roofing systems are created equal. There are several commercial roofing types available, each with its own set of benefits and drawbacks. In this article, we will discuss the most common types of commercial roofing systems and the importance of choosing a trusted professional for installation and maintenance. 

What is Commercial Roofing?

Commercial roofing refers to the installation, repair, and maintenance of roofing systems for commercial buildings such as offices, warehouses, and retail spaces. Commercial roofing differs from residential roofing in several ways, including the materials used, the size of the project, and the complexity of the installation. Commercial roofs, sometimes referred to as flat roofs, are typically larger and more complex than residential ones, and require more durable materials and specialized installation techniques. 

How Does Commercial Roofing Differ from Residential?

Commercial roofing systems are designed to withstand the unique challenges of accommodating large business buildings. Most commercial roofing material is designed for low slope flat roofs. A flat roof will have to be build differently because it doesn’t shed water the same way as a sloped roof. So the material, layers and installation requirements are unique.

Flat Roofing vs. Steep Slope Roofing

Flat roofing material is different than sloped roofing material because it has different needs. A flat roof needs to take into account things like the potential chance of ponding water. Where as a sloped roof will quickly shed the water.

Steep slope roofing material, such as shingles or slate, are more commonly used for residential roofing projects. Flat roofing systems are typically made of materials like EPDM (ethylene propylene diene monomer), TPO (thermoplastic olefin), and PVC (polyvinyl chloride). These materials are highly durable and weather-resistant, making them ideal for buildings with flat roofs.

Steep slope roofing systems are typically made of materials like asphalt shingles, metal, or slate. These materials provide excellent protection against weather damage and are highly durable. However, as stated previously, many steep slope roofing systems exist on residential homes rather than on businesses. 

Providing Energy Efficiency and Functionality

Commercial roofing systems can provide energy efficiency features such as insulated layers under the waterproofing, along with lighter color material that better reflects the suns heat. There is also a practical function to the flat roofs, that allows for HVAC equipment and even roof top decks. Some commercial building owners even go with green roof systems that install plants on the roof.

Popular Commercial Roofing Materials for Businesses

There are several popular commercial roofing materials available for businesses. Below are some of the most common types that our roofers work with. 

Single-Ply Membrane Roofing (TPO, PVC, and More)

Single-ply membrane roofing is a popular option for commercial roofing systems. This material is made of a single layer of synthetic materials, such as PVC or TPO (thermoplastic polyolefin), and is highly resistant to UV rays and weather damage. Single-ply membrane roofing is lightweight, durable, and easy to install, making it a popular choice for businesses.

TPO and PVC roofing systems are also highly reflective, which can help reduce cooling costs in the summer. These roofing systems have a life expectancy of up to 20 or 30 years with proper maintenance. 

EPDM Roofing

EPDM (Ethylene Propylene Diene Monomer) roofing is a rubber type material that is highly durable and weather-resistant, making it an ideal choice for commercial buildings. EPDM roofing can last up to 20 or 30 years with proper maintenance, making it a cost-effective option for businesses. 

Modified Bitumen Roofing

Modified bitumen roofing is a type of asphalt roofing that has been modified with additional polymers to increase its durability and weather resistance. Modified bitumen roofing is popular for commercial buildings due to its affordability and ease of installation. 

Built-Up Roofing (BUR)

Built-up roofing systems, also known as tar and gravel roofs, are made of several layers of materials, including bitumen and gravel. These roofing systems are highly durable and long-lasting, making them a sound investment for businesses of all kinds.

Metal Roofing

Metal roofing is a popular choice for commercial buildings due to its durability, longevity, and aesthetic appeal. Metal roofing systems are available in a variety of styles and colors, making them a versatile option for business owners. 

Other Types of Commercial Roofs

Other types of commercial roofs include liquid and roof coating systems, which involve applying a liquid coating to an existing roof to improve its durability and weather resistance. Another type is lesser-seen green roofing systems, which involve installing vegetation and soil on top of a roofing system, creating a natural barrier against weather damage.

Liquid and roof coating systems provide an additional layer of protection against weather damage. These systems can be applied to existing roofing materials and can greatly extend the life of commercial roofs. 

Green Roofing

Green roofing systems are environmentally friendly and can help reduce heating and cooling costs throughout the year. These new-age systems involve the installation of vegetation and soil on top of your roof, creating a natural green space that your roof, as well as the community around your building, can benefit from!
