What Are the Most Popular Commercial Roofing Materials?

Choosing commercial roofing materials is a big decision. If you’re in charge of the construction or renovation of a commercial building, you’re probably wondering about your options. Since you’ll be making a large investment, you need to make an informed choice. This blog will look at some of the most common roofing materials for commercial buildings. However, you should reach out to a roofer in Greenville, SC for recommendations regarding your project. 


Most people associate metal with commercial roofs since it has been used for this purpose for so long. Corrugated galvanized steel is the most popular, but tin or aluminum can also be used. Since metal is lightweight, it can be installed on top of an existing roof.  The material can then be coated to protect against water, rust, and ultraviolet rays. Metal roofing systems can last for 40 years and they are available in several colors. They can stand up to both high winds and fire. Some sheet metals are made from recycled materials and this is a selling point for eco-conscious building owners.

Asphalt and Architectural Shingles

Shingles are common on residential projects, but they are also used for steep-slope commercial roofs. They can be made from asphalt, wood, metal, ceramic, plastic or slate, among other materials. Asphalt shingles are popular, partly because of their cost-effectiveness and they usually have a 15 to 30-year warranty. Meanwhile, architectural shingles are heavier and layered. They are more durable, and they often come with lifetime warranties. Shingle roofs are available in a wide range of colors and designs and they can be easily repaired.

Spray Polyurethane Foam Roofing

Spray Polyurethane Foam (SPF) is another option for commercial projects. It is sprayed out as a liquid over an existing roof and it expands into a foam. When it is correctly installed and maintained, it can last for more than 50 years. SPF offers several benefits including durability. The material expands and contracts with the building and this helps to keep splits and cracks at bay. 

SPF is seamless and this reduces the likelihood of leaks. The material is also highly energy-efficient and environmentally friendly. There is usually no need to tear off the original roof and the materials are free from chlorofluorocarbons and low in the emission of volatile organic compounds. Roofing contractors in Greenville, SC can help you to decide if this is right for you.

Single-Ply Membrane 

This is one of the most well-known commercial roofing materials and it has a proven track record. Single-ply membranes are synthetic sheets made from rubber and other materials. They can be mechanically fastened, stuck or ballasted to your choice of insulation for industrial, commercial and manufacturing structures. Several types of membranes are available to suit your budget and the needs of your building. 

Roofs that are properly installed and regularly maintained can last for up to 30 years.  Thermoplastic polyolefin (TPO) and ethylene propylene diene terpolymer (EPDM) can have Class A fire resistance ratings. You can choose your materials based on whether you want to reflect or retain heat.

Built-Up Roofing

Tar and gravel roofing has been used in the United States for more than a century. It is the most common solution for low-slope roofs. Built-up roofing systems are installed by adding layers of asphalt or tar and supporting fabrics right onto the roof. The last layer is made of gravel or stone. These roofs have a lifespan of up to 40 years, especially in warmer climates. Since they are seamless, the likelihood of leaks is reduced. Built-up roofs are low-maintenance and they provide ultraviolet protection. The top layer also makes them fire-resistant.
